** Incompatible changes

*** Agenda: rework ndays and span handling
    
The variable =org-agenda-ndays= is obsolete - please use
=org-agenda-span= instead.

Thanks to Julien Danjou for this.

** Details

*** Improvements with inline tasks and indentation

There is now a configurable way on how to export inline tasks.  See
the new variable =org-inlinetask-export-templates=.

Thanks to Nicolas Goaziou for coding these changes.

*** Agenda: Added a bulk "scattering" command
    
=B S= in the agenda buffer will cause tasks to be rescheduled a random
number of days into the future, with 7 as the default.  This is useful
if you've got a ton of tasks scheduled for today, you realize you'll
never deal with them all, and you just want them to be distributed
across the next N days.  When called with a prefix arg, rescheduling
will avoid weekend days.

Thanks to John Wiegley for this.

*** In-buffer completion is now done using John Wiegleys pcomplete.el

Thanks to John Wiegley for much of this code.

*** Sending radio tables from org buffers is now allowed

Org radio tables can no also be sent inside Org buffers.  Also,
there is a new hook which get called after a table has been sent.

Thanks to Seweryn Kokot.

*** Command names shown in manual

The reference manual now lists command names for most commands.
Thanks to Andreas Röhler who started this project.

*** Allow ap/pm times in agenda time grid

Times in the agenda can now be displayed in am/pm format.  See the new
variable =org-agenda-timegrid-use-ampm=.  Thanks to C. A. Webber for
a patch to this effect.

*** Rewriten clock table code 

The entire clocktable code has been rewritten to add more options and
to make hacking time reports easier.

Thanks to Erwin Vrolijk for a patch introducing clock tables for
quarters.

*** Babel
**** Add =msosql= engine to sql code blocks
SQL code blocks can now be executed using the =myosql= engine on
Windows systems.

Thanks to Sébastien Vauban for this contribution.

**** Python code blocks now accept a =preamble= header argument
This allows specification of coding declarations and library imports
which must take place in the beginning of a file of executed python
code (note this header argument is used during code block evaluation
unlike the =shebang= header argument which is used during tangling).
For example

#+begin_src org
  ,#+begin_src python :preamble # -*- coding: utf-8 -*- :return s
  ,s = "é"
  ,#+end_src
#+end_src

Thanks to Vincent Beffara for this idea.

**** Code block name is shown during evaluation query
When the user is queried about the evaluation of a named code block
the name of the code block is now displayed.

Thanks to Tom Dye for this suggestion.

**** Clojure code blocks results insertion
The results of Clojure code blocks have been improved in two ways.
1. lazy sequences are now expanded for insertion into the Org-mode
   buffer
2. pretty printing of results is now possible with both "code" and
   "data" pretty print formats

Thanks to Rick Moynihan for suggesting these changes.

**** Python code blocks now accept a =:return= header argument
This alleviates the need to explicitly insert return statements into
the bode of Python code blocks.  This change both
- allows the same python code blocks to be run both in sessions and
  externally
- removes the floating =return= statements which violated python
  syntax

Thanks to Darlan Cavalcante for proposing this feature.

**** =:results wrap= header argument wraps code block results
The new =:results wrap= wraps code blocks results in a custom
environment making it possible to offset their contents during
export.  For example

#+begin_src org
  ,#+begin_src emacs-lisp :results wrap
  ,  "code block results"
  ,#+end_src
  
  ,#+results:
  ,#+BEGIN_RESULT
  ,: code block results
  ,#+END_RESULT
#+end_src

Thanks to Sébastien Vauban for persistently suggesting this enhancement.

**** Code block error buffer wiped clean between executions
Previously the code block error buffer accumulated errors making it
difficult to distinguish between previous and current errors.  This
buffer is now cleaned before every interactive code block evaluation.

**** Lists now recognized by code blocks
It is now possible for code blocks to both read and write list
contents from and to Org-mode buffers.  For example

#+begin_src org
  ,#+results: a-list
  ,- babel
  ,- and
  ,- org-mode
  
  ,#+source: a-list
  ,#+begin_src emacs-lisp :var lst=a-list :results list
  ,  (reverse lst)
  ,#+end_src
#+end_src

**** Calc added as a supported code block language
The Emacs Calc package can be used through =calc= code blocks allowing
both regular arithmetic operations as well as stack based
calculation.  For example

#+begin_src org
  ,#+source: calc-stack
  ,#+begin_src calc
  ,  8
  ,  1
  ,  '+
  ,  9
  ,  '*
  ,#+end_src
  
  ,#+results: calc-stack
  ,: 81
  
  ,#+source: calc-arithmetic
  ,#+begin_src calc :var in=calc-stack
  ,  in / 9
  ,#+end_src
  
  ,#+results: calc-arithmetic
  ,: 9
#+end_src

**** "org-babel-detangle" propagates change to source code files into code blocks
`org-babel-detangle' can be used to propagate changes to pure source
code files tangled from embedded code blocks in Org-mode files back to
the original code blocks in the Org-mode file.  This can be used on
collaborative projects to keep embedded code blocks up to date with
edits made in pure source code files.








* Version 7.02

:PROPERTIES:
:CUSTOM_ID: v7.02
:END:

** Incompatible Changes
*** Code block hashes
Due to changes in the code resolving code block header arguments
hashing of code block results should now re-run a code block when
an argument to the code block has changed.  As a result of this
change *all* code blocks with cached results will be re-run after
upgrading to the latest version.

*** Testing update
Anyone using the org-mode test suite will need to update the jump
repository for test navigation by executing the following from
the root of the org-mode repository.
: git submodule update
Failure to update this repository will cause loading of
org-test.el to throw errors.
** Details
*** Org-babel speed commands
All Org-babel commands (behind the C-c C-v key prefix) are now
available as speed commands when the point is on the first line of a
code block.  This uses the existing Org-mode speed key mechanisms.

Thanks to Jambunathan K for implementation this new feature.

*** Fontify code in code blocks.

Source code in code blocks can now be fontified.  Please customize the
varable =org-src-fontify-natively=. For very large blocks (several
hundreds of lines) there can be delays in editing such fontified
blocks, in which case C-c ' should be used to bring up a dedicated
edit buffer.

Thanks to Dan Davison for this.

*** Language-mode commands are available in the Org-buffer
    The most general machinery for doing this is the macro
    `org-babel-do-in-edit-buffer'. There is also the convenience
    function `org-babel-do-key-sequence-in-edit-buffer' which makes
    use of this macro, and is bound to C-c C-v C-x and C-c C-v x. If
    there is an active region contained within the code block, then
    this is inherited by the edit buffer. Some examples of the sorts
    of usage this permits are

C-c C-v C-x M-;       comment region according to language
C-c C-v C-x C-M-\     indent region according to language

Users can make these more convenient, e.g.

(defun my/org-comment-dwim (&optional arg)
    (interactive "P")
    (or (org-babel-do-key-sequence-in-edit-buffer "\M-;")
        (comment-dwim arg)))

(define-key org-mode-map "\M-;" 'my/org-comment-dwim)

A common instance of this general pattern is built in to Org-mode,
controlled by the variable `org-src-tab-acts-natively': if this
variable is set, then TAB in a code block has the effect that it would
have in the language major mode buffer.

*** Org-babel commands are available in language-mode edit buffer
    Mirroring the language-native commands in Org buffers above, a new
    macro `org-src-do-at-code-block' and convenience function
    `org-src-do-key-sequence-at-code-block' provide the converse. When
    used in a language major-mode edit buffer (i.e. a buffer generated
    by C-c '), `org-src-do-key-sequence-at-code-block' executes a key
    sequence at the code block in the source Org buffer.  The command
    bound to the key sequence in the Org-babel key map is executed
    remotely with point temporarily at the start of the code block in
    the Org buffer.

    The command is not bound to a key by default, to avoid conflicts
    with language major mode bindings. To bind it to C-c @ in all
    language major modes, you could use

  (add-hook 'org-src-mode-hook
            (lambda () (define-key org-src-mode-map "\C-c@"
                    'org-src-do-key-sequence-at-code-block)))

    In that case, for example, C-c @ t issued in code edit buffers
    would tangle the current Org code block, C-c @ e would execute
    the block and C-c @ h would display the other available
    Org-babel commands.

*** Multi-line header arguments to code blocks
Code block header arguments can now span multiple lines using the
new =#+header:= or =#+headers:= lines preceding a code block or
nested in between the name and body of a named code block.
Examples are given below.

- multi-line header arguments on an un-named code block
  : #+headers: :var data1=1
  : #+begin_src emacs-lisp :var data2=2
  :   (message "data1:%S, data2:%S" data1 data2)
  : #+end_src
  : 
  : #+results:
  : : data1:1, data2:2

- multi-line header arguments on a named code block
  :   #+source: named-block
  :   #+header: :var data=2
  :   #+begin_src emacs-lisp
  :     (message "data:%S" data)
  :   #+end_src
  : 
  :   #+results: named-block
  :   : data:2

*** Unified handling of variable expansion for code blocks
The code used to resolve variable references in code block header
arguments has now been consolidated.  This both simplifies the
code base (especially the language-specific files), and ensures
that the arguments to a code block will not be evaluated multiple
times.  This change should not be externally visible to the
Org-mode user.
*** Improved Caching
Code block caches now notice if the value of a variable argument
to the code block has changed, if this is the case the cache is
invalidated and the code block is re-run.  The following example
can provide intuition for the new behavior.
#+begin_src org :exports code
  ,#+srcname: random
  ,#+begin_src R :cache yes
  ,runif(1)
  ,#+end_src
  
  ,#+results[a2a72cd647ad44515fab62e144796432793d68e1]: random
  ,: 0.4659510825295
  
  ,#+srcname: caller
  ,#+begin_src emacs-lisp :var x=random :cache yes
  ,x
  ,#+end_src
  
  ,#+results[bec9c8724e397d5df3b696502df3ed7892fc4f5f]: caller
  ,: 0.254227238707244
#+end_src

*** Added :headers header argument for LaTeX code blocks
This makes it possible to set LaTeX options which must take place in
the document pre-amble for LaTeX code blocks.  This header argument
accepts either a single string or a list, e.g.

#+begin_src org
  ,#+begin_src latex :headers \usepackage{lmodern} :file name1.pdf
  ,  latex body
  ,#+end_src
  
  ,#+begin_src latex :headers '("\\usepackage{mathpazo}" "\\usepackage{fullpage}") :file name2.pdf
  ,  latex body
  ,#+end_src
#+end_src

*** New function `org-export-string'
Allows exporting directly from a string to the specified export format.
*** Code block header argument ":noweb tangle"
Only expands <<noweb>> syntax references when tangling, not during
export (weaving).
*** New function `org-babel-switch-to-session-with-code'
C-c C-v z (`org-babel-switch-to-session-with-code') is a variant of
C-c C-v C-z (`org-babel-switch-to-session'): instead of switching to
the session buffer, it splits the window between (a) the session
buffer and (b) a language major-mode edit buffer for the code block in
question. This can be convenient for using language major mode for
interacting with the session buffer.

*** Improvements to R sessions
    R now uses standard ESS code evaluation machinery in the :results
    value case, which avoids unnecessary output to the comint
    buffer. In addition, the R command responsible for writing the
    result to file is hidden from the user.  Finally, the R code edit
    buffer generated by C-c ' is automatically linked to the ESS
    session if the current code block is using :session.

*** Temporary file directory
All babel temporary files are now kept in a single sub-directory in
the /tmp directory and are cleaned up when Emacs exits.

*** Function for demarcating blocks `org-babel-demarcate-block'
Can be called to wrap the region in a block, or to split the block
around point, bound to (C-c C-v d).

*** Function for marking code block contents `org-babel-mark-block'
    Bound to C-M-h in the babel key map (i.e. C-c C-v C-M-h by
    default).  This can be useful in conjunction with
    `org-babel-do-in-edit-buffer', for example for language-native
    commenting or indenting of the whole block.
*** Lists of anniversaries are now handeled better

When several anniversaries are defined in the bbdb anniversaries
field (separated by semicolon), this is now handled nicely by the
agenda.

Thanks to Łukasz Stelmach for a patch to this effect.

*** Table fields are now aligned better, new <c> cookie.

In HTML export, table fields are now properly aligned in accord
with automatic alignment in org, or as set by the =<r>=, =<l>=, and
=<c>= cookies.  The =<c>= cookie is new and has no effect in
Org, but it does do the right thing in HTML export.  A LaTeX export
implementation will follow, but is currently still missing.

*** Update freemind converter to include body text

The freemind exporter now incorporates body text into the mind
map. 

Thanks to Lennard Borgman for this patch.
    
*** Make footnotes work correctly in message-mode
The footnotes code now searches for =message-signature-separator=
(which is "-- " by default) in order to place footnotes before the
signature.  Thanks to Tassilo Horn for this patch.

*** Improve XEmacs compatibility

Org-mode 7.02 now runs again in 21.4.22 if the new XEmacs base
package is installed.

Thanks to Uwe Bauer, Volker Ziegler, Michael Sperber and others
for a discussion that lead to this nice result.
    
*** Make it configurable wether agenda jumping prefers the future

When jumping to a date from the agenda using the =j= key, you may
or may not like the property of Org's date reader to prefer the
future when you enter incomplete dates.   This can now be
configured using the variable =org-agenda-jump-prefer-future'.

*** Add publishing functions for ASCII, Latin-1 and UTF-8

There are now publishing functions =org-publish-org-to-ascii=,
=org-publish-org-to-latin1=, and =org-publish-org-to-utf8=. 

Thanks to Matthias Danzl for showing how to do this.

*** Indentation and headline insertion after inline tasks

Indentation in inline tasks, and headline insertion after inline
tasks now behave as expected.

*** Encryption in MobileOrg finally works

As soon as MobilOrg 1.5 hits the Apple's AppStore, you can
encrypt your org files on public servers.  Please see the
documentation of MobileOrg and Appendix B of the manual for more
details.
    
*** MobileOrg: Do not force to insert IDs

If you dislike the property of MobileOrg to insert ID properties
for in all entries being part of an agenda view, you can now turn
this off using the variable
=org-mobile-force-id-on-agenda-items=.  When this variable is set
to =nil=, MobileOrg will use outline paths to identify entries.
Note that this may fail if several entries have identical outline
paths.

*** LaTeX minted package for fontified source code export
Patch by Dan Davison.

A non-nil value of `org-export-latex-minted' means to export source
code using the minted package, which will fontify source code
with color.  If you want to use this, you need to make LaTeX use the
minted package. Add minted to `org-export-latex-packages-alist', for
example using customize, or with something like

  (require 'org-latex)
  (add-to-list 'org-export-latex-packages-alist '("" "minted"))

In addition, it is neccessary to install
pygments (http://pygments.org), and to configure
`org-latex-to-pdf-process' so that the -shell-escape option is
passed to pdflatex.

*** Allow to use texi2dvi or rubber for processing LaTeX to pdf

Please see the variable =org-export-latex-to-pdf-process= for
more information.

Thanks to Olivier Schwander for the rubber part.

*** New STARTUP keywords to turn on inline images

If you want to inline images whenever you visit an Org file, use

: #+STARTUP: inlineimages
 
*** Support for user-extensible speed commands.

There is a new hook =org-speed-command-hook=.  Thanks to
Jambunathan for a patch to this effect.

*** Add macro to insert property values into exported text

you can use {{{property{NAME}}}} to insert the value of a
property upon export.

Thanks to David Maus for a patch to this effect.

*** LaTeX package fixes

We updated the list of default packages loaded by LaTeX exported
files.

*** Allow "#" and "%" in tags

Tags can now also contain the characters =#= and =%=, in addition
to =@= and letters.

*** Show command names in manual

Andreas Röhler is adding command names to keys in the manual.
This will take a while to complete, but a start has been made.

*** Make backslash escape "-" in property matches

When entering a tags/property query, "-" is a logical operator.
However, "-" is also allowed in property names.  So you can now
write "SOME\-NAME" to work around this issue.

This was a request by Ilya Shlyakhter.
    
*** Document quick insertion of empty structural elements

Org-mode has a built-in template mechanism for inserting block
templates.  This was undocumented until now.

Thanks to Jambunathan K for the patch.

*** Implement MathJax support

Org-mode now uses MathJax to display math on web pages.  We serve
MathJax from the orgmode.org server, at least for the time being
(thanks Bastien!).  If you are going to use this for pages which
are viewed often, please install MathJax on your own webserver.

To return to the old way of creating images and inserting them
into web pages, you would have to set

: (setq org-export-with-LaTeX-fragments 'dvipng)

or on a per-file basis

: #+OPTIONS: LaTeX:dvipng
    
*** Agenda: Allow compact two-column display in agenda dispatcher

If you have many custom agenda commands, you can have the display
in the dispatcher use two columns with the following settings

: (setq org-agenda-menu-show-match nil
:       org-agenda-menu-two-column t)

This was a request by John Wiegley.

*** Add org-wikinodes.el as a contributed package

One frequent request has been to be able to use CamelCase words
for automatic cross links in a Wiki created by Org.  THis is now
possible with org-wikinodes.el, which is available in the contrib
directory.  We also have some [[http://orgmode.org/worg/org-contrib/org-wikinodes.php][documentation]] for this feature up
on Worg.

*** Timer/clock enhancements

=org-timer-set-timer= displays a countdown timer in the modeline.
From the agenda, `J' invokes =org-agenda-clock-goto=.

* Version 7.01
:PROPERTIES:
:CUSTOM_ID: v7.01
:END:

** Incompatible Changes

*** Emacs 21 support has been dropped

Do not use Org mode 7.xx with Emacs 21, use [[http://orgmode.org/org-6.36c.zip][version 6.36c]] instead.

*** XEmacs support requires the XEmacs development version

To use Org mode 7.xx with XEmacs, you need to run the developer
version of XEmacs.   I was about to drop XEmacs support entirely,
but Michael Sperber stepped in and made changes to XEmacs that
made it easier to keep the support.  Thanks to Michael for this
last-minute save.  I had hoped to be able to remove
xemacs/noutline.el from release 7 by moving it into XEmacs, but
this is not yet done.

*** Org-babel configuration changes
:PROPERTIES:
:CUSTOM_ID: ob-configuration-changes
:END:

Babel took the integration into Org-mode as an opportunity to do
some much needed house cleaning.  Most importantly we have
simplified the enabling of language support, and cleared out
unnecessary configuration variables -- which is great unless you
already have a working configuration under the old model.

The most important changes regard the /location/ and /enabling/
of Babel (both core functionality and language specific support).

- Babel :: Babel is now part of the core of Org-mode, so it is
     now loaded along with the rest of Org-mode.  That means that
     there is /no configuration/ required to enable the main
     Babel functionality.  For current users, this means that
     statements like
     #+begin_src emacs-lisp
       (require 'org-babel)
     #+end_src
     or
     #+begin_src emacs-lisp
       (require 'org-babel-init)
     #+end_src
     that may by lying around in your configuration must now be
     removed.
- load path :: Babel (including all language specific files --
     aside from those which are located in the =contrib/=
     directory for reasons of licencing) now lives in the base of
     the Org-mode lisp directory, so /no additional directories/
     need to be added to your load path to use babel.  For Babel
     users this means that statements adding babel-specific
     directories to your load-path should now be removed from
     your config.
- language support :: It is no longer necessary to require
     language specific support on a language-by-language basis.
     Specific language support should now be managed through the
     `org-babel-load-languages' variable.  This variable can be
     customized using the Emacs customization interface, or
     through the addition of something like the following to your
     configuration (note: any language not mentioned will /not/
     be enabled, aside from =emacs-lisp= which is enabled by
     default)
     #+begin_src emacs-lisp
       (org-babel-do-load-languages
        'org-babel-load-languages
        '((R . t)
          (ditaa . t)
          (dot . t)
          (emacs-lisp . t)
          (gnuplot . t)
          (haskell . nil)
          (ocaml . nil)
          (python . t)
          (ruby . t)
          (screen . nil)
          (sh . t)
          (sql . nil)
          (sqlite . t)))
     #+end_src
     
	   Despite this change it is still possible to add
	   language support through the use of =require=
	   statements, however to conform to Emacs file-name
	   regulations all Babel language files have changed
	   prefix from =org-babel-*= to =ob-*=, so the require
	   lines must also change e.g.
	   #+begin_src emacs-lisp
       (require 'org-babel-R)
	   #+end_src
	   should be changed to
	   #+begin_src emacs-lisp
       (require 'ob-R)
	   #+end_src

We have eliminated the =org-babel-tangle-w-comments= variable as
well as the two main internal lists of languages, namely
- =org-babel-interpreters= and
- =org-babel-tangle-langs= 

so any config lines which mention those variables, can/should be
stripped out in their entirety.  This includes any calls to the
=org-babel-add-interpreter= function, whose sole purpose was to
add languages to the =org-babel-interpreters= variable.

With those calls stripped out, we may still in some cases want to
associate a file name extension with certain languages, for
example we want all of our emacs-lisp files to end in a =.el=, we
can do this will the =org-babel-tangle-lang-exts= variable.  In
general you shouldn't need to touch this as it already has
defaults for most common languages, and if a language is not
present in org-babel-tangle-langs, then babel will just use the
language name, so for example a file of =c= code will have a =.c=
extension by default, shell-scripts (identified with =sh=) will
have a =.sh= extension etc...

The configuration of /shebang/ lines now lives in header
arguments.  So the shebang for a single file can be set at the
code block level, e.g.

#+begin_src org
  ,#+begin_src clojure :shebang #!/usr/bin/env clj
  ,  (println "with a shebang line, I can be run as a script!")
  ,#+end_src  
#+end_src

Note that whenever a file is tangled which includes a /shebang/
line, Babel will make the file executable, so there is good
reason to only add /shebangs/ at the source-code block level.
However if you're sure that you want all of your code in some
language (say shell scripts) to tangle out with shebang lines,
then you can customize the default header arguments for that
language, e.g.

#+begin_src emacs-lisp
  ;; ensure this variable is defined defined
  (unless (boundp 'org-babel-default-header-args:sh)
    (setq org-babel-default-header-args:sh '()))
  
  ;; add a default shebang header argument
  (add-to-list 'org-babel-default-header-args:sh
               '(:shebang . "#!/bin/bash"))  
#+end_src

The final important change included in this release is the
addition of new security measures into Babel.  These measures are
in place to protect users from the accidental or uninformed
execution of code.  Along these lines /every/ execution of a code
block will now require an explicit confirmation from the user.
These confirmations can be stifled through customization of the
`org-confirm-babel-evaluate' variable, e.g.
#+begin_src emacs-lisp
  ;; I don't want to be prompted on every code block evaluation
  (setq org-confirm-babel-evaluate nil)
#+end_src

In addition, it is now possible to remove code block evaluation
form the =C-c C-c= keybinding.  This can be done by setting the
=org-babel-no-eval-on-ctrl-c-ctrl-c= variable to a non-nil value,
e.g.
#+begin_src emacs-lisp
  ;; I don't want to execute code blocks with C-c C-c
  (setq org-babel-no-eval-on-ctrl-c-ctrl-c t)
#+end_src

An additional keybinding has been added for code block
evaluation, namely =C-c C-v e=.

Whew! that seems like a lot of effort for a /simplification/ of
configuration.

*** New keys for TODO sparse trees

The key =C-c C-v= is now reserved for Org Babel action.  TODO
sparse trees can still be made with =C-c / t= (all not-done
states) and =C-c / T= (specific states).

*** Customizable variable changes for DocBook exporter

To make it more flexible for users to provide DocBook exporter
related commands, we start to use format-spec to format the
commands in this release.  If you use DocBook exporter and use it
to export Org files to PDF and/or FO format, the settings of the
following two customizable variables need to be changed:

- =org-export-docbook-xslt-proc-command=
- =org-export-docbook-xsl-fo-proc-command=

Instead of using =%s= in the format control string for all
arguments, now we use /three/ different format spec characters:

- =%i=: input file argument
- =%o=: output file argument
- =%s=: XSLT stylesheet argument

For example, if you set =org-export-docbook-xslt-proc-command= to

: java com.icl.saxon.StyleSheet -o %s %s /path/to/docbook.xsl

in the past, now you need to change it to

: java com.icl.saxon.StyleSheet -o %o %i %s

and set a new customizable variable called
=org-export-docbook-xslt-stylesheet= to =/path/to/docbook.xsl=.

Please check the documentation of these two variables for more
details and other examples.

Along with the introduction of variable
=org-export-docbook-xslt-stylesheet=, we also added a new
in-buffer setting called =#+XSLT:=.  You can use this setting to
specify the XSLT stylesheet that you want to use on a per-file
basis.  This setting overrides
=org-export-docbook-xslt-stylesheet=.

** Details

*** Org Babel is now part of the Org core
See [[#ob-configuration-changes][Org-babel configuration changes]] for instructions on how to
update your babel configuration.

The most significant result of this change is that Babel now has
documentation!  It is part of Org-mode's documentation, see
Chapter 14 [[http://orgmode.org/manual/Working-with-source-code.html#Working-with-source-code][Working With Source Code]].  The Babel keybindings
are now listed in the refcard, and can be viewed from any
Org-mode buffer by pressing =C-c C-v h=.  In addition this
integration has included a number of bug fixes, and a significant
amount of internal code cleanup.

*** The default capture system for Org mode is now called org-capture

This replaces the earlier system org-remember.  The manual only
describes org-capture, but for people who prefer to continue to
use org-remember, we keep a static copy of the former manual
section [[http://orgmode.org/org-remember.pdf][chapter about remember]].

The new system has a technically cleaner implementation and more
possibilities for capturing different types of data.  See
[[http://thread.gmane.org/gmane.emacs.orgmode/26441/focus%3D26441][Carsten's announcement]] for more details.

To switch over to the new system:

1. Run 

   : M-x org-capture-import-remember-templates RET

   to get a translated version of your remember templates into the
   new variable =org-capture-templates=.  This will "mostly" work,
   but maybe not for all cases.  At least it will give you a good
   place to modify your templates.  After running this command,
   enter the customize buffer for this variable with 

   : M-x customize-variable RET org-capture-templates RET

   and convince yourself that everything is OK.  Then save the
   customization.
   
2. Bind the command =org-capture= to a key, similar to what you did
   with org-remember:

   : (define-key global-map "\C-cc" 'org-capture)

   If your fingers prefer =C-c r=, you can also use this key once
   you have decided to move over completely to the new
   implementation.  During a test time, there is nothing wrong
   with using both system in parallel.

*** Implement pretty display of entities, sub-, and superscripts.

The command =C-c C-x \= toggles the display of Org's special
entities like =\alpha= as pretty unicode characters.  Also, sub
and superscripts are displayed in a pretty way (raised/lower
display, in a smaller font).  If you want to exclude sub- and
superscripts, see the variable
=org-pretty-entities-include-sub-superscripts=.

Thanks to Eric Schulte and Ulf Stegeman for making this possible.

*** Help system for finding entities

The new command =M-x org-entities-help= creates a structured
buffer that lists all entities available in Org.  Thanks to Ulf
Stegeman for adding the necessary structure to the internal
entity list.

*** New module to create Gantt charts

Christian Egli's /org-taskjuggler.el/ module is now part of Org.
He also wrote a [[http://orgmode.org/worg/org-tutorials/org-taskjuggler.php][tutorial]] for it.

*** Refile targets can now be cached

You can turn on caching of refile targets by setting the variable
=org-refile-use-cache=.  This should speed up refiling if you
have many eligible targets in many files.  If you need to update
the cache because Org misses a newly created entry or still
offers a deleted one, press =C-0 C-c C-w=.

*** Enhanced functionality of the clock resolver

Here are the new options for the clock resolver:
    
: i/q/C-g  Ignore this question; the same as keeping all the idle time.
: 
: k/K      Keep X minutes of the idle time (default is all).  If this
:          amount is less than the default, you will be clocked out
:          that many minutes after the time that idling began, and then
:          clocked back in at the present time.
: g/G      Indicate that you \"got back\" X minutes ago.  This is quite
:          different from 'k': it clocks you out from the beginning of
:          the idle period and clock you back in X minutes ago.
: s/S      Subtract the idle time from the current clock.  This is the
:          same as keeping 0 minutes.
: C        Cancel the open timer altogether.  It will be as though you
:          never clocked in.
: j/J      Jump to the current clock, to make manual adjustments.
    
For all these options, using uppercase makes your final state
to be CLOCKED OUT.  Thanks to John Wiegley for making these
changes.

*** A property value of "nil" now means to unset a property

This can be useful in particular with property inheritance, if
some upper level has the property, and some grandchild of it
would like to have the default settings (i.e. not overruled by a
property) back.

Thanks to Robert Goldman and Bernt Hansen for suggesting this
change.

*** The problem with comment syntax has finally been fixed

Thanks to Leo who has been on a year-long quest to get this fixed
and finally found the right way to do it.

*** Make it possible to protect hidden subtrees from being killed by =C-k=
    
This was a request by Scott Otterson.
See the new variable =org-ctrl-k-protect-subtree=.
    
*** New module org-mac-link-grabber.el

This module allows to grab links to all kinds of applications on
a mac.  It is available in the contrib directory.

Thanks to Anthony Lander for this contribution.

*** LaTeX export: Implement table* environment for wide tables
    
Thanks to Chris Gray for a patch to this effect.

*** When cloning entries, remove or renew ID property

Thanks to David Maus for this change.

* Version 6.36

 :PROPERTIES:
 :CUSTOM_ID: v6.36
 :END:

** Details
*** Inline display of linked images

Images can now be displayed inline.  The key C-c C-x C-v does
toggle the display of such images.  Note that only image links
that have no description part will be inlined.

*** Implement offsets for ordered lists

If you want to start an ordered plain list with a number
different from 1, you can now do it like this:
    
: 1. [@start:12] will star a lit a number 12

*** Extensions to storing and opening links to Wanderlust messages
    
- Remove filter conditions for messages in a filter folder
    
  If customization variable `org-wl-link-remove-filter' is non-nil,
  filter conditions are stripped of the folder name.
    
- Create web links for messages in a Shimbun folder

  If customization variable `org-wl-shimbun-prefer-web-links' is
  non-nil, calling `org-store-link' on a Shimbun message creates a
  web link to the messages source, indicated in the Xref: header
  field.

- Create web links for messages in a nntp folder

  If customization variable `org-wl-nntp-prefer-web-links' is
  non-nil, calling `org-store-link' on a nntp message creates a web
  link either to gmane.org if the group can be read trough gmane or
  to googlegroups otherwise. In both cases the message-id is used as
  reference.

- Open links in namazu search folder

  If `org-wl-open' is called with one prefix, WL opens a namazu
  search folder for message's message-id using
  `org-wl-namazu-default-index' as search index.  If this variable is
  nil or `org-wl-open' is called with two prefixes Org asks for the
  search index to use.

Thanks to David Maus for these changes.

*** Org-babel: code block body expansion for table and preview

In org-babel, code is "expanded" prior to evaluation. I.e. the
code that is actually evaluated comprises the code block
contents, augmented with the extra code which assigns the
referenced data to variables. It is now possible to preview
expanded contents, and also to expand code during during
tangling. This expansion takes into account all header arguments,
and variables.

A new key-binding C-c M-b p bound to
`org-babel-expand-src-block' can be used from inside of a
source code block to preview its expanded contents (which can
be very useful for debugging).  tangling

The expanded body can now be tangled, this includes variable
values which may be the results of other source-code blocks, or
stored in headline properties or tables. One possible use for
this is to allow those using org-babel for their emacs
initialization to store values (e.g. usernames, passwords,
etc…) in headline properties or in tables.

Org-babel now supports three new header arguments, and new
default behavior for handling horizontal lines in tables
(hlines), column names, and rownames across all languages.

** Incompatible Changes

*** Changes to the intended use of =org-export-latex-classes=

So far this variable has been used to specify the complete header
of the LaTeX document, including all the =\usepackage= calls
necessary for the document.  This setup makes it difficult to
maintain the list of packages that Org itself would like to call,
for example for the special symbol support it needs.  Each time I
have to add a package, I have to ask people to revise the
configuration of this variable.  In this release, I have tried to
fix this.

First of all, you can *opt out of this change* in the following
way: You can say: /I want to have full control over headers, and
I will take responsibility to include the packages Org needs/.
If that is what you want, add this to your configuration and skip
the rest of this section (except maybe for the description of the
=[EXTRA]= place holder):

#+begin_src emacs-lisp
  (setq org-export-latex-default-packages-alist nil
        org-export-latex-packages-alist nil)
#+end_src

/Continue to read here if you want to go along with the modified
setup./

There are now two variables that should be used to list the LaTeX
packages that need to be included in all classes.  The header
definition in =org-export-latex-classes= should then not contain
the corresponding =\usepackage= calls (see below).

The two new variables are:

1. =org-export-latex-default-packages-alist= :: This is the
     variable where Org-mode itself puts the packages it needs.
     Normally you should not change this variable.  The only
     reason to change it anyway is when one of these packages
     causes a conflict with another package you want to use.
     Then you can remove that packages and hope that you are not
     using Org-mode functionality that needs it.

2. =org-export-latex-packages-alist= :: This is the variable
     where you can put the packages that you'd like to use across
     all classes.  For example, I am putting =amsmath= and =tikz=
     here, because I always want to have them.

The sequence how these customizations will show up in the LaTeX
document are:
1. Header from =org-export-latex-classes=
2. =org-export-latex-default-packages-alist=
3. =org-export-latex-packages-alist=
4. Buffer-specific things set with =#+LaTeX_HEADER:=

If you want more control about which segment is placed where, or
if you want, for a specific class, have full control over the
header and exclude some of the automatic building blocks, you can
put the following macro-like place holders into the header:

#+begin_example
[DEFAULT-PACKAGES]      \usepackage statements for default packages
[NO-DEFAULT-PACKAGES]   do not include any of the default packages
[PACKAGES]              \usepackage statements for packages 
[NO-PACKAGES]           do not include the packages
[EXTRA]                 the stuff from #+LaTeX_HEADER
[NO-EXTRA]              do not include #+LaTeX_HEADER stuff
#+end_example

If you have currently customized =org-export-latex-classes=, you
should revise that customization and remove any package calls that
are covered by =org-export-latex-default-packages-alist=.  This
applies to the following packages:

- inputenc
- fontenc
- fixltx2e
- graphicx
- longtable
- float
- wrapfig
- soul
- t1enc
- textcomp
- marvosym
- wasysym
- latexsym
- amssymb
- hyperref

If one of these packages creates a conflict with another package
you are using, you can remove it from
=org-export-latex-default-packages-alist=.  But then you risk
that some of the advertised export features of Org will not work
properly.

You can also consider moving packages that you use in all classes
to =org-export-latex-packages-alist=.  If necessary, put the
place holders so that the packages get loaded in the right
sequence.  As said above, for backward compatibility, if you omit
the place holders, all the variables will dump their content at
the end of the header.

Damn, this has become more complex than I wanted it to be.  I
hope that in practice, this will not be complicated at all.

*** The constant =org-html-entities= is obsolete

Its content is now part of the new constant =org-entities=, which
is defined in the file org-entities.el.  =org-html-entities= was
an internal variable, but it is possible that some users did
write code using it - this is why I am mentioning it here.

** Editing Convenience and Appearance

*** New faces for title, date, author and email address lines.
    
The keywords in these lines are now dimmed out, and the title is
displayed in a larger font, and a special font is also used for
author, date, and email information.  This is implemented by the
following new faces:
    
org-document-title
org-document-info
org-document-info-keyword
    
In addition, the variable =org-hidden-keywords= can be used to
make the corresponding keywords disappear.

Thanks to Dan Davison for this feature.

*** Simpler way to specify faces for tags and todo keywords
    
The variables =org-todo-keyword-faces=, =org-tag-faces=, and
=org-priority-faces= now accept simple color names as
specifications.  The colors will be used as either foreground or
background color for the corresponding keyword.  See also the
variable =org-faces-easy-properties=, which governs which face
property is affected by this setting.

This is really a great simplification for setting keyword faces.
The change is based on an idea and patch by Ryan Thompson.

*** <N> in tables now means fixed width, not maximum width
    
Requested by Michael Brand.

*** Better level cycling function

=TAB= in an empty headline cycles the level of that headline
through likely states.  Ryan Thompson implemented an improved
version of this function, which does not depend upon when exactly
this command is used.  Thanks to Ryan for this improvement.

*** Adaptive filling
    
For paragraph text, =org-adaptive-fill-function= did not handle the
base case of regular text which needed to be filled.  This is now
fixed.  Among other things, it allows email-style ">" comments
to be filled correctly.

Thanks to Dan Hackney for this patch.    

*** `org-reveal' (=C-c C-r=) also decrypts encrypted entries (org-crypt.el)
    
Thanks to Richard Riley for triggering this change.

*** Better automatic letter selection for TODO keywords
    
When all first letters of keywords have been used, Org now assigns
more meaningful characters based on the keywords.

Thanks to Mikael Fornius for this patch.

** Export

*** Much better handling of entities for LaTeX export

Special entities like =\therefore= and =\alpha= now know if
they need to be in LaTeX math mode and are formatted accordingly.

Thanks to Ulf Stegemann for the tedious work to make this
possible.
    
*** LaTeX export: Set coding system automatically

The coding system of the LaTeX class will now be set to the value
corresponding to the buffer's file coding system.  This happens
if your setup sets up the file to have a line
=\usepackage[AUTO]{inputenc}= (the default setup does this).

*** New exporters to Latin-1 and UTF-8

While Ulf Stegemann was going through the entities list to
improve the LaTeX export, he had the great idea to provide
representations for many of the entities in Latin-1, and for all
of them in UTF-8.  This means that we can now export files rich
in special symbols to Latin-1 and to UTF-8 files.  These new
exporters can be reached with the commands =C-c C-e n= and =C-c
C-e u=, respectively.

When there is no representation for a given symbol in the
targeted coding system, you can choose to keep the TeX-macro-like
representation, or to get an "explanatory" representation.  For
example, =\simeq= could be represented as "[approx. equal to]".
Please use the variable =org-entities-ascii-explanatory= to state
your preference.

*** Full label/reference support in HTML, Docbook, and LaTeX backends

=#+LABEL= definitions for tables and figures are now fully
implemented in the LaTeX, Docbook, and HTML interfaces.
=\ref{xxx}= is expanded to a valid link in all backends.

*** BEAMER export: Title of the outline frame is now customizable
    
The new option =org-outline-frame-title= allows to set the 
title for outline frames in Beamer presentations.

Patch by Łukasz Stelmach.
    
*** BEAMER export: fragile frames are better recognized

A =lstlisting= environment now also triggers the fragile option in
a beamer frame, just like =verbatim= environments do.

Thanks to Eric Schulte for this patch.

*** BEAMER export: Protect <...> macro arguments

Macros for the BEAMER package can have arguments in angular
brackets.  These are now protected just like normal arguments.

Requested by Bill Jackson.

*** HTML export: Add class to outline containers using property
    
The =HTML_CONTAINER_CLASS= property can now be used to add a
class name to the outline container of a node in HTML export.

*** New option =org-export-email-info= to turn off export of the email address
    
Default is actually off now.

*** Throw an error when creating an image from a LaTeX snippet fails

This behavior can be configured with the new option variable
=org-format-latex-signal-error=.

** Index generation
    
Org-mode can now produce a 2-level subject index spanning an
entire publishing project.  Write index entries in your files as

#+begin_src org
,* What is org-mode?
#+index: Org-mode
#+index: Definitions!Org-mode
#+end_src

where the first line will produce an index entry /Org-mode/,
while the second line will create /Definitions/ with a sub-item
/Org-mode/.  Three-level entries are not supported.

To produce the index, set

#+begin_src emacs-lisp
:makeindex t
#+end_src

in the project definition in =org-publish-project-alist=.  You
may have to force re-export of all files to get the index by
using a =C-u= prefix to the publishing command:

#+begin_example
C-u M-x org-publish-all
#+end_example

Whenever an Org file is published in this project, a new file
with the extension "orgx" will be written.  It contains the index
entries and corresponding jump target names.  When all project
files are published, Org will produce a new file "theindex.inc"
containing the index as a to-level tree.  This file can be
included into any project file using

#+begin_src org
  ,#+include: "theindex.inc"
#+end_src

Org-mode will also create a file "theindex.org" with this include
statement, and you can build a more complex structure (for
example style definitions, top and home links, etc) around this
statement.  When this file already exists, it will not be
overwritten by Org.

Thanks to Stefan Vollmar for initiating and driving this feature.

*** TODO Still need to do the LaTeX portion

** MobileOrg

*** Encrypting stage files for MobileOrg

Since the use of (often pubic) servers is needed for MobileOrg,
it is now possible to encrypt the files to be staged for
MobileOrg.  Version 1.2 of MobileOrg will be needed for this
feature, and Richard Moreland will show instructions on his
website once that is available.  Basically, on the Org-side this
will require the following settings:

#+begin_src emacs-lisp
  (setq org-mobile-use-encryption t
        org-mobile-encryption-password "My_MobileOrg_Password")
#+end_src

So the password will be visible in your local setup, but since
the encryption is only for the public server, this seems
acceptable.

** Agenda

*** Specify entry types as an option
    
Custom Agenda commands can now limit the sets of entry types
considered for this command by binding =org-agenda-entry-types=
temporarily in the options section of the command.  This can lead
to significant speedups, because instead of laboriously finding
entries and then rejecting them, a whole search cycle is skipped.
For more information see the new section in
[[http://orgmode.org/worg/org-tutorials/org-custom-agenda-commands.php#sec-5][Matt Lundin's agenda custom command tutorial]].

Thanks to Matt Lundin for this feature.

*** Speed up multiple calls to org-diary by only doing buffer prep once
    
Also a patch by Matt Lundin.

*** Show and hide deadlines in the agenda

You can now hide all deadline entries in the agenda by pressing
=!=.

Thanks to John Wiegley for this feature.

*** Agenda: Allow to suppress deadline warnings for entries also scheduled

The the docstring of the variable
=org-agenda-skip-deadline-prewarning-if-scheduled=.

*** Expand file names in org-agenda-files (external file case)
    
If you are using a file to manage the list of agenda files, the
names in this file can now contain environment variables and "~"
to write them more compactly and portable.

Thanks to Mikael Fornius for a patch to this effect.

*** Agenda: Allow TODO conditions in the skip functions

The agenda skip function has now special support for skipping
based on the TODO state.  Here are just two examples, see the
manual for more information.

#+begin_src emacs-lisp
(org-agenda-skip-entry-if 'todo '(\"TODO\" \"WAITING\"))
(org-agenda-skip-entry-if 'nottodo 'done)
#+end_src

Thanks to Łukasz Stelmach for this patch.

*** Extracting the time-of-day when adding diary entries

The time of day can now be extracted from new diary entries made
from the agenda with (for example) =i d=.  When
=org-agenda-insert-diary-extract-time= is set, this is done, and
the time is moved into the time stamp.

Thanks to Stephen Eglen for this feature.

*** The customization group org-font-lock has been renamed

The new name is `org-appearance'.

Thanks to Dan Davison for a patch to this effect.

*** The TODO list: Allow skipping scheduled or deadlined entries

Skipping TODO entries in the global TODO list based on whether
they are scheduled or have a deadline can now be controlled in
more detail.  Please see the docstrings of
=org-agenda-todo-ignore-scheduled= and
=org-agenda-todo-ignore-deadline=.

Thanks to Łukasz Stelmach for patches to this effect.

** Hyperlinks

*** Make =org-store-link= point to directory in a dired buffer
    
When, in a dired buffer, the cursor is not in a line listing a
file, `org-store-link' will store a link to the directory.

Patch by Stephen Eglen.

*** Allow regexps in =org-file-apps= to capture link parameters
    
The way extension regexps in =org-file-apps= are handled has
changed.  Instead of matching against the file name, the regexps
are now matched against the whole link, and you can use grouping
to extract link parameters which you can then use in a command
string to be executed.

For example, to allow linking to PDF files using the syntax
=file:/doc.pdf::<page number>=, you can add the following entry to
org-file-apps:

#+begin_example
Extension: \.pdf::\([0-9]+\)\'
Command:   evince "%s" -p %1
#+end_example

Thanks to Jan Böcker for a patch to this effect.

** Clocking

*** Show clock overruns in mode line

When clocking an item with a planned effort, overrunning the
planned time is now made visible in the mode line, for example
using the new face =org-mode-line-clock-overrun=, or by adding an
extra string given by =org-task-overrun-text=.

Thanks to Richard Riley for a patch to this effect.

** Tables

*** Repair the broken support for table.el tables again.
    
Tables created with the table.el package now finally work again
in Org-mode.  While you cannot edit the table directly in the
buffer, you can use  =C-c '= to edit it nicely in a temporary
buffer.

Export of these tables to HTML seem to work without problems.
Export to LaTeX is imperfect.  If fails if the table contains
special characters that will be replaced by the exporter before
formatting the table.  The replacement operation changes the
length of some lines, breaking the alignment of the table fields.
Unfortunately this is not easy to fix.  It is also not an option
to not do these replacements.  The table.el LaTeX exporter will
for example not escape "&" in table fields, causing the exported
tables to be broken.

** Misc

*** New logging support for refiling

Whenever you refile an item, a time stamp and even a note can be
added to this entry.  For details, see the new option
=org-log-refile=.
    
Thanks to Charles Cave for this idea.

*** New helper functions in org-table.el

There are new functions to access and write to a specific table
field.  This is for hackers, and maybe for the org-babel people.

#+begin_example
org-table-get
org-table-put
org-table-current-line
org-table-goto-line
#+end_example

*** Tables: Field coordinates for formulas, and improved docs
    
Calc and Emacs-Lisp formulas for tables can access the current
field coordinates with =@#= and =$#= for row and column,
respectively.  These can be useful in some formulas.  For
example, to sequentially number the fields in a column, use
~=@#~ as column equation.

One application is to copy a column from a different table.  See
the manual for details.

Thanks to Michael Brand for this feature.

*** Archiving: Allow to reverse order in target node
    
The new option =org-archive-reversed-order= allows to have
archived entries inserted in a last-on-top fashion in the target
node.
    
Requested by Tom.

*** Better documentation on calc accuracy in tables
    
Thanks to Michael Brand for this fix.

*** Clock reports can now include the running, incomplete clock

If you have a clock running, and the entry being clocked falls
into the scope when creating a clock table, the time so far spent
can be added to the total.  This behavior depends on the setting
of =org-clock-report-include-clocking-task=.  The default is
=nil=.
    
Thanks to Bernt Hansen for this useful addition.

*** American-style dates are now understood by =org-read-date=

So when you are prompted for a date, you can now answer like this

#+begin_example
2/5/3         --> 2003-02-05
2/5           --> <CURRENT-YEAR>-02-05
#+end_example    

*** org-timer.el now allows just one timer

There is now only a single free timer supported by org-timer.el.
Thanks to Bastien for cleaning this up, after a bug report in
this area by Frédéric Couchet.

*** Remember: Allow to file as sibling of current clock
    
=C-3 C-c C-c= will file the remember entry as a sibling of the
last filed entry.

Patch by Łukasz Stelmach.

*** Org-reveal: Double prefix arg shows the entire subtree of the parent
    
This can help to get out of an inconsistent state produced for
example by viewing from the agenda.

This was a request by Matt Lundin.

*** Add org-secretary.el by Juan Reyero to the contrib directory

org-secretary.el is a possible setup for group work using
Org-mode.

Thanks to Juan Reyero for this contribution.

** Babel

Eric and Dan have compiled the following list of changes in and
around org-babel.

- Added support for Matlab and Octave.
- Added support for C and C++ code blocks.
- Added support for the Oz programming language.
  Thanks to Torsten Anders for this contribution
- Can now force literal interpretation of table cell contents
  with extra "$" in table formula.
  Thanks to Maurizio Vitale for this suggestion.
- Variable references which look like lisp forms are now
  evaluated.
- No longer adding extension during tangling when filename is
  provided.
  Thanks to Martin G. Skjæveland and Nicolas Girard for prompting this.
- Added `org-babel-execute-hook' which runs after code block
  execution.
- Working directories and remote execution

  This introduces a new header argument :dir. For the duration of
  source block execution, default-directory is set to the value
  of this header argument. Consequences include:

  - external interpreter processes run in that directory
  - new session processes run in that directory (but existing
    ones are unaffected)
  - relative paths for file output are relative to that directory

  The name of a directory on a remote machine may be specified
  with tramp syntax (/user@host:path), in which case the
  interpreter executable will be sought in tramp-remote-path, and
  if found will execute on the remote machine in the specified
  remote directory.
- Tramp syntax can be used to tangle to remote files.
  Thanks to Maurizio Vitale and Rémi Vanicat.
- org-R removed from contrib.
- gnuplot can now return it's string output -- when session is
  set to "none".
- Now including source code block arguments w/source name on
  export.
- Now able to reference file links as results.
- Allow pdf/png generation directly from latex source blocks
  with :file header argument.

* Version 6.34

** Incompatible changes

*** Tags in org-agenda-auto-exclude-function must be lower case.

When defining an =org-agenda-auto-exclude-function=, you need to
be aware that tag that is being passed into the function is
always lower case - even if it was defined in upper case
originally.

** Details

*** Support for creating BEAMER presentations from Org-mode documents

Org-mode documents or subtrees can now be converted directly in
to BEAMER presentation.  Turning a tree into a simple
presentations is straight forward, and there is also quite some
support to make richer presentations as well.  See the [[http://orgmode.org/manual/Beamer-class-export.html#Beamer-class-export][BEAMER
section]] in the manual for more details.

Thanks to everyone who has contributed to the discussion about
BEAMER support and how it should work.  This was a great example
for how this community can achieve a much better result than any
individual could.

*** Hyperlinks

**** Add Paul Sexton's org-ctags.el

Targets like =<<my target>>= can now be found by Emacs' etag
functionality, and Org-mode links can be used to to link to
etags, also in non-Org-mode files.  For details, see the file
/org-ctags.el/.

This feature uses a new hook =org-open-link-functions= which will
call function to do something special with text links.

Thanks to Paul Sexton for this contribution.

**** Add Jan Böcker's org-docview.el

This new module allows links to various file types using docview,
where Emacs displays images of document pages.  Docview link
types can point to a specific page in a document, for example to
page 131 of the Org-mode manual:

: [[docview:~/.elisp/org/doc/org.pdf::131][Org-Mode Manual]]

Thanks to Jan Böcker for this contribution.
    
**** New link types that force special ways of opening the file
    
- =file+sys:/path/to/file=  will use the system to open the file,
  like double-clicking would.
- file+emacs:/path/to/file will force opening the linked file
  with Emacs.

This was a request by John Wiegley.

**** Open all links in a node

When using =C-c C-o= on a headline to get a list of links in the
entry, pressing =RET= will open *all* links.  This allows
something like projects to be defined, with a number of files
that have to be opened by different applications.

This was a request by John Wiegley.

*** Agenda Views

**** Improve the logic of the search view.

The logic of search views is changed a bit.  See the docstring of
the function =or-search-view=.

These changes resulted from a discussion with Matt Lundin.

**** New face for entries from the Emacs diary

Entries that enter the Agenda through the Emacs diary now get the
face =org-agenda-diary=.

This was a request by Thierry Volpiatto.

**** New function `org-diary-class' to schedule classes with skipped weeks.

This was a request by Daniel Martins.

**** Empty matcher means prompt in agenda custom commands
    
When an agenda custom command has an empty string as MATCH
element, so far this would lead to a meaningless search using an
empty matcher.  Now an empty (or white) string will be
interpreted just like a nil matcher, i.e. the user will be
prompted for the match.

**** Agenda: Selectively remove some tags from agenda display

If you use tags very extensively, you might want to exclude some
from being displayed in the agenda, in order to keep the display
compact.  See the new option =org-agenda-hide-tags-regexp= for
details.
    
This was largely a patch by Martin Pohlack.

*** Export

**** Direct export of only the current subtree

Pressing =1= after =C-c C-e= and before the key that selects the
export backend, only the current subtree will be exported,
exactly as it you had selected it first with =C-c @=.  So for
example, =C-c C-e 1 b= will export the current subtree to HTML
and open the result in the browser.

**** Direct export of enclosing node

Pressing =SPC= after =C-c C-e= and before the key that selects
the export backend, the enclosing subree that is set up for
subtree export will be exported, exactly as it you had selected
it first with =C-c @=.  So for example, =C-c C-e SPC d= will find
the enclosing node with a LaTeX_CLASS property or an
EXPORT_FILE_NAME property and export that.

**** Caching export images

Images that are created for example using LaTeX or ditaa for
inclusion into exported files are now cached.  This works by
adding a hash to the image name, that reflects the source code
and all relevant settings.  So as long as the hash does not
change, the image does not have to be made again.  His can lead
to a substantial reduction in export/publishing times.

Thanks to Eric Schulte for a patch to this effect.

**** Preserving line breaks for export no longer works
    
ASCII export always preserves them - no other export format
does.  We had attempted to use =\obeylines= for this in LaTeX,
but that does create too many problems.

**** New symbols =\EUR= and =\checkmark=

=\EUR= symbols from Marvosym package, and =\checkmark= are now
supported symbols in Org-mode, i.e. they will be exported
properly to the various backends.

**** Allow LaTeX_CLASS_OPTIONS to set options, also from a property

You can set the options to the =\documentclass= command on a
per-file basis, using

: #+LaTeX_CLASS_OPTIONS: [11pt]

or on a per-tree basis using the corresponding property.  The
defined string will replace the default options entirely.

**** The encoding of LaTeX files is now handled property

Org now makes sure that the encoding used by the file created
through the export mechanism is reflected correctly in the

: \usepackage[CODINGSYSTEM]{inputenc}

command.  So as long as the =org-export-latex-classes= definition
contains an =\usepackage[utf8]{inputenc}= statement, that
statement will be modified so that the correct option is used.

If you wan to use special encodings, for example =utf8x= instead
of =utf8=, see the variable =org-export-latex-inputenc-alist=.

This was a request by Francesco Pizzolante.

*** Property API enhancements
    
**** Make a new special property BLOCKED, indicating if entry is blocked

A new special property BLOCKED returns "t" when the entry is
blocked from switching the TODO state to a DONE state.

This was a request by John Wiegley.

**** New hooks for external support for allowed property values

It is now possible to hook into Org in order to provide the
allowed values for any property with a lisp function.  See the
docstring of the variable =org-property-allowed-value-functions=

**** Allow unrestricted completion on properties

When listing the allowed values for a property, for example with
a =:name_ALL:= property, completion on these values enforces that
one of the values will be chosen.  Now, if you add ":ETC" to the
list of allowed values, it will be interpreted as a switch, and
the completion will be non-restrictive, so you can also choose to
type a new value.

*** Changes to Org-babel

- The documentation for Org-babel has been drastically improved
  and is available on Worg at
  http://orgmode.org/worg/org-contrib/babel/
- Source-code block names are now exported to HTML and LaTeX
- Org-babel functions are now bound to keys behind a common key
  prefix (see
  http://orgmode.org/worg/org-contrib/babel/reference.php#sec-5)
- Results are now foldable with TAB
- Header argument values can now be lisp forms
- Readable aliases for #+srcname: and #+resname:
- Sha1 hash based caching of results in buffer
- Can now index into variable values
- org-babel-clojure now supports multiple named sessions

*** Miscellaneous changes

**** Make =C-c r C= customize remember templates

=C-c r C= is now a shortcut for

:  M-x customize-variable RET org-remember-templates RET

This was a proposal by Adam Spiers.

**** Use John Gruber's regular expression for URL's

We now use a better regexp to spot plain links in text.  This
regexp is adopted from [[http://daringfireball.net/2009/11/liberal_regex_for_matching_urls][John Gruber's blogpost]].

Thanks to William Henney for the pointer.

**** Implement tag completion of all tags in all agenda files
    
The new option =org-complete-tags-always-offer-all-agenda-tags=
makes Org complete all tags from all agenda files if non-nil.
Usually, setting it locally to t in org-remember buffers is the
most useful application of this new feature.

Thanks to Tassilo Horn for a patch to this effect.

* Version 6.33
 :PROPERTIES:
 :CUSTOM_ID: v6.33
 :END:

** Incompatible changes

*** Reorganize key bindings for archiving
    
The following keys now do archiving

- C-c C-x C-a :: archive using the command specified in
     =org-archive-default-command=.  This variable is by default
     set to =org-archive-subtree=, which means arching to the
     archive file.
    
The three specific archiving commands are available through

- C-c C-x C-s ::    archive to archive file
- C-c C-x a ::     toggle the archive tag
- C-c C-x A ::   move to archive sibling

These bindings work the same in an Org file, and in the agenda.

In addition:
    
- In the agenda you can also use =a= to call the default archiving
  command, but you need to confirm the command with =y= so that this
  cannot easily happen by accident.
  
- For backward compatibility, =C-c $= in an org-mode file, and
  =$= in the agenda buffer continue to archive to archive file.


** Details

*** Level indentation cycling new empty entries and plain list items
:PROPERTIES:
:ID: 1CBF16C9-031C-4A03-A5EE-09B6AAB6209C
:END:

To speed up data entry, TAB now behaves special in an empty
headline, i.e. if the current line only contains the headline
starter stars, maybe a TOD keyword, but no further content.  This
is usually the situation just after creating a new headline with
=M-RET= or =M-S-RET=.

Then, TAB will first make the current entry a child of the
entry above, then a parent, then a grand parent etc until it
reaches top level.  Yet another TAB and you will be back at the
initial level at which the headline was created.

New plain list items behave in just the same way.

Sounds strange?  Try it, it is insanely fast when entering data.
If you still don't like it, turn it off by customizing
=org-cycle-level-after-item/entry-creation=.

Thanks to [[http://thread.gmane.org/gmane.emacs.orgmode/18236][Samuel Wales]] and [[http://thread.gmane.org/gmane.emacs.orgmode/18447/focus%3D19015][John Wiegley]] for ideas that
contributed to this new feature.

*** Speed commands at the start of a headline

If you set the variable =org-use-speed-commands=, the cursor
position at the beginning of a headline (i.e. before the first
star) becomes special.  Single keys execute special commands in
this place, for example outline navigation with =f=, =b=, =n=,
and =p=, equivalent to the corresponding =C-c C-f=, =C-c C-b=,
=C-c C-n=, and =C-c C-f= commands.  The full list of commands can
be seen by pressing =?= at the special location.  More commands
can be added and existing ones modified by configuring the
variable =org-speed-commands-user=.

This was a request by John Wiegley, based on similar speed
navigation in /allout.el/.

*** Logging changes in scheduling and deadline time stamps

Setting the variables =org-log-reschedule= and
=org-log-redeadline= to either =time= or =note= will arrange for
recording a logbook entry whenever a scheduling date or deadline
is changed.

This was a request by Rick Moynihan.

*** File remember notes into a date tree

Remember notes can now be filed to a location in a date tree.  A
date tree is an outline tree with years as top levels, months as
level 2 headings, and days as level three headings.  These are
great for journals and for recording appointments and other loose
dates because it will be easy to find all entries referencing a
particular date, and it will be easy to archive all such entry
from last year, for example.

To select date tree filing, set the HEADLINE part of the remember
template to the symbol =date-tree=.  The date tree will be build
in the file on top level.  However, if the file contains an entry
with a non-nil =DATE_TREE= property, then the tree will be build
under that headline.

*** New commands to create entries from agenda and calendar

If you make the variable =org-agenda-diary-file= point to an
org-mode file, the =i= key in both the agenda buffer and in the
Emacs calendar will be made to insert entries into that Org file.
The dates at the cursor and the mark are being used when making
entries for specific dates or blocks.  In the new file,
anniversaries will be collected under a special headline, and
day/block entries will be filed into a date tree (see previous
section).

This was a request by Stephen Eglen.

*** A new freemind exporter has been integrated with Org-mode

org-freemind.el has a number of entry points (for details, see
the source code), but you can also use Org's =C-c C-e m= to
export a file or a selected subtree.

Thanks to Lennart Borgman for this contribution.  An earlier
version of this file was part of the nxhtml package, under the
name /freemind.el/.

*** Drawers are now exported properly

Drawers are now exported when the configuration requires it,
i.e. if the variable `org-export-with-drawers' is t or a list
containing the drawers to export.

*** Min/Max/Mean age operators in Column View.
    
This lets you see how much time has passed since the specified
timestamp property each entry. The three operators (=@min=,
=@max=, =@mean=) show either the age of the youngest or oldest
entry or the average age of the children.

Thanks to James TD Smith for a patch to this effect.
    
*** Allow source code block indentation to be preserved
    
If =org-src-preserve-indentation= is non-nil, or if a block has a
=-i= switch, then the behavior of org-exp-blocks is altered as
follows:

1. Indentation is not removed before passing the block contents
   to the block-transforming plugin.
   
2. The result returned by the plugin is not re-indented.

3. Editing the source code block with =C-c '= preserves it's
   indentation.

Thanks to Dan Davison for this feature.

*** Frame/window control when switching to source code edit buffer.
    
When switching to a source code editing buffer with =C-c '=, you
can now control the frame / window setup using the new variable
=org-src-window-setup=.

Thanks to Dan Davison for this feature.

*** Refile an entry to the current clock

You can now quickly refile an entry to become a child of the
entry currently being clocked.  The keys for doing this are
=C-2 C-c C-w=.

This was a request by Bernt Hansen.

*** Make =C-c C-o= open the attachment directory is there are no links

If there is no link in an entry, =C-c C-o= will now open the
attachment directory instead.

This was a request/patch by John Wiegley.

*** org-mac-iCal.el: work with calendar "groups"
    
Some calendar systems (Google, Zimbra) handle subscriptions to
multiple calendars (or to an account) by grouping them under a
single caldav directory in the calendar tree.  org-mac-iCal used
to assumes there is only one ics file created per caldav
directory, so while it *creates* all of the needed merged ics
files, it only copies one of them to ~/Library/Calendar before
importing the contents into the diary.

Thanks to Doug Hellmann for a patch to fix this.

*** New module /org-learn.el/ in the contrib directory

The file implements the learning algorithm described at
http://supermemo.com/english/ol/sm5.htm, which is a system for reading
material according to "spaced repetition".  See
http://en.wikipedia.org/wiki/Spaced_repetition for more details.

Thanks to John Wiegley for this contribution.

*** New contributed package /org-git-link.el/

/org-git-link.el/ defines two new link types. The =git= link type
is meant to be used in the typical scenario and mimics the =file=
link syntax as closely as possible.  The =gitbare= link type
exists mostly for debugging reasons, but also allows e.g.
linking to files in a bare git repository for the experts.

Thanks to Raimar Finken for this contribution.

*** /org-annotation-helper.el/ and /org-browser-url.e./ have been removed
Please switch to /org-protocol.el/, into which contains the same
functionality in a more general framework.
*** The contributed /org-export-freemind/ package has been removed.
Org now contains a new freemind exporter, /org-freemind.el/.

** Org-babel Changes
- Clojure is supported [Thanks to Joel Boehland]
- Perl is supported
- Ruby and Python now respond to the :file header argument
- Added :results_switches header argument for passing switches
  through to raw src blocks
- Preserve indentation in source blocks on export and tangle
- Possible to evaluate noweb reference on tangling or code block
  evaluation
- Allowing multiple noweb references on a single line
- Cleaned up the passing of parameter values from Org-babel to
  language specific functions

* Version 6.32
 :PROPERTIES:
 :CUSTOM_ID: v6.32
 :END:

** Rewrite of org-mobile.org, for MobileOrg 1.0 (build 20)

MobileOrg is currently under review at the iPhone App Store.  You
will need Org-mode version 6.32 to interact with it.

** Added support for habit consistency tracking
    
/org-habit.el/ contains new code to track habits.  Please
configure the variable org-modules to activate it.  When active,
habits (a special TODO entry) will be displayed in the agenda
together with a "consistency graph".  Habit tracking is described
in a new [[http://orgmode.org/manual/Tracking-your-habits.html][manual section]].

Thanks to John Wiegley for this contribution.
    
** New context-aware tag auto-exclusion 

After writing a function relating to location and context
information, you will be able to press =/ RET= in the agenda to
exclude tasks that cannot be done in the current context. 
For details, see the information about filtering in the manual.

Thanks to John Wiegley for a patch to this effect.

** New clock resolving tools

When clocking into a new task while no clock is running, Org now
checks for orphaned CLOCK lines and offers to repair these before
starting the clock.  You can also configure this feature to check
for idle time and prompt you to subtract that time from the
running timer.
    
See the new [[http://orgmode.org/manual/Resolving-idle-time.html][manual section]] for more details.
    
Thanks to John Wiegley for a patch to this effect.

** Mutually exclusive tag groups can now have a name in the tags interface

The customize interface allows to optionally add a string to the
beginning or end of such a group.
    
Thanks to James TD Smith for a patch to this effect.

** Agenda Search view: Search for substrings
    
The default in search view (/C-c a s/)is now that the search
expression is searched for as a /substring/, i.e. the different
words must occur in direct sequence, and it may be only part of
a word.  If you want to look for a number of separate keywords
with Boolean logic, all words must be preceded by =+= or =-=.

This was, more-or-less, requested by John Wiegley.

** Make space and backspace scroll the show window in the agenda

Pressing SPC again after using it to show an agenda item in
another window will make the entire subtree visible, and show
scroll it.  Backspace and DEL will scroll back.

This was a request by Eric Fraga.
    
** File tags are now offered for completion during a tag prompts

Requested by Matt Lundin.

** Make `- SPC' an agenda filter that selects entries without any tags
    
Request by John Wiegley.

** Better way to edit multi-line macro definitions

The editing tool key =C-c '= now also edits =#+MACRO=
definitions, including multiline macros.

** Restructured Manual

The manual has been slightly reorganized.  The archiving stuff,
which was - somewhat obscurely - hidden in the /Document
Structure/ chapter, has been moved into the new chapter
/Capture-Refile-Archive/.  Also, there is a new chapter /Markup/
which contains both the markup rules (moved there from the Export
chapter) and the documentation for embedded LaTeX.

** Improved figure placement in LaTeX and HTML export
    
Text can now be wrapped around figures.  See the manual for
details.

** Allow date to be shifted into the future if time given is earlier than now
    
By setting

:     (setq org-read-date-prefer-future 'time)

you indicate to Org that, if you only give a time at the
date/time prompt, and if this time is earlier then the current
time, then the date of tomorrow will be assumed to be valid for
this event.  A similar mechanism was already in place for dates,
but now you can make it work for times as well.

** Collected changes in org-babel
- Source blocks can now reference source-blocks in other files
  using =filepath:srcname= syntax.
- Inline code blocks like =src_python{2+2}= are now exported
- Remote source block calls using the =#+lob: srcname(arg=val)=
  syntax can now be exported.
- When =:file= is supplied with an =R= block, graphics are
  automatically sent to file and linked from the org buffer, thus
  appearing on export.  The image format is obtained from the
  filename extension.  Possible values are =.png, .jpg, .jpeg,
  .tiff, .bmp, .pdf, .ps, .postscript=, defaulting to =png=.
- Results can be returned as parseable code using =:results code=,
  and as pretty-printed code using =:results pp= (emacs-lisp,
  python, ruby).  Thanks to Benny Andresen for the idea and patch
  for emacs-lisp.
- When =:file filename= is supplied, =:exports file= is unnecessary
- Header args are taken from org-file-properties in addition to
  properties active in the subtree.
- =:noweb= header argument now expands noweb references before
  source-block evaluation.
- Tangling honours the new org variable
  org-src-preserve-indentation, so that correct code is output for
  a language like python that depends on indentation.

** Changes in org-exp-blocks.el
- Interblocks export has been simplified.
- Support for R code (=begin_R= blocks and inline =\R{}=) has been
  removed.  Please use org-babel instead.

* Version 6.31
 :PROPERTIES:
 :CUSTOM_ID: v6.31
 :END:

** Org-babel is now part of the Org distribution

Org-babel provides the ability to execute source code in many
different languages within org-mode documents.  The results of
code execution -- text, tables and graphics -- can be integrated
into Org-mode documents and can be automatically updated during
publishing.  Since Org-babel allows execution of arbitrary code,
the range of tasks that can be addressed from within an Org mode
file becomes very large.  Examples of ways in which Org-babel
might be used include

- Documenting a task that involves some programming so that it is
  automatically repeatable
- Creating dynamic (executable) reports that respond to changes
  in the underlying data (Reproducible Research)
- Exportation of code contained in an Org-mode document into
  regular source code files (Literate Programming)

Additionally, Org-babel provides a programming environment within
Org files, in which data can be transmitted between parameterised
source code blocks in different languages, as well as between
source code blocks and Org-mode tables.

A simple API is defined so that users can add support for new
"languages" (broadly construed).  Languages currently supported
are:

- asymptote
- css
- ditaa
- dot
- emacs-lisp
- gnuplot
- haskell
- ocaml
- python
- R
- ruby
- sass
- sh
- sql

Org-babel was designed and implemented Eric Schulte with continued
significant help on both accounts from Dan Davison.

** MobileOrg support

Richard Morelands iPhone/iPod Touch program [[http://mobileorg.ncogni.to/][MobileOrg]] can view
Org files, mark entries as DONE, flag entries for later
attention, and capture new entries on the road.  Org-mode has now
support to produce a staging area where MobileOrg can download
its files, and to integrate changes done on the phone in a half
automatic, half interactive way.  See the new appendix B in the
manual for more information.


** Indented lines starting with "#+ " are treated as comments

To allow comments in plain lists without breaking the list
structure, you can now have indented comment lines that start
with "#+ ".

** New STARTUP keyword `showeverything'
    
This will make even drawer contents visible upon startup.
Requested by Jeff Kowalczyk.

** New contributed package org-invoice.el

This package collects clocking information for billing
customers.

Thanks to Peter Jones for this contribution.

** Encrypting subtrees

/org-crypt.el/ by John Wiegley and Peter Jones allows encryption
of individual subtrees in Org-mode outlines.  Thanks to John and
Peter for this contribution.

** Agenda: Support for including a link in the category string
    
The category (as specified by an #+CATEGORY line or CATEGORY
property can contain a bracket link.  While this sort-of worked
in the past, it now is officially supported and should cause no
problems in agenda display or update.  The link can be followed
by clicking on it, or with =C-c C-o 0=.

This was a request by Peter Westlake.

** Inconsistent changes

*** Agenda now uses =f= and =b= to move through time

Up to now, the Org-mode agenda used the cursor keys =left= and
=right= to switch the agenda view forward an backward through
time.  However, many people found this confusing, and others
wanted to be able to do cursor motion in the agenda, for example
to select text.  Therefore, after an extensive discussion on
=emacs-orgmode@gnu.org=, it was decided to use the =b= and 
=f= keys instead, and to let the cursor keys do cursor motion
again.

*** Agenda follow mode is now on the =F= key

This was necessary to free up the =f= key, see above.

** Details

*** Maintenance

**** New command to submit a bug report

There is now a special command =M-x org-submit-bug-report=.  This
command will create a mail buffer with lots of useful details.
In particular, it contains complete version information for Emacs
and Org-mode.  It will also (if you agree to it) contain all
non-standard settings of org-mode and outline-mode related
variables.  Even if you do not sent your emails from within
Emacs, please still use this command to generate the information
and then copy it into your mail program.

The command will not generate and include a =*Backtrace*= buffer,
please do this yourself if you have hit an error.  For more
information, see the [[http://orgmode.org/manual/Feedback.html#Feedback][feedback section]] of the manual.

**** New contributed package org-track.el

This package allows to keep up-to-date with current Org
development, using only Emacs on-board means.  So if you don't
want or cannot use =git=, but still want to run the latest and
hottest Org-mode, this is for you.

Thanks to Sebastian Rose for this contribution.

*** Agenda

**** Agenda now uses =f= and =b= to move through time

Up to now, the Org-mode agenda used the cursor keys =left= and
=right= to switch the agenda view forward an backward through
time.  However, many people found this confusing, and others
wanted to be able to do cursor motion in the agenda, for example
to select text.  Therefore, after an extensive discussion on
=emacs-orgmode@gnu.org=, it was decided to use the =b= and 
=f= keys instead, and to let the cursor keys do cursor motion
again.

**** Agenda follow mode is now on the =F= key

This was necessary to free up the =f= key, see above.

**** The agenda can be put into a dedicated frame

When the variable =org-agenda-window-setup= has the value
=other-frame=, then the new frame created to show the agenda
will now have the window marked as /dedicated/.  As a
consequence, exiting the agenda while the agenda is the only
window on the frame will kill that frame.

This was a request by Henry Atting.

**** New mode to show some entry body text in the agenda

There is now a new agenda sub-mode called
=org-agenda-entry-text-mode=.  It is toggled with the =E= key.
When active, all entries in the agenda will be accompanied by a
few lines from the outline entry.  The amount of text can be
customized with the variable =org-agenda-entry-text-maxlines=.

This was a request by Anthony Fairchild, Manish, and others.

**** Improve following links from the agenda
    
=C-c C-o= in the agenda will now offer all links in the headline
and text of an entry.  If there is only a single link, it will be
followed immediately.

**** Avoid some duplicate entries

There is a new variable that can be used to avoid some duplicate
agenda entries: =org-agenda-skip-scheduled-if-deadline-is-shown=
If that is set, it avoids that an entry shows up in the agenda for
today for both a scheduling and a deadline entry.  See the
docstring of the variables for more details.

This partially addresses a request by Samuel Wales. 

**** Mark the running clock in the agenda.

If the entry currently being clocked is present in the agenda, it
will be highlighted with the face =org-agenda-clocking=.

This was a request by Rainer Stengele.


*** Export

**** Allow LaTeX export to use the listings package

The LaTeX =listings= package can now be used for formatting
fontified source code in many programming languages.  For more
information, see
http://thread.gmane.org/gmane.emacs.orgmode/16269 and
http://orgmode.org/worg/org-faq.php#fontified_source_code_w_latex

Thanks to Eric Schulte for this patch.

**** Remove table rows that only contain width and alignment markers
    
The width and alignment in table columns can be set with a cookie
like "<10>" or "<r>" or "<r10>".  In order to keep Org from
exporting such lines, the first column of a line should contain
only "/".  However, for convenience, there is now a special case:
If the entire row contains only such markers, the line will
automatically be discarded during export, even is the first
column is not "/".

**** Allow Macro calls to span several lines.

Macro calls may now span several lines, to write several
arguments in a cleaner way.  The result of a macro call can also
span several lines, by inserting the string "\n" (backslash
followed by n) into the value in the macro definition.

These were requests by Stefan Vollmar.

*** Misc

**** Quick access to all links in an entry

If =C-c C-o= is called while the cursor is in a headline, but not
directly on a link, then all links in the entry will be offered
in a small menu.  If there is only a single link, it will be
followed without a prompt.

**** Visibility Cycling: Allow to show all empty lines after a headline
    
=org-cycle-separator-lines= can now be set to a negative value,
to indicate that, if the number of empty lines before a visible
entry is greater than the specified number, then *all* empty
lines should be shown.

This was a request by "PT" whatever this means.

**** Allow language names to replace some strange major mode names

Sometimes a language uses a major mode which can't be guessed
from it's name.  There is now a new variable =org-src-lang-modes=
which can be used to map language names to major modes when this
is the case.  This is used when editing a source-code 
block, or when exporting fontified source-code with htmlize.

Thanks to Eric Schulte for a patch to this effect.

**** iswitchb support for many completion prompts
    
This is enabled using =org-completion-use-iswitchb=, and follows
the same model of usage as for ido users.

Thanks to John Wiegley for a patch to this effect.

**** New commands to set the effort property of an entry

There is now a special command, =C-c C-x e= to set the =Effort=
property of an entry.  From the agenda you can even use =e=.
If you have set up allowed values for the =Effort= property, then
using a prefix argument will directly select the nth allowed
value.  For example, in the agenda, =5 e= will select the 5th
allowed value.

This was a request by Michael Gilbert

**** Edit src works now better with killing buffer

Thanks to Dan Davison for a patch to this effect
