# v0.3.6 (TBD)
Theme: TBD
User-facing changes:
- `Number` and `RawMessage` type aliases are now available, so that
a user of lowmemjson's native APIs does not need to import
`encoding/json` or compat/json in order to use them.
# v0.3.5 (2023-02-10)
Theme: Compatibility bugfixes
User-facing changes:
- Decoder: Fixes a bug where if an EOF is encountered, the reader
is appended to, then another Decode is attempted, that EOF
poisons future Decodes. This is something that `encoding/json`
supports.
- Encoder: Fixes a bug where if an encode error is encountered, all
future Encode calls will fail. Reusing an Encoder is something
that `encoding/json` supports.
- compat/json.Encoder: Now buffers the output, to avoid partial
writes if an encode error is encountered. This matches the
behavior of `encoding/json`. For memory consumption reasons, the
native lowmemjson Encoder still does not buffer.
# v0.3.4 (2023-02-05)
Theme: Fix compilation with Go 1.20
lowmemjson uses git.lukeshu.com/go/typedsync.CacheMap (since
lowmemjson v0.3.1), which when compiled with Go 1.20 makes use of Go
1.20 language features. However, because lowmemjson's `go.mod` said
`go 1.18`, those language features are disabled and compilation
fails (see [go#58342][]). To work around this, lowmemjson's
`go.mod` now says `go 1.20`. Despite this, lowmemjson still works
fine with Go 1.18.
[go#58342]: https://github.com/golang/go/issues/58342
# v0.3.3 (2023-02-04)
Theme: Bugfix
User-facing changes:
- ReEncoder: Fixes a regression in v0.3.1 where it erroneously
enters compact mode when CompactIfUnder is set and write barriers
are in use.
- ReEncoder: Fixes a regression in v0.3.1 where it sometimes emits
extra (but syntactically valid) newlines when write barriers are
in use.
# v0.3.2 (2023-02-03)
Theme: Bugfix
User-facing changes:
- ReEncoder: Fixes a regression in v0.3.1 where it sometimes emits
extra (but syntactically valid) newlines.
# v0.3.1 (2023-01-31)
Theme: Performance
This release does a bunch of performance tuning and optimizations,
with no user-visible changes other than memory consumption and CPU
time. Based on benchmarks with a real-world use-case, it is now
roughly an order of magnitude faster, with much lower memory
consumption (the big-O of memory consumption was always pretty low,
but there were some big constant factors before).
# v0.3.0 (2023-01-30)
Theme: Breaking changes
This release makes a breaking change to the way *ReEncoder works.
This change both better fits what's convenient to use, and enables
making future performance improvements.
Breaking changes:
- ReEncoder: Instead of instantiating a `*ReEncoder` with
```go
reenc := &lowmemjson.ReEncoder{Out: w, settings}
```
it is now instantiated with
```go
reenc := lowmemjson.NewReEncoder(w, lowmemjson.ReEncoderConfig{settings})
```
# v0.2.1 (2023-01-30)
Theme: Code quality
This release improves code quality; getting various linters to pass,
adding tests (and a few bug-fixes), refactoring things to be
clearer, fixing some mistakes in the documentation.
User-facing changes:
- Encoder: `*EncodeMethodError` is now also used when a method
produces invalid JSON.
- Decoder: The offset in `*DecodeTypeError`s now correctly point
the start of the value, rather than somewhere in the middle of
it.
# v0.2.0 (2023-01-26)
Theme: Add documentation
This release doesn't make any major changes, and is just adding
documentation. I have removed a few minor things that I didn't want
to write documentation for.
Breaking changes:
- Drop the following shorthand functions:
+ `func Decode(r io.RuneScanner, ptr any) error { return NewDecoder(r).Decode(ptr) }`
+ `func DecodeThenEOF(r io.RuneScanner, ptr any) error { return NewDecoder(r).DecodeThenEOF(ptr) }`
+ `func Encode(w io.Writer, obj any) (err error) { return NewEncoder(w).Encode(obj) }`
- Drop `const Tab = "\t"`.
# v0.1.0 (2022-09-19)
Theme: Initial release
