- Fix off-by-one error in Seek end of stream check (see [#73](https://github.com/mewkiz/flac/pull/73)).
* Version 1.0.11 (2024-08-04)
- Move example tools to dedicated [mewkiz/flac-tools](https://github.com/mewkiz/flac-tools) repository to reduce external dependencies (see [#62](https://github.com/mewkiz/flac/pull/62)).
- Fix seek to frame start (see [#71](https://github.com/mewkiz/flac/pull/71)). Thanks to [Mark Kremer](https://github.com/MarkKremer).
- Simplify internal handling of io.Closer element in flac.Stream and flac.Encoder types (see [#70](https://github.com/mewkiz/flac/pull/70)). Thanks to [Mario Salgado](https://github.com/zalgonoise).
* Version 1.0.10 (2023-11-11)
- Add support for LPC audio sample encoding (see [#66](https://github.com/mewkiz/flac/pull/66)). Thanks to [Mark Kremer](https://github.com/MarkKremer) for bug fixes and [Mattias Wadman](https://github.com/wader) for the invaluable [fq](https://github.com/wader/fq) tool used to investigate FLAC encoding issues.
- Replace Travis CI with GitHub actions for CI build status, test status and code coverage [#64](https://github.com/mewkiz/flac/pull/64)). Thanks to [Mark Kremer](https://github.com/MarkKremer).
* Version 1.0.9 (2023-10-24)
- Fix integer overflow during unfolding of rice residual (see [#61](https://github.com/mewkiz/flac/pull/61)). Thanks to [Mark Kremer](https://github.com/MarkKremer).
- Fix decoding of escaped partition audio samples (see [#60](https://github.com/mewkiz/flac/issues/60)). Thanks to [Mark Kremer](https://github.com/MarkKremer).
- Handle frame hashing of audio samples with bits-per-sample not evenly divisible by 8 (see [9d50c9e](https://github.com/mewkiz/flac/commit/9d50c9ee99ba322f487ed60442dc16f22b2affb8)).
* Version 1.0.8 (2023-04-09)
- Fix race condition when reading meta data (see [#56](https://github.com/mewkiz/flac/pull/56)). Thanks to [Zach Orosz](https://github.com/zachorosz).
- Fix encoding of 8-bps WAV audio samples (see [#52](https://github.com/mewkiz/flac/pull/52)). Thanks to [Martijn van Beurden](https://github.com/ktmf01).
- Fix StreamInfo block type error message (see [#49](https://github.com/mewkiz/flac/pull/49)).
* Version 1.0.7 (2021-01-28)
- Add seek API (see [#44](https://github.com/mewkiz/flac/pull/44) and [#46](https://github.com/mewkiz/flac/pull/46)). Thanks to [Craig Swank](https://github.com/cswank).
* Version 1.0.6 (2019-12-20)
- Add experimental Encoder API to encode audio samples and metadata blocks (see [#32](https://github.com/mewkiz/flac/pull/32)).
- Use go.mod.
- Skip ID3v2 data prepended to flac files when parsing (see [36cc17e](https://github.com/mewkiz/flac/commit/36cc17efed51a9bae283d6a3a7a10997492945e7)).
- Remove dependency on encodebytes. Thanks to [Mikey Dickerson](https://github.com/mdickers47).
- Add 16kHz test case. Thanks to [Chewxy](https://github.com/chewxy).
- Fix lint issues (see [#25](https://github.com/mewkiz/flac/issues/25)).
* Version 1.0.5 (2016-05-06)
- Simplify import paths. Drop use of gopkg.in, and rely on vendoring instead (see [azul3d/engine#1](https://github.com/azul3d/engine/issues/1)).
- Add FLAC decoding benchmark (see [d675e0a](https://github.com/mewkiz/flac/blob/d675e0aaccf2e43055f56b9b3feeddfdeed402e2/frame/frame_test.go#L60)).
