Unreleased

MPEG Encode/Decode Support.

Uses libmpg123 for decode, liblame for encode. Encoding and decoding support is independent of each other and is split into separate files. MPEG support is generalized as subformats, SF_FORMAT_MPEG_LAYER(I,II,III) so that it might be used by other containers (MPEG1WAVEFORMAT for example), but also contains a major format SF_FORMAT_MPEG for 'mp3 files.'

Encoding Status:
- Layer III encoding
- ID3v1 writing
- ID3v2 writing
- Lame/Xing Tag writing
- Bitrate selection command
- VBR or CBR
Decoding Status:
- Layers I/II/III decoding
- ID3v1 reading
- ID3v2 reading
- Seeking
New fuzzer for OSS-Fuzz, thanks @DavidKorczynski.
This CHANGELOG.md. All notable changes to this project will be documented in this file. The old NEWS file has been renamed to NEWS.OLD and is no longer updated.
Add support for decoding MPEG III Audio in WAV files.

SFC_SET_DITHER_ON_READ and SFC_SET_DITHER_ON_WRITE enums comments in public header, thanks @SmiVan (issue #677).
ENABLE_SNDFILE_WINDOWS_PROTOTYPES define is deprecated and not needed anymore.

Previously, in order for the sf_wchar_open() function to become available on the Windows platform, it was required to perform certain actions:
```
#include <windows.h>
#define ENABLE_SNDFILE_WINDOWS_PROTOTYPES 1
#including <sndfile.h>
```
These steps are no longer required and the sf_wchar_open() function is always available on the Windows platform.
Use UTF-8 as internal path encoding on Windows platform.

This is an internal change to unify and simplify the handling of file paths.

On the Windows platform, the file path is always converted to UTF-8 and converted to UTF-16 only for calls to WinAPI functions.

The behavior of the functions for opening files on other platforms does not change.
Switch to .xz over .bz2 for release tarballs.

Typo in docs/index.md.
Memory leak in caf_read_header(), credit to OSS-Fuzz (issue 30375).
Stack overflow in guess_file_type(), thanks @bobsayshilol, credit to OSS-Fuzz (issue 29339).
Abort in fuzzer, thanks @bobsayshilol, credit to OSS-Fuzz (issue 26257).
Infinite loop in svx_read_header(), thanks @bobsayshilol, credit to OSS-Fuzz (issue 25442).
GCC and Clang pedantic warnings, thanks @bobsayshilol.
Normalisation issue when scaling floating point data to int in replace_read_f2i(), thanks @bobsayshilol, (issue #702).
Missing samples when doing a partial read of Ogg file from index till the end of file, thanks @arthurt (issue #643).
sndfile-salvage: Handle files > 4 GB on Windows OS
Undefined shift in dyn_get_32bit(), credit to OSS-Fuzz (issue 27366).
Integer overflow in nms_adpcm_update(), credit to OSS-Fuzz (issue 25522).
ABI version incompatibility between Autotools and CMake build on Apple platforms.

Now ABI must be compatible with Autotools builds. Note that this change requires CMake >= 3.17 for building dylib on Apple platforms.
Fix build with Autotools + MinGW toolchain on Windows platform.

See https://github.com/msys2/MINGW-packages/issues/5803 for details.

Heap buffer overflow in wavlike_ima_decode_block(), thanks @bobsayshilol, credit to OSS-Fuzz (issue 25530).
Heap buffer overflow in msadpcm_decode_block(), thanks @bobsayshilol, credit to OSS-Fuzz (issue 26803).
Heap buffer overflow in psf_binheader_readf(), thanks @bobsayshilol, credit to OSS-Fuzz (issue 26026).
Index out of bounds in psf_nms_adpcm_decode_block(), credit to OSS-Fuzz (issue 25561).
Heap buffer overflow in flac_buffer_copy(), thanks @yuawn, @bobsayshilol.
Heap buffer overflow in copyPredictorTo24(), thanks @bobsayshilol, credit to OSS-Fuzz (issue 27503).
