FLAC 1.4.3 (23-Jun-2023)
As there have been additions to the libFLAC interfaces, the libFLAC version number is incremented to 13. The libFLAC++ version number stays at 10.
General
All PowerPC-specific code has been removed, as it turned out those improvements didn’t actually improve anything
Large improvements in encoder speed for all presets. The largest change is for the fastest presets and for 24-bit and 32-bit inputs.
Small improvement in decoder speed for BMI2-capable CPUs
Various documentation fixes and cleanups (Mark Grassi, Jake Schmidt)
Various fixes (Ozkan Sezer, Zhipeng Xue, orbea, Sam James, Harish Mahendrakar)
Fix building on Universal Windows Platform (Dmitry Kostjučenko)
flac
A lot of small fixes for bugs found by fuzzing
Various improvements to the –keep-foreign-metadata and –keep-foreign-metadata-if-present options on decoding
The output format (WAV/AIFF/RF64 etc.) is now automatically selected based on what kind of foreign metadata is stored
Decoded file is checked afterwards, to see whether stored foreign format data agrees with FLAC audio properties
AIFF-C sowt data can now be restored
Add –force-legacy-wave-format option, to decode to WAV with WAVEFORMATPCM where WAVE_FORMAT_EXTENSIBLE would be more appropriate
Add –force-aiff-c-none-format and –force-aiff-c-sowt-format to decode to AIFF-C
The storage of WAVEFORMATEXTENSIBLE_CHANNEL_MASK is no longer restricted to known channel orderings
Throw an error when WAV or AIFF files are over 4GiB in length and the –ignore-chunk-sizes option is not set
Warn on testing files when ID3v2 tags are found
Warn when data trails the audio data of a WAV/AIFF/RF64/W64 file
Fix output file not being deleted after error on Windows
Removal of the –sector–align option

metaflac
A lot of small fixes for bugs found by fuzzing
Added options –append and –data-format, which makes it possible to copy metadata blocks from one FLAC file to another
Added option –remove-all-tags-except
Added option –show-all-tags (harridu, Martijn van Beurden)
libFLAC
No longer write seektables to Ogg, even when specifically asked for. Seektables in Ogg are not defined
Add functions FLAC__metadata_object_set_raw and FLAC__metadata_object_get_raw to convert between blob and FLAC__StreamMetadata
Build system
Autoconf (configure)
The option –enable-64-bit-words is now on by default
CMake
The option ENABLE_64_BIT_WORDS is now on by default
Testing/validation
Fuzzers were added for the flac and metaflac command line tools
Fuzzer coverage was improved
