This changelog is not exhaustive, review the git commit log for an exhaustive list of changes.

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.

FLAC 1.4.2 (22-Oct-2022)

Once again, this release only has a few changes. A problem with FLAC playback in GStreamer (and possibly other libFLAC users) was the reason for the short time since the last release

FLAC 1.4.1 (22-Sep-2022)

This release only has a few changes. It was triggered by a problem in the 1.4.0 tarball: man pages were empty and api documentation missing

FLAC 1.4.0 (09-Sep-2022)

As there have been changes to the library interfaces, the libFLAC version number is incremented to 12, the libFLAC++ version number is incremented to 10. As some changes were breaking, the version age numbers (see libtool versioning) have been reset to 0. For more details on the changes to the API, see the porting guide.

The XMMS plugin and ‘common’ plugin code (used only by the XMMS plugin) are deprecated, they will be removed in a future release.

FLAC 1.3.4 (20-Feb-2022)

This release mostly fixes (security related) bugs. When building with MSVC, using CMake is preferred, see the README under “Building with CMake” for more information. Building with MSVC using solution files is deprecated and these files will be removed in the future. As there have been no changes to the library interfaces, the libFLAC version number remains 11, and libFLAC++ version number remains 9.

Bug fixes:

FLAC 1.0 (20-Jul-2001)

It’s finally here. There are a few new features but mostly it is minor bug fixes since 0.10:

FLAC 0.10 (07-Jun-2001)

This is probably the final beta. There have been many improvements in the last two months:

FLAC 0.9 (31-Mar-2001)

Bug fixes and some new features:

FLAC 0.8 (05-Mar-2001)

Changes since 0.7:

FLAC 0.7 (12-Feb-2001)


FLAC 0.6 (28-Jan-2001)

The encoder is now much faster. The -m option has been sped up by 4x and -r improved, meaning that in the default compression mode (-6), encoding should be at least 3 times faster. Other changes:

FLAC 0.5 (15-Jan-2001)

This is the first beta version of FLAC. Being beta, there will be no changes to the format that will break older streams, unless a serious bug involving the format is found. What this means is that, barring such a bug, streams created with 0.5 will be decodable by future versions. This version also includes some new features:

FLAC 0.4 (23-Dec-2000)

This version fixes a bug in the constant subframe detection. More importantly, a verify option (-V) has been added to flac that verifies the encoding process. With this option turned on, flac will create a parallel decoder while encoding to make sure that the encoded output decodes to exactly match the original input. In this way, any unknown bug in the encoder will be caught and flac will abort with an error message.
