The codec libraries will now be available under Xiph's BSD-like license. Over the next few days we will be transitioning normal operations off SourceForge and over to Xiph.org; first will be CVS and the web pages, followed by the mailing lists, bug tracker, and file release area. We will keep a mirror here until the transition is complete. It's OK to send patches to the flac-dev list but they won't be able to be integrated until CVS is fully moved over.

FLAC 1.1.0 released - 26 Jan 2003

I didn't get everything in that I wanted, but it's high time for a release. Note that the minor version has incremented, meaning forward compatibility was broken (forward compatibility means an earlier decoder can play all streams made by a later decoder). This is only because of a bug in 1.0.4 and prior where the decoder could not properly skip unknown metadata. The stream format itself has not changed and FLAC is still fully backward-compatible. All it means is that a FLAC file containing cue sheet metadata will not decode in older decoders. This bug is fixed in 1.1.0

There are a lot of improvements since 1.0.3, see the changelog for more

FLAC 0.7 released - 12 Feb 2001

This is mainly a bug fix release

FLAC 0.6 released - 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

FLAC 0.5 released - 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

FLAC 0.4 released - 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

FLAC debuts on SourceForge - 10 Dec 2000

The FLAC project is now being hosted on SourceForge. Visit the FLAC project page to join the mailing list or sign up as a developer
