Version 0.5.0 of CELT audio codec
Release Notes: This release includes simplifications to the bit allocation code, and includes a new low-complexity mode that can be enabled (without breaking compatibility) on the encoder side. There are several other optimizations and bugfixes included. The API has been slightly modified, so code using CELT will have to be updated (minor).
Other releases
Release Notes: This version fixes two minor bugs with 0.11 that affect the bit-stream. The quality should improve (very) slightly, but not enough to be noticeable in most cases. Several Opus-related bugs have also been fixed.
Release Notes: This release brings many quality improvements, mostly through better bit allocation. It also fixes many bugs and regressions, most notably with VBR support. The bit-stream is not compatible with version 0.9.x.
Release Notes: This release fixes the PLC that was broken in 0.9.0. No other changes were made beyond that. The bit-stream is compatible with 0.9.0.
Release Notes: This release mainly focuses on quality improvements. The transient handling code has been greatly improved and high-frequency artifacts have been reduced. There have also been lots of small improvements from better tuning of various parameters.
Release Notes: This release fixes some bugs introduced in 0.8.0. The bit-stream remains compatible with 0.8.0, with the caveat that CELT no longer supports frame sizes that have prime factors larger than 5. This should not affect any reasonable application.
