-<h3 id='zero.7.1'>0.7.1</h3>
-<p>CELT 0.7.1 improves the quality of the packet loss concealment (PLC), but
-does not change the rest of the codec. For this reason it is the first release
-<b>not</b> to break bit-stream compatibility with the previous release (0.7.0). But
-I promise not to do it again, the next CELT release will likely break
-compatibility once again. Note that the PLC improvements have not been
-completely converted to fixed-point yet, so the fixed-point still uses the old
-PLC. Last thing, the default name of the library was changed to libcelt0.so to
-make it easier to do the transition when the final 1.0 release comes out (with
-frozen bit-stream and API).

-<p>CELT 0.7.0 again improves the stereo quality, reduces artefacts at
-low bitrates (birdies and speech roughness) and fixes many bugs. In
-addition to the usual bitstream incompatibilities, the API has also
-changed in this release.

-<h3 id='zero.6.1'>0.6.1</h3>
-<p>CELT 0.6.1 improves the stereo quality, especially at lower bit-rates. This breaks bit-stream
-compatibility again, but only for stereo this time.

-<h3 id='zero.6.0'>0.6.0</h3>
-<p>This release brings in many quality improvements, including better stereo coupling,
-better handling of transients, and better handling of highly tonal signals. In addition,
-packet loss robustness has been improved through the optional use of independent (intra) frames.
-CELT now supports a larger dynamic range, suitable for encoding 24-bit audio (float version only).
-There is also a very early VBR implementation.
-The <a href="../testing/test.0.6.0.shtml">0.6.0 testing page</a> has more information about this release.

-<p>Version 0.5.2 has just been released with a few fixes over 0.5.1. On top of that,
-the pitch prediction was both improved and simplified. The other main change is a
-new bit allocation algorithm with better rounding and fine energy allocation. These changes
-resulted in considerable quality improvements at the smallest frame sizes. As with most prior releases this
-release breaks compatiblity with older bitstreams.

-packaging and deploying compatability versions of this prerelease
-alongside later, incompatible versions of celt. In addition, this

-<h3 id='zero.5.1'>0.5.1</h3>
-<p>This release fixes a number of issues with 0.5.0. Several cases
-where the encoder could fail have been fixed, including one that could cause memory
-corruption (and possibly a segfault). In addition, the VQ search has been improved,
-which results in a small CPU reduction, while fixing some quality problems with low
-frequency tones. Other than that, there should be no significant quality changes.
