opus (1.2~alpha2-1~16.04.york0) xenial; urgency=medium
* No-change backport to xenial
opus (1.2~alpha2-1) unstable; urgency=medium
* Run the tonality analysis at 24 kHz, which reduces complexity while giving
better frequency resolution for the tonality estimate.
* Speech quality improvements especially in the 12-20 kbit/s range.
* Improved VBR encoding for hybrid mode.
* More aggressive use of wider speech bandwidth, including fullband speech
starting at 14 kbit/s.
* Music quality improvements in the 32-48 kb/s range.
* Generic and SSE CELT optimizations.
* Support for directly encoding packets up to 120 ms.
* DTX support for CELT mode.
* SILK CBR improvements.
* Ensure that NLSF cannot be negative when computing a min distance between
them. This was reported and fixed in July, and assessed as having only a
relatively minor impact (garbage output, from the garbage input needed to
trigger it), or at very worst, an assertion failure or simple crash from
a slightly out of bounds read. In December it was assigned CVE-2017-0381
by someone other than the upstream developers, with claims of it being a
'Critical' issue on Android, but we're yet to see any analysis to back
that up. Closes: #851612
opus (1.1.3-1) unstable; urgency=medium
* Remove the generation date from the docs to improve reproducible builds.
Closes: #825345
* Fixes some corner cases with the soft clipper.
* Improve CBR and some other issues seen with using crazy low rates.
* More robustness fixes for reporting bad input.
* More optimisations, mostly for ARM.
* More precision fixes for edge cases.
* Fixes to comfort noise generation.
