Changelog opus (1.3.1-0.1build2)


opus (1.3.1-0.1build2) jammy; urgency=high

   * No change rebuild for ppc64el baseline bump.


opus (1.3.1-0.1build1) impish; urgency=medium

   * No-change rebuild to build packages with zstd compression.


opus (1.3.1-0.1) unstable; urgency=medium

   * Non-maintainer upload.
   * New upstream release (closes: #934809).


opus (1.3-1) unstable; urgency=medium

   * Enable support for ambisonics coding using mappings 2 and 3.
   * Use wideband encoding down to 9 kb/s.
   * Retrain RNN classifier weights to include reverberated speech.
   * Drop the explicit --enable-hardening from d/rules, it's enabled by default
     upstream now.

opus (1.3~beta+20180518-1) unstable; urgency=medium

   * Fix the CELT input NaN test.

opus (1.3~beta+20180516-1) unstable; urgency=medium

   * Snapshot from 652c4559f593d3aad78bd5c85a216eeae7859429 as a preview of
     patches pending for the 1.3 release.  The main motivation for doing this
     now is to pull in the fix for the PLC regression introduced just before
     1.2~alpha2, which Closes: #898690, and to get some broader testing on the
     new hardening checks before flipping the switch to enable those by default
   * Fix celt_pitch_xcorr() ARM jump table compiling error for a bug introduced
     in 1.2-rc1.
   * Better rate allocation for stereo SILK in hybrid mode.
   * Add RNN for VAD and speech/music classification.
   * Fixing bandwidth detection for 24 kHz analysis.
   * Enable RFC 8251 changes by default.
   * Better tuning for low-bitrate music.
   * Don't set _FORTIFY_SOURCE and -fstack-protector as part of the packaging
     anymore, the upstream build system will add them where they are supported
     and needed now.
   * Build with --enable-hardening, which isn't related to the compile options
     above, but instead includes additional opus-specific runtime sanity checks
     which are cheap and certain enough to use in production builds.
   * Use dh compat 9, not because it actually brings anything new which we need
     here, but it hushes the increasingly insistent warnings about deprecated
     compat levels, and is a baseline supported by all of the releases we still
     need to be able to support.  I'm going to say this Closes: #810258, since
     the rest of the 'modernisation' there mostly isn't helpful.  We've already
     been running the tests since the very first release, we release directly
     from upstream git and maintain upstream patches there, so format 3(quilt)
     adds nothing but pain, and we have upstream build and install targets that
     are designed to cleanly separate the -arch specific and -indep components,
     so regressing to make those codependent isn't very appealing either.  It
     would have also broken support for building where m-a wasn't supported,
     though that's less of a problem today than it was previously.


opus (1.2.1-1) unstable; urgency=medium

   * Fixes a bug in surround encoding causing very bad quality on loud signals
     beyond a certain amplitude.
   * Speech quality improvements especially in the 12-24 kbit/s range.
   * Music quality improvements in the 32-48 kb/s range.
   * More aggressive use of wider speech bandwidth, including fullband speech
     starting at 14 kbit/s.
   * Improved VBR encoding for hybrid mode.
   * SILK CBR improvements.
   * DTX support for CELT mode.
   * Support for directly encoding packets up to 120 ms.
   * Improves quality on files with powerful tones that cause MDCT leakage.
   * Fixes for speech/music detection at the very beginning of files.
   * Fixes an issue where the encoder can misdetect that the signal is SWB
     instead of FB, lowpassing the signal.

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.

   * Fixes max_decay for LFE in fixed-point.
   * Fixes patch_transient_decision() for hybrid mode.
   * Don't reset the RTCD arch on encoder/decoder reset.


opus (1.1.1-1) unstable; urgency=medium

   * Mostly just lots of new optimisation, with a few minor bug fixes and
     quality improvements.


opus (1.1-2) unstable; urgency=medium

   * Regenerate build system files, mostly to pull in a later libtool.m4
     which has fixes for building the ppc64le architecture.  Closes: #751982


opus (1.1-1) unstable; urgency=low

   * Bump to the final 1.1 release version.
   * Relax the shlibs and track real symbol versions from here on,
     now that we have a real stable release version in the distro.

opus (1.1~rc+20131204-1) unstable; urgency=low

   * Really 1.1-rc3, except 3 < + to dpkg.
   * Fixes fixed-point OPUS_SET_GAIN.
   * Fixes fixed-point stereo regression.

opus (1.1~rc+20131128-1) unstable; urgency=low

   * Fixes the EDSP asm for ARMv5TE.
   * Uses the actually intended NEON code.

opus (1.1~rc-1) unstable; urgency=low

   * Many encoder improvements, better tonality and speech/music probability
     estimation, temporal VBR, surround masking, numerous speed optimisations.

opus (1.1~alpha+20130512-1) unstable; urgency=low

   * Preview snapshot of the 1.1 release.  Mostly to give people who need some
     of the newer API functions for their own projects something to play with
     while we finalise the rest of what is planned for this one.
     The encoder should perform better (both for quality and bitrate) than the
     1.0.x releases, but please do report any regressions you find upstream
     so that they can be fixed.


opus (1.0.1-1) experimental; urgency=low

   * The RFC 6716 release.

   * Add the stack protector flags to /rules which got dropped from the
     upstream build system in -rc3 too.
   * Pushed to experimental for the new libav which needs the gain ctls.
     Closes: #690563

   * Add extern "C" protection to opus_multistream.h.
   * Warn about unused returns and NULL arguments for functions where that would
     always be an error in the calling code.
   * Clearly mark fixed point builds in the internal versioning.
   * Better documentation.
   * Suggest opus-tools.

opus (0.9.14+20120521-2) unstable; urgency=low

     Fixes the unit test timeout seen on the mips buildd.
   * Add some extra 'hardening' flags to those upstream uses already.

opus (0.9.14+20120521-1) unstable; urgency=low

   * Opus draft-14 release testing.
   * This one's for Sid.  Closes: #610980


opus (0.9.8-1) experimental; urgency=low

   * Opus draft-10 release testing.

opus (0.9.4-1) experimental; urgency=low

   * Initial (re)release as Opus.  Closes: #610980


celt (0.7.1-1) unstable; urgency=low

   * The "correlation does not imply causation" release.
     To celebrate the first release of celt that is actually compatible with a
     a previously distributed version, we've renamed the library!
   * libcelt is now libcelt0.  The intent from upstream being to make it clear
     that one of the above was an accident, and unlikely to be repeated soon.
     On the bright side, this means we should be getting proper soname bumps
     from now on when the code ABI changes.  The bitstream format still remains
     entirely fluid though, applications which communicate with a peer _must_
     check that the formats are compatible at runtime.  It may, and indeed is
     very likely to, continue changing with every release.
   * By some small miracle, this should be an entirely painless transition
     though.  The new package doesn't conflict with the existing one, and all
     rdeps except mumble will switch to the new package with a binNMU, but not
     be broken in the meantime.  They use the .pc file provided, and have been
     build tested.  The mumble package is waiting on this one before it can work
     properly anyway, so a fix for that is just waiting for this to get through
     the NEW queue first now.
   * The new PLC is reported to be working Really Well.


celt (0.7.0-1) unstable; urgency=low

   * Another day, another bitstream format.  Closes: #554559
   * Drop the IETF drafts for now.  Better to leave worrying about the
     paperwork for this until we have some documents that aren't actually
     supposed to expire in less than the life of a distro release.
     Closes: #538990 for now.  If you really need to reference them, then
     you should probably be tracking git anyhow, as they should be changing
     while the codec evolves too.

celt (0.6.1-1) unstable; urgency=low

   * New upstream release.  Closes: #511163


celt (0.4.0-1) unstable; urgency=low

   * New upstream release.

celt (0.3.2-1) unstable; urgency=low

   * New upstream release.

celt (0.3.0-1) unstable; urgency=low

   * Initial release.  Closes: #474392
