Opus 1.1

Same as 1.1-rc3, but bumped soname

Opus 1.1 release candidate 3

Fixed-point fixes: intensity stereo, OPUS_SET_GAIN, and Opus-custom

Opus 1.1 release candidate 2

Fixes ARMv5E alignment issues and improves Neon code

Opus 1.1 release candidate

Compared to 1.1-beta, this new release further improves surround encoding
quality. It also includes better tuning of surround and stereo for lower
bitrates. The complexity has been reduced on all CPUs, but especially ARM,
which now has Neon assembly for the encoder. At last, there are a few bugfixes.

Opus 1.1-beta release

This is a beta release of the upcoming 1.1 release. Compared to 1.1-alpha, it
mainly includes surround improvements, better VBR tuning, some improvements
to the speech/music detector, as well as many optimizations.

Opus 1.0.3 release

Opus 1.0.3 includes a backport of the new 1.1 surround API to that tools
can now switch to this API even when not using 1.1-beta. This release
also includes a few bug fixes.

Opus 1.1-alpha release

This is an alpha release for the upcoming 1.1 release. Compared to 1.0.2, it
includes quality improvements, optimizations, bug fixes, as well as an
experimental speech/music detector for mode decisions. All the fixes and
improvements from 1.0.2 are also in this release. The most important changes
are:

Quality-impacting

    Unconstrained VBR algorithm
    New transient detector
    Bitrate boost for tonal samples, which are harder to code
    Fixes to the tf analysis code
    Improvements to the hybrid mode code
    Fixed some mode switching issues
    More aggressive use of dynamic allocation
    Automatic audio bandwidth detection
    DC rejection filter

Optimizations

    Significant reduction of the decoder stack size requirement
    Optimization of several functions for the common case of zero

Opus 1.0.2 release

Opus 1.0.2 fixes an out-of-bounds read that could be triggered by a malicious
Opus packet causing an integer wrap-around in the padding code. Considering
that the packet would have to be at least 16 MB in size and that no
out-of-bounds write is possible, the severity is very low. This new release
also has the following changes:

== Quality-impacting ==
* Changed the behaviour of the PLC to always fill the caller's buffer
* Properly decode in-band FEC for packets with mutiple Opus frames
* Hybrid mode quality improvements and fixes
* Fixed bugs in the CELT mode PLC
* Redundant mode transition fixes

== Other changes ==
* Stack reduction
* Doc fixes (many)
* 16-bit fixes
* Misc build fixes
* New API calls: OPUS_GET_LAST_PACKET_DURATION ctl() and
  opus_packet_get_nb_samples()
* Minor code cleanup
