Opus release 1.1.4

This release fixes a single bug. A specially-crafted Opus packet could cause
an integer wrap-around in the SILK LSF stabilization code. This would cause
an out-of-bounds read 256 bytes before a constant table. In most circumstances,
the consequences are harmless and the result is simply noise in the audio.

This was reported as CVE-2017-0381. Contrary to that report, we do not believe
that any remote code execution is possible. However, we are making this release
as a precaution.

Release 1.2-alpha2

This release changes the tonality analysis to run at 24 kHz, which reduces
complexity while giving better frequency resolution for the tonality
estimate. There's also a few bug fixes.

Release 1.2-alpha

This is an alpha release with many improvements, including:
- 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
- Support for all of the fixes in draft-ietf-codec-opus-update-04 (the mono
    downmix and the folding fixes need --enable-update-draft)
- Many bug fixes, including integer overflows discovered through fuzzing
    (no security implications)

Release 1.1.3

This is a minor release focusing mainly on optimizations and bug fixes.
Changes include:
- Neon optimizations inproving performance on ARMv7 and ARMv8 by up to 15%
- Fixes some issues with 16-bit platforms (e.g. TI C55x)
- Fixes to comfort noise generation (CNG)
- Documenting that PLC packets can also be 2 bytes
- Includes experimental ambisonics work (--enable-ambisonics)

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.
