Changelog:
Apr 12, 2019
This Opus 1.3.1 minor release fixes an issue with the analysis on
files with digital silence (all zeros), especially on x87 builds
(mostly affects 32-bit builds). It also includes two new features:
A new OPUS_GET_IN_DTX query to know if the encoder is in DTX
mode (last frame was either a comfort noise frame or not encoded
at all)
A new (and still experimental) CMake-based build system that
is eventually meant to replace the VS2015 build system (the
autotools one will stay).
1.2.1
This Opus 1.2.1 minor release fixes a relatively rare issue where
the 1.2 encoder would wrongly assume a signal to be bandlimited to
12 kHz and not encode frequencies between 12 and 20 kHz. This only
happens on a few clips, but it is good to update to avoid a potential
loss of quality.
1.2.
This Opus 1.2 major release brings many quality improvements, new
features, and bug fixes. You can read all the details in this release
demo page. Changes since 1.1.x include:
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-06 (the mono downmix and the folding fixes need --enable-update-draft)
Many bug fixes, including integer wrap-arounds discovered through fuzzing (no security implications)
This Opus 1.1.4 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, our
own analysis shows that no remote code execution is possible.
However, we are making this release as a precaution.
This Opus 1.1.3 release focuses mainly on optimizations and bug
fixes. Changes include:
* Neon optimizations improving 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 1.1.2 includes:
Fixes encoder or decoder state reset, which would previously
disable some run-time selected architecture-specific optimizations;
and
Fixes hybrid mode discontinuous transmission (DTX) operation,
where the comfort noise above 8 kHz was incorrectly estimated
and could oscillate in time.
None of these bugs were regressions over previous releases.
This Opus 1.1.1 release brings many optimizations to the encoder
and decoder, including:
* x86 SSE, SSE2 and SSE4.1 intrinsics optimizations with run-time
CPU detection contributed by Cisco Systems,
* MIPS intrinsics optimizations contributed by Imagination
Technologies,
* ARM Neon optimizations contributed by Linaro and ARM,
* many architecture-independent optimizations and memory footprint
reductions that should improve performance on all platforms,
and
* several minor bug fixes.
The quality of the encoder should be mostly unchanged compared to
version 1.1.

and update to 1.1
Changelog:
Opus 1.1 includes:
new analysis code and tuning that significantly improves encoding quality, especially for variable-bitrate (VBR),
automatic detection of speech or music to decide which encoding mode to use,
surround with good quality at 128 kbps for 5.1 and usable down to 48 kbps, and
speed improvements on all architectures, especially ARM, where decoding uses around 40% less CPU and encoding uses around 30% less CPU.

Version 1.0.2 released
6 December, 2012
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. Other changes include fixes and improvements
to the PLC and hybrid mode quality improvements. As usual, this
release is fully compliant with the Opus specification.
Opus is a totally open, royalty-free, highly versatile audio codec.
Opus is unmatched for interactive speech and music transmission
over the Internet, but also intended for storage and streaming
applications. It is standardized by the Internet Engineering Task
Force (IETF) as RFC 6716 which incorporated technology from Skype's
SILK codec and Xiph.Org's CELT codec.
