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.

Add doc option to enable building documentation, defaulting to off.
Bump PKGREVISION, even though package didn't package before except if

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.
Changelog:
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.
