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-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
