Opus 1.1 just hit release candidate; pending any last minute bug discoveries or showstoppers, this will become the final 1.1 release.

The release candidate includes two major improvements over the previous 1.1 beta.

We've further improved surround encoding quality and tuning of both surround and stereo at lower bitrates. As an example, full 48kHz 5.1 surround is now tested and tuned down to 45kpbs (it's nowhere near audiophile quality at that rate, but it is surprisingly good).

In addition, we also landed additional encode/decode optimizations for all CPU types, but especially ARM which now includes NEON encoding optimizations.

And of course, we hopefully cleared the 1.1-beta buglist :-)
