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 fixes in draft-ietf-codec-opus-update-06

 . Many other bug fixes, including integer wrap-arounds discovered
