Code
For IETF draft
 Code cleanup (any left?)
 Multichannel signalling (done, needs more testing)
 Make opuscompare fail for single seriously trashed frames
SILK issues
 PLC buffer not fully initialized (fix needs verifying)

Later

Exposed CELT constrained VBR 
Fixedpoint build 
Fix build system (right now it fails to build shared libraries, drops .o files all over) 
Floating point API  Usable commandline tools (
opus is a major regression from libcelt right now)  Smart automatic mode decision
 psymodel based VBR
 Remove copy in inverse MDCT
 Save some float<>int conversions
Spec
 Finish codec draft
 Ogg mapping (including multichannel). See: OggOpus
 RTP payload format
Other
 Logo
 Test vectors
 Listening tests
 Documentation (at a minimum every exported symbol should have complete and accurate documentation)
 Add content to opuscodec.org
 Oggzvalidate (should also validate opus toc)
 The above documentation
 Presentations
 Examples and test results (hyperlink to Monty's demo, gmaxwell's HA results page, etc)
 Useful example software (e.g. streaming software that works correctly) (opustools in xiph git)

Support for resampling in tools

Third party software
 Support in ekiga
 Support in mumble
 Support in asterisk
 Support in firefox (rtcweb and in ogg)
 Support in VLC
 Support in ogg123
 Support in ffmpeg
 Support in rockbox
 Support in foobar2000
 Support in gstreamer
 Support in mplayer
