Hi everyone,

I'm pleased to announce version 0.6.0 of CELT, with many quality
improvements. This includes better stereo coupling, better handling of
transients, and better handling of highly tonal signals. In addition,
packet loss robustness has been improved through the optional use of
independent (intra) frames. CELT now supports a larger dynamic range,
suitable for encoding 24-bit audio (float version only). There is also a
very early VBR implementation.

Now, 0.6.0 is also the version that just got submitted as an "IPR-free
codec" Internet draft:

For those who aren't aware of it, there is an ongoing discussion about
creating an IETF working group for standardising unencumbered audio
codecs that everyone can use. There will be a BoF at the next IETF
meeting (26-31 July) in Stockholm to discuss that. I encourage those
interested in taking part in the mailing list discussion (
https://www.ietf.org/mailman/listinfo/codec ) and/or attending the BoF
in Stockholm. I will be co-chairing this BoF with Jason Fischl from Skype.
