[opus] Integrating 1.1-beta

[Boris Grozev]

Hello,

We've been using Opus for VoIP calls in Jitsi and we're very happy with 
the sound quality it provides. Thank you for the great work!

We are thinking of updating to 1.1-beta and wanted to know if there's 
any reason not to do so at this point, and wait for the 1.1 release 
instead. Is the beta expected to be as stable as the 1.0.x series, or 
are there any known flaws still to be corrected?


Regards,
Boris
