I would just point out that Debian Wheezy users that download Jitsi stable build from the website, unaware of the issue discussed in the list under the "no sound transmitting with opus audio codec" thread will be left with an unusable package. It may be considered to
1) Release a new stable build for Debian, numbering it say 2.4.1 or
2) At least warn the users not to install that binary package on Wheezy, or to disable Opus
What do you think?
