We are happy to update three release branches: Libav 10.5, Libav 9.17, and Libav 0.8.16, which address a number of critical functional and security issues (many of which have CVE identifiers assigned) that we have been made aware of.

In the 0.8 release branch, the message about the deprecation of the "ffmpeg" program has been reworded to avoid confusion with the FFmpeg project.

For further details on the backported changes, please refer to our verbose Changelog files:
