SteamOS 2.68 Brewmaster Beta comes only three weeks after the previous Beta version 2.67, which added fixes to the built-in PulseAudio sound server and the GRUB bootloader.
This update follows Debian 8.4 ‘Jesse’ update and will be rebased upon it.
SteamOS now brings a new version of the APT package manager.
The announcement for 2.68:
A handful of minor updates to sync with the Debian 8.4 release and the usual collection of security fixes.
Remember to keep in mind that this is a Beta version of SteamOS and not the official release.
