SteamOS 2.88 was pushed earlier to the brewmaster_beta channel with an updated kernel from the Linux 4.1 LTS series, version 4.1.30, an updated AMDGPU-PRO graphics driver for AMD Radeon GPUs, the ttf-dejavu-core package to fix a font-related crash in the Steam update user interface, and all the latest security updates from the Debian Stable repos. The firmware-nonfree package has been updated as well in SteamOS 2.88 Beta to add firmware support for the Killer 1535 wireless module. Among the updated core components, we can mention the cURL data transfer tool, devscripts collection of scripts for Debian developers, and libgd2 GD graphics library.
