The SteamOS 2.119 update was pushed a few hours ago to the Brewmaster Beta channel, and it looks like it picks up a new kernel (linux, firmware-free, and firmware-nonfree), specifically Linux 4.11.8, to fix a crash that occurred when using the PlayStation 4 Dual Shock controller with the Steam for Linux client. Besides that, the SteamOS 2.119 Beta release borrows a few of the latest security patches from the Debian GNU/Linux 8 “Jessie” software repositories, including for the Apache2 web server to fix five vulnerabilities, the GnuTLS secure communications library, as well as the expat, libffi, and libgcrypt20 libraries.
