Valve has released a new Beta version of the next stable branch of its SteamOS gaming distribution based on Debian GNU/Linux, SteamOS 2.91, which was pushed to the brewmaster_beta channel on August 31, 2016.
The new SteamOS brewmaster update 2.91 is not a major milestone, as it only updates the kernel and firmware packages, namely linux ath10k, linux-latest, firmware-free, and firmware-nonfree to add the ATH10K_FW_FEATURE_IGNORE_OTP_RESULT variable for improving support for the ath10k wireless driver.
What that means exactly is that if you’re installing SteamOS on a desktop computer or laptop that sports a wireless adapter from Atheros, there’s a better chance for it to be supported, as well as to function within normal parameters. However, this is not a new patch in the Linux kernel, as it exists since May 2015.
