Valve haven't given up on their home-grown Linux distribution yet, with SteamOS seeing another beta update. Additionally, there's another Steam Client Beta update about.
As far as updates to SteamOS go, the last time they actually announced anything was with the 2.170 update back in January but they have actually been doing multiple newer builds since then you can see here. Just today, they officially announced the SteamOS 2.183 beta and the gist of it is this:
- mesa 18.3.4
- nvidia-graphics-drivers 415.27
- security updates
Newer drivers are especially useful and it's good to see Valve start to move a little more quickly on this, especially to keep up with Steam Play fresh drivers are needed. For details on how to get the SteamOS beta, Valve have this guide although it doesn't sound easy to revert back to a normal SteamOS install from the beta so it might be worth waiting until it's pushed out for everyone (unless you want to help test of course). See their announcement here.
A quick note too, Valve are also still advertising for a SteamOS Software Engineer.
As for the Steam Client Beta update, it's quite a small one which includes:
- Updated embedded Chromium build in Steam to 72.0.3626.121
- Fixed audio artifacts in web audio / friends notification sounds / voice chat for users with certain headsets that create multiple devices and have mono/single-channel chat output devices
From what Valve said on Twitter, this is likely the build that will require at least glibc 2.19.
