Steam OS 3.7.15

Valve launched A new version of the operating system for your handheld is available today. What's now available for download is Steam OS 3.7.15, a release arriving on the stable channel with many fixes, some of which are targeted at devices other than the Steam Deck. Specifically, the list of new features includes three improvements that are included in the "Non-Deck" section in the English version, and will be used by the Asus ROG Ally and the Lenovo Legion Go.

Personally, I have to say that I haven't installed it yet, and the reason is that I prefer to wait a bit to read the community comments; I don't want to end up like what happened with SteamOS 3.7.8, when WiFi started to do its thing and couldn't connect to my router. Valve promises many improvements, including fixes for power issues and the clock sometimes resetting after waking up the Steam Deck.
