SteamOS 3.9.5 — First Stable Build of the Branch: Linux Kernel 7.2 and KDE Plasma 6.7

⚡ The gist in 5 seconds - Valve has shipped SteamOS 3.9.5 — the first stable release in the 3.9 series. - Inside: Linux kernel 7.2 and the KDE Plasma 6.7 desktop environment. - Everything previously tested in the 3.9 preview builds has now moved to the stable channel. ### 🔍 What was found Phoronix reports: on Friday, Valve released SteamOS 3.9.5 — the first stable build of the 3.9 branch. The release wraps up the preview cycle: improvements that were previously available only to testers are now stable. Key highlights include the move to Linux kernel 7.2 and KDE Plasma 6.7 as the desktop environment, plus other updates the outlet mentions in passing. Essentially, this is the moment when the 3.9 branch's work stops being an experiment: what used to catch bugs in the preview channel now becomes the baseline configuration. The full changelog and details on each item are in Phoronix's article linked to the release. ### 💡 Why it matters The kernel and desktop environment in SteamOS are what determine hardware support and the behavior of Desktop Mode on the Steam Deck and third-party SteamOS devices. The move to Linux 7.2 and Plasma 6.7 sets a new baseline for the entire 3.9 branch, and future patches will build on it. The source doesn't specify exactly when the update will reach console owners in the stable channel — Phoronix only notes the fact of the 3.9.5 release itself.
