Valve’s Steam Frame news feed posted SteamOS 0.4.2 (Beta) on Sep 29, and GamingOnLinux plus Linux Compatible confirmed the same changelog for owners still WAITING on reservation shipments. The build is the THIRD Steam Frame OS update since the Sep 14 launch, and it lands only DAYS after 0.4.1. Opt-in LIVES under Settings > System > System Update Channel.

Streaming reliability, not a FEATURE dump
Valve’s note is SHORT. Under Streaming it lists IMPROVED audio reliability and IMPROVED connection reliability, including a fix for “protocol error 17.” GamingOnLinux reprints those lines as the HEADLINE of the beta. That error class is the kind of wireless DROP that has chased PC VR streaming for YEARS; Valve is treating it as a SPECIFIC target rather than a vague stability claim.

Proximity detection and SteamVR 2.18.1
Under General, Valve says user PROXIMITY detection is IMPROVED — the logic that decides whether the headset is ON your face. Linux Compatible notes that 0.4.1 already overhauled that sensor model; 0.4.2 is another POLISH pass. The OS release ALSO bundles SteamVR 2.18.1, the same runtime Valve has been shipping in parallel for Linux streaming hosts.

Dongle troubleshooting stays a SEPARATE track
Mixed News (Sep 30) covered Valve’s public frame-dongle-troubleshoot.sh script for third-party Linux hosts. It warns owners whose Wi-Fi REGULATORY domain has NO 6 GHz band NOT to switch the PC to “US,” and recommends USB TETHERING with developer mode instead. That script is NOT part of the 0.4.2 changelog, but it sits beside the same STREAMING stack the beta is trying to HARDEN.
What owners should EXPECT
Valve still labels 0.4.2 as beta software. ROLLBACK is through the same System Update Channel control. Pricing remains $1,059 (256 GB) or $1,299 (1 TB) with controllers, the Wi-Fi 6E adapter, and Half-Life: Alyx in the kit, per Valve’s store listing. The WEEKLY OS cadence — 0.3.0, then 0.4.1, now 0.4.2 — reads as a LAUNCH backlog chewed through while many buyers have NOT received hardware YET.
