Polaris v1.3.2

Polaris v1.3.2 is a reliability release focused on stream lifecycle, Linux private-session isolation, reconnect recovery, and truthful host diagnostics.

Highlights

  • Added first-class Linux stream-mode and private-runtime selection, including Gamescope Stream and Headless Dongle paths while retaining compatibility with legacy headless settings.
  • Hardened Gamescope ownership and nested teardown with generation-pinned socket reclamation, shared shell/C++ locking, atomic session credentials, exact private-SID/pidfd cleanup, and fail-closed portal/idle recovery.
  • Hardened RTSP follow-up control admission, live-session command ownership, session teardown, portal/PipeWire release ordering, and serialized PulseAudio operations.
  • Prevented private-stream controller input from also navigating host Steam Big Picture while preserving normal game input.
  • Hardened private Steam teardown and relaunch ordering, including waiting for the prior Steam singleton to be fully released without broadly terminating desktop Steam.
  • Preserved authenticated web sessions across host restarts and improved recovery from transient host outages.
  • Tolerated near-target stream FPS so healthy sessions are not mislabeled as degraded, and improved Linux GPU/capture-path diagnostics.
  • Added path-aware Dashboard preview and web configuration for the Linux runtime and capture modes included in this release.
  • Updated the Browser Stream WebTransport stack to webtransport-go v0.11.1 / quic-go v0.60.0, fixing remote memory exhaustion from unknown capsule buffering (CVE-2026-57497 / GHSA-g35j-m5xg-vh3q).

Packages

Release assets are provided for:

  • Arch Linux (Polaris-arch-x86_64.pkg.tar.zst)
  • Fedora 44 (Polaris-fedora44-x86_64.rpm)
  • Ubuntu 24.04 (Polaris-ubuntu24.04-x86_64.deb)

Packages install Polaris and its web console. Host integration remains an explicit sudo polaris --setup-host step.

Known validation limitation

End-to-end Control gameplay, streaming, audio, and controller validation against the final Polaris/Nova pair was not completed because the generic-handheld harness remained incompatible. The candidate was never activated in those failed harness attempts and is not implicated; release policy accepted this missing smoke as non-blocking. This release does not claim that integration smoke passed.

Issue #211 remains open as a known non-blocking Linux headless capture/conversion issue demonstrated on Polaris 1.3.1; it is not established as a 1.3.2 regression.
