Secpar 3.12.0

Desktop streams can now keep their network session and audio output running while the window is covered or minimized. Video resumes at a fresh keyframe when the window returns.

A full UI queue previously blocked authenticated keepalives and could end the stream. UI updates are now bounded and coalesced without blocking network traffic. Stale routes are re-probed after silence. Reopening audio output updates the live audio route without reconnecting.

Verification includes a real TLS/WebSocket/encrypted-UDP stream with its UI paused longer than the host timeout, continuous audio delivery, video keyframe recovery and migration to a new endpoint. Twelve client tests, 32 Windows desktop tests and 36 Linux desktop tests passed. Final Linux package checks cover real generated sound output, silence recovery, ALSA fallback, the new UI-independent audio worker and native Wayland rendering. Windows shared-output worker startup was checked with silence only.

Linux VA-API performance is still under investigation. The native GPU renderer has not been replaced in this release; the displayed software fallback remains important diagnostic information.

Windows and Linux downloads each include hosting and connecting. The host streaming engine is unchanged, so the existing Windows host can keep running while you update the Linux client. Android remains on 3.11.1 with the new Lucide menu icons and its accepted streaming engine.
