* **New Features** * Added an opt-in runtime liveness watchdog with diagnostics, health status, and optional automatic restart. * Added configurable stream cleanup capacity and eviction re-entry protection. * Expanded configuration and UI access for users with playlist or user permissions, with safer data sanitization. * Added testkit scenarios and reporting for playback, admission, provider limits, sharing, and VOD behavior. * Added support for experimental-branch Docker builds. * **Bug Fixes** * Improved provider prioritization, shared playback capacity, cleanup, reconnect handling, and concurrent client behavior. * Fixed playlist parsing for declared media types. * Release links now use the configured destination.
