Changelog

April 2026

  • Added Phase 1 TV power coordination on infoscreen/groups/{group_id}/power/intent.
  • Added POWER_CONTROL_MODE with local, hybrid, and mqtt behavior.
  • Added src/power_intent_state.json and src/power_state.json for power IPC and telemetry.
  • Added infoscreen/{client_id}/power/state publishing from simclient.py.
  • Added turn-off guard logic to avoid unintended TV-off races at event boundaries.
  • Added TV_POWER_RUNBOOK.md and test tooling in scripts/test-power-intent.sh.

March 2026

  • Hardened event-trigger screenshots (event_start, event_stop) against periodic overwrite races.
  • Improved latest.jpg and meta.json synchronization for reliable dashboard updates.
  • Added self-healing for stale or invalid pending screenshot trigger metadata.
  • Improved display environment fallbacks (DISPLAY=:0, XAUTHORITY) for non-interactive starts.
  • Allowed periodic idle captures in development mode so dashboard previews stay fresh without active events.
  • Added content-type-aware trigger delays for event screenshots.
  • Changed screenshot transmission to a 1-second polling tick so triggered sends fire within <=1s.
  • Migrated dashboard payload to grouped schema v2 (message, content, runtime, metadata).

November 2025

  • Implemented the two-process screenshot pipeline (display_manager.py capture, simclient.py transmission).
  • Added Wayland/X11 screenshot tool fallback chains.
  • Extended dashboard payloads with screenshot and system metadata.
  • Extended scheduler event type support for presentation, webuntis, webpage, and website.
  • Added website autoscroll support via CDP injection and extension fallback.
