  • Version 1.0.3

    Released 29 Apr 2026 - 26.63 kB
    Works with firefox 142.0 and later
    v1.0.3
    • Fixed room routing so messages stay scoped to
      the correct room and host state follows the
      active room owner.
    • Hardened server validation for room IDs, URL
      sync payloads, protocol versions, and browser
      extension origins.
    • Added per-IP connection limits, safer
      shutdown handling, and clearer fatal error
      handling for rate limits, room limits, and
      version mismatches.
    • Fixed reconnect and URL-navigation races that
      could leave clients stuck, double-broadcast
      navigation, or retry forever after fatal server
      errors.
    • Improved video sync reliability with safer
      active-video detection, seek handling,
      playback-rate normalization, and remote-time
      compensation.
