Play, pause, seek - everyone stays in sync FEATURES - Real-time video synchronization - Built-in chat overlay (Ctrl+Shift+H) - No account required - Works across different locations Perfect for long-distance movie nights and watch parties. Change Log: v1.1.2 • Fixed an issue where YouTube page changes from the host could be missed while Sync Watch reconnected to a room. The latest host navigation now waits until the room connection is restored, then syncs automatically. • Also improved handling of failed joins, retries, sends, and disconnects. No new permissions. v1.1.0 • Redesigned extension popup and in-player chat. • Added live participant roster with Host and You indicators. • Added emoji reactions displayed over the video. • Improved room status, connection errors, and room-code copying. • Added automatic light and dark theme support. • Refreshed icons, typography, and overall interface. • No new browser permissions or data categories requested. v1.0.4 - Updated extension logo/icon assets for toolbar and store package consistency. - Hardened room routing and sync behavior to reduce cross-room or stale-room message issues. - Added broader sync correctness and security fixes. - Added server-side validation and anti-regression coverage. - Migrated core extension code toward TypeScript build output with expanded test coverage. - Fixed memory leak and reconnect/sync edge cases. 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. v1.0.2 - Rewrote video sync architecture for reliable cross-browser playback synchronization. Fixed echo loops causing play/pause jitter. Added URL validation for navigation commands. Improved drift correction with command cooldown. Removed unused permissions. v1.0.1: Improved connection stability for smoother sync Fixed keyboard shortcut (Ctrl+Shift+H) to work reliably on all streaming sites
