KoalaSync Changelog

All notable changes to the KoalaSync browser extension and relay server.

[v2.0.1] — 2026-06-01

Video detection on Prime Video: findVideo() now scores all video elements by size, duration, and mute state instead of picking the first one. Fixes 0×0 placeholder being selected over the actual player.
History entries in debug report showing ? instead of action names.
Prime Video status in compatibility matrix updated to reflect partial support.

Multi-video overview table in Copy Debug Report when a page has more than one <video> element. Shows resolution, mute state, playback state, readyState, duration, and marks the currently targeted video.

6-Language UI: The browser extension is now fully translated into English, German, French, Spanish, Portuguese (Brazilian), and Russian. Switch languages instantly in Settings without reload.
Real-Time i18n: Every label, button, tooltip, toast notification, empty state, and onboarding guide updates dynamically when the language changes.
6-Language Website: Landing page, join page, legal pages, and the interactive extension mockup now available in all 6 languages with proper hreflang tags.

Copy Debug Report: The Copy Logs button in the Status tab now copies a fully formatted Markdown report containing system info, connection status, video debug data, action history, and logs — ready to paste into GitHub issues.
Platform Auto-Detection: The Dev tab now identifies streaming platforms (YouTube, Netflix, Twitch, Prime Video, Disney+, HBO Max, Vimeo, Dailymotion) and displays the detected platform.
Enhanced Video Debug Info: 20+ new fields in the Status tab including network state, buffered ranges, dimensions (with 0×0 warning), media error codes, shadow DOM status, seeking/ended/loop flags, volume, playback speed, and data attributes.
No-Video Diagnostic Mode: When no video is found, the Status tab shows platform, page title, video count, shadow DOM presence, and MediaSession data to help troubleshoot.

New TwoPointZero Branding: Updated extension icons (16/32/48/96/128px), website favicon (PNG 16×16 + 32×32), Apple touch icon (192×192), and web manifest icons.
Larger Logo Display: Popup logo increased to 48px; website nav logo to 64px with improved vertical centering.
Higher Quality AVIF: Build script AVIF quality raised from 70 to 80, speed improved from 6 to 4, and minimum file size threshold removed so all assets get AVIF variants.
Prime Video Unblocked: Removed amazon. from the tab blacklist so Amazon/Prime Video tabs appear in the video selector.
Improved Browser Detection: Debug report now includes the full User-Agent string for accurate browser identification.
