YT re:Watch 4.0.3

🐛 Playback & Navigation Fixes

Enhanced playlist autoplay detection: Improved logic to detect playlist autoplay scenarios and delay timestamp restoration appropriately, preventing conflicts with YouTube's autoplay behavior.
Smart timestamp restoration: Added checks for significant viewing history (>30s) before attempting timestamp restoration to avoid unnecessary resets for short or unwatched videos.
Refined timing reset logic: Skip timing resets when videos are already playing near the beginning (within 5 seconds) to prevent unnecessary interruptions during playlist navigation. 
Improved SPA navigation handling: Enhanced single-page application navigation detection with better timestamp flag management and null video object protection. 

📊 Analytics & Statistics Improvements

Robust average duration calculation: Added Number.isFinite checks to prevent invalid duration calculations in analytics summaries.
Enhanced video tracking reliability: Improved timestamp reset logic and dataset flag management for better consistency across navigation types.

🗄️ Storage System Enhancements

Fixed date manipulation logic: Corrected retention days calculation to properly handle date arithmetic and prevent incorrect pruning of daily statistics.

🧪 Testing & Quality Assurance

Enhanced E2E test setup: Improved Playwright configuration with dedicated chromium-with-extension project for better extension testing.
Better navigation and consent dialog handling: Updated test suites to handle YouTube's cookie/consent dialogs and improve test reliability.
Jest setup improvements: Added ytStorage mock and exposed testing helpers for more comprehensive unit testing.
Memory management: Replaced WeakSet with Set for trackedVideos to allow manual management during testing.

YT re:Watch 4.0.1

🐛 Stats & Analytics Fixes

• Fixed inconsistent Analytics summary cards by rebuilding the persistent stats snapshot from the full hybrid history (IndexedDB + localStorage) and using it as the single source of truth.
• Summary cards (Total Watch Time, Videos Watched, Shorts Watched, Average Duration, Completion Rate, Playlists Saved) now read from the stored stats counters instead of only the currently loaded page.
• Activity (Last 7 Days) and Watch Time by Hour charts now use the same persisted daily/hourly stats snapshot (with local‑day keys and 24 hourly buckets) for stable, full‑history graphs.

🎬 Playlist Handling Improvements

• Improved playlist detection and title extraction across YouTube layout variants using a broader selector set and a retry‑based saver.
• Playlist “pause history” toggles are now more reliable and consistently respected when saving progress, preventing unwanted history entries for ignored playlists.

🧹 Data Hygiene

• Hybrid stats rebuilds now prune the daily stats map to the last 7 local days, keeping the snapshot compact and aligned with what the UI displays.

YT re:Watch 3.1.2

[3.1.2] - 2025-09-24

✨ New Features

• Persistent, privacy‑preserving watch‑time statistics stored locally (totalWatchSeconds, last 7 days daily, 24‑slot hourly)
• History list now shows the video channel name beneath the title

🧭 Behavior Changes

• Shorts tracking: save interval aligned to 5s and relaxed duration checks to avoid missed saves
• Initial stats seeding from existing history for accurate analytics on upgrade

📊 Analytics

• Summary cards and charts now prefer persistent stats for accuracy and performance
• Activity (last 7 days) and "Watch time by hour" use stored stats with local‑day keys

🔄 Sync & Performance (Firefox)

• Throttled storage.sync change listener to prevent self‑triggered loops; ignores self‑writes for 20s and enforces a 5‑minute minimum between listener‑triggered syncs
• Stats updates are debounced to the background cadence (default ~10 minutes) unless immediate sync is explicitly enabled

🗄️ Export/Import

• Export schema bumped to dataVersion: "1.1" and now includes a stats object

🐛 Fixes

• Improved timestamp validation and optimized timeupdate handling to reliably record progress
• Shorts tracking no longer skips saves when duration is unavailable

YT re:Watch 3.1.0

Highlights

• Add “Remove from history” button on YouTube thumbnails (hover to reveal)
• Add per‑playlist “Ignore videos” toggle (Playlists tab)
• Add global “Pause history in playlists” setting
• Default auto‑sync interval changed to ~10 minutes; immediate sync on updates disabled by default (Firefox only)

Details

• Thumbnail actions: Quickly remove individual videos from local history directly from YouTube thumbnails. Integrates with the deletion system so removed items stay deleted.

Playlist controls:

• Per‑playlist “Ignore videos”: When enabled for a playlist, progress for videos watched within that playlist isn’t saved.
• Global “Pause history in playlists”: Prevent saving progress for any playlist session until you turn it off.

Other changes:

• Sync (Firefox): Reduced background sync frequency to lower resource usage; immediate sync on updates now off by default. Manual sync remains available from Settings.
• UI and translations: Updated popup UI and all supported locales to expose the new playlist controls and messages.
• General: Minor stability and internal improvements.

YT re:Watch 3.0.1

✨ Major New Features

🔄 Tombstone-Based Deletion System

• Robust video deletion with tombstone markers to prevent deleted videos from reappearing after sync
• 30-day tombstone retention ensures deletion consistency across all devices
• Stale device protection automatically handles devices that haven't synced for 29+ days
• Cross-device deletion propagation ensures deletions are respected on all synchronized devices

🐛 Critical Bug Fixes

• Fixed deleted videos reappearing after sync operations
• Resolved immediate video restoration when delete button was clicked
• Enhanced popup filtering prevents deleted videos from appearing in the UI

🐛 Bug Fixes

• Video Overlay: Fixed an issue where the "viewed" overlay was not appearing on related videos in the right-hand column of a video page. This was caused by a YouTube UI update that introduced a new yt-lockup-view-model element, which is now correctly handled.

🚀 Core Stability

• Chrome MV3 Compatibility: Refactored the background script to use chrome.storage.session for state management, preventing state loss when the service worker becomes inactive. This fixes bugs related to popup handling and ensures reliable operation on Chrome.
• Enhanced Reliability: Replaced unreliable beforeunload events with pagehide and added defensive checks to prevent race conditions and errors during page unload.
• Improved Popup Handling: The extension now focuses the existing popup window instead of opening a duplicate if the action is triggered multiple times.

🛠️ Other Improvements

• Automatic tombstone cleanup and storage optimization
• Improved sync reliability with enhanced conflict resolution
• Better handling of offline devices and stale data scenarios
