 ## [Unreleased]
 
+## [0.6.21] - 2025-10-16
+
+### Added
+
+- Reading position sync across devices using Nostr Kind 30078 (NIP-78)
+  - Automatically saves and syncs reading position as you scroll
+  - Visual reading progress indicator on article cards
+  - Reading progress shown in Explore and Bookmarks sidebar
+  - Auto-scroll to last reading position setting (configurable in Settings)
+  - Reading position displayed as colored progress bar on cards
+- Reading progress filters for organizing articles
+  - Filter by reading state: Unopened, Started (0-10%), Reading (11-94%), Completed (95-100% or marked as read)
+  - Filter icons colored when active (blue for most, green for completed)
+  - URL routing support for reading progress filters
+  - Reading progress filters available in Archive tab and bookmarks sidebar
+- Reads and Links tabs on `/me` page
+  - Reads tab shows nostr-native articles with reading progress
+  - Links tab shows external URLs with reading progress
+  - Both tabs populate instantly from bookmarks for fast loading
+  - Lazy loading for improved performance
+- Auto-mark as read at 100% reading progress
+  - Articles automatically marked as read when scrolled to end
+  - Marked-as-read articles treated as 100% progress
+  - Fancy checkmark animation on Mark as Read button
+- Click-to-open article navigation on highlights
+  - Clicking highlights in Explore and Me pages opens the source article
+  - Automatically scrolls to highlighted text position
+
+### Changed
+
+- Renamed Archive to Reads with expanded functionality
+- Merged 'Completed' and 'Marked as Read' filters into one unified filter
+- Simplified filter icon colors to blue (except green for completed)
+- Started reading progress state (0-10%) uses neutral text color
+- Replace spinners with skeleton placeholders during refresh in Archive/Reads/Links tabs
+- Removed unused IEventStore import in ContentPanel
+
+### Fixed
+
+- Reading position calculation now accurately reaches 100%
+- Reading position filters work correctly in bookmarks sidebar
+- Filter out reads without timestamps or 'Untitled' items
+- Show skeleton placeholders correctly during initial tab load
+- External URLs in Reads tab only shown if they have reading progress
+- Reading progress merges even when timestamp is older than bookmark
+- Resolved all linter errors and TypeScript type issues
+
+### Refactored
+
+- Renamed ArchiveFilters component to ReadingProgressFilters
+- Extracted shared utilities from readsFromBookmarks for DRY code
+- Use setState callback pattern for background enrichment
+- Use naddr format for article IDs to match reading positions
+- Extract article titles, images, summaries from bookmark tags using applesauce helpers
+
+## [0.6.20] - 2025-10-15
+
+### Added
+
+- Bookmark filter buttons by content type (articles, videos, images, web links)
+  - Filter bookmarks by their content type on bookmarks sidebar
+  - Filters also available on `/me` page bookmarks tab
+  - Separate filter for external articles with link icon
+  - Multiple filters can be active simultaneously
+- Private Bookmarks section for encrypted legacy bookmarks
+  - Encrypted legacy bookmarks now grouped in separate section
+  - Better organization and clarity for different bookmark types
+
+### Changed
+
+- Bookmark section labels improved for clarity
+  - More descriptive section headings throughout
+  - Better categorization of bookmark types
+- Bookmark filter button styling refined
+  - Reduced whitespace around bookmark filters for cleaner layout
+  - Dramatically reduced whitespace on both sidebar and `/me` page
+- Lock icon removed from individual bookmarks
+  - Encryption status now indicated by section grouping
+  - Cleaner bookmark item appearance
+- External article icon changed to link icon (`faLink`)
+  - More intuitive icon for external content
+
+### Fixed
+
+- Highlight button positioning and visibility
+  - Fixed to viewport for consistent placement
+  - Sticky and always visible when needed
+  - Properly positioned inside reader pane
+
+## [0.6.19] - 2025-10-15
+
+### Fixed
+
+- Highlights disappearing on external URLs after a few seconds
+  - Fixed `useBookmarksData` from fetching general highlights when viewing external URLs
+  - External URL highlights now managed exclusively by `useExternalUrlLoader`
+  - Removed redundant `setHighlights` call that was overwriting streamed highlights
+  - Improved error handling in `fetchHighlightsForUrl` to prevent silent failures
+  - Isolated rebroadcast errors so they don't break highlight display
+  - Added logging to help diagnose highlight fetching issues
+
+## [0.6.18] - 2025-10-15
+
+### Changed
+
+- Zap split labels simplified and terminology updated
+  - Removed redundant "Weight: xy" label to save space
+  - Changed "Author(s) Share" to "Author's Share" (possessive singular)
+  - Changed "Support Boris" to "Boris' Share" for consistency
+  - Weight value now shown directly in label (e.g., "Your Share: 50")
+  - Share and percentage now displayed on same line for cleaner layout
+- Zap preset buttons on desktop now expand to match slider width
+  - Added `flex: 1` to buttons for equal width distribution
+  - Buttons still wrap properly on smaller screens
+- PWA install section now always visible in settings
+  - Section shows regardless of installation or device capability status
+  - Button adapts with proper disabled states and visual feedback
+  - "Installed" state shows checkmark icon and disabled button
+  - Non-installable state shows disabled button
+
+### Fixed
+
+- PWA install button now properly disabled when installation is not possible on device
+  - Button only enabled when browser fires `beforeinstallprompt` event
+  - Removed hardcoded testing state that always showed button as installable
+- App & Airplane Mode section now always visible regardless of PWA status
+  - Image cache and local relay settings always accessible
+  - Previously entire section was hidden if PWA not installable/installed
+  - Only PWA-specific install button is conditionally affected
+
