[1.3.0] - 2026-01-07

Added

• 🚀 Multi-Device Sync (Thanks to Thomas from Bielefeld for reporting!)

  • Automatic download of new notes from other devices
  • Deletion tracking prevents "zombie notes" (deleted notes don't come back)
  • Smart cleanup: Re-created notes (newer timestamp) are downloaded
  • Works with all devices: v1.2.0, v1.2.1, v1.2.2, and v1.3.0

• 🗑️ Server Deletion via Swipe Gesture

  • Swipe left on notes to delete from server (requires confirmation)
  • Prevents duplicate notes on other devices
  • Works with deletion tracking system
  • Material Design confirmation dialog

• ⚡ E-Tag Performance Optimization

  • Smart server checking with E-Tag caching (~150ms vs 3000ms for "no changes")
  • 20x faster when server has no updates
  • E-Tag hybrid approach: E-Tag for JSON (fast), timestamp for Markdown (reliable)
  • Battery-friendly with minimal server requests

• 📥 Markdown Auto-Sync Toggle

  • NEW: Unified Auto-Sync toggle in Settings (replaces separate Export/Auto-Import toggles)
  • When enabled: Notes export to Markdown AND import changes automatically
  • When disabled: Manual sync button appears for on-demand synchronization
  • Performance: Auto-Sync OFF = 0ms overhead

• 🔘 Manual Markdown Sync Button

  • Manual sync button for performance-conscious users
  • Shows import/export counts after completion
  • Only visible when Auto-Sync is disabled
  • On-demand synchronization (~150-200ms only when triggered)

  • MERGE: Keep local notes + add server notes
  • REPLACE: Delete all local + download from server
  • OVERWRITE: Update duplicates, keep non-duplicates
  • Restore modes now work correctly for WebDAV restore

[1.2.2] - 2026-01-06

Fixed

• Backward Compatibility for v1.2.0 Users (Critical)
  • App now reads BOTH old (Root) AND new (/notes/) folder structures
  • Users upgrading from v1.2.0 no longer lose their existing notes
  • Server-Restore now finds notes from v1.2.0 stored in Root folder
  • Automatic deduplication prevents loading the same note twice
  • Graceful error handling if Root folder is not accessible

Technical

• WebDavSyncService.downloadRemoteNotes() - Dual-mode download (Root + /notes/)
• WebDavSyncService.restoreFromServer() - Now uses dual-mode download
• Migration happens naturally: new uploads go to /notes/, old notes stay readable

  • No migration required for existing users

Changed

  • Example now shows: http://192.168.0.188:8080/notes

Technical

• WebDavSyncService.getMarkdownUrl() - Smart URL detection for both structures
• WebDavSyncService.exportAllNotesToMarkdown() - Exports all local notes with progress callback
• SettingsActivity.onMarkdownExportToggled() - Triggers initial export with ProgressDialog
