+## Changelog
+
+### v1.0.2 — Subtitle & Analytics Polish
+
+This release focuses on making OfflineAcademy smoother for real course libraries, especially Udemy-style folders with external subtitle files.
+
+#### Added
+
+- Multi-language subtitle support for local course videos.
+- SRT and VTT subtitle detection during course scans.
+- Visible subtitle controls in the video player when tracks are available.
+- Support for multiple subtitle tracks per lesson, such as English and Persian.
+
+#### Fixed
+
+- Same-folder subtitle imports for files stored outside the app container and mounted into the course library.
+- Subtitle filename matching for common Udemy-style exports, including patterns like `-english-test.us.srt` and `-persian-test.us.srt`.
+- Lesson API subtitle ordering so tracks load consistently in the player.
+- Analytics page data loading by reading analytics directly on the server instead of relying on a fragile internal fetch.
+
+#### Improved
+
+- Course scanning now better handles real-world course folder layouts.
+- Subtitle files are served as browser-compatible `text/vtt`, including converted SRT files.
+- Local development workflow was verified on port `6969` after cache cleanup and rebuild.
