 # Changelog
 
+## 1.3.0 - 2026-09-15
+
+- Moved movie and series browsing out of the sidebar into a Jellyfin-style main collection grid.
+- Added click-through collection cards that open the selected movie or series folder details and episodes in the main panel.
+- Added a collection return action and kept sidebar controls focused on navigation, search, and rescans.
+
 ## 1.2.1 - 2026-09-15
 
 - Set the Docker Compose container host binding to `0.0.0.0` so Docker's localhost port mapping can reach h-player while keeping the host publish on `127.0.0.1`.

 h-player is a small local web app for browsing a folder-based private video collection. The interface follows Kaizoku's dark purple glass-panel design, including the same card gradients, rounded controls, cover fallback treatment, and accent colors. The app remains a standalone private library browser and does not integrate with Plex, Jellyfin, Kodi, or any external metadata provider.
 
+The sidebar holds app navigation, search, and rescanning controls. Movies and series appear in the main collection grid, similar to Jellyfin-style library browsing. Selecting a collection card opens that movie or series folder with its metadata, seasons, episodes, and playable files.
