+## 1.5.12 - 2026-07-26
+
+### Changed
+
+- Shared web UI helpers are now loaded once in the admin shell and reused across the dashboard, admin, and template editor.
+- Template lists now show slide counts, and the template editor tracks which regions are already in use.
+
+### Fixed
+
+- Template editing now blocks removal of regions that are still referenced by slides.
+
+## 1.5.11 - 2026-07-26
+
+### Added
+
+- Video regions are now supported end to end, including player rendering, admin editing, playlist scheduling, and player sync.
+
+### Changed
+
+- The slide, template, and playlist flows were updated so video content can be created, configured, and scheduled alongside existing region types.
+- Player rendering and related media handling now recognize the new video region implementation.
+
+### Fixed
+
+- Region and upload handling were adjusted so video media syncs cleanly through the player and web admin paths.
+
 ## 1.5.10 - 2026-07-26
 
 ### Added
