 All notable changes to this project will be documented in this file.
 
+## 2.6.15 - 2026-08-08
+
+### Fixed
+
+- Slide update media sync on the player now removes uploads that were removed from the slide, so player storage stays aligned with the current slide content.
+- Routine player and player-bridge media upload/delete logs were removed to keep remote player and bridge operation quieter.
+- Background task descriptions no longer repeat the player slug when the task key already ends with that player name.
+
+## 2.6.14 - 2026-08-08
+
+### Fixed
+
+- Slide updates and template deletes now fan out media sync work across all live players instead of targeting only one player.
+
 ## 2.6.13 - 2026-08-08
 
 ### Fixed
