 All notable changes to this project will be documented in this file.
 
+## 2.5.2 - 2026-08-03
+
+### Changed
+
+- Player page auth now writes a cookie for websocket reuse, and player and announcement sockets accept that cookie so they no longer depend on query-string tokens.
+- RSS and API region placeholder panels now use shared field-aware chip rendering, with updated spacing and defaults across the slide editor.
+- RTMP regions now default audio to enabled in the editor, and the slide rich-text editor no longer allows anchor tags.
+
+### Fixed
+
+- Player websocket auth now falls back to the `pulse_page_auth` cookie when the auth query parameter is unavailable.
+
 ## 2.5.1 - 2026-08-03
 
 ### Added
