   <CHANGES>
+### 2026.07.13.r001
+- Harden restore task validation and make confirmed in-place restores target original paths safely.
+- Serialize repository and managed-mount access, block unsafe force-unlock operations, and wait for task cleanup during daemon shutdown.
+- Bound snapshot browser memory, stream Restic diffs, continuously drain command output, and reject symlink-overlapping Rsync paths.
+- Activate persistent run logs and align package, WebGUI, and manifest versions during builds.
+
 ### 2026.07.10.r007
 - Serve snapshot browser folders as compact cached tree pages instead of sending the complete Restic file list to the browser.
 - Prevent large snapshots with hundreds of thousands of entries from failing with generic 500 responses during snapshot browsing.

   <CHANGES>
+### 2026.07.13.r001
+- Harden restore task validation and make confirmed in-place restores target original paths safely.
+- Serialize repository and managed-mount access, block unsafe force-unlock operations, and wait for task cleanup during daemon shutdown.
+- Bound snapshot browser memory, stream Restic diffs, continuously drain command output, and reject symlink-overlapping Rsync paths.
+- Activate persistent run logs and align package, WebGUI, and manifest versions during builds.
+
 ### 2026.07.10.r007
 - Serve snapshot browser folders as compact cached tree pages instead of sending the complete Restic file list to the browser.
 - Prevent large snapshots with hundreds of thousands of entries from failing with generic 500 responses during snapshot browsing.
