 # Changelog
 
+## 2025-08-30 - 5.3.1 - fix(client(tspmIpcClient))
+Use bare topic names for IPC client subscribe/unsubscribe to fix log subscription issues
+
+- Updated ts/client/tspm.ipcclient.ts to call ipcClient.subscribe/unsubscribe with the bare topic (e.g. 'logs.<id>') instead of prefixed 'topic:<...>'.
+- Added comments clarifying that the IpcClient registers the 'topic:' prefix internally.
+- Fixes incorrect topic registration that could prevent log streaming handlers from receiving messages.
+
 ## 2025-08-30 - 5.3.0 - feat(cli/daemon/processmonitor)
 Add flexible target resolution and search command; improve restart/backoff and error handling
