 ## 1.0.0
 
-Bundled with Termix 2.9.0.
+First release, bundled with Termix 2.9.0.
 
-- Session recording moved out of core's `/session_logs` routes and now serves
-  under `/plugin-api/session-recording` through core's connect pipeline.
-- Owns its data: core's `session_recordings` table is renamed to
-  `p_session_recording_session_recordings` on first activation.
-- New `session-recording.view` permission, given to the admin and user roles.
-- Offers `recordings.writer` to other plugins: `open()`/`append()`/`persist()`
-  for an incremental writer (ssh-terminal), `createFinished()` for a recording
-  already written to disk (remote desktop's guacd recordings).
-- Retention days becomes an admin plugin setting; per-host recording becomes
-  a host plugin setting.
+Records SSH terminal sessions so you can play them back, copy their text or download them. Old recordings are removed after a set number of days.
