+### Fixed
+
+- Prevented agents from panicking when a WebSocket connection ends. The
+  WebSocket library transfers ownership of a successful upgrade stream to
+  the connection and leaves the HTTP response body nil; attempting to close
+  that body caused agents to restart and left forget jobs permanently stuck
+  in `running`. ([#37])
+- Manual forget jobs now receive the same per-source-group retention policies
+  as scheduled forget jobs. The API also supports a validated `--dry-run`
+  option through the complete server-to-agent-to-restic path, and rejects
+  hosts without configured retention before creating a job. ([#36])
+- Corrected the admin-credentials help text to reflect that forget uses normal
+  append-only credentials and blank admin credentials do not provide a
+  fallback for prune. ([#34])
