 # Changelog
 
+## 2026-04-20 - 1.19.0 - feat(oidc)
+persist hashed OIDC tokens, authorization codes, and user consent in smartdata storage
+
+- replace in-memory OIDC authorization code, access token, refresh token, and consent stores with SmartData document classes
+- store authorization codes and tokens as hashes instead of persisting plaintext values, with helpers for matching, expiration, and revocation
+- persist and merge user consent scopes when issuing authorization codes
+- add cleanup lifecycle management for expired OIDC state and stop the cleanup task when reception shuts down
+- add tests covering hashed code/token matching, authorization code usage, refresh token revocation, and consent scope merging
+
 ## 2026-04-20 - 1.18.0 - feat(reception)
 persist email action tokens and registration sessions for authentication and signup flows
