 ## 1.1.0 (12/14/2023)
 
-Support retention durations for Cookies in the config and category level
+- Updated cookie config to include retention durations at both category and cookie levels.
+- Introduced an optional boolean field `sessionCookie` in cookie config to accommodate session cookies.
+- Implemented a setExpiryForCookie hook that adjusts the cookie's expiration in the following manner:
+  - If the sessionCookie parameter is enabled, the expiry is set to session
+  - If an expiry is specified at the cookie level, it takes precedence; otherwise, the expiry is derived from the category's expiration setting.
