-11.1.0 (January XX, 2025)
+11.2.0 (January XX, 2025)
  - Added two new configuration options for the SDK's `LOCALSTORAGE` storage type to control the behavior of the persisted rollout plan cache in the browser:
     - `storage.expirationDays` to specify the validity period of the rollout plan cache in days.
     - `storage.clearOnInit` to clear the rollout plan cache on SDK initialization.
+
+11.1.0 (January 17, 2025)
+ - Added support for the new impressions tracking toggle available on feature flags, both respecting the setting and including the new field being returned on `SplitView` type objects. Read more in our docs.
  - Updated @splitsoftware/splitio-commons package to version 2.1.0.
