+11.1.0 (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.
+ - Updated SDK_READY_FROM_CACHE event when using the `LOCALSTORAGE` storage type to be emitted alongside the SDK_READY event if it has not already been emitted.
+ - Updated @splitsoftware/splitio-commons package to version 2.1.0.
+
 11.0.4 (January 9, 2025)
  - Bugfixing - Updated @splitsoftware/splitio-commons package to version 2.0.3, which properly handles rejected promises when using targeting rules with segment matchers in consumer modes (e.g., Redis and Pluggable storages).
