+11.9.0 (November 26, 2025)
+ - Updated @splitsoftware/splitio-commons package to version 2.9.0, which:
+    - updates the SDK’s initial synchronization in Node.js (server-side) to use the `startup.requestTimeoutBeforeReady` and `startup.retriesOnFailureBeforeReady` options to control the timeout and retry behavior of segment requests.
+    - updates the order of storage operations to prevent inconsistent states when using the `LOCALSTORAGE` storage type and the browser’s `localStorage` fails due to quota limits.
+
 11.8.0 (October 30, 2025)
  - Added new configuration for Fallback Treatments, which allows setting a treatment value and optional config to be returned in place of "control", either globally or by flag. Read more in our docs.
  - Added `client.getStatus()` method to retrieve the client readiness status properties (`isReady`, `isReadyFromCache`, etc).
