+0.9.6 (June 29, 2023)
+ - Updated some transitive dependencies for vulnerability fixes.
+ - Updated @splitsoftware/splitio-commons package to version 1.8.3 that includes:
+    - Updated SDK_READY_TIMED_OUT event to be emitted immediately when a connection error occurs using pluggable storage (i.e., when the wrapper `connect` promise is rejected) in consumer and partial consumer modes.
+    - Bugfix - The `destroy` method has been updated to immediately flag the SDK client as destroyed, to prevent unexpected behaviours when `getTreatment` and `track` methods are called synchronously after `destroy` method is called.
+
 0.9.5 (May 15, 2023)
  - Updated @splitsoftware/splitio-commons package to version 1.8.2 that includes minor improvements.
     - Updated terminology on the SDKs codebase to be more aligned with current standard without causing a breaking change. The core change is the term split for feature flag on things like logs and IntelliSense comments.
