+== `scopes` parameter now required for GitLab project deploy token creation
 
+The `scopes` parameter is now mandatory for the `gitlab:projectDeployToken:create` action. A valid value, such as `['read_repository']`, must be provided.

+== `dynamicPlugins.cache.volumeClaimSpec` removed, dynamic plugin storage now ephemeral (RHIDP-5568)
+
+The `dynamicPlugins.cache.volumeClaimSpec` field has been removed from `values.yaml`, making all dynamic plugin storage ephemeral by default. Instead of the Helm chart managing PVC creation, you must now manually configure ephemeral volume claims under `extraVolumes`.
+
+This change also resolves issues with running multi-replica {product-very-short} deployments, as using a Persistent Volume for the Dynamic Plugins cache previously led to potential write conflicts.
