 ENHANCEMENTS:
+* Consolidate airlock storage from 56 accounts to 2 using metadata-based stage management with ABAC workspace_id filtering. Reduces costs ~$7,943/month at 100 workspaces and speeds stage transitions 97-99.9% for most operations. ([#issue](https://github.com/marrobi/AzureTRE/issues/issue))
 * Upgrade Guacamole to v1.6.0 with Java 17 and other security updates ([#4754](https://github.com/microsoft/AzureTRE/pull/4754))
 * API: Replace HTTP_422_UNPROCESSABLE_ENTITY response with HTTP_422_UNPROCESSABLE_CONTENT as per RFC 9110 ([#4742](https://github.com/microsoft/AzureTRE/issues/4742))
 * Change Group.ReadWrite.All permission to Group.Create for AUTO_WORKSPACE_GROUP_CREATION ([#4772](https://github.com/microsoft/AzureTRE/issues/4772))
