+
+|ak8so| 2.2.1
+-------------
+
+New Features, Improvements and Fixes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- All MongoDB images are now signed.
+- Removes CPU limits and increases memory limits to 1Gi and
+  memory requests to 256Mi.
+- Improves reconciliation of :ref:`Serverless Private Endpoints 
+  <ak8so-private-endpoint-serverless>`. |ak8so| no longer gets stuck in 
+  a reconcile loop that recreates serverless private endpoints when 
+  they fail to synchronize with |service|.
+- Ensures :ref:`Atlas Teams <ak8so-team>` are always cleaned up. This 
+  improvement prevents Atlas Team resources from being orphaned and left in a cluster with no associated projects.
+- Supports Kubernetes versions 1.27 through 1.29.
+- Supports OpenShift version 4.14.
+
+Deprecations and Removals
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- This release deprecates the following fields and setting them has no 
+  effect in serverless deployments:
+
+  - ``DiskIOPS``
+  - ``DiskTypeName``
+  - ``EncryptEBSVolume``
+  - ``InstanceSizeName``
+  - ``VolumeType``
+  - ``AutoScaling``
