+New Features
+```````````````
+
+- Improves CPU utilization and vertical scaling of the |k8s-op-short| and
+  achieves faster reconciliation of all managed resources by allowing you
+  to control the number of reconciliations the |k8s-op-short| can perform
+  in parallel.
+
+  You can set ``MDB_MAX_CONCURRENT_RECONCILES`` for the |k8s-op-short| deployment
+  or ``operator.maxConcurrentReconciles`` in the |k8s-op-short| installation
+  Helm chart. If not provided, the default value is 1. The ability to control
+  the number of reconciliations might lead to an increased load on the |onprem|
+  and the |k8s| API server in the same time window. Observe the |k8s-op-short|
+  resource usage and adjust ``operator.resources.requests`` and
+  ``operator.resources.limits`` if needed. To learn more,
+  see :k8s:`Resource Management for Pods and Containers </concepts/configuration/manage-resources-containers/>`
+  in the |k8s| documentation.
+
+- Adds support for OpenShift 4.15. To learn more, see :ref:`k8s-compatibility`.
+
+Helm Chart Installation Changes
+```````````````````````````````
+
+- Adds an ``operator.maxConcurrentReconciles`` parameter that allows
+  you to control the number of reconciliations the |k8s-op-short| can
+  perform in parallel. The default value is 1.
+- Adds the ``operator.webhook.installClusterRole`` parameter that
+  controls whether to install the cluster role allowing the |k8s-op-short|
+  to configure admission webhooks. Set this parameter to false when
+  the cluster roles aren't allowed. The default value is ``true``.
+
+Bug Fixes
+```````````
+
+* **MongoDB** resource: Fixes a bug where configuring a MongoDB resource
+  with multiple entries in :setting:`spec.agent.startupOptions` would cause
+  additional unnecessary reconciliation of the underlying ``StatefulSet``.
+* **MongoDB, MongoDBMultiCluster** resources: Fixes a bug where
+  the |k8s-op-short| wouldn't watch for changes in the X-509 certificates
+  configured for {+mdbagent+} authentication.
+* **MongoDB** resource: Fixes a bug where boolean flags passed to
+  the {+mdbagent+} can't be set to ``false`` if their default value is ``true``.
