+The release notes for {mtc-full} ({mtc-short}) version 1.6 describe new features and enhancements, deprecated features, and known issues.
+
+[id="new-features-and-enhancements-1-6_{context}"]
+== New features and enhancements
+
+This release has the following new features and enhancements:
+
+* State migration: You can perform repeatable, state-only migrations by selecting specific persistent volume claims (PVCs).
+
+* "New operator version available" notification: The Clusters page of the {mtc-short} web console displays a notification when a new {mtc-full} Operator is available.
+
+[id="deprecated-features-1-6_{context}"]
+== Deprecated features
+
+The following features are deprecated:
+
+* {mtc-short} version 1.4 is no longer supported.
+
+[id="known-issues-1-6_{context}"]
+== Known issues
+
+This release has the following known issues:
+
+* On {product-title} 3.10, the `MigrationController` pod takes too long to restart. The Bugzilla report contains a workaround. (link:https://bugzilla.redhat.com/show_bug.cgi?id=1986796[*BZ#1986796*])
+
+* `Stage` pods fail during direct volume migration from a classic {product-title} source cluster on IBM Cloud. The IBM block storage plugin does not allow the same volume to be mounted on multiple pods of the same node. As a result, the PVCs cannot be mounted on the Rsync pods and on the application pods simultaneously. To resolve this issue, stop the application pods before migration. (link:https://bugzilla.redhat.com/show_bug.cgi?id=1887526[*BZ#1887526*])
+
+* `MigPlan` custom resource does not display a warning when an AWS gp2 PVC has no available space. (link:https://bugzilla.redhat.com/show_bug.cgi?id=1963927[*BZ#1963927*])
