 {project-first} 2.10 introduces the following features and enhancements:
 
-* In {project-short} 2.10.1, you can migrate VMs that are running on B-tree file systems (Btrfs) to {virt} with support for OS conversion.
+* In {project-short} 2.10.6, you can control nested virtualization behavior during migration with the new `enableNestedVirtualization` option. This option accepts three values:
+
+** Not set (default): Nested virtualization is automatically detected from the source VM and preserved on the target.
+** `true`: Force enables nested virtualization on the target VM, regardless of source settings.
+** `false`: Force disables nested virtualization on the target VM, regardless of source settings.
++
+This option gives you the flexibility to mitigate performance issues stemming from Virtualization Based Security (VBS) activation. 
++
+By disabling VBS on target VMs during the migration of Windows VMs that do not need nested virtualization, you can avoid potential performance degradation, resulting in a more streamlined and efficient migration process.
++
+[NOTE]
+====
+After you migrate your VMs to {virt}, you can re-enable VBS by running the following YAML:

 * In {project-short} 2.10.0, a `PreFlightInspection` during warm migration enables early detection of issues during guest conversion. If an issue is detected, the warm migration fails before VM shutdown, and users can adjust VM settings or skip guest conversion.

-* *Technology Preview:* In {project-short} 2.10.0, you can live migrate VMs from one OpenShift (OCP) cluster to another, minimizing downtime with the continuous availability of VMs during the migration process. With this update, MTV creates and maps resources from the source to the destination cluster and triggers the live migration, and {virt} CNV migrates the running VM.

+XFSv4 migrations failed::
+{project-short} 2.10.1 was rebased to {rhel-first} 10, which does not support XFS version 4 (XFSv4). As a result, XFSv4 migrations failed for {project-short} 2.10.1-2.10.5. With this release, a new `spec.xfsCompatibility` option is available on the migration plan. When set to `false`, the default setting, the plan uses the standard conversion image. When set to `true`, the plan uses the XFS-compatible conversion image instead of the standard conversion image. 
++
+[WARNING]
+====
+If you enable XFS support for a migration plan, then the plan cannot support Btrfs migration.

+Migrations with shared disk migration disabled failed::
+
+In {project-short}, migration of shared disks is done by running two migration plans, one with the `migrateSharedDisk` option set to `true` and one with the option set to `false`. Before this update, the migration plan with the option set to `false` failed because an unnecessary `populator` pod was created. With this release, the unnecessary pod is not created, and migration of shared disks works as expected.
