 {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:

+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.
