+#### <a id="multi-tenant"/> Multi-tenant Imports
+
+Support for multi-tenant imports has been added to `MoveTables`. If you have a multi-tenant architecture where each
+tenant has their own database, you can import the tenants using multiple `MoveTables` workfows, one per tenant.
+Each import is initiated with the new `--tenant-id` flag. The column name (and data type) need to be specified in
+the VSchema of the target keyspace.

+#### <a id="vdiff-online-ddl"/> VDiff support for OnlineDDL migrations
+
+You can now run `VDiff`s on OnlineDDL schema change migrations, which are not yet cut over.
