 ## Upcoming Release
+* Added support for CustomV2 ssl policies for Application Gateway.
+    - Added `CustomV2` to the validation set of `PolicyType`
+    - Added `TLSv1_3` to the validation set of `MinProtocolVersion`
+    - Removed validation for null or empty cipher suites list since there can be empty cipher suites list for min protocol version of tls1.3
 
 ## Version 4.17.0
 * Supported `Microsoft.Network/privateLinkServices` in `Get-AzPrivateEndpointConnection` [#16984].
