 ## Upcoming Release
 
 * Bug fix for `AzureFirewallPolicy` to ensure `BasePolicy` is properly set via `Set-AzFirewallPolicy` cmdlet either via pipe or direct value.
+* Removal of `SupportsShouldProcess` attribute from `Set-AzFirewallPolicyRuleCollectionGroup`, `Set-AzFirewallPolicy`, and `Set-AzFirewall` cmdlets as it has not been implemented yet.
 
 ## Version 7.22.0
 * Added new RouteTableUsageMode property for Network Manager Routing Configuration
