 # Breaking Changes in 9.0.0
 
+## Common
+
 ### Trial and commercial users now use the same product package
 The trial and commercial product versions merged into a single unified distribution package. The product access now depends on a license key file. This eliminates the need for separate trial downloads. For more information, please refer to the [Telerik License Key](slug:installation-license-key).
 
 ### .NET Support
 
-Telerik UI for Blazor 9.0.0 targets .NET 8 and no longer supports .NET 6 and .NET 7. For more information, see [System Requirements](slug:system-requirements).
