 **BREAKING**: Removed all deprecated exports, and removed support for the old backend system.
 
+It also removes the `CodeOwnersProcessor` from the default set of processors, because it is expensive to run and has vague semantics. You need to update your backend to add it to the `catalogProcessingExtensionPoint` if you wish to continue using it.
+
 The following removed exports are available from `@backstage/plugin-catalog-node`:
 
 - `locationSpecToMetadataName`
