 - Add `error_patterns_include` to Kyverno configuration to allow adding custom error patterns to the default set.
 - Add validation for `error_patterns_exclude` to ensure only valid default patterns can be excluded.
 
+### Breaking change
+
+- The `filter_extra` variable has been removed and replaced with `error_patterns_include` and `error_patterns_exclude`. To migrate:
+  - If you were using `filter_extra` to add custom error patterns, use `error_patterns_include` instead.
+  - If you need to exclude specific default error patterns, use `error_patterns_exclude`.
+  - See [examples/main.tf](examples/main.tf) for usage examples.
