+- feat: ignore errors in matchers and add format byte
+
+The CRD tester now can ignore certain errors. For example:
+
+```yaml
+suite: test ClusterSecretStore
+template: tests/crds/clustersecretstore.yml
+tests:
+  - it: matches ClusterSecretStore correctly
+    asserts:
+      - matchSnapshot:
+          path: tests/__snapshot__
+          # We deliberately want to test all the included elements.
+          ignoreErrors:
+            - "in body should have at most 1 properties"
+```
