+  # 
+  # Two repository configs require changes before upgrading:
+  # 1) SecObserve
+  # - Replace "baseBranches" with "baseBranchPatterns".
+  # - Replace "pip_requirements.fileMatch" with "pip_requirements.managerFilePatterns".
+  # - Remove "binarySource" from renovate.json because it is now a global-only option.
+  # 2) ny-tlc-report
+  # - Replace "config:base" preset with "config:recommended".
+  #
+  # Note: The validator only test the config files and does't check runtime behaviour etc
