+    Packages that follow SemVer are allowed to make breaking changes in _any_ `0.x` version, even `patch` and `minor`.
+    Check if you're using any `0.x` package, and see if you need custom `packageRules` for it.
+    When setting up automerge for dependencies, make sure to stop accidental automerges of `0.x` versions.
+    Read the [automerge non-major updates](./key-concepts/automerge.md#automerge-non-major-updates) docs for a config example that blocks `0.x` updates.
