## Documenting Breaking Changes

If your PR introduces a breaking change (e.g., changing a default value, removing a flag, altering reconciliation behavior), you must update the [Breaking Changes](/docs/breaking-changes) page.

upcoming only, or does this page also track previously communicated and shipped breaking changes?

Good point - this should track both upcoming and previously shipped breaking changes. Do you have a list of previous breaking changes that I can add here? I'll update the wording once we have those documented

…ces (#46)

## Description of changes

Builds on #37 (cross-namespace default change). Adds user-facing documentation for the `enableCrossNamespace` Helm value / `--enable-cross-namespace` controller flag introduced in [runtime#239](aws-controllers-k8s/runtime#239) and [code-generator#699](aws-controllers-k8s/code-generator#699).

### Changes
- **`guides/helm-values.md`**: Add a `Cross-Namespace References` section documenting the `enableCrossNamespace` value (type, default, description, and deprecation warning).
- **`concepts.md`** (Field References): Add a warning noting that resource and secret references can target another namespace, gated by `enableCrossNamespace`, with links to Breaking Changes and the Helm value reference.
- **`guides/field-export.md`** (Security Considerations): Correct the previous "same namespace only" statement to reflect the current cross-namespace default and the upcoming change, with cross-links.

These cover all three behaviors gated by the flag: resource references (`*Ref`), secret references (`SecretKeyReference`), and `FieldExport` targets.
