## 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.

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

:::warning[Breaking Change Notice]
The default value of `--enable-cross-namespace` will change from `true` to `false` in a future release.

We might explicitly say "The warning serves as a deprecation notice of existing default functionality". Up to you if you'd like to include that.
