`v2.1.8` is a patch release scoped to fixing issues reported by users of Crossplane `v2.1` and fixing security related issues in Crossplane's dependencies.

#### 🎉 Highlights

* **Fixed repeated owner updates for composed Usages (#7622, originally #7591):** The Usage controller only checked the *first* `ownerReference` when deciding whether the `spec.by` resource already owned the Usage. A Usage created by a Composition already has the composite as its first owner, so `spec.by` ended up as a later owner and the controller issued an unnecessary update on every reconciliation — repeatedly re-triggering composition reconciliation and eventually opening the XR circuit breaker. It now checks all owner references.
* **Dependency security updates:** Bumps the Go toolchain to `1.25.12` (#7577), `grpc` / `golang.org/x/net` / `golang.org/x/text` (#7620, #7609), and the sigstore stack — `cosign` (#7556), `rekor` (#7555), `timestamp-authority` (#7568), `sigstore-go` (#7581) — to pick up upstream CVE fixes. See `## What's Changed` for the full list.
