   * Added annotations `consul.hashicorp.com/prometheus-ca-file`, `consul.hashicorp.com/prometheus-ca-path`, `consul.hashicorp.com/prometheus-cert-file`, and `consul.hashicorp.com/prometheus-key-file` for configuring TLS scraping on Prometheus metrics endpoints for Envoy sidecars. To enable, set the cert and key file annotations along with one of the ca file/path annotations. [[GH-1303](https://github.com/hashicorp/consul-k8s/pull/1303)]
 * Helm
   * Added `connectInject.annotations` and `syncCatalog.annotations` values for setting annotations on connect inject and sync catalog deployments. [[GH-775](https://github.com/hashicorp/consul-k8s/pull/775)]

This will require updating installed CRDs to include ReferenceGrant from the Gateway API v0.5 [Experimental Channel](https://gateway-api.sigs.k8s.io/concepts/versioning/#release-channels-eg-experimental-standard) if setting `apiGateway.enabled=true` [[GH-1299](https://github.com/hashicorp/consul-k8s/pull/1299)]
