 * FEATURE: add Darwin binaries for [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/) to the release flow. The binaries will be available in the new release.
 * FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent/): allow using HTTP/2 client for Kubernetes service discovery if `-promscrape.kubernetes.useHTTP2Client` cmd-line flag is set. This could help to reduce the amount of opened connections to the Kubernetes API server. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5971) for the details.
 * FEATURE: [vmalert](https://docs.victoriametrics.com/vmalert/): `-rule` cmd-line flag now supports multi-document YAML files. This could be useful when rules are retrieved via HTTP URL where multiple rule files were merged together in one response. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6753). Thanks to @Irene-123 for [the pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6995).
