Hi everyone,

I’m happy to announce a new release of the Prometheus exporter plugin for OpenSearch: version 3.8.0.0. As always, all plugin releases can be found on the GitHub releases page.

This release adds support for OpenSearch 3.8.0 and, alongside the usual maintenance updates, brings a new feature: the plugin now exposes the cluster.routing.allocation.enable cluster setting as a metric (`opensearch_cluster_routing_allocation_enabled`). You can find the complete release notes here:
