Highlights include: * Rocky Linux 10 replaces Rocky Linux 9 as the only supported Rocky base image, removing the Delorean/CentOS Cloud SIG dependency and tightening RPM repository handling via "repos.yaml" (including a new versioned Erlang source for aarch64). * Data-plane services received major upgrades: "MariaDB" now tracks the 11.4 LTS series with the upstream health check script and the legacy clustercheck image removed, "ProxySQL" moves to 3.x, "Bifrost" consumes Ansible 11, "RabbitMQ" advances to 4.1, and "Gnocchi" is updated to 4.7.0. * Observability components were refreshed with "Fluentd" 6.x LTS, "OpenSearch"/"OpenSearch Dashboards" 3.x, broad "Prometheus" exporter and infrastructure bumps ("etcd", "helm", "letsencrypt- lego"), and the retirement of the "collectd", "telegraf", and "prometheus-ovn-exporter" images. * The container portfolio was streamlined: support landed for the "ironic-pxe-filter" image and "neutron-metadata-agent" wrapper scripts, while dormant services such as "ironic-inspector" and "Venus" were dropped.
