Jan 1, 2025In January 2025, Genestack focused on improving documentation, reliability, and deployment safety. Documentation enhancements clarified complex infrastructure usage (OpenStack --service-type for subnet create; MariaDB mysqldump column-statistics; Grafana and Gateway API routes), while stability fixes strengthened storage and deployment tooling (multipath restart consolidation; Helm install script argument handling). These changes reduce operator error, shorten onboarding time, and improve system uptime across OpenStack, MariaDB, and Kubernetes-driven components.
