May 2025 monthly delivery across the Percona operators (MySQL, MongoDB, and XtraDB Cluster) with a focus on reliability, safety, and Kubernetes-aligned deployment practices. Delivered features and fixes that reduce operational risk, improve observability, and enable compatibility with newer Kubernetes and MongoDB versions. Key outcomes include safer secret handling, improved deployment semantics, and enhanced data-path correctness in monitoring contexts.

April 2025 delivered API simplifications, packaging enhancements, and observability improvements across Percona operators. Key outcomes include: (1) xtradb-operator API cleanup removing deprecated fields (exposePrimary.enabled) and legacy loadBalancerIP from CRD/Go structs; (2) Community OLM bundles packaging with bundle generation and distribution support across community, Red Hat, and marketplace channels; (3) targeted code cleanup removing deprecated finalizers to simplify lifecycle handling; (4) PostgreSQL operator enhancements adding repoHost resource limits, grants for public schema access with PostgreSQL v15+ validation, inclusion of sidecar example CRs, and enhanced reconciliation logging for misconfigurations; (5) cleanup in MySQL operator removing unused EnvMysqlshUserConfigHome constant. These changes reduce configuration complexity, enable safer upgrades, improve resource governance, and enhance diagnosability, delivering business value through streamlined deployments and lower maintenance overhead.

2025-03 monthly summary: Focused on configuration hardening and deployment reliability across Percona operators. No new features were delivered this month; major value came from safer defaults and corrected OpenShift permissions.
