January 2026 (2026-01) monthly summary for EnterpriseDB/cloudnative-pg: Security hardening, reliability improvements, and documentation enhancements delivered. Key features include enforcing Azure authentication validation in barman-cloud to require explicit storage credentials and disallow mixed authentication parameters, clarifying and tightening the authentication flow. Major bug fixes improve operational stability: pod logs streaming follow mode no longer exits prematurely; designated primary transition race condition resolved using CurrentPrimary with retries; timeline history download validation prevents crash-loops during split-brain scenarios. Additional improvements targeted test reliability and performance: optimized test resource usage, more robust startup/recovery probes, and linting/preallocation improvements. Documentation updates (Docusaurus navigation, CNCF metadata, API docs) improve clarity and onboarding. Build provenance mitigation reduces metadata size without sacrificing attestations. Business value: stronger security posture, more reliable failover and streaming experiences, faster and cheaper test cycles, and clearer contributor/docs ecosystem.
