Apr 1, 20262026-04 monthly highlights for questdb/questdb focused on reliability improvements and security hardening in the build and CI/CD. Key changes include upgrading the Go build to Go 1.25.9 for better compatibility and performance, and tightening CI/CD security by gating the Gitleaks license validation workflow to run only when a valid license is present. These actions reduce build risk, improve runtime efficiency, and strengthen the release pipeline's security posture.
