March 2026 (elastic/official-images) focused on security, compatibility, and reproducibility through comprehensive base-image refreshes and precise pin updates across the language runtimes and stack images. Delivered 17 image updates across OpenJDK, Go, Python, Ruby, Bash, Julia, Ghost, WordPress, Drupal, Docker, RabbitMQ, HAProxy, UBI pins, and related images, with targeted upstream version bumps and sha-based pin refreshes. Key actions included upgrading OpenJDK and Go base images, refreshing multiple upstream images to latest stable or tip versions, and updating UBI pins to latest digests to improve security posture and reproducibility. Notable upgrades include Python 3.12.x/3.11.x/3.10.x (and 3.15 RC to 3.15.0a7), Go tip updates, Ghost 6.19.4, WordPress 6.9.x, Drupal 11.3.x, Docker 29.x/Buildx 0.32.x, and UBI pins to latest sha. The changes are traceable to upstream commits with bot credits, and include a dedicated RubyGems JRuby test update. Overall this month strengthened security, reduced drift, and accelerated downstream adoption by keeping images current and reliably pinned.
