In Oct 2025 (apache/creadur-rat), the team focused on stabilizing release processes, cross‑platform reliability, and preparation for the 0.17 release, delivering targeted features and robust fixes that drive cloud/CI efficiency and build stability. Key features delivered include release-engineering automation, 0.17-release readiness, and cross‑platform stability improvements. Notable work: - Release engineering and build automation: adding PR numbers to archive names to prevent GitHub Actions clashes, aligning Jenkins site-build commands, and enhancing release tooling for smoother canary deployments. - 0.17 readiness and configuration: 0.17‑style configuration updates, removal/cleanup of legacy release links, and preparation of POMs for release 0.17 plus associated release notes and canary homepage deployment. - Changelog, release notes, and automation: reformatted and prepared release notes for ASF release announcements, updated PMD/Dependabot changelogs, and improved artifact naming in CI. - Stability and GC/workarounds: Windows GC cleanup improvements, Linux green-build workaround, and GC‑related tests to stabilize flaky builds; changelog entries added. - JDK/infra experimentation and build hygiene: experiments with using JDK on ASF infrastructure, downscaling to JDK16 to diagnose Javadoc issues, and aligning configuration with 0.17 style across environments. - Quality fixes and automation: fixed copy-paste errors in Mockito exclusions and variable definitions, corrected Dependabot filters for non‑JDK8 items, and fixed artifact upload naming to prevent AlreadyExists errors. Impact: these changes reduce build failures, accelerate release readiness, and improve cross‑platform reliability, enabling faster delivery of features to customers with fewer integration issues. Technologies/skills demonstrated: Java/Maven-based build and release tooling, Jenkins and GitHub Actions integration, 0.17 ASF release workflow, JDK version management (including JDK16), PMD tooling, changelog/release-note automation, and cross‑platform resource/resource-cleanup strategies.

August 2025 (apache/creadur-rat) focused on stability and risk mitigation rather than feature delivery. No new features were released this month. A key maintenance action was taken to disable the Maven changelog plugin pending an upstream fix, ensuring no erroneous behavior or build instability. This change preserves release readiness and reduces risk while the upstream issue is resolved (commit b52fcf62c0ba2624efcc2f3178e4cf5b20d63cff; upstream issue: https://github.com/apache/maven-changelog-plugin/issues/200).
