June 2026 focused on hardening security posture and ensuring long-term compatibility for CMSgov/ab2d. Key work included consolidating security and compatibility upgrades: aligning the main Gradle Java version to 25 and updating dependencies (Netty, Tomcat) to address critical/high vulnerabilities. These changes reduce risk exposure, support future Spring Boot upgrades, and stabilize local/CI testing with adjustments for Java changes. The effort included Snyk remediation (AB2D-7273) and successful local tests plus end-to-end CI workflow validation.

Summary for 2026-05: Implemented a broad Java 25 upgrade across the AB2D platform (worker, API, Lambdas, and infra), with comprehensive updates to Dockerfiles, workflows, and base images to unlock newer runtime features, security updates, and performance benefits. Introduced a local testing harness to accelerate local development and debugging. Fixed critical build issues by correcting the Docker CMD blocks in API/Worker. Upgraded the AWS provider to v6 to maintain compatibility with Java 25 and prevent runtime errors. Streamlined CI/CD and security tooling with CodeQL workflow improvements (removing unnecessary steps and moving to GitHub runners) and security hardening via base image and dependency updates (Snyk, HAPI). These changes reduce risk, improve deployment reliability, and boost developer velocity across dev and production pipelines.

April 2026 (CMSgov/ab2d) delivered ARM64 migration across core services and completed security remediation to address critical/high-risk dependencies. The work focused on enabling ARM64-native builds and deployments, stabilizing CI/CD workflows, and reducing security risk in dependencies to improve portability, performance, and security for production workloads.

March 2026 (CMSgov/ab2d): Strengthened security posture, improved test reliability and CI/CD workflows, and expanded platform support. Delivered cross-environment HPMS key rotation with credential management, hardened CI/CD/test reliability, and ARM64 contract/runner readiness, enabling faster feedback and safer deployments.

February 2026 (CMSgov/ab2d) delivered important improvements to the start-job workflow and data reporting. Key features include FHIR R4V3 support in the start-job flow and a SQL update to retrieve organization names instead of contract names, improving data accuracy in reports. These changes enable developers to manually start FHIR v3 jobs from GitHub Actions and ensure more reliable metrics. The work aligns with AB2D-7111 and was validated by end-to-end workflow execution and database entry creation for v3 jobs.
