Jul 1, 2025July 2025 (dotCMS/core) delivered a substantial upgrade to API visibility, CI/CD reliability, and platform resilience, while strengthening developer productivity and observability. Key accomplishments include automating OpenAPI/Swagger generation and annotation rollout across services (SwaggerCompliant) with a refactor replacing runtime reflection scanning (Jandex), enhancing CI/CD with fail-fast pipelines and Semgrep-based checks (replacing SonarQube), establishing infrastructure monitoring via a dedicated management port and JMX debugging, and executing platform/runtime upgrades (Java 21, Ubuntu 24.04 base image, Hibernate Validator migration) to reduce risk and improve performance. Additional wins include Analytics Performance Testing Infrastructure, documentation restructuring for AI tooling readiness, and build-system improvements to ensure clean core-web builds. These changes collectively raise API quality, reliability, and developer velocity while lowering maintenance burden and enabling better capacity planning for performance and reliability initiatives.
