Apr 1, 2025April 2025 — Mautic/mautic delivered stability improvements and Symfony 7 readiness, positioning the project for safer upgrades and smoother deployments. Key features delivered: Symfony 7 compatibility and internal maintenance upgrades, including a refactor of MigrationFactory DI via a decorator and asset-copying enhancements to simplify deployment pipelines. Major bugs fixed: Graph Tables improved with type-safe rendering to prevent Twig type errors when non-string cell contents appear (fix committed under 6c7a08ae491fa20002f416df8c99cdbec2a49e64); and Migration Stability improved with consolidated pre-up assertion logic to skip when the target table does not exist or the index already exists (fix committed under 5bb9763e9bd0dca441609e84403d5ca5f0144c3e). Overall impact: Reduced upgrade-time risk, fewer runtime rendering errors, and clearer maintainability path, enabling safer releases and easier future enhancements. Technologies/skills demonstrated: PHP type-safety and Twig rendering safeguards, DI patterns and container-lite approaches, Symfony 7 upgrade readiness, and migration/asset tooling improvements.

Jan 1, 2025January 2025 monthly summary for mautic/mautic: Implemented Symfony 6 readiness improvements for the Marketing Message UI workflow with robust tests and a fix to AbstractStandardFormController to correctly retrieve date range values from the request, enabling reliable UI behavior after Symfony 6 upgrade. Delivered UI/UX enhancements to the right-hand menu on small screens with height limits and scrolling, and updated builder alert wording for clearer guidance. Strengthened asset handling to prevent 500 errors when assets are missing, ensured assets exist before download, and updated tests to verify 404 for non-existent assets. Fixed Date Modified field handling to prevent unintended overwrites by only setting the timestamp when supported, the getter exists, and the current value is null. Pursued internal code quality and refactoring to standardize DateTime usage, replace literals with constants in tests, and simplify conditional logic in the DashboardSubscriber for clarity and robustness. Overall, delivered tangible business value through improved reliability post-upgrade, enhanced mobile UX, reduced runtime errors, stronger data integrity, and reduced maintenance overhead through code quality improvements.

Nov 1, 2024November 2024 summary for mautic/mautic focused on upgrading to Symfony 6 while improving code quality, test reliability, and deployment readiness. Key features delivered include Symfony 6 core compatibility and API updates that reintroduced the session service, aligned controllers and return-types, removed deprecated APIs, and updated dependent bundles. These changes reduce upgrade risk for customers and prepare the codebase for future migrations. Additional work established automated code modernization tooling (Rector and PHPStan) to accelerate migrations and improve long-term maintainability, along with stabilization of the test environment to support migration activities. Autowiring and bundle organization were improved for GrapesJsData, ensuring proper service wiring and packaging. Critical Symfony 6 readiness bugs were addressed, including ensuring Twig service visibility is correct, handling deprecations to prevent future breakages, and correcting return types across the codebase. In parallel, the team invested in test reliability and performance by using real entities in tests, moving test execution earlier, and resolving time-related issues and flakiness. Overall impact: faster upgrade paths for customers, reduced risk of runtime/test failures during migration, and stronger QA foundations. Technologies/skills demonstrated: Symfony 6, PHPStan, Rector, autowiring, dependency injection, test-driven improvements, and CI/test stability engineering.
