During December 2024, Alban Bit-Monnot upgraded the Aries engine dependency in the aiplan4eu/unified-planning repository, raising the minimum required version from 0.3.3 to 0.4.0. This change enabled the project to benefit from recent bug fixes, performance enhancements, and new features introduced in the updated engine. Alban focused on dependency management using Python, ensuring that the integration maintained compatibility across all planning workflows and repository components. The work addressed the team’s goals of improving reliability and preparing for future integrations. While the contribution was focused and short-term, it demonstrated careful attention to technical detail and project stability.
