Timefold Solver 2.0 is now available, and the team demonstrates the upgrade process by migrating 15 quickstart projects in under 10 minutes. The migration is largely automated via an OpenRewrite recipe that handles package restructuring and deprecated API changes with a single Maven command. The main manual steps are updating the Java baseline from 17 to 21 and fixing downstream code affected by ConstraintCollectors type changes (Integer to Long). Only 2 of 15 projects required manual intervention. The post also outlines a 5-step upgrade plan for existing 1.x users and promotes free trials of the Plus and Enterprise editions.
