In this second beta release of Timefold Solver, we are bringing some features and quality of life improvements. Before we release the final version, we may still change or remove some APIs, and we will still introduce more documentation.

We are grateful to everyone in our community who decide to help us test this release. Check out our migration documentation to help you with the transition.

How to use Timefold Solver

To see Timefold Solver in action, check out the quickstarts.

With Maven or Gradle, add the ai.timefold.solver : timefold-solver-core : 2.0.0-beta-2 dependency in your pom.xml to get started.

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 2.0.0-beta-2) to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.
