This is the first quarterly maintenance update of Timefold Solver 1.x. With all forward development having shifted towards Timefold Solver 2.0.0 (to be released later this month), this release brings some bugfixes and a version bump of Quarkus.

In the next maintenance release, we will upgrade to the new Quarkus 3.33 LTS, and will stay on that branch for as long as possible.

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 : 1.32.0 dependency in your pom.xml to get started.

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 1.32.0) to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.
