In the May '24 release of Timefold Solver, we’ve focused on making everything more stable and reliable. Here’s what’s new:

• Connected Ranges Collector: This new feature helps manage and penalize the use of resources over time.
• Legacy Examples to Quickstarts: We’ve turned old examples into quickstart guides for easier use.
• Throttling Best Solution Consumer: For our Enterprise Edition users, we’ve added a feature to prevent integrations from being overloaded by solver events.
• Maven Repository Authentication: We’re preparing to require authentication for our Enterprise Edition binaries. We’ll notify customers in advance to ensure a smooth transition. Community Edition users won’t be affected, as their binaries will remain freely available on Maven Central.

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

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 1.10.0) to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.
