v1.11.0: Timefold Solver 1.11.0

Compare Source

Nearly a year ago, we released Timefold Solver 1.0 for Java, the first step on our journey to rid the world of wasteful planning. Today, the journey continues as we announce Timefold Solver for Python!

In this first Beta release, we give the Python ecosystem access to Timefold Solver and all of its features. We invite you to try out our new Python quickstarts and let us know what you think. Do you like the APIs? Does it integrate well with your Python projects? How's the performance? We need your feedback!

Timefold Solver for Python will move out of Beta once we've heard back from enough of you. While in Beta, we reserve the right to change APIs and to add or remove functionality based on user feedback. Once we leave Beta, we will provide the same backwards compatibility guarantees as with the Java solver.

And speaking of the Java solver, we haven't forgotten about it either. In this release, we've been mostly fixing bugs and making small tweaks here and there. Going forward, we've got plenty of interesting things in store for the Java and Python solvers, as they will evolve together from now on.

How to use Timefold Solver in Java or Kotlin

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

With Maven or Gradle, add the ai.timefold.solver : timefold-solver-core : 1.11.0 dependency in your pom.xml to get started.

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 1.11.0)
to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.

v1.10.0: Timefold Solver 1.10.0

Compare Source

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.
