Releases: TimefoldAI/timefold-solver
Timefold Solver Community Edition 1.1.0
We are proud to announce the general availability of Timefold Solver Community Edition 1.1.0!
The highlights of this release include:
- Significant improvements to constraint matching performance.
- Several important bugfixes.
- Documentation improvements and other minor tweaks.
To ensure Constraint Streams process data correctly in all cases, we unfortunately had to sacrifice some solver performance. (See bug #186.)
Some use cases may see score calculation speeds drop by 5 % on average.

How to use Timefold Solver
To see Timefold Solver in action, check out the quickstarts.
With Maven or Gradle, just add the ai.timefold.solver : timefold-solver-core : 1.1.0 dependency in your pom.xml to get started.
You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 1.1.0) to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.
