Timefold Solver 1.21.0

With our usual monthly cadence, we bring you another fresh batch of features, bugfixes and small improvements.

How to use Timefold Solver

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

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 1.21.0)
