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.
