Just like the planet lately, we're turning up the heat! In this release, we improve solver performance across the board - Constraint Streams, Value Ranges, Shadow Variables, everything gets a speed bump.
But most importantly, we have significantly improved our underlying metaheuristics so that in those few cases where the solver would previously get stuck, it no longer does. Not only are you going to get your solutions faster, they will also be even better in quality.
Finally, we have significantly refactored our documentation, in preparation for the rollout of the Timefold service. Stay tuned for more information!
(And forgive the rudimentary release notes we publish this time around. The release automation stumbled a bit, but it'll be back next time.)
