This is a hotfix release for Timefold customers. Please update if all of the following applies to you:

• You use list variables with unassigned values,
• you use multi-threaded solving,
• and you use construction heuristics.

If any one of the above doesn't apply to you, you do not need to update to Timefold Solver 1.8.1 and can wait for the regularly scheduled release next month.
