v2.0.0

2.0.0 (2026-10-29)

⚠ BREAKING CHANGES

• form.update, control updates, and generated array actions now throw when they change the number of rows of another mounted generated array. Use that array's actions or form.array(path).reconcile instead.
• an ArrayItem slot move to an index outside the array throws a RangeError instead of being ignored. The tester throws RangeError instead of TypeError for an invalid index, and tester.setValue on a field that the UI cannot edit returns an uncommitted transition.
• the devtools Features tab lists only configured features and shows "This form configures no optional features." when there are none.
• the Material UI preset i18n keys addItem, removeItem, moveItemUp, and moveItemDown are now arrayAdd, arrayRemove, arrayMoveUp, and arrayMoveDown. Item callbacks get { index, position } instead of a number.
• react-hook-form 7.81.0 or newer is required.
