Minor Changes

• Introduced a Prioritized Default System that ensures consistency between field metadata and form reset behavior. This change prioritizes field-level default values over form-level defaults across isDefaultValue derivation, form.reset(), and form.resetField(). This ensures that field metadata accurately reflects the state the form would return to upon reset and prevents undefined from being incorrectly treated as a default when a value is explicitly specified. (#2006)

Patch Changes

• evaluate() incorrectly treated distinct non-plain objects with no own enumerable keys (Temporal types, RegExp, getter-only class instances) as equal because the key-iteration loop vacuously succeeded. A guard now returns false for such objects, falling back to referential inequality. (#2140)

• exclude undefined from FormState errors type (427b3d9)

• Prevent synchronous validators from returning Promises (#1987)

• re-render arrays when length doesn't change but values do (#2172)
