[7.86.0] - 2026-08-22

Added

• Type-safe getErrors method

Performance

• Improve createFormControl
• Improve clone object check
• Avoid cloning values in unregister without subscribers

Fixed

• Field array update leaving stale errors and touched state at the updated index
• flatten discarding File and Blob values instead of treating them as leaf nodes
• validateField not passing the field error to setCustomValidity when criteriaMode is all
• hasValidation treating falsy but valid values (min: 0, max: 0, minLength: 0, maxLength: 0, required: '') as no validation
• setValue targeting a nested leaf not notifying a Controller registered on a field array item root
• setValues not updating fields registered under an object or array value
• useWatch returning a stale value on name change when the new value is null
• unregister inverting keepDirty when broadcasting isDirty
