[7.81.0] - 2026-07-05

Added

• FieldArray component built on useFieldArray for controlled field-array rendering

Fixed

• clearErrors changing the name value from form.subscribe
• reset triggering subscribe with the latest name instead of undefined
• setValues leaving stale elements behind when shrinking a field array
• flatten preserving Date values as leaf nodes
• useFieldArray min length validation error changing location in the errors object
• useController not reflecting a cleared parent object in controlled fields

Security

• Harden unset() against prototype-path traversal (__proto__ / constructor / prototype), matching the existing set() guard

Performance

• Improve re-render with useFieldArray reset
