react-hook-form

Changed

• Improve performance of Form by reading control from context to avoid unnecessary re-renders

• Simplify multipart content-type header filtering

• Align form-level validation error types

Fixed

• useFieldArray not registering array rules again after reset

• setValue not updating field array rows when a parent object is set

• createFormControl keeping a newer change's error when an older isValid pass settles

• validate treating an empty message array as valid

• reset releasing keepIsValid on the next field change or field array operation

• register only emitting the progressive required attribute when the rule is on

• createFormControl dropping the async result of a field unregistered while it validates

• createFormControl supporting null-prototype objects in setValue

• Form handling case-insensitive and parameterized multipart encType

• createFormControl ignoring a stale NaN or Invalid Date validation result

• Settle submit state when validation throws

• Form letting fetch set the multipart boundary for a multipart content-type header

• createFormControl ignoring a stale built-in validity result after reset

• useForm running the initial validity check when a child subscribed first

• reset keeping retained fields disabled

• useForm re-enabling the form when the disabled option is removed

• formState producing a new validatingFields reference when it changes

• validateField validating the stored value of Controller fields with a DOM ref

• useForm resetting progressive option when removed from props

• cloneObject copying plain objects that have a constructor key

• useFieldArray reindexing row fields when the array has rules

• Form matching JSON content types case-insensitively

• deepEqual comparing keys as own properties instead of via in

• register keeping select options picked before the form is ready

• Report isReady to useFormState mounted with the form

• useFieldArray revalidating array operations after submit in onBlur mode

• getDirtyFields handling null or undefined form values when clearing a field

• setValue updating isDirty when shouldDirty fills a field array

• delayError flushing the delayed error on blur when blur also validates

• useWatch using the new defaultValue when the watched name changes

• deepEqual comparing sparse array lengths

• Form sending a url-encoded body for a url-encoded content type

• deepEqual comparing empty null-prototype objects by content

• Enforce numeric zero maxLength

• register not adding an array row when registered without a value

• Form matching Content-Type header names case-insensitively

• trigger recomputing preserved isValid after reset

• useFieldArray unregistering on unmount unless a parent array is reindexing

• setValue notifying field arrays so their rows follow the new values

Changed

• Improve performance of watch, subscribe, scoped subscriptions, dirty field checks and form state fan-out

• Reduce bundle size

Fixed

• Fields named after Object.prototype members not being marked as touched on blur and setValue

• Dirty values extraction for fields named hasOwnProperty

• cloneObject dropping the length of sparse arrays

• cloneObject failing on objects with a null prototype

• Form options removed from props on re-render not being reset

• remove() mishandling duplicated indexes and mutating the indexes passed in

• useFieldArray unregistering fields while a parent array reindexes

• Input edited before the form is ready being overwritten

• useWatch not updating watched objects after an <Activity> subtree reconnects

• useWatch preferring its own defaultValue over form defaultValues for array names

• reset without values and keepDefaultValues setting isDirty to true

• Controller blur validation not working after reset

• watch reading a stale shouldUnregister option when a field registers

• Native validation reading a stale shouldUseNativeValidation option when stopping at the first error

• Form values stored under a ref key not being compared correctly

• setError, clearErrors and remaining error updates not producing a new errors reference

Changed

• Add optional @types/react peer dependency

Fixed

• validateField calling setCustomValidity on refs that don't implement it under native validation

• Form-level validate running a stale function instead of the latest one

• Form-level validation leaving stale errors after a successful re-validation

• Form-level validation running more than once per traversal

• Stale validation results (resolver, built-in, form-level validate) being applied after reset in onChange and handleSubmit

• Pending delayError timers for nested paths not being cancelled when a parent validates clean or is reset via resetField

• getValues(names, { dirtyFields }) returning every row of a field array instead of only the marked entries

• Field array touched state not being re-indexed when touchedFields is not subscribed

• useFieldArray emitting touchedFields in form state updates when unnecessary

• Stale field array root error not clearing once an array operation satisfies the rule

• useFieldArray marking the form dirty when the array default is null

• Dirty state lingering for rows removed from a field array

• setValue with shouldValidate not revalidating deps

• setValue with shouldValidate not triggering validation for a field array root

• Validation rules removed from register options at runtime still being applied

• useController validating required against the input value instead of the controlled value

• isValid not recomputing when the errors prop is emptied

• getFieldState(name, formState) with a resolver after reset()
