react-hook-form

Changed

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

• Improve performance of getValues by avoiding unnecessary shallow copies

• 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

• Form sending a text/plain body for a text/plain content type

• createFormControl copying the errors prop instead of writing into it

• useForm resetting resetOptions when removed from props

• createFormControl handling falsy values correctly in _getDirty and resetField

• unregister dropping the field's rules when keepValue keeps only its value

• useForm clearing errors when the errors option is removed or set to undefined

• useFieldArray dropping a validation result once the array has changed

• 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

• 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
