Adds two new features:
- An
isValid
value is now returned fromuseFormContext
. - When form validation fails via an attempted submit, the first invalid input will be focused. It is also now possible to use
useField
to specify ahandleReceiveFocus
callback that will be called when an input is going to receive focus this way. This is primarily to support custom components that use hidden inputs for their value and some other ui for the "input".
