I'm very pleased that, according to downloads, only 83% of the people using π Final Form are also using π React Final Form. That was the intent of the dichotomy between state management and view framework. Look at those babies diverge, starting in 2019! β€οΈ

π React Final Form Arrays v3.0 now has #ReactHooks support! π
Breaking changes are mostly about upgrading your dependencies.
Now those of you using field arrays can upgrade to the latest greatest π React Final Form!

π RFF v6.0.0 - To fix a part of the API that @flowtype prohibits (parse={null}), we've had to introduce a breaking change, so we've taken the opportunity to make another breaking change, to prohibit subscription changes, thus excising edge-case code from your bundle size. βοΈ

.@whereischarly Why is the first time I'm hearing about Frontier on the live stream of your @ReactEurope talk? Looks AWESOME!!
I've been waiting for someone to create another React usage of @finalformjs.

Has this ever happened to you?
You type into an input and hit β, your form is submitted without the browser ever firing the onBlur event. π« So if you are doing something, like formatting values onBlur, you're out of luck...π€¬
...unless you're using π React Final Form v5.1.0!

Released today, π Final Form 4.13.0 introduces beforeSubmit and afterSubmit callbacks for fields, enabling fields to get their matters settled (and optionally abort the submit) before the submit actually happens.
β οΈ Validation is not re-run! β οΈ

React Final Form v5.1.0 uses this callback to perform formatOnBlur, so the formatted value gets submitted. Users have been asking for this for a while.
Enjoy!

Q: What's the difference between react-final-form-hooks and the hooks introduced in react-final-form v5?
A: Both still have a place in the world. github.com/final-form/react-β¦

Before the launch of π React Final Form v5, I wanted to do a quick performance test, to see if, with hooks, it was faster or slower than v4. TLDR: It's more or less the same. Also compared to rival Formik.

π£ I've spent the past two weeks rewriting π React Final Form using hooks and rewriting *all* the tests to use π React Testing Library. It's been a great learning experience, and the library feels as robust as ever. Up to 100% coverage...hope to release sometime this week. β±
