Elliot Condon's latest communication on Gutenberg - Exciting Developments Coming for ACF as 2018 Rolls On.

Elliot: Testing ACF with Gutenberg is going great. I’m happy to see how well Custom Meta Boxes are being supported in this new JS powered edit screen – everything seems to be working out of the box! The only issues are due to changed actions and filters, which will require some minor compatibility patches. As the Gutenberg project continues to develop, we will continue to test and roll out updates.
