ACF 5.9.2 Release

Experimental block preloading

Since releasing our PHP framework for custom block type development back in version 5.8, we have been inundated with positive feedback, success stories and enhancement requests. It’s clear that the main “gripe” with a server-side visual editor is exactly that – it requires an HTTP request to fetch each block’s HTML, making for a slow and sometimes painful experience whilst editing a Post.

We’re excited to announce we have a solution for this, and invite you to help test it out! To enable block preloading and experience a “zero delay” Gutenberg page loading experience, please add the following code to your wp-config.php to enable the fix:

define('ACF_EXPERIMENTAL_PRELOAD_BLOCKS', true);

👉 You can post your results and follow our progress via this GitHub issue.
