All these new things, especially the faster speeds are awesome, however, those who make blocks with ACF Pro will get a nasty surprise with WP 6.5, unless this bug is fixed - waiting for the devs. to call this a feature of course...

So far with the first 2 beta versions of WP 6.5, ACF Blocks are only displayed in the editor in Preview mode. Those who want to use in Edit or Auto modes are out of luck. WP Engine knows about this, and who knows if this is going to be fixed by March 26 - this is a huge setback !

BTW, the fonts feature are fine with hybrid themes, obviously not classic, as the Site Editor is required to access that feature.
