Thanks for sharing these information with us! I’ve already prepared all my Wordpress sites.
Meh… I have three more days to procrastinate 
Success! I just thought I’d drop a note to say that I’ve updated all my Pinegrow sites to WordPress 6.4, using a combination of the compatibility plugin and upgrading the projects with PG 7.8, and everything worked as planned.
I’ve had issues with some other non-Pinegrow sites, and chatter on the internet makes it sound like quite a few plugins are causing headaches with WP 6.4, so keep that in mind and make sure you test thoroughly and have good backups before upgrading.
