Any updates in advance of Wordpress 5.0 (a.k.a Gutenberg?) - I feel like we need some kind of update from the MemberMouse team on this. Thanks
We test every new WordPress release against MemberMouse prior to asserting compatibility in our WordPress Compatibility article (http://support.membermouse.com/support/solutions/articles/9000020204-wordpress-compatibility).
Since Gutenberg was released we have been doing background testing and running it separately against MM without issue. Once the release candidate for 5.0 is available (currently on October 30) we will start our rounds of QA testing so that we can provide further updates as necessary prior to the full release of 5.0.
I hope this is helpful! :)
