WP 5.8 should roll out today
I will not be updating right away as a huge chunk of the new FSE (Full Site Editing) code is rolling into the core.
I expect we will hear a LOT of screaming about sidebars breaking over this.
That’s why WP released the Classic Widgets plugin months ago, and most of us will need it.
But, if you have the most recent Genesis update of 3.3.4, they fixed it already.
Note: it may take a while to be rolled out to all sites so just hold off complaints and screams until folks have a chance to see what actually changed.
