Thanks @sebastian-moran for the reminder. I checked it and didn’t notice anything major except bugs/issues fixes and Gutenberg updates. Did you notice anything special?
Expect some regression fixes for most WordPress core branches shortly.
Well, it didn’t go as planned!!! We got a lot of sites with the Alpha version of WP 5.5.3 plus the installation of all Twenty themes from ten to twenty. Lucky, with MainWP, it was a question of minutes to remove those extra themes from more than 110 sites…
WordPress 5.5.3 release.
Core ticket which showed the alpha update issue.
