In the response to the discussion during the Dev Chat, I'm doing a first pass to keep WordPress packages up to date in the WordPress 5.8 release cycle. See https://github.com/WordPress/wordpress-develop/pull/1176 for more details. Props youknowriad, aristath, andraganescu. See #52991. Built from https://develop.svn.wordpress.org/trunk@50761 git-svn-id: http://core.svn.wordpress.org/trunk@50370 1a063a9b-81f0-0310-95a4-ce76da25c4cd
