This patch, somewhat small brings a lot to WordPress. This includes features like: - DataViews. - Customization tools like box shadow, background size and repeat. - UI improvements in the site editor. - Preferences sharing between the post and site editors. - Unified panels and editors between post and site editors. - Improved template mode in the post editor. - Iterations to multiple interactive blocks. - Preparing the blocks and UI for pattern overrides. - and a lot more. Props luisherranz, gziolo, isabel_brison, costdev, jonsurrell, peterwilsoncc, get_dave, antonvlasenko, desrosj. See #60315.
