One improvement aims to solve site speed problems caused by Largest Contentful Paint (LCP), a metric that measures how long it takes to load the largest image or text block. Site speed poses a problem to website owners because it affects how visitors experience your site. Google has also gone on record to say that site speed is a ranking factor. In addition to speed, WP 6.3 offers new features and editor enhancements.
