These “Core Editor Improvement…” posts (labeled with the #core-editor-improvement tag) are a series dedicated to highlighting various new features, improvements, and more from Core Editor related projects.
Over the last few Gutenberg releases, a few more deeply technical changes have unlocked some big improvements across the experience of exploring and using site editing. The result is a smoother experience of exploring block themes, making changes, and entering the Site Editor. The work mentioned here addresses key areas of feedback that have been raised over the months and years with the FSE Outreach Program, particularly around revisions and the ability to preview themes. While what’s shared here is available in the Gutenberg plugin (in some cases as an experiment with block theme previewing), please help explore and test these features to ensure they each make it into the official WordPress 6.3 release come August 8th, 2023.
Rely on revisions for templates, template parts, and styles
