The Core team publishes a monthly update that is worth reviewing to understand the status features planned for upcoming versions of the Gutenberg plugin and when you can expect those capabilities to be available in Core. With the upcoming Beta 1 deadline for WordPress 5.6, we strongly recommend taking a few minutes to stay current and have a solid plan for what to do when 5.6 rolls out.
Highlights from this update include 5.6 Beta 1 Preparation, Global Styles & Editor focused APIs, the Widget Screen, and Full Site Editing. At this point, we don’t see Full Site Editing making the 5.6 cut.
