WordPress 5.4 – “Adderley” (in honour of Nat Adderley) – will be the first major release of 2020 with a strong focus on refining the block editor.
The block editor will not only load 14% faster but also will take 51% less time-to-type for a particularly sizable post (~ 36,000 words, ~1,000 blocks).
The New Welcome Guide Modal
If you are new to WordPress, this release introduces you to the block editor with a welcome guide popup. This is just a simple slide-show that will walk through the basic information about blocks with then take you to the Block Library, and will provide a link to a block editor tutorial.
