New Blocks in WordPress 5.4

Social Icons Block

This new block lets users link to social media and other popular websites by using those sites’ logos. Initially called Social Links, Social Icons were an experimental feature in Gutenberg 6.5 but held out of WordPress 5.3. Since then, the Block Variations API has progressed to the point that Social Icons in Gutenberg 7.5 are much simpler and more stable – and ready for merge in WordPress 5.4.

This reimplementation is a breaking change in the way Social Icons are saved (see details). Only sites that have run the Gutenberg plugin since September are potentially concerned. 

In WordPress 5.4, the core block editor will not recognize any Social Icons blocks built before Gutenberg 7.5.

There are two ways to deal with this:

  • (Recommended method) Manually migrate any content with old Social Icons. Here’s how: load a post in the block editor (Gutenberg 7.5 or higher) and save it. The block editor will automatically update its contents. 
  • Keep the Gutenberg plugin installed after upgrading to WordPress 5.4. The plugin will give you manual backwards compatibility for the old Social Icons.

Buttons Block

This new block is a collection of buttons, because authors often need to use several at a time (for instance: download and read more buttons).

The buttons block shows each button as an individual button-block child of the Buttons block. You won’t be able to insert a button block outside Buttons, but your existing button blocks will work the way they always have.

In case you were using the button block as part of a template or a system that automatically inserted a button block, you’ll want to use the Buttons block with a nested button instead.

Plus, here’s some good news: you won’t need to migrate your existing button blocks. They’ll just work — again, as they always have.
