What’s new in Gutenberg 16.3? (26 July)

“What’s new in GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/…” posts (labeled with the #gutenberg-new tag) are posted following every Gutenberg release on a biweekly basis, showcasing new features included in each release. As a reminder, here’s an overview of different ways to keep up with Gutenberg and the Site Editor project (formerly called Full Site Editing).

Gutenberg 16.3 has been released and is available for download!

16.3 is largely a maintenance release. This means that lots of bugs have been fixed behind the scenes, though this release does see some enhancements to patterns in addition to plenty of other minor improvements. Read on to find out how working with patterns has been improved.

This release consists of 180 pull requests authored by 54 contributors, including three new contributors! 🎉

‘Focus mode’ editing for patterns

When editing template parts in the Site Editor the interface is in ‘focus mode’. However ‘focus mode’ was not previously available when working with patterns. This release enables ‘focus mode’ editing for patterns. (52427)

Sticky headerHeader The header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes. bar on Patterns page

Previously on the Patterns page the header bar containing the search box scrolled out of view when you scrolled down the page. Other pages, such as the Templates page, did not have this problem and the header bar remained in view while scrolling the page. Gutenberg 16.3 fixes this and the header bar now remains firmly fixed to the top of the screen when you scroll the Patterns page. (52663)

Rename, duplicate, and delete patterns

Patterns now have a drop-down menu, accessed via the three dots, that allows you to rename, duplicate, and even delete patterns easily. Performing these operations has now been made much easier than it previously was.. (52270)
