“What’s new in 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 Editor.

What’s New In Gutenberg 23.0?

Gutenberg 23.0 has been released and is available for download!

This release introduces a revisions panel for templates, template parts, and patterns (experimental), and extends the Site Editor’s Design › Identity panel with Site Title and Site Tagline fields, completing the set alongside the previously added Site Logo and Icon. Real-time collaboration gains compatibility with legacy meta boxes and a range of reliability improvements, while the block editor receives several quality-of-life refinements.

A total of 174 PRs were merged in Gutenberg 23.0, with 8 first-time contributors.

Table of contents

Enhancements

Revisions panel in templates, template parts, and patterns (experimental)

Editing a template, template part, or pattern now surfaces the same Revisions panel previously available only for posts and pages. When any of these entities has revisions, a Revisions row appears in the sidebar with access to review and restore prior versions, matching the behavior already in place for regular post types.

This is part of the ongoing Editor Inspector: Use DataForm experiment, which is progressively rolling out a unified DataForm-based inspector across all post types. Enable the experiment from Gutenberg → Experiments to try it in the Site Editor or while editing a template from the Post Editor. (#77008)

Site Title and Site Tagline in the Design › Identity panel

The Design › Identity panel — introduced in 22.8 with Site Logo and Site Icon — now also includes Site Title and Site Tagline. All four identity settings sit in a single panel, editable directly from the Site Editor without a trip to Settings → General. Because the title and tagline fields write to the same root/site entity that the Site Title and Site Tagline blocks read from, edits show up live in the editor canvas as you type. The panel uses consistent field styling across text and media controls, so the four settings read as one unified form. (#76264)

Other Notable Highlights

  • Real-time Collaboration, legacy meta box compatibility. Plugin authors can now mark individual meta boxes as RTC-compatible using a new __rtc_compatible_meta_box flag, so the presence of a legacy meta box no longer unconditionally disables collaboration. Site administrators can also apply the flag to third-party meta boxes via the existing filter_block_editor_meta_boxes hook. (#76939)

  • Real-time Collaboration, reliability. Concurrent edits to array-type block attributes — such as table rows — are now preserved when the array is restructured (#77164). A single corrupted sync update no longer crashes the whole poll cycle and disconnects every room (#76968). Gutenberg’s activation hook now honors the Core WP_ALLOW_COLLABORATION constant, giving hosts a reliable kill switch (#77084).

  • Keyboard shortcuts for moving blocks surface in tooltips. The block toolbar’s move-up / move-down tooltips now display their keyboard shortcuts. (#76992)

  • Spacing side controls re-order when unlinked. When link mode is off, the four side inputs are arranged in a more predictable order. (#66317)

  • Separator block honors the --- shortcut’s default variation. Inserting a Separator via the Markdown-style --- shortcut now applies the block’s default style variation, matching the behavior of inserting it through the inserter. (#77135)

Note for users of the Guidelines experiment

If you had the Guidelines experiment enabled in a previous release, 23.0 renames its internal identifiers from content-guidelines / content_guideline to guidelines / guideline. The rename covers the custom post type slug, REST base, meta keys, experiment flag, and Redux store. Because the experiment flag itself is renamed, it will appear disabled after updating — you’ll need to re-enable it from Gutenberg → Experiments and re-enter any previously saved guidelines. (#77147, #77223)
