What’s new in GutenbergGutenbergThe 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/ 23.1? (07 May)
“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.
This release introduces two new experiments aimed at managing content inside the editor. A Custom Taxonomies management screen lets you create and edit taxonomies from Settings, and a new Media Editor brings better image manipulation into the WordPress media flow. Outside of the editor, the @wordpress/ui package gains new compound primitives, Drawer and Autocomplete, alongside overlay polish. Other changes include an experiment to hide the classic blockBlockBlock is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. from the inserter, parallel thumbnail uploads, an early developer preview of @wordpress/grid, and a batch of real-time collaboration reliability fixes.
Faster image upload finalization
Sideload requests for an image’s generated thumbnail sizes used to run sequentially within a single upload. They now run in parallel up to the existing concurrency limit, which speeds up upload completion. (#75888)
The speed improvement is most noticeable on bulk uploads via the Gallery block, large images, and slower connections.
@wordpress/ui primitives
The @wordpress/ui package gains two new primitives and polish across overlay components.
Two new compound primitives ship in 23.1:
Drawer, for slide-in side panels and bottom sheets. (#76690)
Autocomplete, a low-level form primitive for combobox-style inputs. (#77642)
Other polish across overlay components:
The Dialog component gains a new Description subcomponent, plus several tweaks to its spacing and typography to align it better with Drawer. Additionally, its Backdrop only dims the page when the Dialog is modal. (#77194)
Dialog, AlertDialog, and Drawer now support sticky headers and footers when their content scrolls vertically. (#77559)
All overlays *.Popup subcomponents gain a new portal prop which, combined with new optional *.Portal subcomponents, allows for better customization of the portaling behavior. (#77452)
Other Notable Highlights
Custom Taxonomies management (Experiment). An experimental UIUIUser interface for managing custom taxonomies inside WordPress adminadmin(and super admin). With the “Content types: manage custom taxonomies” experiment enabled, a new Taxonomies screen lets you create, edit, activate or deactivate, and delete taxonomies without writing PHPPHPThe web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher. Enable it via Gutenberg → Experiments → “Content types: manage custom taxonomies”, then visit Settings → Taxonomies. (#77497, #77524, #77657, #77697)
Image Editor with Freeform Cropper (Experiment). A new experimental Image Editor modal for image manipulation in the Block Editor. The modal enables freeform cropping and other manipulation tools for Image and Site Logo blocks. To test it out, enable the experiment via Gutenberg → Experiments → Media Editor Modal, then, in the editor, click on the Crop icon in the block toolbar. (#77479, #77537, #77540, #77585, #77641)
Disable Classic Block from the inserter. The “Disable TinyMCE” experiment was refocused and landed to disable the Classic block from the inserter. The reason for the change is that removing TinyMCE everywhere broke too many existing flows. Existing Classic block instances continue to work normally, since the change only affects the inserter. A new wp_classic_block_supports_inserterfilterFilterFilters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. was introduced to allow controlling this behavior. (#77747, #77838, #77840, #77845, #77911)
@wordpress/grid package (developer preview). A new @wordpress/grid package introduces DashboardGrid, a two-dimensional grid component with drag-to-reorder and resize handles for dashboard-style surfaces. The package is in active development, and the APIAPIAn API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. is expected to evolve in upcoming releases. (#77562)
Real-time Collaboration reliability improvements. Several fixes improve RTC reliability and load behavior. The “Connection Lost” dialog no longer appears when a page registers more sync rooms than the server’s per-request cap. A client/server size-check mismatch that could reject large Yjs updates has been corrected. When two offline users reconnect and both push compactions, they no longer end up in a divergent state. Sync observers also attach after the persisted CRDT document is hydrated, which avoids redundant block re-parsing during editor load. (#77631, #77669, #77980, #77966)
