(07 May)](https://make.wordpress.org/core/2026/05/07/whats-new-in-gutenberg-23-1-07-may/)󠁿 **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/](https://wordpress.org/gutenberg/) 23.1? (07 May)** “What’s new in Gutenberg…” posts (labeled with the [#gutenberg-new tag](https://make.wordpress.org/core/tag/gutenberg-new/)) are posted following every Gutenberg release on a biweekly basis, showcasing new features included in each release. As a reminder, [here’s an overview](https://make.wordpress.org/core/2020/05/20/ways-to-keep-up-with-full-site-editing-fse/) of different ways to keep up with Gutenberg and the Editor. ![](https://make.wordpress.org/core/files/2025/07/gb-21-0-whats-new-1024x512.png) What’s New In Gutenberg 23.1? Gutenberg 23.1 has been released and is [available for download](https://wordpress.org/plugins/gutenberg/)! 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 blockBlock Block 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. 1.

[Contributors](https://make.wordpress.org/core/2026/05/07/whats-new-in-gutenberg-23-1-07-may/#contributors) ## **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](https://github.com/WordPress/gutenberg/pull/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](https://github.com/WordPress/gutenberg/pull/76690)) * **`Autocomplete`**, a low-level form primitive for combobox-style inputs. ([#77642](https://github.com/WordPress/gutenberg/pull/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](https://github.com/WordPress/gutenberg/pull/77194)) * **`Dialog`**, **`AlertDialog`**, and **`Drawer`** now support sticky headers and footers when their content scrolls vertically. ([#77559](https://github.com/WordPress/gutenberg/pull/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](https://github.com/WordPress/gutenberg/pull/77452)) ## Other Notable Highlights * **Custom Taxonomies management (Experiment). **An experimental UIUI User 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 PHPPHP The 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](https://github.com/WordPress/gutenberg/pull/77497), [#77524](https://github.com/WordPress/gutenberg/pull/77524), [#77657](https://github.com/WordPress/gutenberg/pull/77657), [#77697](https://github.com/WordPress/gutenberg/pull/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](https://github.com/WordPress/gutenberg/pull/77479), [#77537](https://github.com/WordPress/gutenberg/pull/77537), [#77540](https://github.com/WordPress/gutenberg/pull/77540), [#77585](https://github.com/WordPress/gutenberg/pull/77585), [#77641](https://github.com/WordPress/gutenberg/pull/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_inserter` filterFilter Filters are one of the two types of Hooks [https://codex.wordpress.org/Plugin_API/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](https://github.com/WordPress/gutenberg/pull/77747), [#77838](https://github.com/WordPress/gutenberg/pull/77838), [#77840](https://github.com/WordPress/gutenberg/pull/77840), [#77845](https://github.com/WordPress/gutenberg/pull/77845), [#77911](https://github.com/WordPress/gutenberg/pull/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 APIAPI An 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](https://github.com/WordPress/gutenberg/pull/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](https://github.com/WordPress/gutenberg/pull/77631), [#77669](https://github.com/WordPress/gutenberg/pull/77669), [#77980](https://github.com/WordPress/gutenberg/pull/77980), [#77966](https://github.com/WordPress/gutenberg/pull/77966)) ## Changelog ### Features * Upload Media: Enable concurrent sideload uploads.

If you are running "trunk", then you are on the latest revision. are currently allowed or if only RTC-related changes should be committed. [@westonruter](https://profiles.wordpress.org/westonruter/) clarified that trunk is still frozen, except for 7.0-specific fixes that get back-ported, and testing commits. - [@spacedmonkey](https://profiles.wordpress.org/spacedmonkey/) said they would hold off committing any performance-related changes for now and asked others to pingPing The act of sending a very small amount of data to an end point.

Users might say something along the lines of “Ping me when the meeting starts.” them if anything needs review or commit. - [@westonruter](https://profiles.wordpress.org/westonruter/) added that [@pbearne](https://profiles.wordpress.org/pbearne/) already has a few PRs for testing changes that could be moved forward for commit now, though not performance-related. - [@pbearne](https://profiles.wordpress.org/pbearne/) mentioned that there are more PRs to come. * [@westonruter](https://profiles.wordpress.org/westonruter/) shared that there is about a 10% regressionregression A software bug that breaks or degrades something that previously worked. Regressions are often treated as critical bugs or [blockers](https://make.wordpress.org/core/page/5/?output_format=md#blocker). Recent regressions may be given higher priorities. A "3.6 regression" would be a bug in 3.6 that worked as intended in 3.5. in TTFB in WordPress 7.0 compared to 6.9, based on benchmarking noticed by [@mukesh27](https://profiles.wordpress.org/mukesh27/).

WordPress requires PHP 7.4 or higher processing slowing things down, but no single cause has stood out yet. * [@westonruter](https://profiles.wordpress.org/westonruter/) also shared ticketticket Created for both bug reports and feature development on the bug tracker. [#65165](https://core.trac.wordpress.org/ticket/65165), which was recently opened, about script modules depending on classic scripts. [@westonruter](https://profiles.wordpress.org/westonruter/) noted that this is related to performance because it can reduce the amount of scripts loaded on the page thanks to dynamic imports, which are non-blocking, and mentioned that the ticket had just come in and had not yet been reviewed in depth. * [@westonruter](https://profiles.wordpress.org/westonruter/) further pointed out ticket [#64696](https://core.trac.wordpress.org/ticket/64696), which focuses on improving the scalability of real-time collaboration via HTTPHTTP HTTP is an acronym for Hyper Text Transfer Protocol. HTTP is the underlying protocol used by the World Wide Web and this protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. polling and its impact on persistent post caches, noting that things seem to have gone a bit quiet on that ticket. ## **Performance Lab PluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.

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/](https://wordpress.org/gutenberg/) and WordPress coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.. Keeping it accurate and up-to-date as the editor evolves is an ongoing challenge. Recently, a detailed Core Blocks reference section was proposed for the Handbook— providing structured APIAPI An 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. documentation for every blockBlock Block 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. shipped in Gutenberg. The approach was to auto-generate these pages directly from each block’s `block.json` file, the single source of truth for a block’s attributes, supports, and metadata. The initial pull request ([#77350](https://github.com/WordPress/gutenberg/pull/77350)) was merged but subsequently reverted ([#77590](https://github.com/WordPress/gutenberg/pull/77590)) due to insufficient community discussion before landing. That feedback was valid, and this post is the next step: bringing the proposal to the wider community before moving forward. The updated proposal is in PR [#77612: Docs — Auto-generate per-block API reference pages from block.json](https://github.com/WordPress/gutenberg/pull/77612). ## The problem Understanding how a core block works today means reading its source code directly. A block is defined by attributes, supports, context, selectors, and parent/child relationships — but none of these are documented in context for any individual block. To learn about a specific block, a developer has to read its block.jsonJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML. file — which shows the values but does not explain what they mean — and then separately hunt through the general documentation to understand each property. Per-block documentation with contextual links to each concept would close that gap entirely. The same problem affects LLMs: without documented context for each property, they have to parse source files to infer semantics, spending more tokens and filling context unnecessarily. This is important for AI-assisted creation of templates, template parts, patterns, and other block editor content. Most of this detail already exists in the codebase. If it can be surfaced automatically, there’s no good reason to leave it buried. ## The proposed solution The proposal introduces an **automated pipeline** that generates per-block API reference pages by reading each block’s `block.json` at build time. This means: * Every block shipped in Gutenberg automatically gets a documentation page reflecting its current attributes, supports, selectors, and other metadata. * Keeping docs in sync becomes a byproduct of keeping block.json accurate — which developers already do. * The Block Editor Handbook gains a canonical, always-current API reference for all core blocks. The generated docs would live at paths like: `developer.wordpress.org/block-editor/ reference-guides/core-blocks/[block-category]/[block-name]` and would look like this: ### README.md per block in the repository A key part of the proposal is that documentation is generated into a README.md file inside each block’s source directory — for example, `packages/block-library/src/ paragraph/README.md`. This follows the same convention already established for component documentation, where `gen-components-docs` generates a `README.md` inside each component’s directory at `packages/components/src/{component}/README.md`. Having documentation live next to the code has a specific benefit: it allows **hand- written narrative and auto-generated API reference to coexist in the same file**. Generated content is wrapped in token delimiters (`
