“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/…” 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.
It brings practical refinements for your editing workflow. You can now add custom CSSCSSCascading Style Sheets. to individual blocks, and the Image 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. shows aspect ratio controls for wide and full alignments. List View gets more useful with full block titles and actual content displayed for list items. The release also stabilizes viewport-based block visibility and pattern editing, plus adds focal point controls for fixed Cover backgrounds and text column support for Paragraphs.

Custom CSS Support for Individual Blocks
Gutenberg 22.5 brings custom CSS support for individual block instances, letting you write styles that target specific blocks without affecting others of the same type. A has-custom-css class is automatically added in both the editor and frontend for dynamic blocks, making your custom styles easier to manage. If you’ve been working around this limitation with extra wrapper blocks or global CSS, your workflow just got simpler. (73959, 74969)
Image Block: Aspect Ratio Control for Wide and Full Alignment
The Image block now shows aspect ratio controls when you choose wide or full alignment. Previously, aspect ratio options only appeared for default-aligned images, a limitation when designing hero sections or full-width layouts. Now you can lock in your preferred proportions regardless of alignment, giving you more consistent control over how images display across different screen sizes (74519)
List View Improvements
Two enhancements make List View considerably more useful in this release. You’ll now see full block titles instead of truncated labels, and List Items display their actual content rather than generic “List Item” text. When you’re navigating complex documents with nested lists, these small changes make a real difference—you can finally tell your list items apart at a glance (74798, 74794)
Other Notable Highlights
Cover Block: Focal point picker for fixed backgrounds: You can now set a focal point even when using fixed/parallax backgrounds (74600).
Paragraph Block: Text column support: Paragraphs can now flow into multiple columns directly via block supports (74656).
Navigation: Submenus always open option: A new toggle lets you keep submenus permanently expanded rather than requiring hover/click (74653).
In-editor revisionsRevisionsThe WordPress revisions system stores a record of each saved draft or published update. The revision system allows you to see what changes were made in each revision by dragging a slider (or using the Next/Previous buttons). The display indicates what has changed in each revision. (initial implementation: Early groundwork for viewing revisions directly in the editor, though without “diffing” yet (74771).

Announcements 📢
Nominations for CoreCoreCore is the set of software required to run WordPress. The Core Development Team builds WordPress. Team Reps 2026
The nomination process for Core Team Representatives for 2026 is over. The current Team Reps are putting together the nominations, then a poll will be opened for voting. It will stay open for two weeks.
The discussion section of the agenda is for discussing important topics affecting the upcoming release or larger initiatives that impact the Core Team. To nominate a topic for discussion, please leave a comment on this agenda with a summary of the topic, any relevant links that will help people get context for the discussion, and what kind of feedback you are looking for from others participating in the discussion.
I’d like to mention I have posted a detailed progress update for the Client Side Media feature on the tracking issue. The summary is: last week we landed the wordpress/worker-threads package, which unlocks running VIPS directly in a worker thread. This means the feature can now be tested. Also: the final 7 pre-betaBetaA pre-release of software that is given out to a large group of users to trial under real conditions. Beta versions have gone through alpha testing in-house and are generally fairly close in look, feel and function to the final product; however, design changes often occur as part of the process. PRs are nearly ready for review.
The main thing I need support on is code reviews and testing!
The meetings are currently at a difficult time for me to attend, i’m happy to answer questions a bit later if i am not able to join.
Any topic can be raised for discussion in the comments, as well as requests for assistance on tickets. Tickets in the milestone for the next major or maintenance release will be prioritized.
Please include details of tickets / PRs and the links in the comments, and indicate whether you intend to be available during the meeting for discussion or will be async.
This proposes merging the WP AI Client into WordPress CoreCoreCore is the set of software required to run WordPress. The Core Development Team builds WordPress. for WordPress 7.0.
WP AI Client is developer infrastructure: a provider-agnostic 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. for WordPress code to call generative AI models via a consistent interface, with WordPress integrations for HTTPHTTPHTTP 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. transport, event handling, caching, credentials, and a browser-friendly REST/JSJSJavaScript, a web scripting language typically executed in the browser. Often used for advanced user interfaces and behaviors. layer.
Providing this foundation, in collaboration with the Abilities API that is already part of Core, will make WordPress ready for AI, both as a consumer and as a tool.
This merge does not ship any AI providers or automatically enable AI calls. Without explicit configuration and explicit calling code, WordPress will not send prompts or data to any external service. Site owners will be able to install plugins to enable usage of specific AI providers, built on top of this foundation.
Purpose & Goals
Goals
Provide a stable, provider-agnostic AI client foundation in Core, with seamless integration with the Abilities API
Reduce duplicated SDKs/settings pages by centralizing common infrastructure (transport, auth storage, prompt invocation, access controls).
Enable plugins to detect availability and gracefully disable AI features when no model is configured.
Non-goals
No bundled credentials or providers.
No end-user “AI assistant” UIUIUser interface in core.
No product-level experiences standardized in this merge (those remain pluginPluginA plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party/ecosystem territory for now, e.g. AI Experiments plugin).
Proposed Scope
PHPPHPThe web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher API + Prompt Builder – A WordPress-friendly API to construct prompts and invoke model capabilitiescapabilityA capability is permission to perform one or more types of task. Checking if a user has a capability is performed by the current_user_can function. Each user of a WordPress site might have some permissions but not others, depending on their role. For example, users who have the Author role usually have permission to edit their own posts (the “edit_posts” capability), but not permission to edit other users’ posts (the “edit_others_posts” capability).. The underlying PHP AI Client will be bundled as an external library, while the WordPress specific wrapper code will become a direct part of Core.
Provider/model abstraction – A consistent interface so hosts/site owners can choose providers via plugins, and plugins that use AI can remain vendor-neutral.
Discoverability – Plugins can dynamically enable AI features, based on detecting whether any configured model on the site is able to respond to the relevant prompt(s).
WordPress HTTP integration – Transport aligned with WP HTTP conventions and WP_Error behavior.
Credentials management in wp-adminadmin(and super admin) – Admin UI/storage for provider credentials, used across plugins.
REST endpoints + JavaScriptJavaScriptJavaScript or JS is an object-oriented computer programming language commonly used to create interactive effects within web browsers. WordPress makes extensive use of JS for a better user experience. While PHP is executed on the server, JS executes within a user’s browser. https://www.javascript.com/. API – A REST-backed JS API for browser contexts (wp-admin/editor use cases).
Simple control mechanism for prompt execution – A filterFilterFilters 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. allows allowing or disallowing certain prompts or prompt configurations, or even AI use in general.
Security, Privacy, Performance
Security: REST/JS execution must remain capabilitycapabilityA capability is permission to perform one or more types of task. Checking if a user has a capability is performed by the current_user_can function. Each user of a WordPress site might have some permissions but not others, depending on their role. For example, users who have the Author role usually have permission to edit their own posts (the “edit_posts” capability), but not permission to edit other users’ posts (the “edit_others_posts” capability).-gated; secrets must not leak via REST/script data/logging.
Privacy: no outbound AI calls by default; calls only happen via explicit configuration + explicit invocation.
Performance: minimal footprint when unused; admin-only work should avoid affecting typical frontend requests.
Call for Feedback and Testing
Feedback is welcome via comments on this proposal or on the Trac ticket which has been opened for this change.
In particular, feedback is needed for:
Is the REST/JS surface area and capability model appropriate for long-term support?
Any missing core requirements for transport, errors, or credential storage?
As of now, there is no pull request yet. Please follow the Trac ticket to be notified when a pull request has been opened. Here are the steps you will need to follow for testing:
Apply the core PR (install a test build or utilize the WordPress Playground instance from the PR) and confirm the admin credentials UI is access-limited.
Configure a provider (or install/register a provider integration as needed).
