WordPress 7.0 was meant to be the Real-Time Collaboration release. Instead, as the April 2026 WordPress 7.0 developer updates show, the core team pulled it back from Release Candidate to Beta. After 14 years of watching releases ship with known bugs to hit a date, I am glad to see architectural integrity beat the calendar for once.
The delay is not a scheduling hiccup. It is a fix for a performance bottleneck, and I have seen enough race conditions in sync engines to know that a database layer you get wrong on day one is one you keep patching until 8.0. Here is what is changing and what it means for your own plugins and themes.
Why the RTC database layer failed
The first implementation of Real-Time Collaboration (RTC) used Yjs as the CRDT engine, but it stored sync data as post_meta on a hidden internal post type. Every character a user typed fired a metadata update, and every update invalidated the persistent post query caches. Put ten people in one long-form article and server load spikes to the moon.
The fix now in development gives collaboration data its own database table, which separates sync traffic from the standard WordPress post objects. I went through how these sync protocols got here in an earlier piece on WordPress 7.0 release delays.
The AI client and connectors: standardizing the glue code
The other headline item in this cycle is the WP AI Client. We have all written custom glue code to connect OpenAI or Anthropic to WordPress, and it is fragmented enough that every project maintains its own version of the same mistakes. Core is finally shipping a standard PHP library for it.
The interface is provider agnostic. If a client wants to move from ChatGPT to a local Ollama instance, that is a configuration change rather than a rewrite of your codebase. Credentials are handled separately, by the new Connectors API.
<?php
/**
* Example of using the new WP AI Client in 7.0
* Prefixing with bbioon_ as per senior standards.
*/
function bbioon_generate_content_summary( $post_id ) {
$client = wp_ai_get_client();
if ( is_wp_error( $client ) ) {
return $client;
}
$response = $client->chat( [
'messages' => [
[ 'role' => 'user', 'content' => 'Summarize this post...' ]
]
] );
return $response->get_text();
}I broke down the architecture of the library in a separate guide to the WordPress 7.0 AI Client. If you are building plugins that touch AI at all, that is the part worth your time.
Pseudo-states and viewport controls in theme.json
Styling buttons in block themes has always been awkward. Handling :hover or :focus meant leaving theme.json for custom CSS, then fighting specificity to make it stick. Gutenberg 22.8 and later support pseudo-elements in theme.json directly.
7.0 also adds viewport-based visibility controls, and they work through CSS media queries rather than removing nodes from the DOM. The markup stays in the page, so hiding a heavy block on mobile does not cost you in search. If you are carrying a third-party block visibility plugin, you may be able to drop it once 7.0 lands.
Debugging with the Playground MCP server
The WordPress Playground MCP (Model Context Protocol) server is the piece I keep coming back to. With the @wp-playground/mcp package you can wire an AI agent such as Claude straight into a local Playground instance. You tell your IDE to debug the race condition in a transient, and it executes PHP, reads the file and navigates the site to find the bottleneck. On a legacy codebase that saves real hours.
If the 7.0 migration is eating your dev hours, I can take it off your plate. I have been working with WordPress since the 4.x days.
What to do before 7.0 ships
The RTC delay is a headache for project managers and a relief for anyone who gets paged about these sites at 3:00 AM. Two things are worth doing now: move any PHP 7.2 or 7.3 sites up to 7.4 or later, and start putting the AI Client through its paces. The cycle is paused until April 17th, but nothing about that pause makes the refactor less overdue. Watch the official dev notes for the rest.
