I’ve been around the block since WordPress 4.x, and I’ve seen enough “major” releases to know when a version is just a coat of paint versus a structural overhaul. With the arrival of WordPress 7.0 RC1, we are officially in the structural overhaul territory. This isn’t just about blocks anymore; it’s about the underlying plumbing that will handle AI and multi-user collaboration for the next decade.
The first Release Candidate for WordPress 7.0 dropped recently, and while it’s tempting to hit “Update” on everything, you need to be smart about it. We are looking at over 134 updates since Beta 5, including some heavy-duty APIs that could easily break a poorly configured site. If you’re managing mission-critical WooCommerce stores or high-traffic blogs, read this before you touch your server.
The AI Connectors Screen: Structural Plumbing
One of the headline features in WordPress 7.0 RC1 is the new AI Connectors screen. For years, we’ve been hacking together API calls to OpenAI or Anthropic using various third-party plugins. Core is finally providing a standardized way to register these providers. This is a massive win for portability; if you want to switch from one LLM provider to another, you won’t have to refactor every single block or function that relies on AI.
There is even support for registering non-AI providers through the same interface. If you’re a developer, you should be looking at the official Connectors API documentation to see how your plugins can hook into this. We previously discussed the AI Client merger, and RC1 is the realization of that effort.
Real-Time Collaboration and the RTC Constant
Real-Time Collaboration (RTC) is finally opt-in by default in this release candidate. However, don’t expect it to just “work” without some configuration if you’re on a custom stack. There’s a new constant you need to be aware of if you want to manage this via wp-config.php. It’s a classic race condition nightmare waiting to happen if your server polling intervals aren’t tuned correctly.
/**
* Enable or Disable Real-Time Collaboration in WordPress 7.0
*/
define( 'WP_ALLOW_COLLABORATION', true );
// Senior Tip: Watch your server resources.
// RTC uses increased polling intervals which can spike CPU on low-end shared hosting.I’ve seen plenty of sites crawl to a halt because of aggressive admin-ajax polling. RC1 addresses this by allowing you to toggle session notifications and increasing the default polling intervals to keep things sane.

How to Safely Test WordPress 7.0 RC1
If you’re still logging into SFTP to upload zip files, we need to talk. The most efficient way to test WordPress 7.0 RC1 is via WP-CLI. It’s clean, it’s fast, and it’s repeatable. Just make sure you’re doing this on a staging environment—never, and I mean never, run an RC on a live production site unless you enjoy emergency midnight debugging sessions.
# Update to the latest Release Candidate via WP-CLI
wp core update --version=7.0-RC1Alternatively, you can use the WordPress Playground if you just want to poke around the new Command Palette (try ⌘K or Ctrl+K in the admin bar) without setting up a local server. It’s a great way to see how the new “Client Side Media” behaves when it’s restricted to plugin-only mode.
Look, if this WordPress 7.0 RC1 stuff is eating up your dev hours, let me handle it. I’ve been wrestling with WordPress since the 4.x days.
Final Takeaway for Developers
The jump to 7.0 is as much about cleaning up legacy bottlenecks as it is about new features. Seeing OPCache stats finally added to Site Health > Info > Server is a small but vital win for those of us obsessed with performance. The final release is scheduled for April 9, 2026. Use the next few weeks to refactor your themes, test your activation hooks, and ensure your site doesn’t blow up when the “Hard Freeze” hits. Ship it—but test it first.
