WordPress has postponed the release of its 7.0 Release Candidate 1 (RC1), originally slated for March 19th, citing unresolved concerns around performance, image optimization, and package size. This delay shifts the RC1 launch to March 24th at 15:00 UTC.
Real Time Collaboration performance and Client-side Media image optimization are among the enhancements requiring further attention before RC1 can be finalized. Developers also raised questions about the release package size during preparations, leading to the decision to extend the timeline. Quality assurance remains the priority as the team works to resolve these issues.
Despite this adjustment, the overall schedule for WordPress 7.0 remains unchanged. The delay applies solely to RC1, with all other milestones expected to proceed as planned. Contributors @4thhubbard, @chaion07, @ellatrix, @desrosj, @courane01, and @marybaum have been credited for their proofreading and review efforts during this critical phase.
Why This Delay Matters for Developers
Real Time Collaboration and Client-side Media features are cornerstone updates that promise to redefine workflows for content creators and developers alike. Real Time Collaboration, akin to Google Docs functionality, depends on seamless performance to avoid disrupting multi-user editing environments. Similarly, Client-side Media optimization aims to enhance image handling directly in the browser, reducing server overhead and improving load times.

The decision to delay RC1 underscores the complexity of implementing these features at scale. Developers relying on WordPress 7.0 for upcoming projects should monitor these adjustments closely to ensure compatibility and performance expectations align.
What To Do
- Plugin Developers: Test your plugins against the latest beta version of WordPress 7.0 to identify potential issues early.
- Theme Designers: Prepare for Real Time Collaboration and Client-side Media optimizations by reviewing theme dependencies and media handling workflows.
- Site Operators: Stay informed about the 7.0 release schedule and evaluate whether these new features align with your site’s operational requirements.
