WordPress 7.0 Drops Real-Time Collaboration: What Developers Need to Know Before May 20

WordPress 7.0 Drops Real-Time Collaboration — Release Still On for May 20

In a significant last-minute decision, WordPress lead developer Matt Mullenweg has officially removed Real-Time Collaboration (RTC) from the WordPress 7.0 release. The announcement came on May 8, 2026 — just 12 days before the scheduled May 20 launch — sending ripples through the developer community.

Why Was RTC Pulled?

According to the official Make WordPress Core post, Mullenweg cited concerns around:

  • Surface area — the feature introduced too many new code paths for a stable release
  • Race conditions — edge cases where simultaneous edits could cause data conflicts
  • Server load — performance concerns under sustained polling load across diverse hosting environments
  • Memory efficiency — the current implementation was not memory-efficient enough for shared hosting environments
  • Recurring bugs from fuzz testing — automated testing continued to surface reliability issues

The decision was described as “difficult, especially given the amount of work that has gone into the feature,” but was made “in service of shipping a stable and reliable WordPress 7.0 release.”

What the Host Testing Data Showed

Prior to the removal decision, eight hosting environments submitted RTC performance data between April 29 and May 4. The analysis revealed that the custom-table-with-transients storage strategy was the clear winner — approximately 52% faster than the RC2 baseline (post-meta approach). However, the data also exposed a pathological failure mode on one no-cache shared environment where dispatch latency exceeded 26ms — several times worse than any other strategy.

This instability across diverse hosting tiers was a key factor in the removal decision.

What This Means for WordPress 7.0

The good news: WordPress 7.0 is still on track for May 20, 2026. The release schedule remains unchanged. The removal of RTC actually clears the path for a cleaner, more stable launch. Other headline features remain intact:

  • WP AI Client API
  • Connectors API
  • WordPress Playground MCP Server
  • Gutenberg Phase 3 improvements

What Happens to Real-Time Collaboration?

RTC is not dead — it’s deferred. The WordPress core team has committed to:

  • Continuing development of RTC as a feature plugin or via the Gutenberg plugin
  • Using the custom-table-with-transients storage strategy as the foundation for future iteration
  • Broader testing across more hosting environments before targeting a future release

Developers who have already been building with RTC in mind can continue testing via the Gutenberg plugin. The core team noted that existing RTC code paths will remain available for testing — just not bundled in the WordPress 7.0 core release.

Gutenberg 23.1 Also Ships This Week

Alongside the RTC news, Gutenberg 23.1 was released on May 7, 2026, bringing several notable additions:

  • Parallel thumbnail uploads — significantly faster bulk image uploads
  • New @wordpress/ui primitives: Drawer and Autocomplete components
  • Experimental Image Editor with freeform cropping for Image and Site Logo blocks
  • Custom Taxonomies management screen (experimental) — create and manage taxonomies without PHP
  • New @wordpress/grid package — a DashboardGrid component with drag-to-reorder and resize handles
  • Classic Block hidden from inserter (experiment) — existing instances still work, but new insertions are blocked

Developer Takeaways

If you’re preparing for the WordPress 7.0 upgrade (launching May 20), here’s what to focus on:

  1. Remove any RTC-specific code from your plugins or themes if you were building against the RC2 implementation
  2. Test against RC3 (released May 8) — this is effectively a “new Beta 1” without RTC
  3. Review the Gutenberg 23.1 changelog for new component APIs that may affect your blocks
  4. Watch for RC4 (scheduled May 14) — this will be the true final release candidate

Key Takeaway: The removal of RTC from WordPress 7.0 is a responsible call that prioritizes stability over features. With the May 20 release date holding firm, developers now have a clearer picture of what’s shipping — and what to prepare for.
