WordPress 6.9.1

WordPress 6.9.1, released on 3 February 2026, is a short‑cycle maintenance update that follows the major 6.9 “Gene” launch in December 2025. Rather than adding new features, this point release concentrates on stabilising the core and the Block Editor by fixing forty‑nine bugs that were reported after the 6.9 release.

The most noticeable improvements relate to the Block Editor itself. A number of regressions in the editor’s user interface and in the way block‑CSS is handled have been corrected, meaning that editing posts and pages is now more reliable and less prone to unexpected layout shifts or crashes.Legacy or “classic” themes also benefit from this release. Several CSS‑loading bugs that previously affected older theme frameworks have been resolved, restoring the intended appearance for sites that continue to use these themes.

Email delivery, an essential part of many WordPress sites, received particular attention. Problems that arose with certain sendmail configurations—affecting password‑reset messages, comment notifications and other transactional emails—have been fixed, ensuring that such communications reach recipients as expected.

Another noteworthy fix concerns post navigation. An edge‑case bug that could cause infinite loops when moving between adjacent posts has been eliminated, allowing visitors to move smoothly forwards and backwards through content.

Beyond these headline areas, the update patches a variety of miscellaneous issues across the core codebase, ranging from REST‑API responses to media handling, thereby improving overall site stability and performance.

The release was a community effort involving more than eighty contributors, with core committers Aaron Jorbin and Aki Hamano leading the work. Their coordinated effort highlights the strength of the WordPress community in delivering rapid, high‑quality maintenance fixes.

Site owners can apply the update automatically from Dashboard → Updates, or manually download the package from the WordPress.org release archive. Most installations that have automatic background updates enabled will already have received the patch.

WordPress 6.9.1 cleans up the core and Block Editor after the 6.9 launch, addressing bugs that touched classic themes, email delivery, post navigation and numerous other components, and it paves the way for the forthcoming major release, WordPress 7.0, scheduled for April 2026.
