The latest WordPress update, version 6.6.2, brings 26 essential bug fixes, including a crucial resolution for a CSS issue that was causing display problems on websites. Out of the 26 fixes, 15 are directed at the WordPress core, while 11 target the Gutenberg block editor.
Maintenance Release Focus: CSS Specificity Fix
WordPress maintenance releases typically address problems introduced in previous major updates, and version 6.6.2 follows this pattern. One of the most significant issues resolved in this update relates to CSS specificity, a feature first introduced in WordPress 6.6.
CSS (Cascading Style Sheets) governs the appearance of web pages by defining elements like color, spacing, and layout. CSS specificity establishes rules for which styles take precedence when multiple styles apply to a single element. The introduction of CSS specificity in WordPress 6.6 was intended to help theme developers easily override default WordPress styles with their own custom designs.
However, the initial implementation caused unintended visual issues across various websites. WordPress 6.6.2 resolves these problems, making it a highly recommended update for anyone affected by display inconsistencies.
Additional Core Fixes
In addition to the CSS specificity correction, WordPress 6.6.2 includes 15 fixes within the WordPress core, addressing the following issues:
- Template content disappearing after renaming
- Autofocus parameter not functioning correctly in the customizer
- Search functionality issues in the installed themes section
- Site Health Tool getting stuck while loading directory sizes
Gutenberg Block Editor Improvements
The release also provides 11 fixes for the Gutenberg block editor, improving its stability and functionality. Notable fixes include:
- Preventing template parts from being duplicated in non-block-based themes
- Removing unnecessary VisualEditor height adjustments to avoid canvas issues
- Fixing post editor spacing and ensuring post types without a menu icon avoid errors
Reception of WordPress 6.6.2
The initial response to this maintenance release has been positive. Members of the Dynamic WordPress Facebook Group, including administrator David McCan, have successfully deployed the update on multiple sites without encountering issues.
For publishers facing display problems or other bugs, upgrading to WordPress 6.6.2 is a smart move to ensure a smoother, more reliable website experience.
