WordPress 6.6.2 introduces 26 bug fixes, including an important one that resolves a CSS issue affecting site appearance. Fifteen fixes address the WordPress core, while eleven focus on the Gutenberg block editor.
Maintenance Release – CSS Specificity
WordPress maintenance releases generally consist of minor updates intended to fix issues introduced by new features in the last major update, in this case, version 6.6.
This maintenance release includes a fix for a feature called CSS specificity that was introduced in WordPress 6.6.
CSS is the code that determines the appearance of a web page in terms of colors, sizes, margins, and spaces. Specificity refers to which style belongs to a web page element (like a section of a page or something more granular). CSS Specificity is a set of rules in the WordPress core that determines which CSS property applies when there is ambiguity. The purpose of CSS Specificity was initially to make it simple for theme developers to override WordPress core styles with their own.
However, it was discovered that the implementation of CSS Specificity introduced several issues that significantly affected the appearance of web pages.
WordPress 6.6.2 fixes this issue, so publishers who’ve had issues should consider updating.

This maintenance release contains 15 fixes to the WordPress core and 11 fixes to the Gutenberg block editor.
Examples of fixes in the Core included in the maintenance release:
