WordPress Release: 6.2.5

TL;DR

WordPress 6.2.5 is a maintenance release that focuses on improving test reliability and updating npm packages. This release addresses issues with external HTTP tests by using images from the WordPress.org CDN instead of WP.com to avoid inconsistencies caused by on-the-fly image compression. It also updates editor npm packages to their latest patch versions and makes adjustments to build tools to ignore certain sourcemap warnings. Additionally, a test for Gutenberg plugin installation was removed as the plugin is no longer compatible with WordPress 6.2.

Upgrade Recommendations
