Level Up Your WordPress 6.8 Site with These Practical Code Snippets

WordPress 6.8 is the final major release of 2025. Over the course of 2025, new features and improvements will go out in minor WordPress core releases.

One site performance feature that the 6.8 release includes is for speculative loading using the speculation rules API. The speculative loading feature has outstanding cross-browser support, and using the feature will help improve the front-end performance in most cases.

The following code snippet excludes a specific URL in this case, the cart URL from being loaded using the speculative loading feature. 

If you want to increase the eagerness of the speculative loading feature in WordPress 6.8, you can use this code snippet.

If you needed to enable menus to make them publicly accessible, you can now do this using this code snippet in the REST API in WordPress 6.8. The default behavior in the WordPress 6.8 release is that menus are not publicly accessible in the REST API on a site.

These are only some of the many helpful code snippets that apply to the new features and improvements included in the WordPress 6.8 major core release.

MainWP has a solid, easy-to-use code snippets plugin that allows code snippets to be saved and executed on connected sites.
