Under The Hood WordPress Changes

WordPress 5.6 has arrived with tons of features and improvements targeted towards developers. The following are some of the most significant under the hood changes.

WordPress 5.6 continues the second phase of the three-step plan to upgrade the core jQuery bundled with WordPress. Theme and plugin developers relying on jQuery are already testing their code for any issues so it is not likely to affect large number of users. (See details)

The new 5.6 release also includes REST API Batch Framework for making a series of REST API calls in one request to the server. (See details)

A new action wp_after_insert_post is also available in WordPress 5.6. It allows theme and plugin developers to run custom code after a post and its terms and meta data have been updated. (See details)

WordPress 5.6 has replaced older-style PHP type conversion functions with type casts. (#42918)

WordPress 5.6 also introduced the ability to merge WP_Error objects into one another. This would allow developers to add more than one item of data to the WP_Error object. (#38777)

We hope this guide helped you explore what’s new in WordPress 5.6. We are particularly excited about the new default theme and the improvements made to the block editor.
