**Add fields on demand.**
The ACF field builder allows you to quickly and easily add fields to WP edit screens with only the click of a few buttons! Whether it's something simple like adding an “author” field to a book review post, or something more complex like the structured data needs of an ecommerce site or marketplace, ACF makes adding fields to your content model easy.

**Add them anywhere.**
Fields can be added all over WordPress including posts, pages, users, taxonomy terms, media, comments and even custom options pages! It couldn't be simpler to bring structure to the WordPress content creation experience.

**Show them everywhere.**
Load and display your custom field values in any theme template file with our hassle-free, developer friendly functions! Whether you need to display a single value or generate content based on a more complex query, the out-of-the-box functions of ACF make templating a dream for developers of all levels of experience.

**Any Content, Fast.**
Turning WordPress into a true content management system is not just about custom fields. Creating new custom post types and taxonomies is an essential part of building custom WordPress sites. Registering post types and taxonomies is now possible right in the ACF UI, speeding up the content modeling workflow without the need to touch code or use another plugin.

**Simply beautiful and intentionally accessible.**
For content creators and those tasked with data entry, the field user experience is as intuitive as they could desire while fitting neatly into the native WordPress experience. Accessibility standards are regularly reviewed and applied, ensuring ACF is able to empower as close to anyone as possible.

**Documentation and developer guides.**
Over 10 plus years of vibrant community contribution alongside an ongoing commitment to clear documentation means that you'll be able to find the guidance you need to build what you want.

Please see the [blog post for this release for more information.](https://www.advancedcustomfields.com/blog/acf-6-2-5-security-release/) Thanks to Francesco Carlucci via Wordfence for the responsible disclosure
* Security - ACF now warns via an admin message, when upcoming changes to `the_field` and `the_sub_field` may require theme changes to your site to avoid stripping unsafe HTML. Please see the [blog post for this release for more information](https://www.advancedcustomfields.com/blog/acf-6-2-5-security-release/)
* Security - Users may opt in to automatically escaping unsafe HTML via a new filter `acf/the_field/escape_html_optin` when using `the_field` and `the_sub_field` before this becomes default in an upcoming ACF release.
