6.5.7
Release Date 28 Aug 2025
Features
- Flexible Content layouts can now be renamed in the post editor, giving content editors better clarity when managing layouts.
- Flexible Content layouts can now be disabled, preventing them from rendering on the frontend without needing to delete their data.
- Flexible Content layouts can now be collapsed and expanded in bulk for faster content editing.
- Editing a Flexible Content layout now highlights the layout being edited, making it easier to identify.
- The Date and Date Time Picker fields can now be configured to default to the current date.
- Custom Icon Picker tabs now work correctly when used inside an ACF Block.
- Duplicating a Field Group no longer causes a fatal error when using Russian translations.
- ACF classes no longer use dynamic class properties, improving compatibility with PHP 8.2+.
- Field group metabox collapse and expand buttons are no longer misaligned in the post editor.
- HTML is now escaped from field validation errors and tooltips.
- Added a new source parameter to the /wp/v2/types REST API endpoint that allows filtering post types by their origin: core (WordPress built-in), scf (for SCF managed types), or other for the rest of CPTs.
Security
– Unsafe HTML in field group labels is now correctly escaped for conditionally loaded field groups, resolving a JS execution vulnerability in the classic editor.
– HTML is now escaped from field group labels when output in the ACF admin.
– Bidirectional and Conditional Logic Select2 elements no longer render HTML in field labels or post titles.
– The acf.escHtml function now uses the third party DOMPurify library to ensure all unsafe HTML is removed. A new esc_html_dompurify_config JS filter can be used to modify the default behaviour.
– Post titles are now correctly escaped whenever they are output by ACF code. Thanks to Shogo Kumamaru of LAC Co., Ltd. for the responsible disclosure.
– An admin notice is now displayed when version 3 of the Select2 library is used, as it has now been deprecated in favor of version 4.
