AdvancedCustomFields/acf 6.8.4

Advanced Custom Fields v6.8.4

on GitHub

Release Date 10th June 2026

• Security - ACF AJAX field handlers now validate that the request nonce was created for the expected field type
• Enhancement - ACF PRO now satisfies plugin dependencies declared against advanced-custom-fields, so plugins requiring ACF can activate when only ACF PRO is installed
• Enhancement - acf_inline_toolbar_editing_attrs() now accepts a return_array argument that returns the attributes as an escaped array suitable for use with wp_get_attachment_image()
• Fix - acf_form() with 'post_id' => 'new_post' and a fields list of field names no longer fatal errors when acf_form_head() runs before WordPress's main query is built
• Fix - Multiple acf_form() calls wrapped inside a single outer <form> tag with one submit button no longer silently drop field values, post_title, or post_content from the non-last forms
• Fix - Duplicating a V3 block with identical attributes no longer displays corrupted preview content in the duplicate
• Fix - Switching between tabs containing WYSIWYG fields no longer leaves the admin menu pinned against a shorter page, which could lock page scroll
