Advanced Custom Fields version 6.8.4 is now available
Patch ACF to 6.8.4 to fix Google Maps double‑encoding, Link field validation, oEmbed crashes, and WooCommerce HPOS order saving.
Patch ACF to 6.8.4 now to address the listed bugs.
Summary
Advanced Custom Fields (ACF) released version 6.8.4 on 2026-07-15, addressing a series of bugs that affected both front‑end and back‑end workflows. The update removes double‑encoding of Google Maps field values when stored in an ACF block, preventing corrupted map data in posts. In the Classic Editor, inserting a Link field no longer forces validation of unrelated required fields before the post is saved, streamlining content creation. Auto Inline Editing blocks now return empty strings instead of truthy placeholder strings for empty field values fetched from a different post, improving template rendering consistency.
ACF Blocks V2 and V3 are now protected against crashes when rendering an oEmbed field whose title begins with “[” or “{”, a common edge‑case that previously caused fatal errors. Field group location rules that lacked a location value no longer trigger PHP warnings on page load, reducing server log noise. The visual appearance of URL, Number, and Select fields has been refined for WordPress 7.0 and newer, offering a cleaner admin interface. Finally, ACF fields now correctly save on WooCommerce orders when using HPOS in compatibility mode, ensuring order metadata integrity.
