*Release Date 27th August 2026*
* [View Release Post](https://www.advancedcustomfields.com/blog/acf-6-8-9-released/)
* Enhancement – ACF Blocks registered via `acf_register_block_type()` or `block.json` without an explicit version now default to v3 on WordPress 7.1 or later. Blocks that specify a version continue to use the version they declare, and the default can be customized via the `acf/blocks/default_block_version` filter
* Enhancement – ACF Blocks v3 now supports a `renderPreview` option in `block.json`. Setting `”renderPreview”: false` shows a placeholder with the block’s icon, title, and an “Edit Block” button in the editor instead of rendering the block’s template as a live preview. The block continues to render normally on the front-end, and legacy v2 blocks combining `”mode”: “edit”` with `”supports”: { “mode”: false }` are automatically migrated when upgraded to v3
* Fix – Inline editable fields in ACF Blocks V3 no longer require a second click before they can be edited
* Fix – Radio buttons now appear correctly in ACF admin screens
* Fix – Image and Gallery fields no longer reject SVG uploads when the Safe SVG plugin is active
