Release Date 27th August 2026

• 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
