 * Plugin Name:       ACF Blocks V2 Iframe Compatibility
 * Plugin URI:        https://advancedcustomfields.com
 * Description:       Forces the WordPress block editor to not use the iframe canvas, if there's an ACF v2 block on the site. This plugin is intended to give site owners more time to migrate to the iframe experience provided by core. It should not be used permanently.
 * Version:           1.0.0
 * Requires PHP:      7.4
 * Author:            ACF
 * Author URI:        https://advancedcustomfields.com
 * Text Domain:       abic
 * Requires Plugins:  advanced-custom-fields-pro

 * Cap ACF's default block version for blocks registered without an explicit
 * ACF block version.
 *
 * ACF bumps its default to 3 on WordPress 7.1+, which changes the type of any
 * block registered without acf_block_version set. Users of this plugin want to
 * stay on the pre-7.1 defaults without touching their block registrations, so
 * mirror them: PHP-registered blocks (acf_register_block_type) get v1, JSON-
 * registered blocks (block.json) get v2. Blocks that explicitly opt into v3
 * are unaffected; the filter default only applies when no version is set.
 *
 * @param integer     $version The default block version ACF would have used.
 * @param array|null  $context The block settings/metadata array (unused).
 * @param string|null $source  Registration source: 'php', 'json', or null on
 *                             ACF versions that don't pass this arg — in which
 *                             case both paths fall through to v2.
