+# Allow Unfiltered ACF Content
+
+See https://www.advancedcustomfields.com/blog/acf-6-2-5-security-release/
+
+- Starting in 6.2.7 ACF will strip unsafe content from `the_field`, `the_subfield`, and shortcodes
+- We can test early by applying a filter
+- We can disable the filtering for trusted fields via a filter
+
+This plugin will enable the chanmges before they are released via `add_filter( 'acf/the_field/escape_html_optin', '__return_true' );`  
+
+This is done to see what will occur on sites.
+
+If we have trusted content that we don not want ACF to filter, we can exclude by filtering one field or shortcode at a time.
