# PHP 8 Deprecated code

 * When declaring a function or a method, adding a required parameter after optional
   parameters is deprecated since PHP 8.0.
 * > PHP Deprecated: Required parameter $field_id follows optional parameter $type
   > in /heartbeat-control/vendor/cmb2/cmb2/includes/rest-api/CMB2_REST.php on line
   > 693
 * Need to check the code in the declaration of functions and methods and their 
   calls.

 * To the author of the plugin, this is fixed in CMB2 in the latest on github, so
   you can update your bundled copy.

 * Also of note to Mikhail, due to the way the CMB2 loader works, you can install
   the CMB2 plugin, and it will use the most recent version, fixing those issues
   in your log. [https://wordpress.org/plugins/cmb2/](https://wordpress.org/plugins/cmb2/).
