Security Improvement: To improve server compatibility, requests to the iThemes updater servers would automatically downgrade from https to http when https connections failed. This update removes the automatic downgrade. If your server cannot make outbound https connections, you can re-enable the downgrade capability by adding the following define in your site's wp-config.php file:
define( 'ITHEMES_ALLOW_HTTP_FALLBACK', true );
Bug Fix: Version Management compatibility with further changes in WordPress 5.6.
