minor issue but when updating any plugin from github and not WordPress.org with https://github.com/afragen/git-updater following warnings exists from php-compatibility-checker in /wp-admin/update.php. When updating from WordPress.org then the warnings doesn't exist. Don't know how Premium plugins will behave, but could have the same issue.
