WordPress 4.9.4 maintenance release

WordPress 4.9.3 has been presented yesterday, today we already have WordPress 4.9.4 to be the newest version. Just after releasing 4.9.3 they obviously found one severe bug which avoided the automatic update to the newer version via backend. This was also the only bug which has been fixed within this new release and this is why 4.9.4 came out so fast after 4.9.3
