Update to head possible without DB upgrade?

Dear all,

Can one upgrade to the HEAD revision of filefield (which is the latest revision, I guess) without a DB upgrade? I see that filefield.install does not include any new upgrades so I assume I can safely update, right?

My Drupal-5 site is currently using the HEAD revision of 2007-04-02 (2nd April 2007), i.e., my module has revision // $Id: filefield.module,v 1.23 2007/03/30 03:20:24 dopry Exp $.

Thanks a lot for helping me!
