[Koha] Database upgrade funniness

I just did a fetch on my install of master and got the upgrade db page. But this time the page said something funny: "We are upgrading from Koha 3.05.00.004 to 3.05.00.004, you must update your database" There is no difference in those versions and nothing was actually changed (at least not according to the screen). Is there a typo that was pushed? Or did I have a problem in my system? Nicole
