I'm wanting to change the wording and add some styling to the upgrade.php page.
We have a situation where we update our codebase across multiple sites via Git - when a user logs in after the update they are greeted with the "You must update your database" message.
This is fine but we want to refine the page a little, either filtering the text or adding a script to do it the dirty way.
The problem is I don't see any hook for this page and the text is hardcoded in upgrade.php.
Any help appreciated :)
