Fix for bug 45918: the old password field on the userprefs page is now used to log you back in if you try to change your password with cookies turned off, which avoids the confusing login screen after entering your new password in which you used to have to enter your old password one more time in order to let it set your new password (yes, it used to be as confusing as that just sounded :)
