-* UserLoginForm and UserCreateForm hooks, and AuthPlugin::modifyUITemplate, now receive a
- SpecialPage subclass instead of a QuickTemplate subclass. Hence there is no
- $template->set(), etc. The hook has access to most of the stuff that will go into the
- Login/Create form; see the documentation on HTMLForm for syntax for extra fields.
-* LoginForm class is deprecated, its state constants are now in the Login class.
