Release 4.0.0 2-Step Verification

fancy-announcements

This will allow announcements with richer HTML support.

an-icon-by-any-other-name

We ended up needing to use different versions of the logo for the favicon and the main logo shown on the login page. This does that, as well as generally improving the situation for the favicon.

will-the-real-announcement-please-stand-up

The team decided to take a new approach to getting announcements to work even though they will still be displayed the same way as before.

This release will provide module consumers with a material look and feel for splash screens requested by the expirychecker module.

what-about-the-phone

UI tweak for the login screen on smaller devices.
