icloud mail format changed recently

A couple of days ago I noticed some changed functionality on icloud mail.

1. I used to be able to select multiple mail items to delete by using the control key and selecting messages. That is not working now.
2. I can't find the print icon.
3. Program font has changed.

Little things, but frustrating. Did I unknowingly change some setting, or did the program get an upgrade that changed the user interface?
