Release notes for 5/28/14

This is an extremely complicated subject, and counter intuitive to people who think that standards are a good idea and should be followed... maybe start with a statement like this?
"Web browsers support videos in different formats; however, not all browsers support all video formats." 
and maybe close with a call to action for the course staff, like
"You can use course FAQ or your Course Info page to recommend the browsers that work best with your videos to your students."
