What are the key differences between the movie Edge of Tomorrow and the original book?

Movie: Main protagonist's name is Cage
Book: Main protagonist's name is Keiji

Movie: Mimics are comprised of the Omega and the Alphas
Book: Mimics are comprised of the Nexus and Antennae

Movie: Killing an Alpha causes the time loop to reset
Book : Killing either the Nexus or the Antennae can cause the time loop to reset

Movie: Only Cage is a looper, Rita used to be a looper
Book: Both Keiji and Rita are loopers

Movie: Getting to the Omega and killing it will end the time loop and stop the alien race
Book: The Nexus needs to be killed only after all the Antennae have all been killed

Movie: The ending of the Movie, Cage kills the Omega, and is reset back to an earlier time, the entire alien race is dead, no one knows that Cage did it, the world goes back to how it was a day prior, Rita is alive, happy ending.
Book: In the final time loop, once they have eliminated all the Antennae, Rita attacks Kaji telling him that they have been in the loop so long that they have become like the Antennae, unless one of them dies, killing the Nexus will only cause the loop to reset. Keiji kills Rita and is crowned the Hero Of The War.

This website lists a mere five, but considering that those five are basically the core of the movie...

1. Major Bill Cage and Private Keiji Kiriya are entirely different
2. Rita Vrataski from All You Need is Kill would bitch slap Emily Blunt
3. The Mimics are much scarier in the movie
4. The War, and our world are very different
5. The endings are drastically different
