How to create new "Versions" and rename of versions in the Zephy Squad Cycle Summary Window

Hello.

I'm trying to create a new VERSION in Zephyr Squad Test Cycle overview, so that i can add test cycles to it. Do any of you people know how to create a new "version" in the Cycle Summary Window ? Or is it created somewhere else and just selected in the Cycle Summary Window ?

Second. I've got some existing VERSION's in the Cycle Summary Window which i would like to rename. How to to this?
