Is Wubi still supported?

I'm a Windows user who is dipping their toes into the Linux pool. I heard Ubuntu is a good distro for newbies, and I was interested in Wubi.exe because I could try Ubuntu without committing. However, the most recent version of Wubi is 12.10, and (at the time of this question) Ubuntu is now on 15.04. Is Wubi still even supported? Should I just get another hard drive and do a full install?
