I installed cm 10.2 the other day on my att HTC one. When cm 11 becomes stable, is there any way I can get it without having to wipe my phone again?

So, if I wanted cyanogenmod 11, would I have to root?

changing from CM 10.2 to CM 11 would only require a wipe/factory reset and flash of the current rom
Shouldn't even need to factory reset from 10.2 to 11
As @Rukbat stated above, with any major version change, you should do a full wipe/factory reset. Dirty flashing KitKat on top of Jellybean is not recommended.
