Hi, I installed Community Answers 3.1 on my site in Jan.   I see that now version 4.2.5 is avialble.  How do I upgrade form 3.1 to 4.2.5?  I would liek to do it automatically from within Joomal, but cannot find a means to do so.    Must I download 4.2.5 and install manually?  How do I keep my current questions and settings?

Thanks
