My Service host (dot5 hosting) has Agora cart 4.0k-3 version installed, which I used to almost complete setting up my store. I've noticed a few differences on the forums here between what is discussed and what I actually see in my version, which has caused several hours of frustration at times. Is there much advantage to upgrading to the 4.0k-4b version? If so, what are the files that are different between the two versions? I have DL'ed the latest version on my PC, and uploading is not a problem, I just don't want to upload a file that I already modified and have to do it over again.
