Newer programs bring more efficiency, or atleast that's why we have newer updates/patches, etc. One key example I can note is of one ultra peer who had version 4.0.1 , this is quite an old version and should be upgraded.

I completely agree with the security updates, although I disagree with the efficiency notion. Even though i havent been using limewire for the longest time, I did upgrade and such, and did happen to notice the simple trend that higher versions didnt necisarily slow down the machine more and more, it was infact the amount of files; which has been stated through out these forums numerous times.

This brings the question why does Limewire update there program as often as they do if it doesnt help the program.
