There are bug fixes, specifically the crashing bug for some win9x/me systems. There are also a few added features, the main ones of use are ctrl-b, ctrl-i, and ctrl-u shortcuts for bold, italic, and underline.
There was also a bug in the friends/friendsof dialog that i fixed, that surprisngly.. no one mentioned to me, but i ran across it on my own so its all good. Anyway, I would recommend downloading the new version..
I hope you like it.
