This should be really bigger news! Although I don't use KDE at all, Kile is the best editor for Latex, I have tried. The developers released 5 beta versions before, which never gave me any problem. 11 Days ago, kile 2.1 was finally released, here is the release announcement.
I love how simple Kile is, although it is full with goodies and options. I love how it is out of the way when you want it. I tried contributing to Gummi-latex editor. But eventually, I found it useless.
I love the VIM mode in Kile, and I wish it was possible in some GTK+ Editor. Yeah, I know I can use vim-latex-suite. But I am too lazy to learn it :-). So, I use vim for all other programming, and Kile for Latex.
So, bottom line, I really recommend to download and install latest Kile!
