I have no idea why they changed the version number to 2.4.0r instead of 2.4.0pro, - but I don't think it means very much.

As for the options, you are missing, - they're still in the code, and I have already seen and used them in 2.4.0r.

I had a couple of lock ups with the cvs code, which usually occur after running limewire for 6-12 hours. Seen anything like that on your computer with 2.4.0r, yet?
