I'm sure i've read before that you don't currently advertise it... but I think it would be a great idea to have an "Expected Due Date" of the next version and perhaps an upcoming changes.txt - might stop a few posts about the same bugs again and again.
Also, now that mIRC happily sends information to http://www.mirc.com:80/. perhaps a "There is an update available" messagebox (once per version) popup on load? or even automatic update that would update the needed files rather than the whole installation stuff.
