Thanks for the upgrade, but,
"As soon as a download is started, can be used as an alternate source for others even though the download is not completed yet."
What if I don't want to share that file back out, just my own hand picked list?
"When a mismatch happens during downloading the file can now be automatically removed and restarted again"
What if I have 600MB of a file and it decides there is a "mis match" and starts over, can't you simply save this with some sort of tag like (1) (2) like I have seen around
"Sends out alternate locations which should not be tried"
What? Why not just list all the bad addresses on the net and really go crazy.
"Won't send full headers when short on bandwith"
Are your headers getting that big? Try a shorter "Server: Gtk-Gnutella (date, make, model, serial number, kitchen sink)"
