The big news in this one is better link finding. It used to be that if you wanted to find the third link called "download" and you had a bunch of "download" links, you were outta luck. Now, you can just do:
$agent->follow_link( text => "download", n=>3 );
There's also a find_link() method that just returns the link without having to actually follow it. Finally, there's now a submit_form() method that wraps up all the field-setting and button-clicking into one handy-dandy wrapper function.
Thanks to Uri for lots of help with these...
