[DEPRECATIONS]
- The %WWW::Mechanize::Headers hash is officially deprecated.
It will be removed pretty soon. I'm not sure what the
replacement will be, but it won't be a package-level hash.
[ENHANCEMENTS]
- The submit() method is no longer an alias for click("submit"),
because some forms don't have a button called "submit".
In fact, some may not have any buttons at all if they're
JavaScript-controlled.
[FIXES]
- RT #2056: $agent->field() wasn't returning proper input field,
because of an incorrect call to the underlying HTML::Form.
