[ANN] mechanize 2.4 Security Fix Released

* http://mechanize.rubyforge.org
* https://github.com/tenderlove/mechanize

The Mechanize library is used for automating interaction with websites.
Mechanize automatically stores and sends cookies, follows redirects,
and can follow links and submit forms. Form fields can be populated and
submitted. Mechanize also keeps track of the sites that you have visited as
a history.

=== Changes

* Security fix:

  Mechanize#auth and Mechanize#basic_auth allowed disclosure of passwords to
  malicious servers and have been deprecated.

  In prior versions of mechanize only one set of HTTP authentication
  credentials were allowed for all connections. If a mechanize instance
  connected to more than one server then a malicious server detecting
  mechanize could ask for HTTP Basic authentication. This would expose the
  username and password intended only for one server.

  Mechanize#auth and Mechanize#basic_auth now warn when used.

  To fix the warning switch to Mechanize#add_auth which requires the URI
  the credentials are intended for, the username and the password.
  Optionally an HTTP authentication realm or NTLM domain may be provided.

  See http://mechanize.rubyforge.org/Mechanize.html#method-i-add_auth for complete
  details.

* Minor enhancement
  * Improved exception messages for 401 Unauthorized responses. Mechanize now
    tells you if you were missing credentials, had an incorrect password, etc.
