Update to 1.22:

1.22        Fri Mar  2 00:05:57 CST 2007

[INTERNALS]
Added new tests.

Added Perl::Critic changes and a perlcriticrc file.

1.21_04     Sat Oct  7 21:35:42 CDT 2006

[FIXES]
*   $mech->content( type => 'text' ) was not freeing memory.  Thanks to
    Cat Okita for finding it.

[INTERNALS]
*   Made the order of parms to $mech->content() not relevant.

1.21_03     Sat Oct  7 01:21:46 CDT 2006

[THINGS THAT MAY BREAK YOUR CODE]
*   The methods $mech->form() and $mech->follow() have been removed.
    They've been deprecated since 1.10, which was released in Feb 2005.

[ENHANCEMENTS]
*   I'm trying to nail down what seems to be a memory leak on long-running
    Mech programs.  I'm stringifying URI::URL objects wherever I can.

[INTERNALS]
*   No longer uses UNIVERSAL.

[ENHANCEMENTS THAT MAY BREAK YOUR CODE]

*   The $mech->stack_depth() setting had no way to say "don't cache any
    pages at all".  How silly!

    Now, if you set $mech->stack_depth(0), no history of pages will be kept.
    In the past, it would mean "Keep all pages."  This means that if \ 
you want
    to set it to keep all pages, set it to some ridiculously large number.

[DOCUMENTATION]
*   The docs previously refered to Compress::Gzip instead of Compress::Zlib.

1.21_01 Mon Sep 18 17:18:43 CDT 2006

[ENHANCEMENTS]
*   If Compress::Zlib is installed, gzipped content is now
    accepted and transparently decoded. No additional syntax needed!
    This should save time and bandwidth in a number of cases.
    (Mark Stosberg)

*   Added a put() method.  It also calls a subfunction called
    _SUPER_put that will be removed once LWP::UserAgent supports put().
