WWW-Mechanize 1.00

on Perl CPAN

I figure it's about time we hit 1.00, and this version seems
like a good place to do it, because of the potential breakage
described below...

[THINGS THAT WILL BREAK YOUR CODE]

• Header handling has changed. There is no more package variable
  %headers that holds all the headers to be added. They are
  now added on a per-object basis.
  

If you were adding a header with add_header(), and the code
relied on that header still being set later on in a later
instance of the class, that code will now break, because the
later instance won't have the header set.

[ENHANCEMENTS]

• You can now prevent a header from being sent by adding it with
  an undef value, as in:

  $mech->add_header( Referer => undef );

[FIXES]

• Now correctly adds Accept-Encoding to all requests that need it.
  

[INTERNALS]

• Added new $mech->_modify_request($req) method to do all the
  HTTP header modification before the actual request gets
  sent off. Subclasses are able to override it if they want.

• Removed the unused Compress::Zlib stuff.
