1.4.0

Response is no more a String, and the mixin is replaced by an abstract_response, existing calls are redirected to response body with a warning.
enable repeated parameters RestClient.post 'http://example.com/resource', :param1 => ['one', 'two', 'three'], => :param2 => 'foo' (patch provided by Rodrigo Panachi)
fixed the redirect code concerning relative path and query string combination (patch provided by Kevin Read)
only get and head redirections are now followed by default, as stated in the specification

The response change may be breaking in rare cases.

1.3.1

added compatibility to enable responses in exception to act like Net::HTTPResponse

a block can be used to process a request's result, this enable to handle custom error codes or paththrought (design by Cyril Rohr)
cleaner log API, add a warning for some cases but should be compatible
accept multiple "Set-Cookie" headers, see http://www.ietf.org/rfc/rfc2109.txt (patch provided by Cyril Rohr)
remove "Content-Length" and "Content-Type" headers when following a redirection (patch provided by haarts)
all http error codes have now a corresponding exception class and all of them contain the Reponse -> this means that the raised exception can be different
changed "Content-Disposition: multipart/form-data" to "Content-Disposition: form-data" per RFC 2388 (patch provided by Kyle Crawford)

The only breaking change should be the exception classes, but as the new classes inherits from the existing ones, the breaking cases should be rare.

formatting changed from tabs to spaces
logged requests now include generated headers
accept and content-type headers can now be specified using extentions: RestClient.post "http://example.com/resource", { 'x' => 1 }.to_json, :content_type => :json, :accept => :json
should be 1.1.1 but renamed to 1.2.0 because 1.1.X versions has already been packaged on Debian

new maintainer: Archiloque, the working repo is now at http://github.com/archiloque/rest-client
a mailing list has been created at rest.client@librelist.com and an freenode irc channel #rest-client
François Beausoleil' multipart code from http://github.com/francois/rest-client has been merged
ability to use hash in hash as payload
the mime-type code now rely on the mime-types gem http://mime-types.rubyforge.org/ instead of an internal partial list
204 response returns a Response instead of nil (patch provided by Elliott Draper)

All changes exept the last one should be fully compatible with the previous version.

NOTE: due to a dependency problem and to the last change, heroku users should update their heroku gem to >= 1.5.3 to be able to use this version.
