= Changes in 2.2.1 =

  Jun 2, 2011 - version 2.2.1

    * Bug fixes

      * For Lighttpd + PUT/POST support, do not send a request using chunked
        encoding when IO respond to :size, File for example.

        - There is no need to send query with Transfer-Encoding: chuncked when
          IO respond to :size.
        - Lighttpd does not support PUT, POST with Transfer-Encoding: chuncked.
          You will see that the lighty respond with 200 OK, but there is a file
          whose size is zero.

        LIMITATION:
          timeout occurs certainly when you send very large file and
          @send_timeout is default since HTTPClient::Session#query() assumes
          that *all* write are finished in @send_timeout sec not each write.

        WORKAROUND:
          increment @send_timeout and @receive_timeout or set @send_timeout and
          @receive_timeout to 0 not to be timeout.

        This fix is by TANABE Ken-ichi <nabeken@tknetworks.org>. Thanks!

      * Allow empty http_proxy ENV variable. Just treat it the same as if it's
        nil/unset. This fix is by Ash Berlin <ash_github@firemirror.com>.
        Thanks!

      * Check EOF while reading chunked response and close the session. It
        raised NoMethodError.

    * Changes

      * Updated trusted CA certificates file (cacert.p7s and cacert_sha1.p7s).
        CA certs are imported from
        'Java(TM) SE Runtime Environment (build 1.6.0_25-b06)'.

      * Changed default chunk size from 4K to 16K. It's used for reading size
        at a time.

= Changes in 2.2.0 =

  Apr 8, 2011 - version 2.2.0

    * Features
      * Add HTTPClient#cookies as an alias of #cookie_manager.cookies.

      * Add res.cookies method. It returns parsed cookie in response header.
        It's different from client.cookie_manager.cookies. Manager keeps
        persistent cookies in it.

      * Add res.headers method which returns a Hash of headers.
        Hash key and value are both String. Each key has a single value so you
        can't extract exact value when a message has multiple headers like
        'Set-Cookie'. Use header['Set-Cookie'] for that purpose.
        (It returns an Array always)

      * Allow keyword style argument for HTTPClient#get, post, etc.
        Introduced keywords are: :body, :query, and :header.
        You can write
          HTTPClient.get(uri, :header => {'X-custom' => '1'})
        instead of;
          HTTPClient.get(uri, nil, {'X-custom' => '1'})

      * Add new keyword argument :follow_redirect to get/post. Now you can
        follow redirection response with passing :follow_redirect => true.

      * [INCOMPAT] Rename HTTPClient::HTTP::Message#body to #http_body, then
        add #body as an alias of #content. It's incompatible change though
        users rarely depends on this method. (I've never seen such a case)
        Users who are using req.body and/or res.body should follow this
        change. (req.http_body and res.http_body)

    * Bug fixes

      * Reenable keep-alive for chunked response.
        This feature was disabled by c206b687952e1ad3e20c20e69bdbd1a9cb38609e at
        2008-12-09. I should have written a test for keep-alive. Now I added it.
        Thanks Takahiro Nishimura(@dr_taka_n) for finding this bug.
