replaced by the
[hackney_mimetypes](https://github.com/benoitc/hackney_lib/blob/master/doc/hackney_mimetypes.md)
module. It makes content-type detection a little more efficient. In the
process the functions `hackney_util:content_type/1` and
`hackney_bstr:content_type/1` has been removed. You should now use the
function `hackney_mimetypes:filename/1` .

  it as a stream.
- bump hackney_lib version to 0.2.2

0.10.0 - 2013/12/29
-------------------

- improve multipart handling: With this change, we can now calculate the
  full multipart stream content-length using `hackney_multipart:len_mp_stream/2` .
- add `hackney:setopts/2` to set options to a request when reusing it.
- add `hackney:send_reques/3` to pass new options to a request.
- add the `{stream_to, Pid}` setting to a request to send the messages
  from an asynchronous response to another PID.
- fix `Host` header: some server do not comply well with the spec and
  fail to parse the port when they are listening on 80 or 443. This
change fix it.
- fix: make sure we are re-using connections with asynchronous
  responses.

### Breaking changes:

- All messages from an async response are now under the
  format `{hackney_response, Ref, ... }` to distinct hackney messages
from others in a process easily.
- You can only make an async response at a time. Ie if you are are doing
  a persistent request (reusing the same reference) you will need to
pass the async option again to the request. For that purpose the
functions hackney:send_request/3 and hackney:setopts/2 have been
added.
- multipart messages have changed. See the documentation for more
  information.

------------------

0.9.0 - 2013/12/19
------------------

- add support for cookies: There is now a `cookie`
option that can be passed to the request. It can be a sinle cookie or a
list of cookies. To parse cookies from the response a function `hackney:cookies/1` has
been added. It return all the cookies as a list of [{Key, Value}].

- optimization: send body and headers together when it is possible
- fix release handling

0.8.3 - 2013/12/07

  timeout return `{error, connect_timeout}`

0.8.0 - 2013/12/02
------------------

major release. With this release the API will not evolve much until the
1.0 release sometimes in january.

- breaking change: hackney now return a reference instead of an opaque record. The
  information is maintained in an ETS table. The same reference is now
used for async response requests.
- breaking change: `stream_body_request/2` and `stream_multipart_request/2` functions has
  been renamed to `send_body/2` and `send_multipart_body/2` .
- breaking change: remove `hackney:close_stream/1` function. You only need to
  use `hackney:close/1` now.
- breaking change: rename `hackney:raw/1` function to
  `hackney:cancel_request/1`.
- breaking change: the hakney pool handler based on dispcount is now
  available in its [own repository](https://github.com/benoitc/hackney_disp) so hackney doe  not depends on dispcount.
- fix: canceling and closing a request now make sure the async response
  process is killed.
- fix: make sure we pass a `Transfer-Encoding: chunked` header when we
  send a body without content-length.
- fix: make sure the client is correcly reconnected when we reuse a
  reference.

0.7.0 - 2013/11/22
------------------
