# 2.0.0

This release is largely API compatible, but makes several breaking changes.

- Drop support for Ruby 1.9.2
- Respect Content-Type charset header provided by server. Previously,
  rest-client would not override the string encoding chosen by Net::HTTP. Now
  responses that specify a charset will yield a body string in that encoding.
  For example, `Content-Type: text/plain; charset=EUC-JP` will return a String
  encoded with `Encoding::EUC_JP`.
- Change exceptions raised on request timeout. Instead of
  `RestClient::RequestTimeout` (which is still used for HTTP 408), network
  timeouts will now raise either `RestClient::Exceptions::ReadTimeout` or
  `RestClient::Exceptions::OpenTimeout`, both of which inherit from
  `RestClient::Exceptions::Timeout`. For backwards compatibility, this still
  inherits from `RestClient::RequestTimeout` so existing uses will still work.
  This may change in a future major release. These new timeout classes also
  make the original wrapped exception available as `#original_exception`.
- Unify request exceptions under `RestClient::RequestFailed`, which still
  inherits from `ExceptionWithResponse`. Previously, HTTP 304, 401, and 404
  inherited directly from `ExceptionWithResponse` rather than from
  `RequestFailed`. Now _all_ HTTP status code exceptions inherit from both.
- Rename `:timeout` to `:read_timeout`. When `:timeout` is passed, now set both
  `:read_timeout` and `:open_timeout`.
- Change default HTTP Accept header to `*/*`
- Use a more descriptive User-Agent header by default
- Drop RC4-MD5 from default cipher list
- Only prepend http:// to URIs without a scheme
- Fix some support for using IPv6 addresses in URLs (still affected by Ruby
  2.0+ bug https://bugs.ruby-lang.org/issues/9129, with the fix expected to be
  backported to 2.0 and 2.1)
- `Response` objects are now a subclass of `String` rather than a `String` that
  mixes in the response functionality. Most of the methods remain unchanged,
  but this makes it much easier to understand what is happening when you look
  at a RestClient response object. There are a few additional changes:
  - Response objects now implement `.inspect` to make this distinction clearer.
  - `Response#to_i` will now behave like `String#to_i` instead of returning the
    HTTP response code, which was very surprising behavior.
  - `Response#body` and `#to_s` will now return a true `String` object rather
    than self. Previously there was no easy way to get the true `String` response
    instead of the Frankenstein response string object with AbstractResponse
    mixed in.
- Handle multiple HTTP response headers with the same name (except for
  Set-Cookie, which is special) by joining the values with a comma space,
  compliant with RFC 7230
- Don't set basic auth header if explicit `Authorization` header is specified
- Add `:proxy` option to requests, which can be used for thread-safe
  per-request proxy configuration, overriding `RestClient.proxy`
- Allow overriding `ENV['http_proxy']` to disable proxies by setting
  `RestClient.proxy` to a falsey value. Previously there was no way in Ruby 2.x
  to turn off a proxy specified in the environment without changing `ENV`.
- Add actual support for streaming request payloads. Previously rest-client
  would call `.to_s` even on RestClient::Payload::Streamed objects. Instead,
  treat any object that responds to `.read` as a streaming payload and pass it
  through to `.body_stream=` on the Net:HTTP object. This massively reduces the
  memory required for large file uploads.
- Remove `RestClient::MaxRedirectsReached` in favor of the normal
  `ExceptionWithResponse` subclasses. This makes the response accessible on the
  exception object as `.response`, making it possible for callers to tell what
  has actually happened when the redirect limit is reached.
- When following HTTP redirection, store a list of each previous response on
  the response object as `.history`. This makes it possible to access the
  original response headers and body before the redirection was followed.
- Add `:before_execution_proc` option to `RestClient::Request`. This makes it
  possible to add procs like `RestClient.add_before_execution_proc` to a single
  request without global state.

# 2.0.0.rc1

Changes in the release candidate that did not persist through the final 2.0.0
release:
- RestClient::Exceptions::Timeout was originally going to be a direct subclass
  of RestClient::Exception in the release candidate. This exception tree was
  made a subclass of RestClient::RequestTimeout prior to the final release.

# 1.8.0

- Security: implement standards compliant cookie handling by adding a
  dependency on http-cookie. This breaks compatibility, but was necessary to
  address a session fixation / cookie disclosure vulnerability.
  (#369 / CVE-2015-1820)

  Previously, any Set-Cookie headers found in an HTTP 30x response would be
  sent to the redirection target, regardless of domain. Responses now expose a
  cookie jar and respect standards compliant domain / path flags in Set-Cookie
  headers.

# 1.7.3

- Security: redact password in URI from logs (#349 / OSVDB-117461)
- Drop monkey patch on MIME::Types (added `type_for_extension` method, use
  the public interface instead.

# 1.7.2

- Ignore duplicate certificates in CA store on Windows

# 1.7.1

- Relax mime-types dependency to continue supporting mime-types 1.x series.
  There seem to be a large number of popular gems that have depended on
  mime-types '~> 1.16' until very recently.

# 1.7.0

- This release drops support for Ruby 1.8.7 and breaks compatibility in a few

- Add support for reading credentials from netrc
- Lots of SSL changes and enhancements: (#268)
  - Enable peer verification by default (setting `VERIFY_PEER` with OpenSSL)
  - By default, use the system default certificate store for SSL verification,
    even on Windows (this uses a separate Windows build that pulls in ffi)
  - Add support for SSL `ca_path`
  - Add support for SSL `cert_store`
  - Add support for SSL `verify_callback` (with some caveats for jruby, OS X, #277)

The response change may be breaking in rare cases.

# 1.3.1

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

# 1.3.0

- 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.

# 1.2.0

- 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

- 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.
