File: CHANGELOG — Documentation for savon_with

2.4.0 (2014-03-31)

Logging is off by default. To enable this behavior, set the :log option to true

client = Savon.client(wsdl: "http://example.com/service.wsdl")
client.options[:log] = true

2.3.2 (2013-12-09)

Fix: #520 Fixes a regression in message tags in requests and responses.

2.3.1 (2013-12-05)

Removed dependency on Nokogiri <= 1.4 -- This improves support for ruby 1.9.3 and 2.0.0 and officially begins the end of support for ruby 1.8.7 See issue #487

2.3.0 (2013-07-27)

Combined release ticket: #481

Feature: #405 Improved NTLM support based on HTTPI v2.1.0.
Feature: #424 Adds support for multipart responses through the updated savon-multipart gem. You can now specify multipart: true either as a global or local option. Please make sure you have the updated savon-multipart gem installed and loaded, as it is not a direct dependency of Savon.
```
require 'savon'
require 'savon-multipart'

# expect multipart responses for every operation
client = Savon.client(wsdl: wsdl, multipart: true)

# only expect a multipart response for this operation
client.call(:my_operation, multipart: true)
```
Feature: #470 Added a local :soap_header option to allow setting the SOAP header per request.
Feature: #402 Makes it possible to create mocks that don't care about the message sent by using :any for the :message option.
```
savon.expects(:authenticate).with(message: :any)
```
Fix: #450 Added Savon::Response#soap_fault and Savon::Response#http_error which were present in version 1.
Fix: #474 Changed Savon::Response#header and Savon::Response#body to respect the global :convert_response_tags_to and :strip_namespaces options and return the expected result instead of raising a Savon::InvalidResponseError.
Fix: #461 Fixed two problems related to namespace qualified messages and the element :order!.
Fix: #476 fixes a problem where the namespace for the message tag was not correctly determined from the WSDL.
Fix: #468 Changed the dependency on Nokogiri to < 1.6, because Nokogiri 1.6 dropped support for Ruby 1.8.

2.2.0 (2013-04-21)

Feature: #416 The global namespace_identifier option can now be set to nil to not add a namespace identifier to the message tag.
Feature: #408 Added Savon::Client#service_name to return the name of the SOAP service.
Improvement: When mistyping an option name, Savon used to raise a simple NoMethodError. This is because regardless of whether you're using the Hash or block syntax to pass global or local options, both are just method calls on some options object.
```
NoMethodError: undefined method 'wsdk' for #<Savon::GlobalOptions:0x007fed95a55228>
```

As of this change, Savon now catches those errors and raise a Savon::UnknownOptionError with a slightly more helpful error message instead.

``` ruby
Savon::UnknownOptionError:
   Unknown global option: :wsdk
```

Improvement: #385 Instead of raising an ArgumentError when Wasabi can't find any operations in the WSDL. Savon now raises a Savon::UnknownOperationError. This might happen when Wasabi fails to parse the WSDL because of imports for example.
Fix: #430 allows you to rescue and ignore Savon::Error errors in production while still having mocks trigger test failures.
Fix: #393 changed Savon::SOAPFault to work with generic response Hash keys.
Fix: #423 fixes a problem where Wasabi was not able to find extension base elements defined in imports it didn't follow.

2.1.0 (2013-02-03)

Feature: #372 added global ssl_cert_key_password option.
Feature: #361 added the local :attributes option to allow adding XML attributes to the SOAP message tag.
Improvement: #363 Savon 2.0 remembers the cookies from the last response and passes it to the next request, which is not a proper way to handle cookies. I removed this behavior and introduced an easy way to handle cookies manually instead.
Improvement: #380 changed the gemspec to not rely on git.
Fix: #378 use the proxy option for WSDL requests.
Fix: #369 use HTTP basic and digest authentication credentials to retrieve WSDL files. Fixes #367.
Fix: #349 global timeout and SSL options are now used to retrieve a remote WSDL document.
Fix: #353 simplified logging. the global :log option is now only used to store whether Savon should log instead of creating a new Logger and changing its logdev to $stdout or /dev/null depending on the what was passed.

This also fixes rubiii/savon#2 and #379.

Fix: #376 added a global namespaces option for adding namespaces to the SOAP envelope.

2.0.3 (2013-01-19)

Upgraded Nori dependency to prevent people from using a version that is vulnerable to the recent remote code execution bug.

2.0.2 (2012-12-20)

Fix: #297 added the global :ssl_verify_mode and :ssl_version options which were missing.
Fix: #344 added missing global ssl cert options :ssl_cert_file, :ssl_cert_key_file and :ssl_ca_cert_file.

2.0.1 (2012-12-19)

Fix #342 fixes an issue where namespaces could not be resolved if the actual operation name to call did not match the operation name passed to the client's #call method. For example: :get_stations for a getStations operation.

2.0.0 (2012-12-18)

Read about all the changes in the updated documentation.
Fix: #322 use the builder's state instead of the block's return value to set the soap body/xml values.
Fix: #327 response.to_array now properly returns FalseClass values.
Fix: 320 use the correct SOAP namespace when the SOAP version changes between requests.
Fix: 321 preserve [false] values in Hashes.

1.2.0 (2012-09-15)

Fix: #312 recursively determines the proper namespaces for SOAP body Hashes with nested Arrays of Hashes.
Improvement: #318 isolates building the request to improve threadsafety.
Refactoring: Use the Wasabi::Document with resolver instead of the custom Savon::Wasabi::Document.

1.1.0 (2012-06-28)

Improvement: Changed Savon's core dependencies to be more strict and only allow bug fix changes. Major or minor releases of these dependencies now need a release of Savon so they can be used. This should improve the stability of the library and make it easier to update, because changes to these core dependencies will be documented here as well.
Fix: The latest version of Wasabi should now correctly detect the names of your operations. So you should be able to just get the names of some operation:
```
client.wsdl.soap_actions
# => [:authenticate, :find_user]
```
and pass the Symbol to execute a request:
```
client.request :authenticate, body: { token: "secret" }
```
If you still pass anything other than a single Symbol to that method, please open an issue! You shouldn't need to specify a namespace or additional attributes for the tag.
Refactoring: Moved code that sets the cookies from the last response for the next request to HTTPI::Request#set_cookies.

1.0.0 (2012-06-09)

Fix: Savon.client didn't pass the optional block.
Improvement: #291 changed the :soap_request hook to act like an around filter. The hook now receives a callback block to execute the SOAP call and can return the result of the callback to continue the request. It can also not call the callback block and return some HTTPI::Response to mock the SOAP request.

As this change affects savon_spec, you need to update savon_spec to v1.3.0.

0.9.14 (2012-06-07)

Fix: #292 again

0.9.13 (2012-06-07)

Fix: #292

0.9.12 (2012-06-07)

Re-added the log method setters to the new config object for backwards compatibility. You should be able to configure the logger as you used to do.

Savon.configure do |config|
  config.log = false            # disable logging
  config.log_level = :info      # changing the log level
  config.logger = Rails.logger  # using the Rails logger
end

0.9.11 (2012-06-06)

Feature: #264 - Thanks to @hoverlover, Savon and Akami now support signed messages through WSSE.
Fix: #275 - Add namespaces to keys in both the SOAP body hash as well as any keys specified in a :order! Array instead of having to define them manually.
Fix: #257 - Add ability to accept and send multiple cookies.

Improvement: #277 automatically namespace the SOAP input tag. Here's an example from the pull request:

client.request :authenticate

Note the automatic namespace identifier on the authenticate element, as well as the proper namespace inclusion in the document:

<env:Envelope
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:tns="http://v1_0.ws.auth.order.example.com/"
    xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">

    <tns:authenticate>
        <tns:user>username</tns:user>
        <tns:password>password</tns:password>
    </tns:authenticate>
</env:Envelope>

0.9.10 (2012-06-06)

Feature: #289 - Allow the SOAP envelope header to be set as a String.
Feature: In addition to the global configuration, there's now also one configuration per client. The global config is cloned when a new client is initialized and gets used instead of the global one. In addition, for Savon::Model classes, the config is cloned per class.

Closes #84 by allowing one logger per client and #270 by allowing to specify error handling per client.

Feature: Added an option to pretty print XML in log messages. Closes #256 and #280.

# global
Savon.configure do |config|
  config.pretty_print_xml = true
end

# per client
client.config.pretty_print_xml = true

Refactoring:
- Added Savon.client as a shortcut for creating a new Savon::Client
- Changed Savon::Config from a module to a class.
- Moved logging to the new Savon::Logger object.
- Removed the blank? extension from Object.

0.9.9 (2012-02-17)

Improvement: pull request 255 - Raise an error if fetching a remote WSDL fails. Possible fix for issue 236.
Improvement: The value for elementFormDefault (:unqualified, :qualified) can now be specified when creating a Savon::Client. For example:
```
Savon::Client.new do
  wsdl.element_form_default = :unqualified
end
```
Improvement: pull request 263 - The SOAP action can now be set via a :soap_action key passed to the #request method.
```
client.request(:get_user, :soap_action => :test_action)
```
Fix: pull request 265 - Fixes gemspec problems when bundling under JRuby 1.6.5. Also fixes issue 267.

0.9.8 (2012-02-15)

Feature: Savon now ships with Savon::Model. Savon::Model is a lightweight DSL to be used inside your domain models. It's been refactored and is now even more useful than before.
Feature: Merged pull request 230 to allow filtering values in logged SOAP request XML messages.
```
Savon.configure do |config|
  config.log_filter = ["password"]
end
```
Feature: Added an option to change the default encoding of the XML directive tag (defaults to UTF-8) to fix issue 234.
```
client.request(:find_user) do
  soap.encoding = "UTF-16"
  soap.body = { :id => 1 }
end
```
Improvement: Merged pull request 231 to gracefully handle invalid response bodies by throwing a Savon::SOAP::InvalidResponseError.
Fix: issue 237 - Set the Content-Type and Content-Length headers for every request.
Fix: pull request 250 - The Content-Length header should be the size in bytes.

0.9.7 (2011-08-25)

Feature: Merged pull request 210 by mboeh to add Savon::SOAP::Response#doc and Savon::SOAP::Response#xpath.
Feature: Merged pull request 211 by mattkirman to fix issue 202.

Feature: You can now pass a block to Savon::SOAP::XML#body and use Builder to create the XML:

client.request(:find) do
  soap.body do |xml|
    xml.user do
      xml.id 601173
    end
  end
end

Fix: issue 218 - Savon now correctly handles namespaced Array items in a Hash passed to Savon::SOAP::XML#body=.
Fix: Merged pull request 212 to fix savon_spec issue 2.
Improvement: issue 222 - Set the Content-Length header.

0.9.6 (2011-07-07)

Improvement/Fix: Updated Savon to use the latest version of Wasabi. This should fix issue 155 - Savon can automatically add namespaces to SOAP requests based on the WSDL. Users shouldn't need to do anything differently or even notice whether their WSDL hits this case; the intention is that this will "Just Work" and follow the WSDL. The SOAP details are that if elementFormDefault is specified as qualified, Savon will automatically prepend the correct XML namespaces to the elements in a SOAP request. Thanks to jkingdon for this.
Fix: issue 143 - Updating Wasabi should solve this issue.

0.9.5 (2011-07-03)

Refactoring: Extracted WSSE authentication out into the akami gem.

0.9.4 (2011-07-03)

Refactoring: Extracted the WSDL parser out into the wasabi gem. This should isolate upcoming improvements to the parser.

0.9.3 (2011-06-30)

Fix: issue 138 - Savon now supports setting a global SOAP header via Savon.soap_header=.
Fixed the namespace for wsse message timestamps from wsse:Timestamp to wsu:Timestamp as required by the specification.
Change: Removed support for NTLM authentication until it's stable. If you need it, you can still add the following line to your Gemfile:
```
gem "httpi", "0.9.4"
```
Refactoring:
- Hash#map_soap_response and some of its helpers are moved to Nori v1.0.0. Along with replacing core extensions with a proper implementation, Nori now contains a number of methods for configuring its default behavior:
  - The option whether to strip namespaces was moved to Nori.strip_namespaces
  - You can disable "advanced typecasting" for SOAP response values
  - And you can configure how SOAP response keys should be converted
- Savon::SOAP::XML.to_hash, Savon::SOAP::XML.parse and Savon::SOAP::XML.to_array are gone. It wasn't worth keeping them around, because they didn't do much. You can simply parse a SOAP response and translate it to a Savon SOAP response Hash via:
```
Nori.parse(xml)[:envelope][:body]
```
- Savon::SOAP::Response#basic_hash is now Savon::SOAP::Response#hash.

0.9.2 (2011-04-30)

Fix: issue 154 - Timezone format used by Savon now matches the XML schema spec.
Improvement: WSSE basic, digest and timestamp authentication are no longer mutually exclusive. Thanks to mleon for solving issue #142.
Improvement: Switched from using Crack to translate the SOAP response to a Hash to using Nori. It's based on Crack and comes with pluggable parsers. It defaults to REXML, but you can switch to Nokogiri via:
```
Nori.parser = :nokogiri
```
Improvement: WSDL parsing now uses Nokogiri instead of REXML.

0.9.1 (2011-04-06)

Improvement: if you're only setting the local or remote address of your wsdl document, you can now pass an (optional) String to Savon::Client.new to set wsdl.document.
```
Savon::Client.new "http://example.com/UserService?wsdl"
```
Improvement: instead of calling the to_hash method of your response again and again and again, there is now a #[] shortcut for you.
```
response[:authenticate_response][:return]
```

0.9.0 (2011-04-05)

Feature: issues #158, #169 and #172 configurable "Hash key Symbol to lowerCamelCase" conversion by using the latest version of Gyoku.

Gyoku.convert_symbols_to(:camelcase)
Gyoku.xml(:first_name => "Mac")  # => "<FirstName></Firstname>"

You can even define your own conversion formular.

Gyoku.convert_symbols_to { |key| key.upcase }
Gyoku.xml(:first_name => "Mac")  # => "<FIRST_NAME></FIRST_NAME>"

This should also work for the SOAP input tag and SOAPAction header. So if you had to use a String for the SOAP action to call because your services uses CamelCase instead of lowerCamelCase, you can now change the default and use Symbols instead.

Gyoku.convert_symbols_to(:camelcase)

# pre Gyoku 0.4.0
client.request(:get_user)  # => "<getUser/>
client.request("GetUser")  # => "<GetUser/>"

# post Gyoku 0.4.0
client.request(:get_user)  # => "<GetUser/>"

Improvement: issues #170 and #173 Savon no longer rescues exceptions raised by Crack::XML.parse. If Crack complains about your WSDL document, you should take control and solve the problem instead of getting no response.

Improvement: issue #172 support for global env_namespace.

Savon.configure do |config|
  config.env_namespace = :soapenv  # changes the default :env namespace
end

Fix: issue #163 "Savon 0.8.6 not playing nicely with Httpi 0.9.0". Updating HTTPI to v0.9.1 should solve this problem.
And if you haven't already seen the new documentation: savonrb.com

0.8.6 (2011-02-15)

Fix for issues issue #147 and #151 (771194).

0.8.5 (2011-01-28)

Fix for issue #146 (98655c).
Fix for issue #147 (252670).

0.8.4 (2011-01-26)

Fix for issues issue #130 and #134 (4f9847).
Fix for issue #91 (5c8ec1).
Fix for issue #135 (c9261d).

0.8.3 (2011-01-11)

Moved implementation of Savon::SOAP::Response#to_array to a class method at Savon::SOAP::XML.to_array (05a7d3).
Fix for issue #131 (4e57b3).

0.8.2 (2011-01-04)

Fix for issue #127 (0eb3da).

Changed Savon::WSSE to be based on a Hash instead of relying on builder (4cebc3).

Savon::WSSE now supports wsse:Timestamp headers (issue #122) by setting Savon::WSSE#timestamp to true:

client.request :some_method do
  wsse.timestamp = true
end

or by setting Savon::WSSE#created_at or Savon::WSSE#expires_at:

client.request :some_method do
  wsse.created_at = Time.now
  wsse.expires_at = Time.now + 60
end

You can also add custom tags to the WSSE header (issue #69):

client.request :some_method do
  wsse["wsse:Security"]["wsse:UsernameToken"] = { "Organization" => "ACME", "Domain" => "acme.com" }
end

0.8.1 (2010-12-22)

Update to depend on HTTPI v0.7.5 which comes with a fallback to use Net::HTTP when no other adapter could be required.
Fix for issue #72 (22074a).
Loosen dependency on builder. Should be quite stable.

0.8.0 (2010-12-20)

Added Savon::SOAP::XML#env_namespace (51fa0e) to configure the SOAP envelope namespace. It defaults to :env but can also be set to an empty String for SOAP envelope tags without a namespace.
Replaced quite a lot of core extensions by moving the Hash to XML translation into a new gem called Gyoku (bac4b4).

0.8.0.beta.4 (2010-11-20)

Fix for issue #107 (1d6eda).
Fix for issue #108 (f64400...0aaca2) Thanks fagiani.
Replaced Savon.response_pattern with a slightly different implementation of the Savon::SOAP::Response#to_array method (6df6a6). The method now accepts multiple arguments representing the response Hash keys to traverse and returns the result as an Array or an empty Array in case the key is nil or does not exist.
```
response.to_array :get_user_response, :return
# => [{ :id => 1, :name => "foo"}, { :id => 2, :name => "bar"}]
```

0.8.0.beta.3 (2010-11-06)

Fix for savon_spec to not send nil to Savon::SOAP::XML#body (c34b42).

0.8.0.beta.2 (2010-11-05)

Added Savon.response_pattern (0a12fb) to automatically walk deeper into the SOAP response Hash when a pattern (specified as an Array of Regexps and Symbols) matches the response. If for example your response always looks like ".+Response/return" as in:
```
  <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
      <ns2:authenticateResponse xmlns:ns2="http://v1_0.ws.user.example.com">
        <return>
          <some>thing</some>
        </return>
      </ns2:authenticateResponse>
    </soap:Body>
  </soap:Envelope>
```
you could set the response pattern to:
```
Savon.configure do |config|
  config.response_pattern = [/.+_response/, :return]
end
```
then instead of calling:
```
response.to_hash[:authenticate_response][:return]  # :some => "thing"
```
to get the actual content, Savon::SOAP::Response#to_hash will try to apply given the pattern:
```
response.to_hash  # :some => "thing"
```
Please notice, that if you don't specify a response pattern or if the pattern doesn't match the response, Savon will behave like it always did.
Added Savon::SOAP::Response#to_array (which also uses the response pattern).

0.8.0.beta.1 (2010-10-29)

Changed Savon::Client.new to accept a block instead of multiple Hash arguments. You can access the wsdl, http and wsse objects inside the block to configure your client for a particular service.

# Instantiating a client to work with a WSDL document
client = Savon::Client.new do
  wsdl.document = "http://example.com?wsdl"
end

# Directly accessing the SOAP endpoint
client = Savon::Client.new do
  wsdl.endpoint = "http://example.com"
  wsdl.namespace = "http://v1.example.com"
end

Fix for issue #77, which means you can now use local WSDL documents:

client = Savon::Client.new do
  wsdl.document = "../wsdl/service.xml"
end

Changed the way SOAP requests are being dispatched. Instead of using method_missing, you now use the new request method, which also accepts a block for you to access the wsdl, http, wsse and soap object. Please notice, that a new soap object is created for every request. So you can only access it inside this block.
```
# A simple request to an :authenticate method
client.request :authenticate do
  soap.body = { :id => 1 }
end
```

The new Savon::Client#request method fixes issues #37, #61 and #64, which report problems with namespacing the SOAP input tag and attaching attributes to it. Some usage examples:

client.request :get_user                  # Input tag: <getUser>
client.request :wsdl, "GetUser"           # Input tag: <wsdl:GetUser>
client.request :get_user :active => true  # Input tag: <getUser active="true">

Savon's new request method respects the given namespace. If you don't give it a namespace, Savon will set the target namespace to "xmlns:wsdl". But if you do specify a namespace, it will be set to the given Symbol.
Refactored Savon to use the new HTTPI gem. HTTPI::Request replaces the Savon::Request, so please make sure to have a look at the HTTPI library and let me know about any problems. Using HTTPI actually fixes the following two issues.
Savon now adds both "xmlns:xsd" and "xmlns:xsi" namespaces for you. Thanks Averell. It also properly serializes nil values as xsi:nil = "true".
Fix for issue #24. Instead of Net/HTTP, Savon now uses HTTPI to execute HTTP requests. HTTPI defaults to use HTTPClient which supports HTTP digest authentication.
Fix for issue #76. You now have to explicitly specify whether to use a WSDL document, when instantiating a client.
Fix for issue #75. Both Savon::SOAP::Fault and Savon::HTTP::Error now contain the HTTPI::Response. They also inherit from Savon::Error, making it easier to rescue both at the same time.
Fix for issue #87. Thanks to Leonardo Borges.
Fix for issue #81. Replaced Savon::WSDL::Document#to_s with a to_xml method.
Fix for issues #85 and #88.
Fix for issue #80.
Fix for issue #60.
Fix for issue #96.
Removed global WSSE credentials. Authentication needs to be set up for each client instance.
Started to remove quite a few core extensions.

0.7.9 (2010-06-14)

Fix for issue #53.

0.7.8 (2010-05-09)

Fixed gemspec to include missing files in the gem.

0.7.7 (2010-05-09)

SOAP requests now start with a proper XML declaration.
Added support for gzipped requests and responses (http://github.com/lucascs). While gzipped SOAP responses are decoded automatically, you have to manually instruct Savon to gzip SOAP requests:
```
client = Savon::Client.new "http://example.com/UserService?wsdl", :gzip => true
```
Fix for issue #51. Added the :soap_endpoint option to Savon::Client.new which lets you specify a SOAP endpoint per client instance:
```
client = Savon::Client.new "http://example.com/UserService?wsdl",
  :soap_endpoint => "http://localhost/UserService"
```
Fix for issue #50. Savon still escapes special characters in SOAP request Hash values, but you can now append an exclamation mark to Hash keys specifying that it's value should not be escaped.

0.7.6 (2010-03-21)

Moved documentation from the Github Wiki to the actual class files and established a much nicer documentation combining examples and implementation (using Hanna) at: http://savon.rubiii.com
Added Savon::Client#call as a workaround for dispatching calls to SOAP actions named after existing methods. Fix for issue #48.
Add support for specifying attributes for duplicate tags (via Hash values as Arrays). Fix for issue #45.
Fix for issue #41.
Fix for issues #39 and #49. Added Savon::SOAP#xml which let's you specify completely custom SOAP request XML.

0.7.5 (2010-02-19)

Fix for issue #34.
Fix for issue #36.
Added feature requested in issue #35.
Changed the key for specifying the order of tags from :@inorder to :order!

0.7.4 (2010-02-02)

Fix for issue #33.

0.7.3 (2010-01-31)

Added support for Geotrust-style WSDL documents (Julian Kornberger [email protected]).
Make HTTP requests include path and query only. This was breaking requests via proxy as scheme and host were repeated (Adrian Mugnolo [email protected])
Avoid warning on 1.8.7 and 1.9.1 (Adrian Mugnolo [email protected]).
Fix for issue #29. Default to UTC to xs:dateTime value for WSSE authentication.
Fix for issue #28.
Fix for issue #27. The Content-Type now defaults to UTF-8.
Modification to allow assignment of an Array with an input name and an optional Hash of values to soap.input. Patches issue #30 (stanleydrew [email protected]).
Fix for issue #25.

0.7.2 (2010-01-17)

Exposed the Net::HTTP response (added by Kevin Ingolfsland). Use the http accessor (response.http) on your Savon::Response to access the Net::HTTP response object.
Fix for issue #21.
Fix for issue #22.
Fix for issue #19.
Added support for global header and namespaces. See issue #9.

0.7.1 (2010-01-10)

The Hash of HTTP headers for SOAP calls is now public via Savon::Request#headers. Patch for issue #8.

0.7.0 (2010-01-09)

This version comes with several changes to the public API! Pay attention to the following list and read the updated Wiki: http://wiki.github.com/savonrb/savon

Changed how Savon::WSDL can be disabled. Instead of disabling the WSDL globally/per request via two different methods, you now simply append an exclamation mark (!) to your SOAP call: client.get_all_users! Make sure you know what you're doing because when the WSDL is disabled, Savon does not know about which SOAP actions are valid and just dispatches everything.
The Net::HTTP object used by Savon::Request to retrieve WSDL documents and execute SOAP calls is now public. While this makes the library even more flexible, it also comes with two major changes:
- SSL client authentication needs to be defined directly on the Net::HTTP object:
```
  client.request.http.client_cert = ...
```
I added a shortcut method for setting all options through a Hash similar to the previous implementation:
```
  client.request.http.ssl_client_auth :client_cert => ...
```
- Open and read timeouts also need to be set on the Net::HTTP object:
```
  client.request.http.open_timeout = 30
  client.request.http.read_timeout = 30
```
- Please refer to the Net::HTTP documentation for more details: http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/index.html
Thanks to JulianMorrison, Savon now supports HTTP basic authentication:
```
client.request.http.basic_auth "username", "password"
```
Julian also added a way to explicitly specify the order of Hash keys and values, so you should now be able to work with services requiring a specific order of input parameters while still using Hash input.
```
client.find_user { |soap| soap.body = { :name => "Lucy", :id => 666, :@inorder => [:id, :name] } }
```
Savon::Response#to_hash now returns the content inside of "soap:Body" instead of trying to go one level deeper and return it's content. The previous implementation only worked when the "soap:Body" element contained a single child. See issue #17.
Added Savon::SOAP#namespace as a shortcut for setting the "xmlns:wsdl" namespace.
```
soap.namespace = "http://example.com"
```

0.6.8 (2010-01-01)

Improved specifications for various kinds of WSDL documents.
Added support for SOAP endpoints which are different than the WSDL endpoint of a service.
Changed how SOAP actions and inputs are retrieved from the WSDL documents. This might break a few existing implementations, but makes Savon work well with even more services. If this change breaks your implementation, please take a look at the action and input methods of the Savon::SOAP object. One specific problem I know of is working with the createsend WSDL and its namespaced actions.

To make it work, call the SOAP action without namespace and specify the input manually:
```
  client.get_api_key { |soap| soap.input = "User.GetApiKey" }
```

0.6.7 (2009-12-18)

Implemented support for a proxy server. The proxy URI can be set through an optional Hash of options passed to instantiating Savon::Client (Dave Woodward [email protected])
Implemented support for SSL client authentication. Settings can be set through an optional Hash of arguments passed to instantiating Savon::Client (colonhyphenp)
Patch for issue #10.

0.6.6 (2009-12-14)

Default to use the name of the SOAP action (the method called in a client) in lowerCamelCase for SOAP action and input when Savon::WSDL is disabled. You still need to specify soap.action and maybe soap.input in case your SOAP actions are named any different.

0.6.5 (2009-12-13)

Added an open_timeout method to Savon::Request.

0.6.4 (2009-12-13)

Refactored specs to be less unit-like.
Added a getter for the Savon::Request to Savon::Client and a read_timeout setter for HTTP requests.
wsdl.soap_actions now returns an Array of SOAP actions. For the previous "mapping" please use wsdl.operations.

Replaced WSDL document with stream parsing.

method_missing now yields the SOAP and WSSE objects to a given block.
The response_process (which previously was a block passed to method_missing) was replaced by Savon::Response.
Improved SOAP action handling (another problem that came up with issue #1).
