 Change History
 ==============
+* 0.9.0 - Compatibility fixes to bring node-oauth up to speed with node.js 0.4x [thanks to Rasmus Andersson for starting the work ]
 * 0.8.4 - Fixed issue #14 (Parameter ordering ignored encodings).  Added support for repeated parameter names. Implements issue #15 (Use native SHA1 if available, 10x speed improvement!). Fixed issue #16 (Should use POST when requesting access tokens.).  Fixed Issue #17 (OAuth2 spec compliance).  Implemented enhancement #13 (Adds support for PUT & DELETE http verbs). Fixes issue #18 (Complex/Composite url arguments [thanks novemberborn])
 * 0.8.3 - Fixed an issue where the auth header code depended on the Array's toString method (Yohei Sasaki) Updated the getOAuthRequestToken method so we can access google's OAuth secured methods. Also re-implemented and fleshed out the test suite.
 * 0.8.2 - The request returning methods will now write the POST body if provided (Chris Anderson), the code responsible for manipulating the headers is a bit safe now when working with other code (Paul McKellar) and tweaked the package.json to use index.js instead of main.js
