Breaking changes

Breaking changes are in rarely used functionality, so we hope upgrade will be smooth for most users.

• Browser: The .parse() method has been renamed to .serialize() to avoid inconsistency with NodeJS version (v1.8.3 supports .serialize() too)
• Browser: Query string keys without a value used to be parsed as 'undefined', now their value is '' (empty string) (shura, Kornel Lesiński).
• NodeJS: The redirect event is called after new query string and headers have been set and is allowed to override the request URL (Kornel Lesiński)
• .then() returns a real Promise. Note that use of superagent with promises now requires a global Promise object.
  If you target Internet Explorer or Node 0.10, you'll need require('es6-promise').polyfill() or similar.
• Upgraded all dependencies (Peter Lyons)
• Renamed properties documented as @api private to have _prefixed names (Kornel Lesiński)

Probably not breaking changes:

• Extracted common functions to request-base (Peter Lyons)
• Fixed race condition in pipe tests (Peter Lyons)
• Handle FormData error events (scriptype)
• Fixed wrong jsdoc of Request#attach (George Chung)
• Updated and improved tests (Peter Lyons)

v1.8.2

• Fixed handling of HTTP status 204 with content-encoding: gzip (Andrew Shelton)
• Handling of FormData error events (scriptype)
• Fixed parsing of vnd+json MIME types (Kornel Lesiński)
• Aliased browser implementation of .parse() as .serialize() for forward compatibility

v1.8.0

• Extracted common code into request-base class (Peter Lyons)
  • It does not affect the public API, but please let us know if you notice any plugins/subclasses breaking!
• Added option {type:'auto'} to auth method, which enables browser-native auth types (Jungle, Askar Yusupov)
• Added responseType() to set XHR responseType (chris)
• Switched to form-data for browserify-compatible FormData (Peter Lyons)
• Added statusCode to error response when JSON response is malformed (mattdell)
• Prevented TCP port conflicts in all tests (Peter Lyons)
• Updated form-data dependency

v1.7.2
