We no longer support Node 0.x. If you're still using Internet Explorer 6 Node 0.x, please please upgrade ASAP, as the old Node isn't even getting security patches any more.

• Multiple .send() calls mixing Buffer/Blob and JSON data are not possible and will now throw instead of messing up the data.

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)
