4.0.0 (2018-11-17)

Breaking changes

• Node.js v4 has reached it's end of life, so we no longer support it. It's v6+ or later. We recommend Node.js 10.
• We now use ES6 in the browser code, too.
  • If you're using Browserify or Webpack to package code for Internet Explorer, you will also have to use Babel.
  • The pre-built node_modules/superagent.js is still ES5-compatible.
• .end(…) returns undefined instead of the request. If you need the request object after calling .end() (and you probably don't), save it in a variable and call request.end(…). Consider not using .end() at all, and migrating to promises by calling .then() instead.
• In Node, responses with unknown MIME type are buffered by default. To get old behavior, if you use custom unbuffered parsers, add .buffer(false) to requests or set superagent.buffer[yourMimeType] = false.
• Invalid uses of .pipe() throw.

Minor changes

• Throw if req.abort().end() is called
• Throw if using unsupported mix of send and field
• Reject .end() promise on all error events (Kornel Lesiński)
• Set https.servername from the Host header (Kornel Lesiński)
• Leave backticks unencoded in query strings where possible (Ethan Resnick)
• Update node-mime to 2.x (Alexey Kucherenko)
• Allow default buffer settings based on response-type (shrey)
• response.buffered is more accurate.
