# 2.x release

## v2.0.0-alpha.1

This is a major release. Check [our upgrade guide](https://github.com/bitinn/node-fetch/blob/master/UPGRADE-GUIDE.md) for an overview on some key differences between v1 and v2.

- Major: Node.js 0.10.x support is dropped
- Major: rewrite in transpiled ES2015
- Major: internal methods are no longer exposed
- Major: throw error when a GET/HEAD Request is constructed with a non-null body (per spec)
- Major: `response.text()` no longer attempts to detect encoding, instead always opting for UTF-8 (per spec); use `response.textConverted()` for the old behavior
- Major: make `response.json()` throw error instead of returning an empty object on 204 no-content respose (per spec; reverts behavior set in v1.6.2)
- Major: arrays as parameters to `headers.append` and `headers.set` are joined as a string (per spec)
- Enhance: start testing on Node.js 4, 6, 7
- Enhance: use Rollup to produce a distributed bundle (less memory overhead and faster startup)
- Enhance: make `toString()` on Headers, Requests, and Responses return correct IDL class strings
- Enhance: add an option to conform to latest spec at the expense of reduced compatibility
- Enhance: set `Content-Length` header for Buffers as well
- Enhance: add `response.arrayBuffer()` (also applies to Requests)
- Enhance: add experimental `response.blob()` (also applies to Requests)
- Enhance: make Headers iterable
- Enhance: make Headers constructor accept an array of tuples
- Enhance: make sure header names and values are valid in HTTP
- Fix: coerce Headers prototype function parameters to strings, where applicable
- Fix: fix Request and Response with `null` body
- Fix: support WHATWG URL objects, created by `whatwg-url` package or `require('url').URL` in Node.js 7+
- Other: use Codecov for code coverage tracking

- Fix: support `form-data` 2.x releases (requires `form-data` >= 2.1.0)

## v1.6.2

- Enhance: minor document update
- Fix: response.json() returns empty object on 204 no-content response instead of throwing a syntax error

## v1.6.1

- Fix: if `res.body` is a non-stream non-formdata object, we will call `body.toString` and send it as a string
- Fix: `counter` value is incorrectly set to `follow` value when wrapping Request instance
- Fix: documentation update

## v1.6.0

- Enhance: added `res.buffer()` api for convenience, it returns body as a Node.js buffer
- Enhance: better old server support by handling raw deflate response
- Enhance: skip encoding detection for non-HTML/XML response
- Enhance: minor document update
- Fix: HEAD request doesn't need decompression, as body is empty
- Fix: `req.body` now accepts a Node.js buffer

## v1.5.3

- Fix: handle 204 and 304 responses when body is empty but content-encoding is gzip/deflate
- Fix: allow resolving response and cloned response in any order
- Fix: avoid setting `content-length` when `form-data` body use streams
- Fix: send DELETE request with content-length when body is present
- Fix: allow any url when calling new Request, but still reject non-http(s) url in fetch

## v1.5.2

## v1.5.0

- Enhance: `FetchError` contains `err.type` and `err.code`, allows for better error handling (thx to @pekeler)

## v1.4.1

- Fix: wrapping Request instance with FormData body again should preserve the body as-is

## v1.4.0

- Enhance: Request and Response now have `clone` method (thx to @kirill-konshin for the initial PR)
- Enhance: Request and Response now have proper string and buffer body support (thx to @kirill-konshin)
- Enhance: Body constructor has been refactored out (thx to @kirill-konshin)
- Enhance: Headers now has `forEach` method (thx to @tricoder42)
- Enhance: back to 100% code coverage
- Fix: better form-data support (thx to @item4)
- Fix: better character encoding detection under chunked encoding (thx to @dsuket for the initial PR)

## v1.3.3

- Fix: make sure `Content-Length` header is set when body is string for POST/PUT/PATCH requests
