 # 1.x release
 
-## v1.5.3 (master)
+## v1.6.0 (master)
+
+- 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: handles 204 and 304 responses when body is empty but content-encoding is gzip/deflate
 - Fix: allow resolving response and cloned response in any order

 - For convenience, `res.body` is a transform stream, so decoding can be handled independently.

 # Motivation
 
-I really like the notion of Matt Andrews' [isomorphic-fetch](https://github.com/matthew-andrews/isomorphic-fetch): it bridges the API gap between client-side and server-side http requests, so developers have less to worry about.
+Instead of implementing `XMLHttpRequest` in Node.js to run browser-specific [Fetch polyfill](https://github.com/github/fetch), why not go from native `http` to `Fetch` API directly? Hence `node-fetch`, minimal code for a `window.fetch` compatible API on Node.js runtime.
 
-Instead of implementing `XMLHttpRequest` in node to run browser-specific [fetch polyfill](https://github.com/github/fetch), why not go from node's `http` to `fetch` API directly? Node has native stream support, browserify build targets (browsers) don't, so underneath they are going to be vastly different anyway.

 - Make conscious trade-off when following [whatwg fetch spec](https://fetch.spec.whatwg.org/) and [stream spec](https://streams.spec.whatwg.org/) implementation details, document known difference.
 - Use native promise, but allow substituting it with [insert your favorite promise library].
 - Use native stream for body, on both request and response.
-- Decode content encoding (gzip/deflate) properly, and convert string output (such as `res.text()` and `res.json()`) to utf-8 automatically.
-- Useful extensions such as timeout, redirect limit, response size limit, explicit reject errors.
