If you want to guarantee a stable streams base, regardless of what version of
Node you, or the users of your libraries are using, use **readable-stream***only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
As of version 2.0.0 **readable-stream** uses semantic versioning.
## Version 3.x.x
v3.x.x of `readable-stream` is a cut from Node 10. This version supports Node 6, 8, and 10, as well as evergreen browsers, IE 11 and latest Safari. The breaking changes introduced by v3 are composed by the combined breaking changes in [Node v9](https://nodejs.org/en/blog/release/v9.0.0/) and [Node v10](https://nodejs.org/en/blog/release/v10.0.0/), as follows:
v2.x.x of `readable-stream` is a cut of the stream module from Node 8 (there have been no semver-major changes from Node 4 to 8). This version supports all Node.js versions from 0.8, as well as evergreen browsers and IE 10 & 11.

# Usage
You can swap your `require('stream')` with `require('readable-stream')`
without any changes, if you are just using one of the main classes and
functions.
```js
const {
Readable,
Writable,
Transform,
Duplex,
pipeline,
finished
} = require('readable-stream')
````
Note that `require('stream')` will return `Stream`, while
`require('readable-stream')` will return `Readable`. We discourage using
whatever is exported directly, but rather use one of the properties as
shown in the example above.
# Streams Working Group
`readable-stream` is maintained by the Streams Working Group, which
oversees the development and maintenance of the Streams API within
Node.js. The responsibilities of the Streams Working Group include:
* Addressing stream issues on the Node.js issue tracker.
* Authoring and editing stream documentation within the Node.js project.
* Reviewing changes to stream subclasses within the Node.js project.
* Redirecting changes to streams from the Node.js project to this
project.
* Assisting in the implementation of stream providers within Node.js.
* Recommending versions of `readable-stream` to be included in Node.js.
* Messaging about the future of streams to give the community advance
