Notable changes:

Diagnostics channel (experimental module):

`diagnostics_channel` is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes.

The module was initially introduced in Node.js v15.1.0 and is backported to v14.17.0
to enable testing it at a larger scale.

With `diagnostics_channel`, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example. Just create a named channel with `dc.channel(name)` and call `channel.publish(data)` to send the data to any listeners to that channel.

```js
const dc = require('diagnostics_channel');
const channel = dc.channel('mysql.query');

MySQL.prototype.query = function query(queryString, values, callback) {
  // Broadcast query information whenever a query is made
  channel.publish({
    query: queryString,
    host: this.hostname,
  });

  this.doQuery(queryString, values, callback);
};
```

Channels are like one big global event emitter but are split into separate objects to ensure they get the best performance. If nothing is listening to the channel, the publishing overhead should be as close to zero as possible. Consuming channel data is as easy as using `channel.subscribe(listener)` to run a function whenever a message is published to that channel.

```js
const dc = require('diagnostics_channel');
const channel = dc.channel('mysql.query');

channel.subscribe(({ query, host }) => {
  console.log(`mysql query to ${host}: ${query}`);
});
```

The data captured can be used to provide context for what an app is doing at a given time. This can be used for things like augmenting tracing data, tracking network and filesystem activity, logging queries, and many other things. It's also a very useful data source for diagnostics tools to provide a clearer picture of exactly what the application is doing at a given point in the data they are presenting.

UUID support in the crypto module:

The new `crypto.randomUUID()` method now allows to generate random
[RFC 4122](https://www.rfc-editor.org/rfc/rfc4122.txt) Version 4 UUID strings:

```js
const { randomUUID } = require('crypto');

console.log(randomUUID());
// 'aa7c91a1-f8fc-4339-b9db-f93fc7233429'
```

Experimental support for `AbortController` and `AbortSignal`:

Node.js 14.17.0 adds experimental partial support for `AbortController` and `AbortSignal`.

Both constructors can be enabled globally using the `--experimental-abortcontroller` flag.

Additionally, several Node.js APIs have been updated to support `AbortSignal` for cancellation.
It is not mandatory to use the built-in constructors with them. Any spec-compliant third-party alternatives
should be compatible.

`AbortSignal` support was added to the following methods:

* `child_process.exec`
* `child_process.execFile`
* `child_process.fork`
* `child_process.spawn`
* `dgram.createSocket`
* `events.on`
* `events.once`
* `fs.readFile`
* `fs.watch`
* `fs.writeFile`
* `http.request`
* `https.request`
* `http2Session.request`
* The promisified variants of `setImmediate` and `setTimeout`
