dns.reverse() is documented with dns.resolve*() as always performing DNS
queries without using hosts file configuration. However, c-ares
ares_gethostbyaddr() honors the channel lookup order, which can include
the files source and cause reverse lookups to return entries from
/etc/hosts.
Configure c-ares resolver channels with ARES_OPT_LOOKUPS set to "b" so
getHostByAddr uses DNS/PTR lookups only. This keeps dns.reverse()
aligned with dns.resolve*() and preserves the distinction from
system-resolution APIs such as dns.lookup() and dns.lookupService().
This is preferable to documenting the current behavior because hosts-
file reverse lookup results are platform-dependent and expose hostent
alias semantics rather than DNS PTR record semantics.

Support for the 'node:' prefixed builtin module namespace was introduced
for `require()` expressions in Node v16.0.0, and backported to v14.18.0.
This was never supported in Node v15.x or chronologically older.
All of the current API history notes in the docs using 'node:' prefixed
module `require()`s happen to be documenting changes in Node versions
from before the time when support was first introduced.
This commit reverts those `require()`s in the history notes to be
un-prefixed. (They were incorrect as written; The prefixed `require()`s
would not work for those older Node versions.)
This change prevents the API history notes from inaccurately implying
'node:' prefixed builtin modules were introduced many Node versions ago,
or were `require()`-able with the 'node:' prefix in those Node versions.

fetch (experimental):
An experimental fetch API is available on the global scope by default.
The implementation is based upon https://undici.nodejs.org/#/,
an HTTP/1.1 client written for Node.js by contributors to the project.
Through this addition, the following globals are made available: `fetch`
, `FormData`, `Headers`, `Request`, `Response`.
Disable this API with the `--no-experimental-fetch` command-line flag.

HTTP Timeouts:
`server.headersTimeout`, which limits the amount of time the parser will
wait to receive the complete HTTP headers, is now set to `60000` (60
seconds) by default.
`server.requestTimeout`, which sets the timeout value in milliseconds
for receiving the entire request from the client, is now set to `300000`
(5 minutes) by default.
If these timeouts expire, the server responds with status 408 without
forwarding the request to the request listener and then closes the
connection.
Both timeouts must be set to a non-zero value to protect against
potential Denial-of-Service attacks in case the server is deployed
without a reverse proxy in front.

Test Runner module (experimental):
The `node:test` module facilitates the creation of JavaScript tests that
report results in TAP format. This module is only available under the
`node:` scheme.

Toolchain and Compiler Upgrades:
- Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux
(RHEL) 8 and are compatible with Linux distributions based on glibc
2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04.
- Prebuilt binaries for macOS now require macOS 10.15 or later.
- For AIX the minimum supported architecture has been raised from Power
7 to Power 8.
Prebuilt binaries for 32-bit Windows will initially not be available due
to issues building the V8 dependency in Node.js. We hope to restore
32-bit Windows binaries for Node.js 18 with a future V8 update.
Node.js does not support running on operating systems that are no longer
supported by their vendor. For operating systems where their vendor has
planned to end support earlier than April 2025, such as Windows 8.1
(January 2023) and Windows Server 2012 R2 (October 2023), support for
Node.js 18 will end at the earlier date.
Full details about the supported toolchains and compilers are documented
in the Node.js `BUILDING.md` file.

V8 10.1:
The V8 engine is updated to version 10.1, which is part of Chromium 101.
Compared to the version included in Node.js 17.9.0, the following new
features are included:
- The `findLast` and `findLastIndex` array methods.
- Improvements to the `Intl.Locale` API.
- The `Intl.supportedValuesOf` function.
- Improved performance of class fields and private class methods (the
initialization of them is now as fast as ordinary property stores).
The data format returned by the serialization API (`v8.serialize(value)`)
has changed, and cannot be deserialized by earlier versions of Node.js.
On the other hand, it is still possible to deserialize the previous
format, as the API is backwards-compatible.
Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657.
Web Streams API (experimental):
Node.js now exposes the experimental implementation of the Web Streams
API on the global scope. This means the following APIs are now globally
available:
- `ReadableStream`, `ReadableStreamDefaultReader`,
`ReadableStreamBYOBReader`, `ReadableStreamBYOBRequest`,
`ReadableByteStreamController`, `ReadableStreamDefaultController`,
`TransformStream`, `TransformStreamDefaultController`, `WritableStream`,
`WritableStreamDefaultWriter`, `WritableStreamDefaultController`,
`ByteLengthQueuingStrategy`, `CountQueuingStrategy`, `TextEncoderStream`,
`TextDecoderStream`, `CompressionStream`, `DecompressionStream`.

Main changes:
- Replace current HTML anchor generation to match
header anchor generation in Github markdown.
- Remove unnecessary double namespacing on generated anchors/links (E.G.
`esm.md#loaders` instead of `esm.md#esm_loaders`).
- Anchors/links are automatically prefixed with their respective modules
when concatenated for usage in `all.html`.
Benefits:
- All anchor links within and between markdown API docs actually work.
- Adding new anchor links no longer requires contributors to generate
the HTML docs first to look up the correct anchors.
- Anchors are much shorter.
- All previous anchor links are preserved by generating hidden legacy
anchors.

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`
