   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.
   
   Contributed by Michaël Zasso in #41811.
   
   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.
   
   Contributed by Paolo Insogna in #41263.
   
   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.
   
   Contributed by Colin Ihrig in #42325.
   
   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.
   
   Contributed by Richard Lau in #42292,
   #42604 and #42659
   , and Michaël Zasso in #42105 and
   #42666.
   
   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 #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`.
   
   Contributed James Snell in #39062,
   and Antoine du Hamel in #42225.
