module. This wraps uv_metrics_info into
performance.uvMetricsInfo() function.

1. Enforce receiver checks on IDL interfaces.
2. Avoid prototype manipulation on constructing IDL interfaces with
`ReflectConstruct`.
3. `defineReplaceableAttribute` should create IDL getter/setter.
4. Corrected `PerformanceResourceTiming` to inherit the public interface
`PerformanceEntry` instead of the internal interface
`InternalPerformanceResourceTiming`.
5. `detail` is not a specified attribute on `PerfomanceEntry`. Node.js
specific extensions are moved to a subclass of `PerformanceEntry` as
`PerformanceNodeEntry`.

Add WebPerf API `performance.setResourceTimingBufferSize` and event
`'resourcetimingbufferfull'` support.
The resource timing entries are added to the global performance
timeline buffer automatically when using fetch. If users are not
proactively cleaning these events, it can grow without limit. Apply
the https://www.w3.org/TR/timing-entrytypes-registry/ default
resource timing buffer max size so that the buffer can be limited
to not grow indefinitely.

Some core modules can be loaded with or without the `node:` prefix.
Using the prefix disambiguates which specifiers refer to core modules.
This commit updates the docs to use the prefix everywhere a core module
is referenced.

Notable Changes:
Deprecations and Removals:
- (SEMVER-MAJOR) fs: runtime deprecate string coercion in `fs.write`,
`fs.writeFileSync`
(Livia Medeiros) (https://github.com/nodejs/node/pull/42607)
- (SEMVER-MAJOR) dns: remove `dns.lookup` and `dnsPromises.lookup`

- (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life
(Tobias Nießen) (https://github.com/nodejs/node/pull/41479)
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 https://github.com/nodejs/node/pull/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 https://github.com/nodejs/node/pull/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 https://github.com/nodejs/node/pull/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.

, and Michaël Zasso in https://github.com/nodejs/node/pull/42105 and
https://github.com/nodejs/node/pull/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 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.

* Runtime deprecate additional perf entry properties

* Disable the `buffered` option on PerformanceObserver,

Only entries with active observers are buffered.
* This does remove the user timing and timerify
trace events. Because the trace_events are still
considered experimental, those can be removed without
a deprecation cycle. They are removed to improve
performance and reduce complexity.
