Node.js 20.0.0 (64-bit)

What's new in this version:

Permission Model:
- Node.js now has an experimental feature called the Permission Model
- It allows developers to restrict access to specific resources during program execution, such as file system operations, child process spawning, and worker thread creation.
- The API exists behind a flag --experimental-permission which when enabled will restrict access to all available permissions.
-
- More information about the Permission Model can be found in the Node.js documentation
- The Permission Model was a contribution

Custom ESM loader hooks run on dedicated thread:
- ESM hooks supplied via loaders (--experimental-loader=foo.mjs) now run in a dedicated thread, isolated from the main thread
- This provides a separate scope for loaders and ensures no cross-contamination between loaders and application code
- Synchronous import.meta.resolve()
- In alignment with browser behavior, this function now returns synchronously
- Despite this, user loader resolve hooks can still be defined as async functions (or as sync functions, if the author prefers)
- Even when there are async resolve hooks loaded, import.meta.resolve will still return synchronously for application code

V8 11.3:
- The V8 engine is updated to version 11.3, which is part of Chromium 113

This version includes three new features to the JavaScript API:
- String.prototype.isWellFormed and toWellFormed
- Methods that change Array and TypedArray
- Resizable ArrayBuffer and growable SharedArrayBuffer
- RegExp v flag with set notation + properties of strings
- WebAssembly Tail Call
- The V8 update was a contribution

Stable Test Runner:
- The recent update to Node.js, version 20, includes an important change to the test_runner module. The module has been marked as stable after a recent update. Previously, the test_runner module was experimental, but this change marks it as a stable module that is ready for production use.

Ada 2.0:
- Node.js v20 comes with the latest version of the URL parser, Ada. This update brings significant performance improvements to URL parsing, including enhancements to the url.domainToASCII and url.domainToUnicode functions in node:url.
- Ada 2.0 has been integrated into the Node.js codebase, ensuring that all parts of the application can benefit from the improved performance. Additionally, Ada 2.0 features a significant performance boost over its predecessor, Ada 1.0.4, while also eliminating the need for the ICU requirement for URL hostname parsing.
- Preparing single executable apps now requires injecting a Blob
- Building a single executable app now requires injecting a blob prepared
- This opens up the possibility of embedding multiple co-existing resources into the SEA (Single Executable Apps).

Web Crypto API:
- Web Crypto API functions' arguments are now coerced and validated as per their WebIDL definitions like in other Web Crypto API implementations
- This further improves interoperability with other implementations of Web Crypto API
- This change was made

Official support for ARM64 Windows:
- Node.js now includes binaries for ARM64 Windows, allowing for native execution on the platform
- The MSI, zip/7z packages, and executable are available from the Node.js download site along with all other platforms
- The CI system was updated and all changes are now fully tested on ARM64 Windows, to prevent regressions and ensure compatibility
- ARM64 Windows was upgraded to tier 2 support

WASI version must now be specified:
- When new WASI() is called, the version option is now required and has no default value
- Any code that relied on the default for the version will need to be updated to request a specific version
- This change was made

Deprecations and Removals:
- [3bed5f11e0] - (SEMVER-MAJOR) url: runtime-deprecate url.parse() with invalid ports
- url.parse() accepts URLs with ports that are not numbers. This behavior might result in host name spoofing with unexpected input
- These URLs will throw an error in future versions of Node.js, as the WHATWG URL API does already
- Starting with Node.js 20, these URLS cause url.parse() to emit a warning
