Notable changes: New assert APIs The `assert` module now provides experimental `assert.match()` and `assert.doesNotMatch()` methods. They will validate that the first argument is a string and matches (or does not match) the provided regular expression This is an experimental feature. Ruben Bridgewater [nodejs#30929](nodejs#30929). Advanced serialization for IPC The `child_process` and `cluster` modules now support a `serialization` option to change the serialization mechanism used for IPC. The option can have one of two values: * `'json'` (default): `JSON.stringify()` and `JSON.parse()` are used. This is how message serialization was done before. * `'advanced'`: The serialization API of the `v8` module is used. It is based on the HTML structured clone algorithm. and is able to serialize more built-in JavaScript object types, such as `BigInt`, `Map`, `Set` etc. as well as circular data structures. Anna Henningsen [nodejs#30162](nodejs#30162). CLI flags The new `--trace-exit` CLI flag makes Node.js print a stack trace whenever the Node.js environment is exited proactively (i.e. by invoking the `process.exit()` function or pressing Ctrl+C). legendecas [nodejs#30516](nodejs#30516). ___ The new `--trace-uncaught` CLI flag makes Node.js print a stack trace at the time of throwing uncaught exceptions, rather than at the creation of the `Error` object, if there is any. This option is not enabled by default because it may affect garbage collection behavior negatively. Anna Henningsen [nodejs#30025](nodejs#30025). ___ The `--disallow-code-generation-from-strings` V8 CLI flag is now whitelisted in the `NODE_OPTIONS` environment variable. Shelley Vohr [nodejs#30094](nodejs#30094). New crypto APIs For DSA and ECDSA, a new signature encoding is now supported in addition to the existing one (DER). The `verify` and `sign` methods accept a `dsaEncoding` option, which can have one of two values: * `'der'` (default): DER-encoded ASN.1 signature structure encoding `(r, s)`. * `'ieee-p1363'`: Signature format `r || s` as proposed in IEEE-P1363. Tobias Nießen [nodejs#29292](nodejs#29292). ___ A new method was added to `Hash`: `Hash.prototype.copy`. It makes it possible to clone the internal state of a `Hash` object into a new `Hash` object, allowing to compute the digest between updates. Ben Noordhuis [nodejs#29910](nodejs#29910). Dependency updates libuv was updated to 1.34.0. This includes fixes to `uv_fs_copyfile()` and `uv_interface_addresses()` and adds two new functions: `uv_sleep()` and `uv_fs_mkstemp()`. Colin Ihrig [nodejs#30783](nodejs#30783). ___ V8 was updated to 7.8.279.23. This includes performance improvements to object destructuring, RegExp match failures and WebAssembly startup time. The official release notes are available at https://v8.dev/blog/v8-release-78. Michaël Zasso [nodejs#30109](nodejs#30109). New EventEmitter APIs The new `EventEmitter.on` static method allows to async iterate over events. Matteo Collina [nodejs#27994](nodejs#27994). ___ It is now possible to monitor `'error'` events on an `EventEmitter` without consuming the emitted error by installing a listener using the symbol `EventEmitter.errorMonitor`. Gerhard Stoebich [nodejs#30932](nodejs#30932). ___ Using `async` functions with event handlers is problematic, because it can lead to an unhandled rejection in case of a thrown exception. The experimental `captureRejections` option in the `EventEmitter` constructor or the global setting change this behavior, installing a `.then(undefined, handler)` handler on the `Promise`. This handler routes the exception asynchronously to the `Symbol.for('nodejs.rejection')` method if there is one, or to the `'error'` event handler if there is none. Setting `EventEmitter.captureRejections = true` will change the default for all new instances of `EventEmitter`. This is an experimental feature. Matteo Collina [nodejs#27867](nodejs#27867). Performance Hooks are no longer experimental The `perf_hooks` module is now considered a stable API. legendecas [nodejs#31101](nodejs#31101). Introduction of experimental WebAssembly System Interface (WASI) support A new core module, `wasi`, is introduced to provide an implementation of the [WebAssembly System Interface](https://wasi.dev/) specification. WASI gives sandboxed WebAssembly applications access to the underlying operating system via a collection of POSIX-like functions. This is an experimental feature.
