Notable changes:
Fixed distribution for native addon builds
This release fixes an issue introduced in Node.js v17.0.0, where some V8
headers were missing from the distributed tarball, making it impossible
to build native addons. These headers are now included.
https://github.com/nodejs/node/pull/40526
Fixed stream issues
* Fixed a regression in `stream.promises.pipeline`, which was introduced
in version 16.10.0, is fixed. It is now possible again to pass an
array of streams to the function.
https://github.com/nodejs/node/pull/40193
* Fixed a bug in `stream.Duplex.from`, which didn't work properly when
an async generator function was passed to it.

Notable Changes:
Experimental ESM Loader Hooks API:
Node.js ESM Loader hooks have been consolidated to represent the steps involved needed to facilitate future loader chaining:
1. `resolve`: `resolve` [+ `getFormat`]
2. `load`: `getFormat` + `getSource` + `transformSource`
For consistency, `getGlobalPreloadCode` has been renamed to `globalPreload`.
A loader exporting obsolete hook(s) will trigger a single deprecation warning (per loader) listing the errant hooks.

Notable changes
The legacy HTTP parser is runtime deprecated:
- The legacy HTTP parser, selected by the `--http-parser=legacy` command line
option, is deprecated with the pending End-of-Life of Node.js 10.x (where it
is the only HTTP parser implementation provided) at the end of April 2021. It
will now warn on use but otherwise continue to function and may be removed in
a future Node.js 12.x release.
- The default HTTP parser based on llhttp is not affected. By default it is
stricter than the now deprecated legacy HTTP parser. If interoperability with
HTTP implementations that send invalid HTTP headers is required, the HTTP
parser can be started in a less secure mode with the `--insecure-http-parser`
command line option.
ES Modules:
- ES Modules are now considered stable.
node-api:
- Updated to node-api version 8 and added an experimental API to allow
retrieval of the add-on file name.
New API's to control code coverage data collection:
- `v8.stopCoverage()` and `v8.takeCoverage()` have been added.
New API to monitor event loop utilization by Worker threads
- `worker.performance.eventLoopUtilization()` has been added.

Vulnerabilities fixed:
- CVE-2020-8265: use-after-free in TLSWrap (High)
Affected Node.js versions are vulnerable to a use-after-free bug in
its TLS implementation. When writing to a TLS enabled socket,
node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly
allocated WriteWrap object as first argument. If the DoWrite method
does not return an error, this object is passed back to the caller
as part of a StreamWriteResult structure. This may be exploited to
corrupt memory leading to a Denial of Service or potentially other
exploits
- CVE-2020-8287: HTTP Request Smuggling in nodejs
Affected versions of Node.js allow two copies of a header field in
a http request. For example, two Transfer-Encoding header fields.
In this case Node.js identifies the first header field and ignores
the second. This can lead to HTTP Request Smuggling
(https://cwe.mitre.org/data/definitions/444.html).
- CVE-2020-1971: OpenSSL - EDIPARTYNAME NULL pointer de-reference (High)
This is a vulnerability in OpenSSL which may be exploited through Node.js.

ECMAScript Modules - Experimental Warning Removal:
- module: remove experimental modules warning
(Guy Bedford) [#31974](https://github.com/nodejs/node/pull/31974)
In Node.js 13 we removed the need to include the --experimental-modules
flag, but when running EcmaScript Modules in Node.js, this would still
result in a warning ExperimentalWarning: The ESM module loader is
experimental.
As of Node.js 14 there is no longer this warning when using ESM in
Node.js. However, the ESM implementation in Node.js remains
experimental. As per our stability index: “The feature is not subject
to Semantic Versioning rules. Non-backward compatible changes or
removal may occur in any future release.” Users should be cautious when
using the feature in production environments.
Please keep in mind that the implementation of ESM in Node.js differs
from the developer experience you might be familiar with. Most
transpilation workflows support features such as optional file
extensions or JSON modules that the Node.js ESM implementation does not
support. It is highly likely that modules from transpiled environments
will require a certain degree of refactoring to work in Node.js. It is
worth mentioning that many of our design decisions were made with two
primary goals. Spec compliance and Web Compatibility. It is our belief
that the current implementation offers a future proof model to
authoring ESM modules that paves the path to Universal JavaScript.
Please read more in our documentation.
The ESM implementation in Node.js is still experimental but we do believe
that we are getting very close to being able to call ESM in Node.js
“stable”. Removing the warning is a huge step in that direction.

It is expected that there will be an ABI mismatch on ARM between the
Node.js binary and native addons. Native addons are only broken if they
interact with `std::shared_ptr`. This is expected to be fixed in a
later version of Node.js 14.

Notable changes:
Due to release process failures, Node.js v10.20.0 shipped with source
and header tarballs that did not properly match the final release
commit that was used to build the binaries. We recommend that Node.js
v10.20.0 not be used, particularly in any applications using native
add-ons or where compiling Node.js from source is involved.
Node.js v10.20.1 is a clean release with the correct sources and is
strongly recommended in place of v10.20.0.

Our documentation uses em dashes inconsistently. They are treated
inconsistently typographically too. (For example, they are sometimes
surrounded by spaces and sometimes not.) They are also often confused
with ordinary hyphens such as in the CHANGELOG, where they are
inadvertently mixed together in a single list. The difference is
not obvious in the raw markdown but is very noticeable when rendered,
appearing to be a typographical error (which it in fact is).
The em dash is never needed. There are always alternatives. Remove em
dashes entirely.

In Node.js 13.9.0 deps/zlib was switched to the chromium maintained
implementation. This change had the unforseen consequence of breaking
building from the tarballs we release as we were too aggressively
removing `unneccessary files` from the `deps/zlib` folder. This release
includes a patch that ensures that individuals will once again be able
to build Node.js from source.

Notable changes:
Node.js 12.16.0 included 6 regressions that are being fixed in this
release
**Accidental Unflagging of Self Resolving Modules**:
12.16.0 included a large update to the ESM implementation. One of the
new features, Self Referential Modules, was accidentally released
without requiring the `--experimental-modules` flag. This release is
being made to appropriately flag the feature.
**Process Cleanup Changed Introduced WASM-Related Assertion**:
A change during Node.js process cleanup led to a crash in combination
with specific usage of WASM. This has been fixed by partially reverted
said change. A regression test and a full fix are being worked on and
will likely be included in future 12.x and 13.x releases.
**Use Largepages Runtime Option Introduced Linking Failure**:
A Semver-Minor change to introduce `--use-largepages` as a runtime
option introduced a linking failure. This had been fixed in master but
regressed as the fix has not yet gone out in a Current release. The
feature has been reverted, but will be able to reland with a fix in a
future Semver-Minor release.
**Async Hooks was Causing an Exception When Handling Errors**:
Changes in async hooks internals introduced a case where an internal
api call could be called with undefined causing a process to crash. The
change to async hooks was reverted. A regression test and fix has been
proposed and the change could re land in a future Semver-Patch release
if the regression is reliably fixed.
**New Enumerable Read-Only Property on EventEmitter breaks @types/extend**
A new property for enumerating events was added to the EventEmitter
class. This broke existing code that was using the `@types/extend`
module for extending classses as `@types/extend` was attemping to write
over the existing field which the new change made read-only. As this is
the first property on EventEmitter that is read-only this feature could
be considered Semver-Major. The new feature has been reverted but could
re land in a future Semver-Minor release if a non breaking way of
applying it is found.
**Exceptions in the HTTP parser were not emitting an uncaughtException**
A refactoring to Node.js interanls resulted in a bug where errors in
the HTTP parser were not being emitted by
`process.on('uncaughtException')`. The fix to this bug has been
included in this release.
PR-URL: https://github.com/nodejs/node/pull/31781
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 [#30929](https://github.com/nodejs/node/pull/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 [#30162](https://github.com/nodejs/node/pull/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 [#30516](https://github.com/nodejs/node/pull/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 [#30025](https://github.com/nodejs/node/pull/30025).
___
The `--disallow-code-generation-from-strings` V8 CLI flag is now whitelisted in
the `NODE_OPTIONS` environment variable.
Shelley Vohr [#30094](https://github.com/nodejs/node/pull/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 [#29292](https://github.com/nodejs/node/pull/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 [#29910](https://github.com/nodejs/node/pull/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 [#30783](https://github.com/nodejs/node/pull/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 [#30109](https://github.com/nodejs/node/pull/30109).
New EventEmitter APIs
The new `EventEmitter.on` static method allows to async iterate over events.
Matteo Collina [#27994](https://github.com/nodejs/node/pull/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 [#30932](https://github.com/nodejs/node/pull/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 [#27867](https://github.com/nodejs/node/pull/27867).
Performance Hooks are no longer experimental
The `perf_hooks` module is now considered a stable API.
legendecas [#31101](https://github.com/nodejs/node/pull/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.

emits a runtime deprecation warning. The methods are supposed to be
internal and should not be called by user code (Robert Nagy).
https://github.com/nodejs/node/pull/29061
* `fs.read/write`, `fs.readSync/writeSync` and `fd.read/write` now
accept any safe integer as their `offset` parameter. The value of
`offset` is also no longer coerced, so a valid type must be passed
to the functions (Zach Bjornson).

This is a security release.
Notable changes:
Node.js, as well as many other implementations of HTTP/2, have been
found vulnerable to Denial of Service attacks.
See https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md
for more information.
Vulnerabilities fixed:
* CVE-2019-9511 “Data Dribble”: The attacker requests a large amount of
data from a specified resource over multiple streams. They manipulate
window size and stream priority to force the server to queue the data
in 1-byte chunks. Depending on how efficiently this data is queued,
this can consume excess CPU, memory, or both, potentially leading to a
denial of service.
* CVE-2019-9512 “Ping Flood”: The attacker sends continual pings to an
HTTP/2 peer, causing the peer to build an internal queue of responses.
Depending on how efficiently this data is queued, this can consume
excess CPU, memory, or both, potentially leading to a denial of
service.
* CVE-2019-9513 “Resource Loop”: The attacker creates multiple request
streams and continually shuffles the priority of the streams in a way
that causes substantial churn to the priority tree. This can consume
excess CPU, potentially leading to a denial of service.
* CVE-2019-9514 “Reset Flood”: The attacker opens a number of streams
and sends an invalid request over each stream that should solicit a
stream of RST_STREAM frames from the peer. Depending on how the peer
queues the RST_STREAM frames, this can consume excess memory, CPU,or
both, potentially leading to a denial of service.
* CVE-2019-9515 “Settings Flood”: The attacker sends a stream of
SETTINGS frames to the peer. Since the RFC requires that the peer
reply with one acknowledgement per SETTINGS frame, an empty SETTINGS
frame is almost equivalent in behavior to a ping. Depending on how
efficiently this data is queued, this can consume excess CPU, memory,
or both, potentially leading to a denial of service.
* CVE-2019-9516 “0-Length Headers Leak”: The attacker sends a stream of
headers with a 0-length header name and 0-length header value,
optionally Huffman encoded into 1-byte or greater headers. Some
implementations allocate memory for these headers and keep the
allocation alive until the session dies. This can consume excess
memory, potentially leading to a denial of service.
* CVE-2019-9517 “Internal Data Buffering”: The attacker opens the HTTP/2
window so the peer can send without constraint; however, they leave
the TCP window closed so the peer cannot actually write (many of) the
bytes on the wire. The attacker then sends a stream of requests for a
large response object. Depending on how the servers queue the
responses, this can consume excess memory, CPU, or both, potentially
leading to a denial of service.
* CVE-2019-9518 “Empty Frames Flood”: The attacker sends a stream of
frames with an empty payload and without the end-of-stream flag. These
frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The
peer spends time processing each frame disproportionate to attack
bandwidth. This can consume excess CPU, potentially leading to a
denial of service. (Discovered by Piotr Sikora of Google)

both, potentially leading to a denial of service.
* CVE-2019-9515 “Settings Flood”: The attacker sends a stream of
SETTINGS frames to the peer. Since the RFC requires that the peer
reply with one acknowledgement per SETTINGS frame, an empty SETTINGS
frame is almost equivalent in behavior to a ping. Depending on how
efficiently this data is queued, this can consume excess CPU, memory,
or both, potentially leading to a denial of service.
* CVE-2019-9516 “0-Length Headers Leak”: The attacker sends a stream of
headers with a 0-length header name and 0-length header value,
optionally Huffman encoded into 1-byte or greater headers. Some
implementations allocate memory for these headers and keep the
allocation alive until the session dies. This can consume excess
memory, potentially leading to a denial of service.
* CVE-2019-9517 “Internal Data Buffering”: The attacker opens the HTTP/2
window so the peer can send without constraint; however, they leave
the TCP window closed so the peer cannot actually write (many of) the
bytes on the wire. The attacker then sends a stream of requests for a
large response object. Depending on how the servers queue the
responses, this can consume excess memory, CPU, or both, potentially
leading to a denial of service.
* CVE-2019-9518 “Empty Frames Flood”: The attacker sends a stream of
frames with an empty payload and without the end-of-stream flag. These
frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The
peer spends time processing each frame disproportionate to attack
bandwidth. This can consume excess CPU, potentially leading to a
denial of service. (Discovered by Piotr Sikora of Google)

Notable changes:
* doc:
* The JSON variant of the API documentation is no longer experimental
(Rich Trott) https://github.com/nodejs/node/pull/27842.
* esm:
* JSON module support is always enabled under
`--experimental-modules`. The `--experimental-json-modules` flag
has been removed (Myles Borins)
https://github.com/nodejs/node/pull/27752.
* http,http2:
* A new flag has been added for overriding the default HTTP server
socket timeout (which is two minutes). Pass
`--http-server-default-timeout=milliseconds`
or `--http-server-default-timeout=0` to respectively change or
disable the timeout. Starting with Node.js 13.0.0, the timeout will
be disabled by default
(Ali Ijaz Sheikh) https://github.com/nodejs/node/pull/27704.
* inspector:
* Added an experimental `--heap-prof` flag to start the V8 heap
profiler on startup and write the heap profile to disk before exit
(Joyee Cheung) https://github.com/nodejs/node/pull/27596.
* stream:
* The `readable.unshift()` method now correctly converts strings to
buffers. Additionally, a new optional argument is accepted to
specify the string's encoding, such as `'utf8'` or `'ascii'`
(Marcos Casagrande) https://github.com/nodejs/node/pull/27194.
* v8:
* The object returned by `v8.getHeapStatistics()` has two new
properties: `number_of_native_contexts` and
`number_of_detached_contexts` (Yuriy Vasiyarov)
https://github.com/nodejs/node/pull/27933.

Notable changes:
* deps:
* Updated llhttp to 1.1.3. This fixes a bug that made Node.js' HTTP
parser refuse any request URL that contained the "|" (vertical bar)
character. https://github.com/nodejs/node/pull/27595
* tls:
* Added an `enableTrace()` method to `TLSSocket` and an `enableTrace`
option to `tls.createServer()`. When enabled, TSL packet trace
information is written to `stderr`. This can be used to debug TLS
connection problems. https://github.com/nodejs/node/pull/27497https://github.com/nodejs/node/pull/27376
* cli:
* Added a `--trace-tls` command-line flag that enables tracing of TLS
connections without the need to modify existing application code.
https://github.com/nodejs/node/pull/27497
* Added a `--cpu-prof-interval` command-line flag. It can be used to
specify the sampling interval for the CPU profiles generated by
`--cpu-prof`. https://github.com/nodejs/node/pull/27535
* module:
* Added the `createRequire()` method. It allows to create a require
function from a file URL object, a file URL string or an absolute
path string. The existing `createRequireFromPath()` method is now
deprecated https://github.com/nodejs/node/pull/27405.
* Throw on `require('./path.mjs')`. This is technically a breaking
change that should have landed with Node.js 12.0.0. It is necessary
to have this to keep the possibility for a future minor version to
load ES Modules with the require function.
https://github.com/nodejs/node/pull/27417
* repl:
* The REPL now supports multi-line statements using `BigInt` literals
as well as public and private class fields and methods.
https://github.com/nodejs/node/pull/27400
* The REPL now supports tab autocompletion of file paths with `fs`
methods. https://github.com/nodejs/node/pull/26648
* meta:
* Added Christian Clauss (https://github.com/cclauss) to
collaborators. https://github.com/nodejs/node/pull/27554

This is a security release. All Node.js users should consult the security
release summary at:
https://nodejs.org/en/blog/vulnerability/february-2019-security-releases/
for details on patched vulnerabilities.
Fixes for the following CVEs are included in this release:
* Node.js: Denial of Service with keep-alive HTTP connections
(CVE-2019-5739)
* Node.js: Slowloris HTTP Denial of Service with keep-alive
(CVE-2019-5737)
* OpenSSL: 0-byte record padding oracle (CVE-2019-1559)
Notable Changes:
* deps: OpenSSL has been upgraded to 1.0.2r which contains a fix for
CVE-2019-1559 (https://www.openssl.org/news/secadv/20190226.txt). Under
certain circumstances, a TLS server can be forced to respond differently to
a client if a zero-byte record is received with an invalid padding
compared to a zero-byte record with an invalid MAC. This can be used as the
basis of a padding oracle attack to decrypt data.
* http:
- Backport `server.keepAliveTimeout` to prevent keep-alive HTTP and HTTPS
connections remaining open and inactive for an extended period of time,
leading to a potential Denial of Service (DoS).
(CVE-2019-5739 / Timur Shemsedinov, Matteo Collina)
- Further prevention of "Slowloris" attacks on HTTP and HTTPS
connections by consistently applying the receive timeout set by
`server.headersTimeout` to connections in keep-alive mode. Reported by
Marco Pracucci (https://voxnest.com). (CVE-2019-5737 / Matteo Collina)
