Notable changes:
* Experimental support for building Node.js with Python 3 is improved.
* ICU time zone data is updated to version 2019c. This fixes the date
offset in Brazil.
PR-URL: https://github.com/nodejs/node/issues/30352
Notable changes:
* assert:
* If the validation function passed to `assert.throws()` or
`assert.rejects()` returns a value other than `true`, an assertion
error will be thrown instead of the original error to highlight the
programming mistake (Ruben Bridgewater).
https://github.com/nodejs/node/pull/28263
* If a constructor function is passed to validate the instance of
errors thrown in `assert.throws()` or `assert.reject()`, an
assertion error will be thrown instead of the original error
(Ruben Bridgewater).
https://github.com/nodejs/node/pull/28263
* build:
* Node.js releases are now built with default full-icu support. This
means that all locales supported by ICU are now included and
Intl-related APIs may return different values than before
(Richard Lau).
https://github.com/nodejs/node/pull/29887
* The minimum Xcode version supported for macOS was increased to 10.
It is still possible to build Node.js with Xcode 8 but this may no
longer be the case in a future v13.x release (Michael Dawson).
https://github.com/nodejs/node/pull/29622
* child_process:
* `ChildProcess._channel` (DEP0129) is now a Runtime deprecation
(cjihrig).
https://github.com/nodejs/node/pull/27949
* console:
* The output `console.timeEnd()` and `console.timeLog()` will now
automatically select a suitable time unit instead of always using
milliseconds (Xavier Stouder).
https://github.com/nodejs/node/pull/29251
* deps:
* The V8 engine was updated to version 7.8. This includes performance
improvements to object destructuring, memory usage and WebAssembly
startup time (Myles Borins).
https://github.com/nodejs/node/pull/29694)
* domain:
* The domain's error handler is now executed with the active domain
set to the domain's parent to prevent inner recursion
(Julien Gilli).
https://github.com/nodejs/node/pull/26211
* fs:
* The undocumented method `FSWatcher.prototype.start()` was removed
(Lucas Holmquist).
https://github.com/nodejs/node/pull/29905
* Calling the `open()` method on a `ReadStream` or `WriteStream` now
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).
https://github.com/nodejs/node/pull/26572
* http:
* Aborted requests no longer emit the `end` or `error` events after
`aborted` (Robert Nagy).
https://github.com/nodejs/node/pull/27984https://github.com/nodejs/node/pull/20077
* Data will no longer be emitted after a socket error (Robert Nagy).
https://github.com/nodejs/node/pull/28711
* The legacy HTTP parser (previously available under the
`--http-parser=legacy` flag) was removed (Anna Henningsen).
https://github.com/nodejs/node/pull/29589
* The `host` option for HTTP requests is now validated to be a string
value (Giorgos Ntemiris).
https://github.com/nodejs/node/pull/29568
* The `request.connection` and `response.connection` properties are now
runtime deprecated. The equivalent `request.socket` and `response.socket`
should be used instead (Robert Nagy).
https://github.com/nodejs/node/pull/29015
* http, http2:
* The default server timeout was removed (Ali Ijaz Sheikh).
https://github.com/nodejs/node/pull/27558
* Brought 425 status code name into accordance with RFC 8470. The name
changed from "Unordered Collection" to "Too Early" (Sergei Osipov).
https://github.com/nodejs/node/pull/29880
* lib:
* The `error.errno` property will now always be a number. To get the
string value, use `error.code` instead (Joyee Cheung).
https://github.com/nodejs/node/pull/28140
* module:
* `module.createRequireFromPath()` is deprecated. Use
`module.createRequire()` instead (cjihrig).
https://github.com/nodejs/node/pull/27951
* src:
* Changing the value of `process.env.TZ` will now clear the tz cache.
This affects the default time zone used by methods such as
`Date.prototype.toString` (Ben Noordhuis).
https://github.com/nodejs/node/pull/20026
* stream:
* The timing and behavior of streams was consolidated for a number of
edge cases. Please look at the individual commits below for more
information.

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)

* 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.
PR-URL: https://github.com/nodejs/node/pull/28040
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
