2019-10-22, Version 13.0.0 (Current)

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).
    #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).
    #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).
    #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).
    #29622
* child_process:
  * `ChildProcess._channel` (DEP0129) is now a Runtime deprecation
    (cjihrig).
    #27949
* console:
  * The output `console.timeEnd()` and `console.timeLog()` will now
    automatically select a suitable time unit instead of always using
    milliseconds (Xavier Stouder).
    #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).
    #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).
    #26211
* fs:
  * The undocumented method `FSWatcher.prototype.start()` was removed
    (Lucas Holmquist).
    #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).
    #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).
    #26572
* http:
  * Aborted requests no longer emit the `end` or `error` events after
    `aborted` (Robert Nagy).
    #27984
    #20077
  * Data will no longer be emitted after a socket error (Robert Nagy).
    #28711
  * The legacy HTTP parser (previously available under the
    `--http-parser=legacy` flag) was removed (Anna Henningsen).
    #29589
  * The `host` option for HTTP requests is now validated to be a string
    value (Giorgos Ntemiris).
    #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).
    #29015
* http, http2:
  * The default server timeout was removed (Ali Ijaz Sheikh).
    #27558
  * Brought 425 status code name into accordance with RFC 8470. The name
    changed from "Unordered Collection" to "Too Early" (Sergei Osipov).
    #29880
* lib:
  * The `error.errno` property will now always be a number. To get the
    string value, use `error.code` instead (Joyee Cheung).
    #28140
* module:
  * `module.createRequireFromPath()` is deprecated. Use
    `module.createRequire()` instead (cjihrig).
    #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).
    #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.
