**Documentation for this release can be found at [next.mochajs.org](https://next.mochajs.org)**!

Welcome [**@plroebuck**](https://github.com/plroebuck), [**@craigtaub**](https://github.com/craigtaub), & [**@markowsiak**](https://github.com/markowsiak) to the team!

## :boom: Breaking Changes

- [#3149](https://github.com/mochajs/mocha/issues/3149): **Drop Node.js v4.x support** ([**@outsideris**](https://github.com/outsideris))
- [#3556](https://github.com/mochajs/mocha/issues/3556): Changes to command-line options ([**@boneskull**](https://github.com/boneskull)):
  - `--grep` and `--fgrep` are now mutually exclusive; attempting to use both will cause Mocha to fail instead of simply ignoring `--grep`
  - `--compilers` is no longer supported; attempting to use will cause Mocha to fail with a link to more information
  - `-d` is no longer an alias for `--debug`; `-d` is currently ignored
  - [#3275](https://github.com/mochajs/mocha/issues/3275): `--watch-extensions` no longer implies `js`; it must be explicitly added ([**@TheDancingCode**](https://github.com/TheDancingCode))
- [#2908](https://github.com/mochajs/mocha/issues/2908): `tap` reporter emits error messages ([**@chrmod**](https://github.com/chrmod))
- [#2819](https://github.com/mochajs/mocha/issues/2819): When conditionally skipping in a `before` hook, subsequent `before` hooks _and_ tests in nested suites are now skipped ([**@bannmoore**](https://github.com/bannmoore))
- [#627](https://github.com/mochajs/mocha/issues/627): Emit filepath in "timeout exceeded" exceptions where applicable ([**@boneskull**](https://github.com/boneskull))
- [#3556](https://github.com/mochajs/mocha/issues/3556): `lib/template.html` has moved to `lib/browser/template.html` ([**@boneskull**](https://github.com/boneskull))
- [#2576](https://github.com/mochajs/mocha/issues/2576): An exception is now thrown if Mocha fails to parse or find a `mocha.opts` at a user-specified path ([**@plroebuck**](https://github.com/plroebuck))
- [#3458](https://github.com/mochajs/mocha/issues/3458): Instantiating a `Base`-extending reporter without a `Runner` parameter will throw an exception ([**@craigtaub**](https://github.com/craigtaub))
- [#3125](https://github.com/mochajs/mocha/issues/3125): For consumers of Mocha's programmatic API, all exceptions thrown from Mocha now have a `code` property (and some will have additional metadata). Some `Error` messages have changed. **Please use the `code` property to check `Error` types instead of the `message` property**; these descriptions will be localized in the future. ([**@craigtaub**](https://github.com/craigtaub))

## :fax: Deprecations

These are _soft_-deprecated, and will emit a warning upon use. Support will be removed in (likely) the next major version of Mocha:

- `-gc` users should use `--gc-global` instead
- Consumers of the function exported by `bin/options` should now use the `loadMochaOpts` or `loadOptions` (preferred) functions exported by the `lib/cli/options` module

Regarding the `Mocha` class constructor (from `lib/mocha`):

- Use property `color: false` instead of `useColors: false`
- Use property `timeout: false` instead of `enableTimeouts: false`

All of the above deprecations were introduced by [#3556](https://github.com/mochajs/mocha/issues/3556).

`mocha.opts` is now considered "legacy"; please prefer RC file or `package.json` over `mocha.opts`.

## :tada: Enhancements

Enhancements introduced in [#3556](https://github.com/mochajs/mocha/issues/3556):

- Mocha now supports "RC" files in JS, JSON, YAML, or `package.json`-based (using `mocha` property) format

  - `.mocharc.js`, `.mocharc.json`, `.mocharc.yaml` or `.mocharc.yml` are valid "rc" file names and will be automatically loaded
  - Use `--config /path/to/rc/file` to specify an explicit path
  - Use `--package /path/to/package.json` to specify an explicit `package.json` to read the `mocha` prop from
  - Use `--no-config` or `--no-package` to completely disable loading of configuration via RC file and `package.json`, respectively
  - Configurations are merged as applicable using the priority list:
    1. Command-line arguments
    1. RC file
    1. `package.json`
    1. `mocha.opts`
    1. Mocha's own defaults
  - Check out these [example config files](https://github.com/mochajs/mocha/tree/master/example/config)

- Node/V8 flag support in `mocha` executable:

  - Support all allowed `node` flags as supported by the running version of `node` (also thanks to [**@demurgos**](https://github.com/demurgos))
  - Support any V8 flag by prepending `--v8-` to the flag name
  - All flags are also supported via config files, `package.json` properties, or `mocha.opts`
  - Debug-related flags (e.g., `--inspect`) now _imply_ `--no-timeouts`
  - Use of e.g., `--debug` will automatically invoke `--inspect` if supported by running version of `node`

- Support negation of any Mocha-specific command-line flag by prepending `--no-` to the flag name

- Interfaces now have descriptions when listed using `--interfaces` flag

- `Mocha` constructor supports all options

- `--extension` is now an alias for `--watch-extensions` and affects _non-watch-mode_ test runs as well. For example, to run _only_ `test/*.coffee` (not `test/*.js`), you can do `mocha --require coffee-script/register --extensions coffee`.

- [#3552](https://github.com/mochajs/mocha/issues/3552): `tap` reporter is now TAP13-capable ([**@plroebuck**](https://github.com/plroebuck) & [**@mollstam**](https://github.com/mollstam))

- [#3428](https://github.com/mochajs/mocha/issues/3428): `xunit` reporter shows diffs ([**@mlucool**](https://github.com/mlucool))

- [#2529](https://github.com/mochajs/mocha/issues/2529): `Runner` now emits a `retry` event when tests are retried (reporters can listen for this) ([**@catdad**](https://github.com/catdad))

- [#2962](https://github.com/mochajs/mocha/issues/2962), [#3111](https://github.com/mochajs/mocha/issues/3111): In-browser notification support; warn about missing prereqs when `--growl` supplied ([**@plroebuck**](https://github.com/plroebuck))

## :bug: Fixes

- [#3265](https://github.com/mochajs/mocha/issues/3265): Fixes regression in "watch" functionality introduced in v5.0.2 ([@outsideris](https://github.com/outsideris))

# 5.0.3 / 2018-03-06

This patch features a fix to address a potential "low severity" [ReDoS vulnerability](https://snyk.io/vuln/npm:diff:20180305) in the [diff](https://npm.im/diff) package (a dependency of Mocha).

## :lock: Security Fixes

- [#3266](https://github.com/mochajs/mocha/pull/3266): Bump `diff` to v3.5.0 ([@anishkny](https://github.com/anishkny))

## :nut_and_bolt: Other

- [#3011](https://github.com/mochajs/mocha/issues/3011): Expose `generateDiff()` in `Base` reporter ([@harrysarson](https://github.com/harrysarson))

# 5.0.2 / 2018-03-05

This release fixes a class of tests which report as _false positives_. **Certain tests will now break**, though they would have previously been reported as passing. Details below. Sorry for the inconvenience!

## :bug: Fixes

- [#3226](https://github.com/mochajs/mocha/issues/3226): Do not swallow errors that are thrown asynchronously from passing tests ([@boneskull](https://github.com/boneskull)). Example:

  \```js
  it('should actually fail, sorry!', function (done) {
  // passing assertion
  assert(true === true);

  // test complete & is marked as passing
  done();

  // ...but something evil lurks within
  setTimeout(() => {
  throw new Error('chaos!');
  }, 100);
  });
  \```

  Previously to this version, Mocha would have _silently swallowed_ the `chaos!` exception, and you wouldn't know. Well, _now you know_. Mocha cannot recover from this gracefully, so it will exit with a nonzero code.

  **Maintainers of external reporters**: _If_ a test of this class is encountered, the `Runner` instance will emit the `end` event _twice_; you _may_ need to change your reporter to use `runner.once('end')` intead of `runner.on('end')`.

Mocha starts off 2018 right by again dropping support for _unmaintained rubbish_.

Welcome [@vkarpov15](https://github.com/vkarpov15) to the team!

## :boom: Breaking Changes

- **[#3148](https://github.com/mochajs/mocha/issues/3148): Drop support for IE9 and IE10** ([@Bamieh](https://github.com/Bamieh))
  Practically speaking, only code which consumes (through bundling or otherwise) the userland [buffer](https://npm.im/buffer) module should be affected. However, Mocha will no longer test against these browsers, nor apply fixes for them.

## :tada: Enhancements

## :boom: Breaking Changes

For more info, please [read this article](https://boneskull.com/mocha-v4-nears-release/).

### Compatibility

- [#3016](https://github.com/mochajs/mocha/issues/3016): Drop support for unmaintained versions of Node.js ([@boneskull](https://github.com/boneskull)):
  - 0.10.x
  - 0.11.x
  - 0.12.x
  - iojs (any)
  - 5.x.x
- [#2979](https://github.com/mochajs/mocha/issues/2979): Drop support for non-ES5-compliant browsers ([@boneskull](https://github.com/boneskull)):
  - IE7

### Default Behavior

- [#2879](https://github.com/mochajs/mocha/issues/2879): By default, Mocha will no longer force the process to exit once all tests complete. This means any test code (or code under test) which would normally prevent `node` from exiting will do so when run in Mocha. Supply the `--exit` flag to revert to pre-v4.0.0 behavior ([@ScottFreeCode](https://github.com/ScottFreeCode), [@boneskull](https://github.com/boneskull))

- [#2406](https://github.com/mochajs/mocha/issues/2406): Restore execution of nested `describe.only()` suites ([@not-an-aardvark](https://github.com/not-an-aardvark))

# 3.0.0 / 2016-07-31

## :boom: Breaking Changes

- :warning: Due to the increasing difficulty of applying security patches made within its dependency tree, as well as looming incompatibilities with Node.js v7.0, **Mocha no longer supports Node.js v0.8**.

- :warning: **Mocha may no longer be installed by versions of `npm` less than `1.4.0`.** Previously, this requirement only affected Mocha's development dependencies. In short, this allows Mocha to depend on packages which have dependencies fixed to major versions (`^`).

- `.only()` is no longer "fuzzy", can be used multiple times, and generally just works like you think it should. :joy:

- To avoid common bugs, when a test injects a callback function (suggesting asynchronous execution), calls it, _and_ returns a `Promise`, Mocha will now throw an exception:

  \```js
  const assert = require('assert');

  it('should complete this test', function (done) {
  return new Promise(function (resolve) {
  assert.ok(true);
  resolve();
  })
  .then(done);
  });
  \```

  The above test will fail with `Error: Resolution method is overspecified. Specify a callback *or* return a Promise; not both.`.

- When a test timeout value _greater than_ `2147483648` is specified in any context (`--timeout`, `mocha.setup()`, per-suite, per-test, etc.), the timeout will be _disabled_ and the test(s) will be allowed to run indefinitely. This is equivalent to specifying a timeout value of `0`. See [MDN](https://developer.mozilla.org/docs/Web/API/WindowTimers/setTimeout#Maximum_delay_value) for reasoning.

- The `dot` reporter now uses more visually distinctive characters when indicating "pending" and "failed" tests.

- Mocha no longer supports [component](https://www.npmjs.com/package/component).

- The long-forsaken `HTMLCov` and `JSONCov` reporters--and any relationship to the "node-jscoverage" project--have been removed.

- `spec` reporter now omits leading carriage returns (`\r`) in non-TTY environment.

## :tada: Enhancements

Thanks [**@entertainyou**](https://github.com/entertainyou), [**@SimenB**](https://github.com/SimenB), [**@just-paja**](https://github.com/just-paja) for the heads-up.

# 2.5.0 / 2016-05-23

This has been awhile coming! We needed to feel confident that the next release wouldn't break browser compatibility (e.g. the last few patch releases).

## Browser Tests in CI

We now run unit tests against PhantomJS v1.x and an assortment of browsers on [SauceLabs](https://saucelabs.com), including:

- Internet Explorer v8.0
- Chrome (latest)
- Firefox (latest)
- Safari (latest)
- Microsoft Edge (latest)

To accomplish this, we now run Mocha's unit tests (and a handful of integration tests) via [Karma](https://npmjs.com/package/karma) and a modified [karma-mocha](https://npmjs.com/package/karma-mocha). Along the way, we had to solve issue [#880](https://github.com/mochajs/mocha/issues/880) (apologies to [**@mderijcke**](https://github.com/mderijcke) and [**@sukima**](https://github.com/sukima) who had PRs addressing this), as well as replace most usages of [should](https://npmjs.com/package/should) with [expect.js](https://npmjs.com/package/expect.js) for IE8.

Going forward, when sending PRs, your code will _only_ run against PhantomJS v1.x (and not hit SauceLabs) [because security](https://docs.travis-ci.com/user/pull-requests/#Security-Restrictions-when-testing-Pull-Requests).

## Node.js 6.x

Node.js 6.x "just worked" before, but now it's in the CI matrix, so it's "officially" supported. Mocha _still retains support_ for Node.js 0.8.x.

## "Minor" Release

You'll see mostly bug fixes below, but also a couple features--as such, it's a "minor" release.
