- [#4633](https://github.com/mochajs/mocha/issues/4633): **Drop Node.js v10.x support** ([**@juergba**](https://github.com/juergba))

- [#4635](https://github.com/mochajs/mocha/issues/4635): `import`-first loading of test files ([**@giltayar**](https://github.com/giltayar))

**Mocha is going ESM-first!** This means that it will now use ESM `import(test_file)` to load the test files, instead of the CommonJS `require(test_file)`. This is not a problem, as `import` can also load most files that `require` does. In the rare cases where this fails, it will fallback to `require(...)`. This ESM-first approach is the next step in Mocha's ESM migration, and allows ESM loaders to load and transform the test file.

## 8.2.0 / 2020-10-16

The major feature added in v8.2.0 is addition of support for [*global fixtures*](https://mochajs.org/#global-fixtures).

While Mocha has always had the ability to run setup and teardown via a hook (e.g., a `before()` at the top level of a test file) when running tests in serial, Mocha v8.0.0 added support for parallel runs. Parallel runs are *incompatible* with this strategy; e.g., a top-level `before()` would only run for the file in which it was defined.

With [global fixtures](https://mochajs.org/#global-fixtures), Mocha can now perform user-defined setup and teardown *regardless* of mode, and these fixtures are guaranteed to run *once and only once*. This holds for parallel mode, serial mode, and even "watch" mode (the teardown will run once you hit Ctrl-C, just before Mocha finally exits). Tasks such as starting and stopping servers are well-suited to global fixtures, but not sharing resources--global fixtures do *not* share context with your test files (but they do share context with each other).

Here's a short example of usage:

```js
// fixtures.js

// can be async or not
exports.mochaGlobalSetup = async function () {
  this.server = await startSomeServer({port: process.env.TEST_PORT});
  console.log(`server running on port ${this.server.port}`);
};

exports.mochaGlobalTeardown = async function () {
  // the context (`this`) is shared, but not with the test files
  await this.server.stop();
  console.log(`server on port ${this.server.port} stopped`);
};

// this file can contain root hook plugins as well!
// exports.mochaHooks = { ... }
```

Fixtures are loaded with `--require`, e.g., `mocha --require fixtures.js`.

For detailed information, please see the [documentation](https://mochajs.org/#global-fixtures) and this handy-dandy [flowchart](https://mochajs.org/#test-fixture-decision-tree-wizard-thing) to help understand the differences between hooks, root hook plugins, and global fixtures (and when you should use each).

### :tada: Enhancements

- [#4308](https://github.com/mochajs/mocha/issues/4308): Support run-once [global setup & teardown fixtures](https://mochajs.org/#global-fixtures) ([**@boneskull**](https://github.com/boneskull))

*For implementors of custom reporters:*

- [#4409](https://github.com/mochajs/mocha/issues/4409): Parallel mode and custom reporter improvements ([**@boneskull**](https://github.com/boneskull)):
  - Support custom worker-process-only reporters (`Runner.prototype.workerReporter()`); reporters should subclass `ParallelBufferedReporter` in `mocha/lib/nodejs/reporters/parallel-buffered`
  - Allow opt-in of object reference matching for "sufficiently advanced" custom reporters (`Runner.prototype.linkPartialObjects()`); use if strict object equality is needed when consuming `Runner` event data
  - Enable detection of parallel mode (`Runner.prototype.isParallelMode()`)

### :bug: Fixes

- [#4476](https://github.com/mochajs/mocha/issues/4476): Workaround for profoundly bizarre issue affecting `npm` v6.x causing some of Mocha's deps to be installed when `mocha` is present in a package's `devDependencies` and `npm install --production` is run the package's working copy ([**@boneskull**](https://github.com/boneskull))

## 8.1.0 / 2020-07-30

In this release, Mocha now builds its browser bundle with Rollup and Babel, which will provide the project's codebase more flexibility and consistency.

While we've been diligent about backwards compatibility, it's *possible* consumers of the browser bundle will encounter differences (other than an increase in the bundle size). If you *do* encounter an issue with the build, please [report it here](https://github.com/mochajs/mocha/issues/new?labels=unconfirmed-bug\&template=bug_report.md\&title=).

This release **does not** drop support for IE11.

### :bug: Fixes

- Fix missing `mocharc.json` in published package ([**@boneskull**](https://github.com/boneskull))

## 6.0.0-0 / 2019-01-01

**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))

## 5.0.4 / 2018-03-07

### :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

- [#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
