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

### [`v8.2.0`](https://togithub.com/mochajs/mocha/blob/HEAD/CHANGELOG.md#820--2020-10-16)
[Compare Source](https://togithub.com/mochajs/mocha/compare/v8.1.3...v8.2.0)
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).

- 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()`)

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://togithub.com/mochajs/mocha/issues/new?labels=unconfirmed-bug\&template=bug_report.md\&title=).
This release **does not** drop support for IE11.

In this major release, Mocha adds the ability to *run tests in parallel*. Better late than never! Please note the **breaking changes** detailed below.
Let's welcome [**@giltayar**](https://togithub.com/giltayar) and [**@nicojs**](https://togithub.com/nicojs) to the maintenance team!
#### :boom: Breaking Changes
- [#4164](https://togithub.com/mochajs/mocha/issues/4164): **Mocha v8.0.0 now requires Node.js v10.12.0 or newer.** Mocha no longer supports the Node.js v8.x line ("Carbon"), which entered End-of-Life at the end of 2019 ([**@UlisesGascon**](https://togithub.com/UlisesGascon))
- [#4175](https://togithub.com/mochajs/mocha/issues/4175): Having been deprecated with a warning since v7.0.0, **`mocha.opts` is no longer supported** ([**@juergba**](https://togithub.com/juergba))
:sparkles: **WORKAROUND:** Replace `mocha.opts` with a [configuration file](https://mochajs.org/#configuring-mocha-nodejs).
- [#4260](https://togithub.com/mochajs/mocha/issues/4260): Remove `enableTimeout()` (`this.enableTimeout()`) from the context object ([**@craigtaub**](https://togithub.com/craigtaub))
:sparkles: **WORKAROUND:** Replace usage of `this.enableTimeout(false)` in your tests with `this.timeout(0)`.
- [#4315](https://togithub.com/mochajs/mocha/issues/4315): The `spec` option no longer supports a comma-delimited list of files ([**@juergba**](https://togithub.com/juergba))
:sparkles: **WORKAROUND**: Use an array instead (e.g., `"spec": "foo.js,bar.js"` becomes `"spec": ["foo.js", "bar.js"]`).
- [#4309](https://togithub.com/mochajs/mocha/issues/4309): Drop support for Node.js v13.x line, which is now End-of-Life ([**@juergba**](https://togithub.com/juergba))
- [#4282](https://togithub.com/mochajs/mocha/issues/4282): `--forbid-only` will throw an error even if exclusive tests are avoided via `--grep` or other means ([**@arvidOtt**](https://togithub.com/arvidOtt))
- [#4223](https://togithub.com/mochajs/mocha/issues/4223): The context object's `skip()` (`this.skip()`) in a "before all" (`before()`) hook will no longer execute subsequent sibling hooks, in addition to hooks in child suites ([**@juergba**](https://togithub.com/juergba))
- [#4178](https://togithub.com/mochajs/mocha/issues/4178): Remove previously soft-deprecated APIs ([**@wnghdcjfe**](https://togithub.com/wnghdcjfe)):
- `Mocha.prototype.ignoreLeaks()`
- `Mocha.prototype.useColors()`
- `Mocha.prototype.useInlineDiffs()`
- `Mocha.prototype.hideDiff()`
