<summary>mochajs/mocha</summary>

### [`v9.0.1`](https://togithub.com/mochajs/mocha/blob/master/CHANGELOG.md#&#8203;901--2021-06-18)

[Compare Source](https://togithub.com/mochajs/mocha/compare/v9.0.0...v9.0.1)

#### 🔩 Other

-   [#&#8203;4657](https://togithub.com/mochajs/mocha/issues/4657): Browser: add separate bundle for modern browsers ([**@&#8203;juergba**](https://togithub.com/juergba))

We added a separate browser bundle `mocha-es2018.js` in javascript ES2018, as we skipped the transpilation down to ES5. This is an **experimental step towards freezing Mocha's support of IE11**.

-   [#&#8203;4653](https://togithub.com/mochajs/mocha/issues/4653): ESM: proper version check in `hasStableEsmImplementation` ([**@&#8203;alexander-fenster**](https://togithub.com/alexander-fenster))

### [`v9.0.0`](https://togithub.com/mochajs/mocha/blob/master/CHANGELOG.md#&#8203;900--2021-06-07)

[Compare Source](https://togithub.com/mochajs/mocha/compare/v8.4.0...v9.0.0)

#### 💥 Breaking Changes

-   [#&#8203;4633](https://togithub.com/mochajs/mocha/issues/4633): **Drop Node.js v10.x support** ([**@&#8203;juergba**](https://togithub.com/juergba))

-   [#&#8203;4635](https://togithub.com/mochajs/mocha/issues/4635): `import`-first loading of test files ([**@&#8203;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.

-   [#&#8203;4636](https://togithub.com/mochajs/mocha/issues/4636): Remove deprecated `utils.lookupFiles()` ([**@&#8203;juergba**](https://togithub.com/juergba))

-   [#&#8203;4638](https://togithub.com/mochajs/mocha/issues/4638): Limit the size of `actual`/`expected` for `diff` generation ([**@&#8203;juergba**](https://togithub.com/juergba))
