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)) - [#&#8203;4389](https://togithub.com/mochajs/mocha/issues/4389): Refactoring: Consuming log-symbols alternate to code for win32 in reporters/base ([**@&#8203;MoonSupport**](https://togithub.com/MoonSupport)) #### 🎉 Enhancements - [#&#8203;4640](https://togithub.com/mochajs/mocha/issues/4640): Add new option `--dry-run` ([**@&#8203;juergba**](https://togithub.com/juergba)) #### 🐛 Fixes - [#&#8203;4128](https://togithub.com/mochajs/mocha/issues/4128): Fix: control stringification of error message ([**@&#8203;syeutyu**](https://togithub.com/syeutyu)) #### 🔩 Other - [#&#8203;4646](https://togithub.com/mochajs/mocha/issues/4646): Deprecate `Runner(suite: Suite, delay: boolean)` signature ([**@&#8203;juergba**](https://togithub.com/juergba)) - [#&#8203;4643](https://togithub.com/mochajs/mocha/issues/4643): Update production dependencies ([**@&#8203;juergba**](https://togithub.com/juergba)) </details> --- ### Configuration 📅 **Schedule**: "every 3 months on the first day of the month" (UTC). 🚦 **Automerge**: Disabled by config.
