9.0.1 / 2021-06-18

:nut_and_bolt: Other

• #4657: Browser: add separate bundle for modern browsers (@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.

9.0.0 / 2021-06-07

:boom: Breaking Changes

• #4633: Drop Node.js v10.x support (@juergba)

• #4635: import-first loading of test files (@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.
