 ## :boom: Breaking Changes
 
-- #4633: **Drop Node.js v10.x support** (@juergba)
+- [#4633](https://github.com/mochajs/mocha/issues/4633): **Drop Node.js v10.x support** ([**@juergba**](https://github.com/juergba))
 
-- #4635: `import`-first loading of test files (@giltayar)
+- [#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.
