Major update breaking changes: - ESLint 7.0.0 (https://eslint.org/docs/user-guide/migrating-to-7.0.0) now includes .eslint.rc.js in its list, which is fine for us. Other changes are not applicable for us. - eslint-plugin-mocha (https://github.com/lo1tuma/eslint-plugin-mocha/blob/master/CHANGELOG.md#700-may-13-2020) drops support for ESLint <7, but this CL updates to 7+. Other changes are not applicable for us.
