mocha - npm Package Versions

8.0.0 / 2020-06-10

Let's welcome @giltayar and @nicojs to the maintenance team!

:boom: Breaking Changes

• #4164: Mocha v8.0.0 now requires Node.js v10.12.0 or newer. Mocha no longer supports the Node.js v8.x line ("Carbon"), which entered End-of-Life at the end of 2019 (@UlisesGascon)

  :sparkles: WORKAROUND: Replace mocha.opts with a configuration file.
