Standard v9.0.0 Release Notes
Release Date: 2017-02-28 // about 7 years ago-
🚀 It's time for a new major version of
standard! As usual, this release contains a bunch of awesomeness to help you keep your code in tip-top shape!We've added several new rules designed to catch potential programmer errors (i.e. bugs), as well as rules to make programmer intent more explicit in certain circumstances.
🚀 This release continues our trend of tightening up rules so that, wherever possible, there's one "right" way to do things. This design goal is intended to reduce the time that teams and maintainers spend giving code review feedback in pull requests.
⬆️ When you upgrade, consider running
standard --fixto automatically fix some of the errors caught by the new rules in this version.✅ Note: If you use the Chai test framework, you will need to make some changes to ✅ your tests to improve their robustness. Read about the changes you need to make.
🆕 New features
