v15.0.0

Compare Source

We're super excited to announce standard 15!

As with every new major release, there are lots of new rules in 15.0.0 designed
to help catch bugs and make programmer intent more explicit. This release brings
support for ES 2021, the latest version of the ECMAScript specification, as well
as many quality-of-life improvements, including ESLint v7.

When you upgrade, consider running standard --fix to automatically format your
code to match the newly added rules.
