ESLint v7.5.0 released

We just pushed ESLint v7.5.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.


Optional Chaining Support

Support for optional chaining has landed in ESLint!

const maybeProp = obj.first?.second;

The default parser and built-in rules will support this syntax when you enable parserOptions.ecmaVersion: 2020 in your configuration:

"parserOptions": {
"ecmaVersion": 2020

Deprecating id-blacklist

id-blacklist has been deprecated and replaced with id-denylist. We renamed id-blacklist to id-denylist in the previous release (v7.4.0), which unfortunately led to some unintended breakages in the ESLint ecosystem. In this release, we have added back the id-blacklist rule and have marked it as deprecated. If you are currently using id-blacklist, we recommend switching to id-denylist to ensure you receive bug fixes and updates to the rule in future releases.
