v3.0.0

This major release has been a long time coming! We've been saving up breaking changes for a while now, waiting for the ESLint v7 release which we knew would deprecate support for node version 8.

Due to our weekly release cadence, this major release mostly contains breaking changes!

Breaking Changes

Dropped support for Node version 8 (#1420)

In line with ESLint v7 - we've also dropped explicit support for node version 8. This version of node has been end of life since 2019-12-31. We no longer test against the version, so we provide no guarantees about whether or not future versions of our tooling will work on it.

Dropped support for TypeScript 3.2 (#2004)

Old TS versions cause us maintenance pain as we work on integrating tightly with the TypeScript APIs for performance and stability reasons.

As such we've updated our required TS version range to require a minimum of >=3.3.1.

Each version of TS brings bugfixes and features, but most importantly they bring performance improvements. TS 3.9 is releasing with a host of performance improvements that will improve both your build times, and your lint times - so you should endeavour to upgrade if you can. We cannot provide any guarantees around the performance of old TS versions.

Configs

We've updated all of our configs! We've added new rules, old rules, and removed some stylistic rules.

Check out the linked issues for more information about added/removed rules:

• eslint-recommended config (#1273)
• recommended config (#1423)
• recommended-requiring-typechecking (#1423)

Additionally, both of the recommended and recommended-requiring-typechecking sets now inherit from the eslint-recommended set. We noticed that the majority of the time, users were using the sets in tandem, so this just removes one line of config for everyone.

I.e. you can now do the following:

 extends: [
   "recommended",
-  "plugin:@typescript-eslint/eslint-recommended",
</tr></table> ... (truncated)
