Breaking changes

There is only one breaking change in the v4.0.0 release. We've fixed the bug that caused ESLint to incorrectly mark the error position for multiline imports.

Previous behavior:

import {
// ----^ (start of the error)
    ComponentA
} from './components/component-a';
// -----------------------------^ (end of the error)

Fixed behavior:

import {
    ComponentA
} from './components/component-a';
// ----^ (start) ---------------^ (end)

How to migrate

You need to adjust your eslint-disable-next-line directives to match the new position.

For example, this directive:

// eslint-disable-next-line
import {
    ComponentA
} from './components/component-a';

Should be moved here:

import {
    ComponentA
// eslint-disable-next-line
} from './components/component-a';
