• Migrated from default to named export (see why here lukeed/klona#17):

ESM/TypeScript

- import isPlainObject from 'is-plain-object';
+ import { isPlainObject } from 'is-plain-object';

CommonJS

- const isPlainObject = require('is-plain-object');
+ const { isPlainObject } = require('is-plain-object');

• Added native ESM support via exports mapping

Reduced size and added type guide to ts definition (thanks to @lifeiscontent)

In this release Object.create(null) is considered as plain object as well.

In this release we provided module entry point. This may be breaking for some users who use bundlers.

Bower support was also dropped as not widely used these days.
