Meow 4 is finally out ✨

Highlights

• Requires Node.js 4 or higher.
• Changed how minimist options are specified. (See more below) https://github.com/sindresorhus/meow/commit/43401c39ee442db308288f50d6f213cd0e6e602c https://github.com/sindresorhus/meow/commit/554119b0af09cb33aea4e709c0572043cd00586d
• Disabled type inference by default. It can lead to some surprising behavior. Can be enabled again with the inferType option. https://github.com/sindresorhus/meow/commit/1662881674c6b243226314e35d46115ea66329ff
• Removed support for using an array in the help option. Just use a template literal. https://github.com/sindresorhus/meow/commit/c80321d2ec6733d502335edb29d173f12bbf1111
• Removed support for the pkg option accepting a string. https://github.com/sindresorhus/meow/commit/2d4d89043c41030d60ee9eb5130a4fa62935ca37
• Removed support for setting the help and version options to false. Instead, use the new autoHelp and autoVersion options. https://github.com/sindresorhus/meow/commit/59dda7a9caf8400ce602d2b1cf663aa1b35bdfca
• Uses exit code 2 when manually calling cli.showHelp() now. https://github.com/sindresorhus/meow/commit/6a32bbc3acc9c41068234d80188e9d2e865f50fa

Changed how minimist options are specified

In Meow v3 you specified minimist options top-level just like documented in the minimist readme. Now you specify them in a flags option, grouped by flag name instead of option type.

Before

const cli = meow(
	`
		Help text
	`,
	{
		boolean: [
			'unicorn'
		],
		string: [
			'fooBar'
		],
		alias: {
			u: 'unicorn'
		},
		default: {
			foobar: 'foo'
		}
	}
});

After

const cli = meow(
	`
		Help text
	`,
	flags: {
		unicorn: {
			type: 'boolean',
			alias: 'u'
		},
		fooBar: {
			type: 'string',
			default: 'foo'
		}
	}
});

I would strongly recommend specifying the type property whenever possible to reduce CLI argument parsing ambiguity.
