Sourced from mkdirp's changelog.

Changers Lorgs!

1.0

Full rewrite. Essentially a brand new module.

• Return a promise instead of taking a callback.
• Use native fs.mkdir(path, { recursive: true }) when available.
• Drop support for outdated Node.js versions. (Technically still works on Node.js v8, but only 10 and above are officially supported.)

0.x

Original and most widely used recursive directory creation implementation in JavaScript, dating back to 2010.
