# 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 - Drop support for outdated Node.js versions.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.
