# History ## v2.1.0 (2019/12/26) * code now uses `standard` as linter * `var` has been replaced with `const` and `let` * code now executed in strict mode ## v2.0.0 (2016/11/05) * Buffers are now required to be passed as arguments. In 1.x, the arguments were assumed to be strings, and were always run through `String()`. * Starting with Node.js v6.6.0, use `crypto.timingSafeEqual()` (if available).
