+## Update Note
+
+This package is now pure ESM as of 2.0.0. (Details: https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c)
+
+With that upgrade, I had to remove the multi select component as its dependency does not support ESM. Please
+use the v1x version branch with CJS if you need that.
