This document discusses Elm, an awesome frontend language that is fast, small in size, has a friendly compiler, easy learning curve, and no runtime errors. It mentions upgrading from elm-package.json to elm.json, changes to Platform.Cmd and uncurry/curry/flip, and recommends trying out the Pilf library. It also thanks the reader and answers an FAQ question about the next Elm version that will likely be 0.19.1 or 0.20 but without a specific predicted release date.
