### Version 1.4.1 release
* Using the versioned gstatic.com WASM and Javascript decoders is now
* Using the versioned www.gstatic.com WASM and Javascript decoders is now
recommended. To use v1.4.1, use this URL:
* https://www.gstatic.com/draco/versioned/decoders/1.4.1/*
* Replace the * with the files to load. E.g.
* https://gstatic.com/draco/versioned/decoders/1.4.1/draco_decoder.js
* https://www.gstatic.com/draco/versioned/decoders/1.4.1/draco_decoder.js
* This works with the v1.3.6 and v1.4.0 releases, and will work with future
Draco releases.
