Versioned static files

Hugo, being a static site generators, ends up being 100% static files.
This is awesome for CDNs that are able to serve those files very quickly.
Also it would be awesome for browser caching.

To make possible to use long time cache (both at CDN level and at browser level) for static files, the best way is to create some type of versioning for static files (probably the easyest one would be an md5).

Is this feature somehow supported? I looked in the documentation but I did not found anything.
Would this feature be supported in future?

  1. No, but there are good tools out there that fit nicely into the Hugo build process (Gulp, Grunt …)
  2. A big maybe.
