v0.4.0 is a significant milestone for dep. It removes the dep prune command, absorbing its behavior entirely into dep ensure, with additional granular controls. This is an immediate boon for users' workflows, but it also unblocks the path to finishing essential parts of dep's design.

It is strongly recommended that you update your Gopkg.toml to include the new pruning directives as soon as you update to this new version of dep. For most projects, adding this to Gopkg.toml will be fine:

[prune]
  unused-packages = true
  go-tests = true

This will do everything dep prune used to, and more, with fewer bugs.

Less verbose, but equally exciting news: dep init now supports automated conversions from govendor and glock!

Finally, this release includes a new, detailed documentation site!
