### Should I upgrade my Iris?

Developers are not forced to upgrade if they don't really need it. Upgrade whenever you feel ready.
> Iris uses the [vendor directory](https://docs.google.com/document/d/1Bz5-UB7g2uPBdOx-rw5t9MxJwkfpx90cqG9AFL0JAYo) feature, so you get truly reproducible builds, as this method guards against upstream renames and deletes.

**How to upgrade**: Open your command-line and execute this command: `go get -u github.com/kataras/iris`.
