# FAQ ### Looking for free support? http://support.iris-go.com https://kataras.rocket.chat/channel/iris ### Looking for previous versions? https://github.com/kataras/iris#version ### 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`. For further installation support, please click [here](http://support.iris-go.com/d/16-how-to-install-iris-web-framework). ### About our new home page http://iris-go.com Thanks to [Santosh Anand](https://github.com/santoshanand) the http://iris-go.com has been upgraded and it's really awesome!
