I was fixing with my project on Google code and as I remembered it you could have a download tab for compressed files with releases and so on. But I couldn't find the download tab, I referred to the "Getting started guide" for Google Code and there it was, a reference to the downloads tab!
But I still couldn't find it! After a while a come across this: http://google-opensource.blogspot.se/2013/05/a-change-to-google-code-download-service.html
People miss used it to much so it has been removed.... That's to bad, nice to have it all in one place. How ever.... Update needed on the "Getting started guide"!
