This is the first official stable release OctoTagger! Windows.zip contains OctoTagger and pywinlink, as well as an executable setup.exe for installing both. For Linux and OS X, the source code contains everything you need. Before installing, you have to make sure you have all the dependencies, which can be found on octotagger.co.
This release is the one we delivered for our final school project. It is very usable, but still more or less a prototype. Therefore, please beware that major compatibility breaking changes could be coming up soon.
