The project has been around for about 9 years, and there is basically no development now. In the early days it was mostly a 2-person benevolent dictatorship, between Daniel and myself, playing gatekeeper to the project and doing collectively the majority of the development. The model is still that of a simple, small project: I am effectively the only maintainer, I push straight to master, no release branches. There is automated testing, CI, builds, etc. The reason it's not more elaborate is just that it never seemed like something more complex was needed. I suppose that, in 2007, workflow tools like Github, git or even Maven weren't around or nearly as advanced, so it was somewhat harder to collaborate.
