The list of "pull requests" for the kbin project is here. A developer makes a pull request when they've made some changes to their copy of the code, and are requesting that those same changes be made to the original main code of the project.
If you look at the list of "closed" pull requests, the ones with the purple icon are the ones that have been approved. This is a good way to check how active a project is.
