Yampa is a mature and robust FRP implementation that has been used to create mobile, desktop, and web games and applications, including games that use devices like wiimotes and kinect, as well as free and commercial mobile games available on iTunes and Google Play. (For reference, see [1-4].)
This version includes documentation for all modules and all definitions. We have closed a total of 29 issues. Thanks to @ptvirgo for contributing to this release. A limitation of Haddock prevents us from achieving 100% coverage. Help with that would be appreciated [5, 6].
This version has been tested against all major GHC versions, from 7.6 to 8.4. A minor change in the low-level interface has triggered a major version bump (0.11). I would expect all projects that use Yampa to work by, at most, adapting the version constraints in the cabal files.
Everybody is welcome to collaborate. The github repo includes some simple issues especially suitable for beginners, and we are working on the next major version. We are also exploring different research ideas related to FRP, and actively look for research collaborators.
