The JuliaOpt / JuMP (Julia for Mathematical Programming) team has been responsive and supportive. When I file a Github issue at a random hour, they respond in minutes. The quality of code and testing is outstanding, and frankly for a project started in academia that's rare. In the dynamic world of pre-1.0 Julia, they've set the standard for 3rd party libraries, accommodated deprecations from the language immediately as versions change, and overall driven the advancement of scientific computing. https://github.com/juliaopt/jump.jl https://github.com/juliaopt/jump.jl Edit: Here's a great example of the JuMP team debugging somebody's particular script, running it, and benchmarking it - all because somebody filed a Github issue. https://github.com/JuliaOpt/JuMP.jl/issues/614 https://github.com/JuliaOpt/JuMP.jl/issues/614
