Old graphicall builds?

Hi. Recently I wanted to look for a specific build of graphicall. Apparently, is not up anymore and the older builds are not up in the new version, anyone knows where I can look for them?
I’m particualry curious about the GSOC 2016 curve improvements build.
I’ve seen this addon https://github.com/SavMartin/curve_cad does almost everything that build included but I’m curious to see what does that one or see if there was another interesting one.
