Anyway, I assume the patch submission requirement (mentioned on https://wiki.winehq.org/Summer_Of_Code) is still valid, right?
It looks like the page is outdated, because it refers to GSoC 2015.
I suggest the applicants who haven't submitted patches to Wine yet to work on it sooner rather than later.
Does it mean I need to submit a patch until 22 April? Are the patches to Wine Staging considered?
