Hello Peter,
It can, partially, but for the maintainers to know about your
changes
you need to file bug reports in bugzilla, I suggest also you have a
mono4 tracking bug for all the bugs to block so it's easy for people
to track the status and help out as it's a central location.
Good to know.
We will file the bugs and patches in Bugzilla, but it will take some time.
We will also update the package list on
https://fedoraproject.org/wiki/Changes/Mono_4.
Thanks for the help,
Timotheus
