Hello,
As previously agreed on epel-devel and by the EPEL Steering Committee, I have pushed the Mono 4.2 packages and packages depending on it to epel-testing on EL7.
These updates will sit in epel-testing for a significant period of time to allow adequate notice and time for testing. I hope to push them to stable at around the time when CentOS 7.3 is released.
Just to let everyone know, that we have Mono 4.2 in Epel7 now! https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2016-03fb3c1531
CentOS 7.3 is not released yet, but RHEL 7.3 is released already for a couple of weeks.
All the best, Timotheus
