Fedora 25 will be shipping with golang 1.7.1. If you have been closely tracking the change proposal https://fedoraproject.org/wiki/Changes/golang1.7 you know :). By now go1.7 is in Fedora 25(and rawhide) for over one month.
To see extensive list of most important changes see upstream doc at https://tip.golang.org/doc/go1.7. From Fedora packaging side there is now new support for s390x, golang has been bootstrapped there.
Thanks to everyone working on this release in upstream and/or rebase in Fedora.
I don't plan on rebasing golang in any of the currently released releases of Fedora, but if you are interesting in getting the most recent version(or any in between) of golang you can either download binaries from upstream or you can check out my private COPR repositories(builds are done also for EPELs) https://copr.fedoraproject.org/coprs/jcajka/.
I'm also looking forward to https://youtu.be/pZoGMXy3NKk. Unfortunately it is still not in production in Fedora. So no official Fedora images with golang yet. So I have been playing with fedora(23/24, x86_64 only, sorry :( ) based docker images on docker hub in the mean time(inc. images with go1.7) https://hub.docker.com/r/jcajka/fedora-golang/. I would like to "make them in to official images" when it will be possible in Fedora thanks to the layered builds.
