I tested this version very carefully.
I did two upgrades following the manual, did a new installation using vagrant (https://gitlab.fechner.net/mfechner/Gitlab-vagrant) which was created by swills.
Everything is fine.
Oh to mention I tested also this list of ports to make sure the rubygem-rdoc update does not break anything:
# Test all port depending on rubygem-rdoc
# grep rubygem-rdoc INDEX-11 |cut -f1 -d\|
