Major update of hashie? (2.0.5 -> 3.5.5)

Hi, any objection against updating of hashie from 2.0.5 to 3.5.5? I would update it on rawhide after upcoming Fedora branching (for F27+). There is no strict reason for it, I just have a software (occi-core), which claims specific requirement 'hashie >= 3.3.1', but it works fine with the current version 2.0.5. Dependencies of hashie are: rOCCI-server-0:1.1.9-2.fc26.src rubygem-chef-zero-0:2.2-4.fc26.src rubygem-occi-core-0:4.3.5-2.fc26.src rubygem-omniauth-0:1.3.1-2.fc26.src Only problematic seems to be chef-zero requiring 'hashie < 3'. The newer version on rubygems requires only 'hashie < 4.0 >= 2.0', so maybe it is only about relaxing it in the package. Frantisek
