ooo... i just filed a bug on this, gonna give it a spin right now

[vinyar]

so, i just gave it a spin (and learned that it's very difficult to find the origin of the PR (or that i suck at github.com))
Berksfile:

source 'https://supermarket.chef.io'
cookbook 'powershell', git: 'https://github.com/eligible/powershell.git', ref: 'c0e1f8bbfc7adc7464e7cc321572dbb84fdb1341'
metadata

Warning (assuming that's the one you fixed) is still there:

       Deprecated features used!
         Using an LWRP provider by its name (WindowsFeatureDism) directly is no longer supported in Chef 12 and will be removed.  Use Chef::ProviderResolver.new(node, resource, action) instead. at 1 location:
           - C:\Users\vagrant\AppData\Local\Temp\kitchen\cookbooks\windows\resources\feature.rb:32:in `initialize'

       Chef Client finished, 0/1 resources updated in 03 seconds
       Finished converging <certification-wind2012-r2> (0m9.37s).
-----> Kitchen is finished. (0m11.90s)
