0.13.0

[chris-rock]

This release includes a breaking API change for Windows. If you checked for a specific release version, it changed from Server 2012 R2 to 6.3.9600. This harmonizes the Windows version detection with our Unix detection.

The same Windows 2012 would return:

# old, not usable anymore
os[:name] == nil
os[:family] == "windows"
os[:release] == "Server 2012 R2"
os[:arch] == nil

# new result set, which is more specific
os[:name] == 'Windows Server 2012 R2 Datacenter'
os[:family] == "windows"
os[:release] == '6.3.9600'
os[:arch] == '64-bit'
