The PowerShell team blog http://blogs.msdn.com/b/powershell/archive/2015/02/13/new-and-improved-resource-kit.aspx details the new resources and bug fixes in wave 10 of the DSC resource kit. This is a much smaller release than the of late but includes new resources for initializing and formatting disks
One point the “small print” is important to note. This is the last release of these resource as a big zip file for download from the TechNet script gallery. In future these resources will only be available through the PowerShell gallery. Use Find-DscResource to discover the resources available in the gallery and Update-Module & Install-module to get the modules containing resources from the gallery.
