v0.12.0

• Refactors processor core retrieval

!! Breaking change !!

In the past we've left poorly-named fields (like Id instead of ID) in the structs in case people were using the old names and then removed them after a deprecation period. However, in this release, the old ProcessorCore.Index field really was confusing and wrong: it stated that it was the zero-based index of the core on the physical processor package, but that was incorrect. In actuality, ProcessorCore.Index was one of the zero-based indexes of a logical processor associated with the physical core

Because of this, we have removed the ProcessorCore.Index field entirely. If you were using the ProcessorCore.Index field in your code, you should change to use the (correct) ProcessorCore.ID field to refer to the processor core.

Bug fixes

• Windows block devices: Name gathering now looks for "ssd" in Caption field to determine SSD drive type (#177). Remove unnecessary "/dev" prefix (#165)

Features

• Windows support (@KingRial, #9): CPU, memory, block, chassis, bios, product and network modules now supported on Windows.
• ghw.Disk.IsRemovable (@thetravischannel): Added new boolean attribute to ghw.Disk struct to represent if the disk drive is removable.
• Diagnostic snapshot (@jaypipes, #66): Added new ghw-snapshot command (currently Linux-only) that builds a static filesystem snapshot into a tarball and a script (hack/run-against-snapshot.sh) that will mount the snapshot in a Docker container and run ghwc against it for testing/diagnostic purposes
