What's new in this version:

- Fixed a problem with code signing on one of our KEXTs (this was caused by an update to Xcode that tried to take over management of code signatures, but which unfortunately doesn’t appear to work properly for us). This will cure problems some users are seeing on macOS Sierra (really, this time). Our apologies to those affected.
