After a long gap from the last release of WinDBG, the debugger team have released an update. Note that this is a preview or beta release however in my experience such releases from the debugger team are rock solid and as stable as "proper" releases. Also, the installation impact of the debugger package on a system is fairly minimal so if you have a problem with it just uninstall and install a previous release.
