Release 1.8.0 is available from the Microsoft Download Center. It may not be visible yet when you search for it but it is there.
This release matches the update for Virtual Server 2005 R2 SP1 which was released to support Server 2008 and Vista SP1. Release 1.7.0 was supposed to match that update but despite our assumption that the build would not change, it eventually did. So 1.7.0 incorrectly matches this update with build 1.1.627. The build number of the Virtual Server update is 1.1.629.
So VMRCplus 1.8.0 comes with the binaries of 1.1.629 which reflect the released bits of the Virtual Server update.
It also contains minor fixes. One is the ability to clear the 'run VM under user account'. Another is the support for Undo disks in various location of the UI. Setting the Undo disks options could be confusing which could lead to unexpected or unwanted behavior of Virtual Server. Undo disks options have been removed and context sensitive menu items have been added as a replacement. Management of Undo options has been moved to power options.
The same changes can be found in the Console Manager UI under Control. Finally, the same changes have been made in the VM Properties UI.
