DVTool version 2.1 is now available for the DV3K Dongle. You can go to http://www.dv3kdongle.com and click on the Installation tab for instructions for downloading/installing for Windows or Mac. The Linux version should follow shortly.
This version will also work with the DV Dongle. The only changes between 2.0 and 2.1 are for DV3K Dongle support so upgrading is not necessary for DV Dongle users.
The reflectors are running new code that supports the new DV3K Dongle. Dplus with DV3K support for the gateways should be released this weekend and it will then be up to the gateway admins to install the new version which is required for DV3K support.
