Latest is version 1.3 for the DS 250 Pro. As for how to get an updated version, please call support. They would be able to help you there. Also note that there are major changes to the profile going from version 1.2 or below to 1.3. You will have to get new profiles for the lights if you update to version 1.3.
I am not completely sure what the update entails. The ROMs have to be flashed clearly, but their might also be slight hardware differences as well. Best bet is to ask service to see if it is just as simply as flashing the ROMs or some a little more evolved.
As far as changes, the profiles are slightly different. The biggest addition is the ability to do split colors and gobos with the new version.
For glass, compressed air and some glass cleaner. For metal, just some compressed air. If you pull them out, just make sure you put them in the correct way again. This prevents failure.
