I remember their reps telling me that 6.3 is a HW change, but 6.2 is a SW bug fix to the 6.1. So if you send in a 6.1, it will become 6.2 not 6.3.
He told me the bug only effects SOME RDs, so if you don't have any problems with it, don't bother sending it in.
Then again, I have heard a lot of BS from them |
