Yes, it is unfortunate, but we are obliged to re-engineer the update mechanism to protect our customers and partners from the consequences of modified firmware and this will cause a small delay.
I personally didn't even considered installing the "fix" that was posted on the site, but to have to go through a dealer to get future updates is not possible for me because their none in my area. So I really hope this re-engineered update mechanism takes that into consideration (I know this is the case for a lot of folks).
Looking forward to the update (for the 861v4, DSP8K...) and continuing enjoyment of my M kit.
