I see upgrading of Docker as a high risk for 5.1, especially with the
indicators from Evgeniy - bugs found. I feel that we can see more bugs,
while we have less and less time (basically we don't) for fixing and
stabilizing 5.1.

Instead of fixing one bug with the risk of introducing many more, I would
suggest now to find a workaround for initial bug without docker upgrade.
Even manual instructions in release notes would work.

Thanks,
