I don't remember the version. I think it was the 2018.03 version on a
RPI-2. It hang during boot if I had an USB-stick in it. It tried to boot
from USB instead of SD.
I changed the uboot variables to not do a 'usb start', which restored the
old behaviour. I think a new feature is that it is now possible to boot
from USB but I'm not sure.
This is the content of my uboot.env on the SD-card (lines are
0-terminated).
