doas changes?

[Simon Parrer]

Hello together,
maybe any one can say me if there are changes on doas?
I ask because my doas say Abort trap when i try to use it with sysupgrade or 
pkg_add -u.
I do sysupgrade to OpenBSD 6.8-current (GENERIC.MP) #285: Wed Jan 20 17:31:16 
MST 2021.
Many Thanks and best regards Simon
