Thanks for your bugreport.

This is indeed a undocumented change, sorry for this. We reworked the
hash sum checking code to use sha256 by default now and that caused
the issue.

Could you please describe in a bit more details where you get hit by
the problem? Is it a custom method ? I want to add a regression test
for the fix so some information how you trigger it would be helpful.

Thanks,
 Michael
