I have the explanation for this.  By searching the code I would that a new option 
from imapd.conf was being used.  The new option is "username_tolower" and I have set 
it to "no" in my config and it seems OK now.

What surprises me is that a new option has been created and the default value is the 
opposite of the old behaviour.  On top of that there is no reference to it in the 
"changes" document.
