what in fact did happen.  You don't know how to make a good report?  See

When starting an org-drill session, I expect the answer to the question
to be hidden.  Since my last update, I see question and answer at the
same time.

I tracked the problem down to commit 2520fd654a65fe607a8ca726d7fc8fb5be07d258.

In function org-drill-hide-subheadings-if the following call of org-map-entries 
is
used:

(org-map-entries
       (lambda ()
         (when (and (not (outline-invisible-p))
                    (> (org-current-level) drill-entry-level))
           (when (or (/= (org-current-level) (1+ drill-entry-level))
                        (funcall test))
             (hide-subtree))
           (push (point) drill-sections)))
       "" 'tree)
