Keith, I just read a note from Dave concerning illness in his family in the "Please Consider a Donation to BBS" at the top of this page. He posted this about a half hour ago.
"My mom made it through and is at home recovering.
Her prognosis is good...however, there are still some challenges ahead.
I am hopeful she can return to independent living in the near future.
I will be tied up assisting her and this may cause further nominal update delays."
He likely has had his hands full caring for his mother lately.
