since F20 update, cron has stopped sending mail

[Steven Stern]

With F19, I got email from cron on all jobs that produced output.  I no
longer get those mails after upgrading to F20. I have verified that the
jobs are run.  There are no entries in /var/log/maillog for them.  Other
system tasks, not run through cron, send their emails as usual.

crontab has a "Mail to" line in it:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root

Any idea what I need to do to get my cron email restored?
