I was experimenting with beta2 over the last week and was eagerly awaiting beta3. I installed beta3 and ran into two problems. The first was the "newlist" bug, which is now fixed. The second is that everytime "qrunner" is run by cron, an email is sent to root (via the mailman alias). Here is the text of that email:

Reading database ... Adding message to /home/mailman/archives/private/junk

Writing mail ... Writing /home/mailman/archives/private/junk/index.html ... Writing /home/mailman/archives/private/junk/threads.html ... Writing database ... 3 messages

I solved this for now by simply redirecting stdout to /dev/null in the crontab. This was not a problem with beta2. What changed?

BTW, I am using MHonArc as an external archiver, if it matters. However, I was also running MHonArc with beta2.

Despite these minor problems, I am very pleased with Mailman and am planning on running some real mail lists with beta3 very soon (unless something major blows up).
