I've manually updated it for now. We need to keep an eye on it and ensure it's auto-updating now though, and if not, track down why.

Ok, it's still not auto-updating. Is the Drupal cron job set up correctly?

Drupal cron job is NOT set up correctly on our new server. I just checked, the last run was a week ago.

Update: just fixed crontab on the server, we should now be good to go.

Folks, bad news: I can't get the cron to work on the server. I edited the crontab; everything seems to be right, the command in there, when executed from bash, does the right thing. It's unfortunately simply not executed on the server on regular intervals. I'm over my head - can one of the server admins please take a look?
