[Nmh-workers] Changelog policy

[Jon Steinhart]

Oh, since I'm probably about to go make some changes again, I had an email from
somebody a while ago who was upset that I wasn't updating the Changelog when
making changes.  I wasn't doing it because I thought that it was done
automatically.  What's the policy on this?  Is it supposed to be done
automatically and is something broken?  Should it be updated manually every
time a change is made?  Or is is updated manually before every release?
