I'm testing with ubuntu zesty and it's still at dovecot 2.2.25 so
where might I find the docs for the relevant changes in 2.2.27 that
will no doubt affect me in another month or three?

And would anyone have an example of how to use dovecot-pigeonhole
to call spamprobe as an external program in the current 2.2.25?

I've only been testing postfix/dovecot for a few weeks so I'm not
familiar with most of the docs or ecosystem in general.
