dovecot - Jan 2016 - how do I get the version of the pigeonhole-sieve plugin

Hello,

as may parts of the dovecot configuration docs refer to sieve and it's
specific versions, like

? how do I get the Pigeonhole version my local dovecot uses?
The package version number of the ubuntu package dovecot-sieve isn't telling
me
anything here, because it's bound to the dovecot version number.

What do I miss here?

Thank you.

Background: sieve_default_name seems to be the option I'm looking for,
but it doesn't work and since the dovecot does not seem to check the
configuration for unknown plugin keywords, I can't even tell if the option
is
recognised or not.

Pigeonhole releases are not always bound to a specific Dovecot release
(nearby versions usually also work). Release announcements contain the
Dovecot version they were released with. Pigeonhole version numbers
alone do not provide this information though.

Newer Pigeonhole releases add a version line to the dovecot -n output
and they log the version at startup when mail_debug is enabled.

Version history is as follows:
