Hi Ed,

Thanks for the heads up.

Quick question: is there now an expectation that each time a port is
changed the timestamp should be updated?

I.e. If a port changes in a way which does not change the distfiles, are we
supposed to run "make makesum" again anyway to record it has changed?

Or is the timestamp only supposed to change when the port is updates /
distfiles change?

Regards,
Ben
