[packman] Policy for Change log for Packman packaged applications?

[oldcpu]

Is it still standard Packman packager practice to update the rpm change
log together with rpms when they are repackaged/released again? or is it
only for major releases?

Has this policy changed because of the build service pushing out a high
frequency of updates?

I've noted many of the recent packman packaged rpm updates have no entry
in their change log explaining why there was a recent release/update.
