Thank you for reply. It exactly shows what I want to know if it is
before executing portupgade/portmaster. But I want to know same
information after packages are updated.

Currently I take following 4 steps.

# portsnap fetch update
# pkg version -L = > /tmp/updating-packages.log
# portupgrade -a
# pkg info -r `awk '{print $1}' /tmp/updating-packages.log`

I would like to merge step 2 and 4 if possible.
