- Adding a note to UPDATING
- Adding a note to the history section of the manpage ctm.1
- Adding a message printed to STDERR to the ctm program
This version is meant for release in FreeBSD-12.0 and should remain in
FreeBSD-12 over its life-time.
A follow-up commit will remove ctm from -CURRENT after the MFC to 12
has happened.
