The removal (and creation of a port) has been pre-announced in UPDATING
1 month ago. Packages are available for all supported FreeBSD vesions.

I did not think that another entry in UPDATING is required to note the
actual removal.

No MFC is planned - CTM shall be kept in base for all releases up to 12.x.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.
