As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date. At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).
GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825. GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD. It
does not support modern C and does not support arm64 or RISC-V.
Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.
So long, and thanks for all the fish.

ABI has change in between ncurses 5 or 6. While theorically ncurses 6 is buildable with
backward compatibility, I fail at building in a way where the application linked against
the previous version of ncurses are rendering properly.
Let's go on the new ABI which provides all the latest features.

Each entry in ObsoleteFiles.inc adds to the time `make delete-old` and
friends take to run. Perl was removed from the FreeBSD base system a
very long time ago (FreeBSD 5); source updates have not been supported
from that version for years.
Perl was a single component responsible for thousands of entries so
provides significant benefit with little effort/investigation required.
We could still use a more comprehensive cleanup to remove old entries.
Also add an UPDATING note (with wordsmithing by imp) indicating that
`make delete-old` is required along each step of a source upgrade from
an old, unsupported release.

It serves no useful purpose and wasn't as popular as its equally meritless
cousin, srandomdev(3).
Setting aside the problems with rand(3) in general, the problem with this
interface is that the seed isn't shared with the caller (other than by
attacking the output of the generator, which is trivial, but not a hallmark of
pleasant API design). The (arguable) utility of rand(3) or random(3) is as a
semi-fast simulation generator which produces consistent results from a given
seed. These are mutually at odd. Furthermore, sometimes people got the
mistaken impression that a high quality random seed meant a weak generator like
rand(3) or random(3) could be used for things like cryptographic key
generation. This is absolutely not so.
The API was never part of a standard and was not widely used in tree. Existing
in-tree uses have all been removed.
Possible replacement in out of tree codebases:
char buf[3];
time_t t;
time(t);
strftime(buf, sizeof(buf), "%S", gmtime(&t));
srand(atoi(buf));

A comment at the top of the file claimed that the file was grouped into
OLD_FILES, OLD_LIBS, then OLD_DIRS, but that hasn't been the case since
the mid-2000s. Delete the stale comment, add a new comment for the
historical split entries, and move the one more recent entry (from 2013)
to group it into a single logical change.
Add the manual page for sio(4) to ObsoleteFiles.inc, so that make delete-all

* Remove zpool_create_013_neg. FreeBSD doesn't have an equivalent of
Solaris's metadevices. GEOM would be the equivalent, but since all geoms
are the same from ZFS's perspective, this test would be redundant with
zpool_create_012_neg
* Remove zpool_create_014_neg. FreeBSD does not support swapping to regular

* Remove zpool_create_016_pos. This test is redundant with literally every

* Delete the VTOC-related portion of zpool_create_008_pos. FreeBSD doesn't
use VTOC.
* Replace dumpadm with dumpon and swap with swapon in multiple tests.
* In zpool_create_015_neg, don't require "zpool create -n" to fail. It's
reasonable for that variant to succeed, because it doesn't actually open
the zvol.
* Greatly simplify zpool_create_012_neg. Make it safer, too, but not
interfering with the system's regular swap devices.
* Expect zpool_create_011_neg to fail (PR 241070)

In FreeBSD 11 along with the rework on the collation, mklocale(1) and colldef(1)
has been replaced by localedef(1) (a note has been added to the manpage to state
it).
mklocale(1) and colldef(1) has been kept around to be able to build older
versions of FreeBSD. None of the version requiring those tools are supported
anymore so it is time to remove them from base
When the pwm.9 manual was removed, a symlink between pwmbus.9 and pwm.9 was
created, but there's an entry in ObsoleteFiles.inc to remove pwn.9, meaning
that on every installation pwm.9 is created, and make delete-old deletes it.
Remove the entry from ObsoleteFiles.inc, the symlink is clearly intentional
and shouldn't be removed.

The KPI have been reviewed and cleansed of features that were planned
back 20 years ago and never implemented. The pfil(9) internals have
been made opaque to protocols with only returned types and function
declarations exposed. The KPI is made more strict, but at the same time
more extensible, as kernel uses same command structures that userland
ioctl uses.
In nutshell [KA]PI is about declaring filtering points, declaring
filters and linking and unlinking them together.
New [KA]PI makes it possible to reconfigure pfil(9) configuration:
change order of hooks, rehook filter from one filtering point to a
different one, disconnect a hook on output leaving it on input only,
prepend/append a filter to existing list of filters.
Now it possible for a single packet filter to provide multiple rulesets
that may be linked to different points. Think of per-interface ACLs in
Cisco or Juniper. None of existing packet filters yet support that,
however limited usage is already possible, e.g. default ruleset can
be moved to single interface, as soon as interface would pride their
filtering points.
Another future feature is possiblity to create pfil heads, that provide
not an mbuf pointer but just a memory pointer with length. That would
allow filtering at very early stages of a packet lifecycle, e.g. when
packet has just been received by a NIC and no mbuf was yet allocated.
