Summary

This does not include entries for changes that were included in 12.2
release.

123

not yet enforced, perhaps

151

As discussed on IRC perhaps a more sweeping comment on a.out retirement

161

we might want to mention "obsolete" here instead of (or along with) unsupported

267

Maybe also "obsolete"

e1000 is old, ed is obsolete

419

Maybe "as a compiled-in default" or such, or "SCTP support has been modularized and is no longer compiled into GENERIC by default"? As is sounds more like it is being removed.

442

Maybe some reference to the hardware that was supported by armv5 and when it was removed?
@imp?

We probably won't toggle the default in 13.0's lifetime though, so I'm not sure "yet" makes sense in that context. When we do toggle the default in a future release that will probably be its own item.

151

Agreed, but I think that should probably be a followup. For this commit I've tried to limit to describing the relevant entries from RELNOTES without expanding things too much farther than that. I have expanded a few though such as including the OpenSSL commit hash in the KTLS one.

419

I've done a variant of the latter:

SCTP support is now available as a new [.filename]#sctp.ko# kernel module
and is no longer compiled into GENERIC by default.
gitref:e64080e79c53[repository=src] {{< sponsored "The FreeBSD Foundation" >}}

442

I'm happy to defer to @imp on fleshing this out further in a followup. The comment in RELNOTES is:

r356263:
	armv5 support has been removed from FreeBSD.

Overall LGTM, I am happy to propose a followup for things I suggested/pondered.

Yes, maybe "currently not enforced by default" - i.e., I would like to indicate this is not necessarily our desired end state. I can propose a followup change.
