Congratulations on the stable/13 release!

[Andrew Reilly]

In case anyone's interested: for this morning's software maintenance 
session (at home) I upgraded my file server from FreeBSD stable/12
to the recently released stable/13.  From source, in-place, on a
running, on-line system.  Despite the fact that the entire ZFS
subsystem has been replaced, which is what caused me to wait for a
couple of weeks, the upgrade appears to have been flawless.  Not a
single error message on boot-up.  Not a single failed service.
Everything is working perfectly.  Zpool status told me that I should
upgrade the pools, and did: that turned on a dozen or so new features
that I'm sure are useful.  Total downtime about a minute or so:
just the time it took to reboot.  I'm amazed.  Good on the FreeBSD
developers and (especially) the release engineers!

cd /usr/src
git switch stable/13
make -s -j20 buildworld kernel
mergemaster -p
make -s installworld
mergemaster -U
shutdown -r now

zpool status
zpool upgrade backup20
zpool upgrade root
zpool upgrade tank

Done!

Cheers,

Andrew
