Rewording Steev's comment, this wording comes across as rather more
informal than most news items. I rather like the approach myself but it
does rather stick out.
A more formal approach might be:
Two points:
1) CONFIG_FHANDLE=y is required in your kernel config for >=udev-209.
2) ...
> /lib/udev/rules.d/80-net-name-slot.rules was renamed to
> 80-net-setup-link.rules and the actual configuration is at

That's a run-on sentence. Again, not acceptable in formal writing.
Continuing from the above, here's a suggested point 2:
2) The former /lib/udev/rules.d/80-net-name-slot.rules file is renamed to
80-net-setup-link.rules in the same location. If you were overriding
udev's predictable naming feature using an identically named file in
/etc/udev/rules.d, either rename it accordingly or see the wiki link[1]
below for other options.
Meanwhile, on the wiki I'd suggest stressing the kernel commandline
option (mentioned further up the wiki page but not in the 208-to-209
section), since presumably it's not going to be constantly changing to
suit systemd-udev's upstream whims, as the script name disabling method
seems to be doing.
Optionally (and IMO preferred), make that the suggested solution in the
news item with the following suggested text replacing the above:
2) /lib/udev/rules.d/80-net-name-slot.rules is being renamed. If you
were overriding it with an identically named file in /etc/udev/rules.d/,
you'll need to change your override as well. We suggest using the
net.ifnames=0 kernel commandline option method as that should remain
stable through many udev releases. For other options and more detail,
see the wiki link[1] below.
