This is (generally) true, but we messed up and failed to announce it there
at the time.
Andreas is correct that although we published Kea 1.8.0 last week and updated
the web site to link to the new version we missed the last stage in the
process and failed to announce it properly.
Thanks, Andreas, for pointing out our oversight.
