Please don't update the release notes like this. The upgrade has been
designed to work correctly by simply running 'apt-get update' and
'apt-get dist-upgrade' until these and all other packages on the
system have been updated. This has been tested countless times.
Unfortunately Paul had a different experience on his NAS box when
upgrading it, but that case is not the usual case and should not be
the motivation to make new general recommendations.
