1and1 package revamp - for existing customers also?

Has any existing 1and1 customers seen the new levels on their packages? Do the new offerings apply to existing customers also?

You can then select the same
level of service you currently have, but it will update
your contract so that you have the current specifications.

I wonder if it also renews/prolongs the contract…

here is the answer, direct from 1and1 support:

If you would like to update your Web Hosting packages
so they include the most current feature set, you can
do so via the 1&1 Control Panel. Once logged into the
Control Panel, navigate to the Administration tab,
scroll down to the Order More Features section and
select “Switch Package”. You can then select the same
level of service you currently have, but it will update
your contract so that you have the current specifications.

How did you notice that? Have they announced that somehow?
If you find out that occasionally that appears a very strange behavior from them then.
