Hi,
as far as I can see there is no severe risk: If there is a problem with a beta version, you can leave beta program and switch back to release version (please correct me, if am wrong) .
And the idea of beta versions is - of course - get some test depth bevore rolling out a change to all users. So from my point of view using (= testing) beta versions also improves Kurviger quality - a small contribution everyone can give.
