What version do you preinstall with a new hosting package?

We always preinstall the latest stable eZ Publish version. Alpha, Beta and Release Candidates (RC) are not considered to be stable.

Example:
If newest releases are 4.0.1-RC1 and 4.1-alpha, we will install version 4.0. Once a couple days later 4.0.1 is released we will install that current latest stable. Once 4.1 gets released we use that one.
