Oracle Linux as a replacement for RHEL\CentOS

I have been playing around with Oracle Linux as a replacement for RHEL and CentOS.

Unlike RHEL, updates are available without a support contract.
Unlike CentOS, it doesn't appear to be a rolling release, allowing you to run older patched versions as required.

How to limit the number of installed Kernels:

Anyone know of a way to stop the version upgrading from 7.0 to 7,1 for example?
