I have been using LS for many years now and although generally stable I have noticed and I am sure others have too that comfort updates in the V3 release can quite often be problematic.
Many Times we have had niggly bugs appear after a comfort update that would be really useful to roll back the code changes to the earlier version.

I know that best practice dictates that you really should backup the codebase first, but not everybody does and sometimes even the best of us forget (I just did).

Just an idea.
