The thing is I don't have enough hardware (I only have one test box) that I can spare to update from my 7.5.1 I use for other things, and am not sure whether I want to go down that path just yet. I have a client with a Win7 box that could do with putting into his domain, and I have just found the SME Version 7.x patch that will let me join the Win7 box to the Domain (from Sernet). That will probably squeeze some more time out of my client's production servers as some are running Zarafa and this has some patches at this stage which make me nervous to upgrade just yet. And at this stage, running yum list updates won't show the version 8 ones.
