It's the most recent release and can be downloaded by clicking here. It's still a release candidate (in its final testing stage), but it's stable. Also, as to shutting the guest OS down, exiting the virtual machine is usually sufficient as the virtual machine automatically saves the current state. It never hurts to 'shut down' the guest OS normally, though, to avoid potential errors, such as a file from the guest OS not being written to the final destination properly.
Hope this helps,
I couldn't find a forum area for this one, so I thought here was the best spot! I just downloaded the VMware Player program because of my interest in running a virtual Ubuntu Linux. When I go onto VMware's marketplace tons of Ubuntu Linux downloads pull up (some with the same name)! How can you tell which one is the best and most reliable to download. Also, when you exit the Virtual Machine, do you have to turn the guest operating system off, or will VMware Player do it for you? Please help!!!
