This means 10 = 2010
12 = December
1001 = version within December.
It is important that you stay up to date as you will benefit from all the latest enhancements made in 4LODGE
Your 4LODGE system can be upgraded from ANY version to the latest, however - please ensure you have a backup in case something bad goes wrong!
