Should we upgrade AsyncOS?

[blroberts2]

We are running a C380 with AsyncOS 8.5.7-042 and everything works and runs wonderfully.  Since spam definitions aren't tied directly to the AsyncOS, is there really a need to update to 9.6.0-042?  Is it one of those 'if it aint broke, don't fix it' type upgrades?
