As we had a long term planned maintenance window and we had issues with diveres builds before 5.2.9 and would have had issues regardind services on secondary interfaces. We decided on some installations to take the risk of a very new firmware on go directly to 5.2.10. On smaller installations like 60D and on clusters up to 800C - every major feature being used.
So far so good - we have not seen any issue so far. Only Fortimanager integration with FMG 5.2.9 gives us some minor troubles.
