I'm going to assume you meant version 4.1(2).

Anyway, is there a list of the syslog message types that have been added since 4.0?  I don't see any mention of it in the 4.1(2) release notes.

The latest version of MARS only support up to FWSM version 3.2.5 as per the following compatibility table:

http://www.cisco.com/en/US/docs/security/security_management/cs-mars/6.0/compatibility/local_controller/dtlc60x.html#wp75149

However, you can add the FWSM as 3.2 version, and it will be backward compatible. Only new syslog messages on FWSM version 4.2 will not be understood by the MARS.

I don't know if anyone else sees this issue, but if the device is  part of any automated (re)discovery, it will get reset to version 3.1.   2-3 times in the last couple of weeks, I've manually set my FWSMs to  version 3.2, only to have it as 3.1 a few days later.

In the end, it doesn't really matter.  But it is supremely frustrating.
