Upgrading Flash Media Server

(Since we can't edit our posts, I'll post again...)

I have Flash Media Interactive Server 3.5.0 r405 installed on a Win2003 server.

Looking at the FMS upgrade page...

I am not certain which upgrade(s) I should install.  Some of the version numbers/dates are out of sequence:

-Flash Media Server 3.5.3, December 18, 2009
-Flash Media Server 3.0.5, January 28, 2010

Is it necessary to install upgrades in sequence, or will the latest upgrade include all previous updates?
