difference between 7.3.2 and 7.3.3

WE are in the process of deciding on upgrading to oracle 7.3.3 from 7.3.2 at a UNIX (Sequent) machine.

What are the advantages of doing so in terms of the RDBMS performance and/or maintenance ? Any documentation leading to the comments would be very nice and appreciated.

Thanks
Vikas
