ACS 5.4 vs 5.5

Curious to know the differences and hassles to upgrading from ACS 5.4 to 5.5. I know that there is a patch that you have to run before the upgrade itself. But is it really worth the upgrade? Just because a "new" version has come out, does not necessarily mean that you really need to run out and upgrade. I'd like to hear from those that have done the 5.4 to 5.5 upgrade, and see what issues or pitfalls were encountered.

I have become the TACACS administrator for my new employer, and we are in this situation. If I understand the 5.x series, we upgrade the primary, and it should push out to the secondaries automatically.
