What IOS file to use for upgrading WAAS?

Question

I've got several 7341s, 522s, and 612s all running 4.17 (waas-4.1.7.11-K9.bin).  I'd like to upgrade to the new 4.2.3, but there are now four different codes; ie. waas-accelerator-4.2.3.7-K9, waas-accerlator-4.2.3.7-npe-K9, waas-universal-4.2.3.7-K9, waas-universal-4.2.3.7-npe-K9. Which ones do I use? Is there a matrix somewhere that describes the different code types?
