It appears the latest firmware if you go by date code is ISTA/P;2.48.0;E89X-12-11-507? I also see one referred to as 2.48.2 but the date code is E89X-12-07-508. I'm a bit confused because the 2nd one has an earlier date code but the last three numbers and the "2.48.2" seem to indicate it is a newer firmware?
Different integration levels can have the same date code

Take a look at the 231E update thread, I think I posted the integration levels there awhile back. Once I get back in town I can give you a more definitive answer
