Will the Splunk for FireEye app run on Splunk 5.0?

The documentation states the app is for 4.3.x, but is that the minimum version or the ONLY version supported?

I ask because I've got it installed on a 5.0.3 search head and FE is sending XML logs via HTTP, but I think the transforms aren't working properly. Fields aren't being delimited appropriately and some fields contain data from one or more fields.

Please advise, thanks!
