Recent version of DW Embraer 170 is what?

Hello everyone,I'm searching for the Embraer 170 base files made by Dreamwings, but really confused about the version information. From what I can see is that there are three versions v.2, v.3, and v.3.5 (v.3.5 is just an update file.). What is the latest version? Are there major differences besides texture incompatibility?I have the JAir v.2 texture and want to use it for v.3 because there is an FSX compatible panel on v.3 not on v.2.
