DiagBox 7.01 is not equal to DiagBox 8.01, if you look inside both of them you will find that they are similar but not equal. For example DiagBox v7.xx uses Java v6 and DiagBox v8.xx uses Java v7.
All DiagBox updates v7.67 in sequence up to v7.76 and DiagBox updates v8.03 up to 8.12, are equal and have the same sequence.
The Appli.com version 4.3.4 is included in both DiagBox update v8.02 (98.56MB), which is not equal to DiagBox v7.66 (81.54MB) but it also has Appli.com 4.3.4.

Download both files from the links, look into "\AWRoot\dtrd\firmware\appli.com" You will find that the files exists in both and it is version 4.3.4.
Now I used from 4.2.0 to 4.3.4 and I don't notice any difference. I have only one Full Chip Revision C device and my car is an oldish Citroen C8 HDi. I don't know if this is because I have a good XS Evolution device or and easy going car???
