This seems a bit “unfair.”
1.03 fixed some instability. Users did not report USB issues in 1.03, and many returned to 1.03 for its USB capabilities when they ran into issues in later firmware.
1.04 updated a ton of blocks to match the Axe3 and new amp models among many other features and fixes. Many users said USB communication was improved, while a small amount said they started having USB connection issues, where some of that seemed to be hardware/unit specific in the 1.04 thread. Few USB audio issues were mentioned.
1.05 fixed a lot of bugs and to my knowledge is where the USB audio issues began.
Majority of users had no issues in 1.03 and 1.04, so to mention those seems a bit out of place in this context.
