I have had 1.03 installed for so long that I couldn’t even tell you when that “update” was released. Perhaps pursuing the weekly development updates from the past would reveal when the last Marketplace 247D update was released.
Either way, I’m not sure how to help answer the question as to why it is a different version than the developer-direct version you have.
Unfortunately, there are no version notes in the Content Manager More Info box.
EDIT:
Here is the Dev Update when the 247D was released for the Marketplace:
Otmar’s last post in this thread was this:
Seeing as that was his last post, I don’t remember if we ever did get an update to the aircraft after its initial release on the Marketplace. I think he simply vaporized from that point and we’ve all been missing him since.
The version discrepancy could be that the Marketplace ingestion staff kicked it back to him a couple of times for errors that would have prevented them from accepting it. Of course, that’s just me guessing.
