While investigating 3.x->4.x compatibility for
SERVER-526
I tried to use an executable external fact, but this did not work in 4.0.0 (it worked in 3.7.5). The file is no longer executable on the agent side, so the agent run spits out a warning saying the fact file was parsed but returned an empty data set.
When looking at the HTTP traffic for my executable external fact file, I see the file_metadata response does in fact specify a different mode between 3.7.5 and 4.0.0.
Below you'll find the request+response for the external fact - notice the mode is different in the responses.

I came across some tickets that may be related:
I verified this behavior in our newly-released 4.0.0 packages (PC1).
