A new test build for PUBG has been released to the game's test servers, and within it users have apparently found info such as a minimap for the upcoming desert map.

The extracted minimap appears to have placeholder names like Murderland, craters, and topography that will surely have an effect on gameplay.

Also found in the data was a work-in-progress jetski, a new area for Erangel, and more.

Our Take 
Since datamining like this is common, I'm sure the developers expected this and it's no accident.
