I'm new to OO. As I learn software, little things grab my attention, so I'm wondering if previous OO versions used filenames such as .oo1 or .oo2? I noticed OO4 is using .oo3. Was .oo3 made for OO3? Are the filenames expected to change to .oo4 in the near future?

This is not a feature request by any means. I'm merely curious.
