Blender version in file properties

As someone who uses multiple Blender versions simultaneously, I often ask myself what version I made a Blender file in. The same is for updating blender files to newer versions, it would be humongeous to be able to easily check the blender version a Blender file last was saved from.

I suggest storing this in the file's properties, just like Creation date , Last changed date , (or in the case of music) Compositor , Publisher , etc. If possible, a new propertie called something along the lines of Blender version would be added, but if that's not possible, a non-used propertie can be used instead.
