693	A big improovement to FileFields	mordaha@…	Adrian Holovaty	"It will be very cool to make a ""historical"" FileField on a meta-level.

So, when a new file uploaded, old file will not deleted, but saved with date/version information about change.

And later, we will have all the history about file changing.

The document storage applications will be much easy to develop.

I be able to make such FileField, but i need a hints how to do this, i think it will reflects on meta system (additioanl ""history"" table required in each field)
