Multiple versions of autosave files Very recently, blender crashed and deleted some of my work.  I looked into the autosave directory after I tried to reopen my file.  The reopened older version (without my recent changes) was the only version available in the autosave directory.  It disappointed me that my changes were gone in the very recently autosaved file.  In the user preferences panel I saw some autosave settings, none of which seemed to change how many previous versions of autosave files there were.

My question is this:
Is there a setting in the user preferences that will alter the amount of autosave versions saved as seperate files?  Is there an addon that will work to the same effect?

Cheers
There is an addon now. You can find it here.

The Save on open option lets you go back to the start, while Save before close covers you for forgetting to save when opening another file or starting a new one, it doesn't get triggered before closing blender so that can still get you. While they do sound good, they can be a bit much if you just go quickly looking through a lot of blend files.

File copies are saved with a timestamp prefix in the name, so you can easily see how old any copy is or choose how far back you want to go.
