Is there a latest and greatest version of the Fisher F75?

If so, what new features does it have and how would I visually distinguish it from previous versions of the F75?

How many versions of the F75 are there? or How many versions of the F75 will there be?

The F75 and F75 LTD with FA and DST has been the same since November 2014. These have user selectable version 9.0 and 9.1 on startup with menu button pressed down and trigger forward when turning on (use knob to select). These are sometimes called Enhanced, LTD2, Gold, or 85th anniversary editions as well. All the same thing built since Nov 2014.

There originally was a regular F75 and then the one with Boost/Cache a few years later. Lots of lingo used but generally called F75 regular and F75 LTD or SE. I have no idea what software versions those have variations of.

The newer ones have the deepest Disc depth. The older ones have deeper AM depth.

I must say personally the newer ones are much more enjoyable to use.
