Been out for a few months now, they have v5 and v6 on the drawing board. They are constantly tweaking things to improve it, I don't know how many different versions the MM had but easily a dozen...

do you know the differences between the V3 and 4?

I believe they changed a few little components, unless you are looking very closely at the 2 of them I doubt you'd be able to tell them apart.

We continually make small changes to our products. These usually have nothing to do with performance and more to do with parts availability. Since V3 we will not be announcing version numbers because it creates confusion for no reason. If we change a part number but don't change the value of the part it changes the version for manufacturing but makes absolutly no difference in how it works.
