I remember the K-5II/K-5IIs which was about as minor an upgrade as one might imagine (AF upgrade* mostly with the "s" losing its AA filter). The K-1II appears to be similar in scope and impact.

* The step from SAFOX IX+ to SAFOX X provided additional low light sensitivity as well as fixes for poor performance under tungsten light and overall improvements that were incremental, but needed.
