Today Fujifilm release a bunch of firmware updates, including for the X-M5. They all do the same thing: remove support for the older Fujifilm remote and remove mention for the old Instax Share printer.
I was hoping a kaizen update with film recipes.
Here is the new feature guide (PDF) for the X-M5.
