- Fixed that the status button counters on the stock overview page ("X products are overdue" and so on) included products which have the option `Never show on stock overview` enabled
- Fixed that adding Userfields to existing stock entries was not possible (only editing existing Userfield values, e.g. added during purchase or inventory, was possible)
- Fixed that it was not possible to change a products stock QU, when the needed unit conversion (old QU => new QU) was only defined globally (means on QU level) or by the products "Factor purchase to stock quantity unit"
- Fixed that when changing a products stock QU, the products "Quick consume mount", "Energy (kcal)" and "Tare weight" wasn't updated according to the corresponding unit conversion factor
