 - It's now possible to accumulate min. stock amounts on parent product level (new option per product, means the sub product will never be "missing" then, only the parent product)
 - When adding a product to the shopping list from the new context/more menu from the stock overview page and if the product is already on the shopping list, the amount of that entry will be updated acccordingly instead of adding a new (double) shopping list item
 - On the purchase page there is now an option to select that the price is the total price (for the whole amount) - below the price field, defaults to "Unit price" (as it was until now), when set to "Total price", the entered price will be divided by the amount before posting
+- "Average shelf life" on the product card now displays just "Unlimited" when the resulting value would be > 200 years (for products which never expire, as they have a best before date of 2999-12-31)
 
 ### Recipe improvements/fixes
 - Fixed a problem regarding quantity unit conversion handling for recipe ingredients of products with no unit relations, but only a different purchase/stock quantity unit
