 - The endpoint `/stock/products/{productId}/locations` now also returns the current stock amount of the product in that loctation (new field/property `amount`) (thanks @Forceu)
 
-### General & other improvements
+### General & other improvements/fixes
+- Fixed that all number inputs are always prefilled in the browser locale number format
 - New `config.php` setting `FEATURE_FLAG_STOCK_BEST_BEFORE_DATE_FIELD_NUMBER_PAD` which activates the number pad for best-before-date fields on (supported) mobile browsers (useful because of [shorthands](https://github.com/grocy/grocy#input-shorthands-for-date-fields)) (defaults to `true`) (thanks @Mik-)
 - Enhancements for the camera barcode scanner (thanks @Mik-)
   - The light button only displayed when the device has a flash light
