### Stock

- Fixed that certain fields were not copied when copying a product

### Calendar

- Fixed that the iCal export was broken (any shared `https://<Grocy>/api/calendar/ical?secret=xxx`-link always returned `401 Unauthorized`)

### General

- Optimized that table dropdown filters now search accent insensitive
- Fixed that it wasn't possible to log in using passwords containing non-latin characters

### API

- New API endpoint `/stock/products/{productId}/copy` (to copy a product)
- Fixed that API key authentication did not work when running Grocy in a subdirectory
