+## 2024-06-14 Remove all uses of `github.com/pkg/errors`
+
+### Reasoning
+
+[github.com/pkg/errors](https://github.com/pkg/errors)` is deprecated. Since the built-in `errors` package improved a bit in the recent Go versions, we should remove all uses of `github.com/pkg/errors` and replace it with the `errors` package.
+
+### Hints
+
+* Use the pattern `return fmt.Errorf("something happenend with %#v: %w", someID, err)`
+* The stack trace feature gets lost. Therefore it is suggested to properly add error messages each time handling errors.
