+======================================================
+Feature: #638 - Move currency translation to a service
+======================================================
+
+See `Issue 638 <https://github.com/extcode/cart/issues/638>`__
+
+Description
+===========
+
+Currency conversion is currently very strongly linked to the cart model and the
+way in which the currency conversion factor is loaded from TypoScript.
+
+In order to be able to obtain the conversion factor from other sources, the
+calculation is carried out by the `CurrencyTranslationService`. This service is
+instantiated via the `CurrencyTranslationServiceInterface` interface so that a
+corresponding exchange via DI is possible.
+
+The implementation should only be a start and does not yet offer a stable API
+because the behaviour must remain the same within the published versions. For
+this reason, the `CurrencyTranslationServiceInterface` is marked as `@internal`.
+Use is at your own risk! Changes to the service interface must be observed
+independently in the event of updates!
+
+Impact
+======
+
+No direct impact.
