Release 2023-07-17

We added contract migration support! If you already have a running subscription business and want NBX to start billing your subscriptions within their life cycle you can now specify a "Billing Start Date" and NBX will take care of all billing periods after that date.
We introduced a new "Dunning archived" notification you can subscribe to. This will inform you whenever an invoice has surpassed the next dunning level and a pdf has been archived that can be sent to your customer.
Various webportal improvements:
- Improved some response messages in our webportal, like user deletion messages.
- We renamed "amount" to "quantity" where appropriate to clarify which values are about the number of things and not the monetary amount.
- Improved the "create Usage Option" user experience. You now need fewer steps to correctly create such an Option.
