breaking changes when migrating to the new frontend:

I am trying to ensure a certain level of backwards compatibility however there are a few changes you need to be aware when migrating to the new frontend.

general

• default date format is changed to %Y-%m-%d

DKBRobo.account_dic()

• account ordering is based on the new frontend
• debit cards are shown in overview
• IBANs are now represented without spaces
• card numbers are masked
• product groups (taken from UI) are shown in account overview
• additional account attributes (currency code, limit)
• additional card attributes (holder-name, status, expiry date)

DKBRobo.get_standing_orders()

• account_dic[x]['id'] must be specified as input
• data-structure changed (interval subtree added)

DKBRobo.get_transactions()

• "mandatreferenz" and "customerreferenz" attributes will only be shown if available

DKBRobo.scan_postbox()

• the document list provided in via API larger than shown in UI
• so far only documents from categories "Kontoauszüge" and "Kreditabrechnungen" provided via API

The old frontend will be supported as long it is available. The plan is to use the legacy_login parameter switch between old and new frontend. I will also try to keep method names inside the DKBRobo() class the same. There might be some smaller changes (f.iiorder of accounts and cards in dkb.account_dic) but overall look and feel should stay more or less similar.
