To ensure support for 3ds while also maintaining the ability to process offline transactions (e.g. on schedule payments without the customer's interaction), we are making use of the "off_session" flag.

The application <> account relationship has now changed so a single application can be used any number of times to generate new accounts. This means a merchant only needs to sign up once even if their application will result in the creation of 5 accounts, for example. There will also be changes to the user experience to provide visibility on which accounts have been created from a single application.
