I think most of the improvements are around the granularity of control that Amazon's, and PayPals soon to be provides.

I havent developed solutions on Amazons payment platform yet but from the looks of the payment API and what they refer to as their 'GateKeeper Language' you just define a payment type of re-ocurring and process the payments. Each payment will return an ID that you would store in a colum in your order table. A job that runs periodically could just poll the service using the GetTransaction call to get any status of potential failure.

How has the re-occuring payments system improved?

I've always shied away from it in the past since it's been difficult to get information back from the API that indicated whether the payments had been cancelled.
