Just received this notice…
In July 2014, we released In-App Purchasing (IAP) v2.0, which represents an evolution of the API with several major updates that require changes to v1.0 integrations. Now that a significant time period to migrate from v1.0 to v2.0 has passed, we are planning to deprecate v1.0 on April 30, 2016. At this time all active apps will continue to function as expected, but we will begin to fail new submissions and updates still integrated with IAP v1.0. Highlights on the features of v2.0 and migration details are noted below.
Is there a timeline for v2 compatibility?
Thanks.
[UPDATE]
Amazon IAP v2 plugin released on April 6th.
