Introducing the InteractionModel interface of the Alexa Voice Service, which enables device makers to support the Alexa Routines feature in their products with Alexa built-in.

Today we’re excited to announce Alerts interface version 1.3, which allows Alexa-enabled products to support several new features, including the deletion of multiple alerts, volume control using the Amazon Alexa App, and the selection of custom alert tones using the Amazon Alexa App.

We're excited to announce the AVS Capabilities API. As Alexa gets smarter with new features and updates that require client-side code changes, you can use the Capabilities API to let Alexa know which interfaces and interface versions your product supports following an over-the-air update.
