Changes Amazon SNS introduces the PublishBatch API, which enables customers to publish up to 10 messages per API request. The new API is valid for Standard and FIFO topics.
Changes This release adds SMS sandbox in Amazon SNS and the ability to view all configured origination numbers. The SMS sandbox provides a safe environment for sending SMS messages, without risking your reputation as an SMS sender.
Changes SNS now supports a new class of topics: FIFO (First-In-First-Out). FIFO topics provide strictly-ordered, deduplicated, filterable, encryptable, many-to-many messaging at scale.
Changes With this release AWS SNS adds tagging support for Topics.
Changes Added an optional request parameter, named Attributes, to the Amazon SNS CreateTopic API action. For more information, see the Amazon SNS API Reference (https://docs.aws.amazon.com/sns/latest/api/API_CreateTopic.html).
Changes The SNS Subscribe API has been updated with two new optional parameters: Attributes and ReturnSubscriptionArn. Attributes is a map of subscription attributes which can be one or more of: FilterPolicy, DeliveryPolicy, and RawMessageDelivery. ReturnSubscriptionArn is a boolean parameter that overrides the default behavior of returning "pending confirmation" for subscriptions that require confirmation instead of returning the subscription ARN.
