+| January 17, 2020 | Server\-side encryption \(SSE\) for Amazon SNS is available in the China Regions\. For more information about server\-side encryption and how to get started using it, see [Encryption at Rest](sns-server-side-encryption.md)\. | 
 | November 14, 2019 | A dead\-letter queue is an Amazon SQS queue that an Amazon SNS subscription can target for messages that can't be delivered to subscribers successfully\. Messages that can't be delivered due to client errors or server errors are held in the dead\-letter queue for further analysis or reprocessing\.   The Amazon SNS subscription and Amazon SQS queue must be under the same AWS account and Region\. Currently, you can't use an Amazon SQS FIFO queue as a dead\-letter queue for an Amazon SNS subscription\. To use an encrypted Amazon SQS queue as a dead\-letter queue, you must use a custom CMK with a key policy that grants the Amazon SNS service principal access to AWS KMS API actions\. For more information, see [Encryption at Rest](sns-server-side-encryption.md) in this guide and [Protecting Amazon SQS Data Using Server\-Side Encryption \(SSE\) and AWS KMS](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-server-side-encryption.html) in the *Amazon Simple Queue Service Developer Guide*\.  For more information, see the following: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/sns/latest/dg/sns-release-notes.html) | 
 | October 18, 2019 | You can specify a custom APNs header value\. For more information, see [Sending Messages to APNs as Alert or Background Notifications](sns-send-custom-platform-specific-payloads-mobile-devices.md#mobile-push-send-message-apns-background-notification)\. | 
 | September 10, 2019 | Amazon SNS supports the apns\-push\-type header field for mobile notifications sent through APNs\.
