You can now set a dead-letter queue (DLQ) to an Amazon Simple Notification Service (SNS) subscription to capture undeliverable messages. Amazon SNS DLQs make your application more resilient and durable by storing messages in case your subscription endpoint becomes unreachable.

Amazon Redshift now supports cross-instance restore to allow you to restore Redshift snapshots to clusters that are different sizes or running different node types. This simplifies snapshot restore workflows to support your evolving use cases. You can change instance type and count based on compute resources, storage capacity and cost requirements of your specific workloads. For example, you can cross-instance restore a snapshot of your production dense-compute cluster with small instances into a cluster with powerful large instances to serve more demanding workloads, or to a lower-cost development cluster. Once a cluster is restored, you can resize it as your performance and capacity needs change over time.

You can now use Amazon WorkSpaces APIs to register your directories with WorkSpaces and to modify directory details. The new APIs enable you to automate your workflows that require registering a directory with WorkSpaces or modifying directory level WorkSpaces properties including default WorkSpace creation settings, self-service permissions, and access controls.

AWS Elemental MediaConvert now offers support for Dolby Vision high dynamic range (HDR) video encoding for better color, contrast, and brightness on consumer display devices and support for Dolby Atmos audio encoding for immersive surround sound. MediaConvert used in combination with these technologies from Dolby Laboratories give video providers the ability to create premium experiences for consumers.

AWS Managed Services (AMS) launched support for SUSE Linux Enterprise Server 12 SP4. You can now run business critical applications on SUSE Linux Enterprise Server in your AMS Managed landing zones. SUSE Linux Enterprise Server support has expanded the addressable inventory of customer applications that can be migrated to AMS for ongoing operations with minimal refactoring.

You can now use Amazon WorkSpaces in the AWS China (Ningxia) Region, operated by NWCD. WorkSpaces is a fully managed, secure Desktop-as-a-Service (DaaS) solution which runs on AWS. With WorkSpaces, you can provision virtual, cloud-based desktops for your users, providing them access to the documents, applications, and resources they need, anywhere, anytime, from any supported device. You can pay either monthly or hourly, just for the WorkSpaces you launch, which helps you save money when compared to traditional desktops and on-premises VDI solutions. 

Customers can now deploy to ECS from within a GitHub repository through the new ECS starter workflow on GitHub Actions. Whenever new code is pushed into a repository, the workflow builds and deploys it to AWS using 4 new GitHub Actions from the GitHub Marketplace. This speeds up the deployment process by automating each step and allows developers to push and test code in the cloud more efficiently.

Amazon Simple Email Service (Amazon SES) now offers Federal Information Processing Standard 140-2 (FIPS) compliant endpoints. FIPS 140-2 is a U.S. and Canadian government standard that specifies the security requirements for cryptographic modules that protect sensitive information.

You can now use Systems Manager Automation to build and share standardized operational playbooks to ensure consistency across users, accounts, and AWS Regions. With the ability to now execute scripts and add wiki-style documentation, you can reduce errors and eliminate manual steps such as navigating written procedures in wikis and running terminal commands. 

You can now assign tags to Amazon Connect users to better organize or manage access to them via API. Tags are key value pairs which enable you to control access to Amazon Connect users who are tagged by team, role, or other criteria. For example, you can grant API access to all agents, to only agents tagged to a given line of business (LOB), or if you use third-party outsources, to only agents tagged as their employees.
