  • Improved accuracy of CloudTrail event documentation for AWS Organizations membership operations.

AWS Single Sign-On Admin

Amazon Aurora DSQL

• Features

  • UpdateCluster now checks the RemovePeerCluster permission on the specific cluster being removed, not a wildcard and docs now clarify how to set kmsEncryptionKey so the cluster uses the AWS-owned key.

Amazon Connect Service

• Features

  • Adds SearchVectors and vector index support to the DynamoDB low-level client (sync and async) and Enhanced Client, including vector index table operations, table.vectorIndex() search handles, and enhanced search request/response types.
  • Adds annotation-driven vector index support to the DynamoDB Enhanced Client via @DynamoDbVectorAttribute, @DynamoDbSearchVectorsHashKey, and @DynamoDbSearchVectorsInlineFilterKey on bean and immutable schemas, enabling no-arg createTable() and vector search through annotation-derived table.vectorIndex() handles.

Amazon Elastic Compute Cloud

• Features

  • Amazon EC2 now supports Application Status Checks, a new status check that monitors your application's health through configurable HTTP(S) paths and ports, so you can detect and automatically respond to application-level impairments.

• Features

  • Added ClientExperiencePolicy to ClientProperties object for ModifyClientProperties and DescribeClientProperties APIs.

Inspector2

• Features

  • Adding Azure SBOM export capability.
