+
+
+### Features
+
+* **client-iotsitewise:** AWS IoT SiteWise now supports versioning for asset models. It enables users to retrieve active version of their asset model and perform asset model writes with optimistic lock. ([ebc9981](https://github.com/aws/aws-sdk-js-v3/commit/ebc9981fc23253adbd350039f8e0d5012fa73732))
+* **client-workspaces:** This release adds support for creating and managing directories that use AWS IAM Identity Center as user identity source. Such directories can be used to create non-Active Directory domain joined WorkSpaces Personal.Updated RegisterWorkspaceDirectory and DescribeWorkspaceDirectories APIs. ([206a25b](https://github.com/aws/aws-sdk-js-v3/commit/206a25b7f8d801a1bd7b81ae237f76d9e6a0ba5b))
