Improvements have been released to Stax's Accounts API endpoints with a focus on account alias management, AWS account ID filtering, and pagination.

• Account Alias management: The Accounts API endpoints (stax-au1 stax-eu1 stax-us1) now support creating and updating account aliases for Stax-managed AWS accounts. This is enabled by way of the AwsAccountAlias request parameter. Account aliases must comply with AWS requirements.
• AWS account ID filtering: The Accounts API endpoints (stax-au1 stax-eu1 stax-us1) now support filtering AWS accounts by their AWS account ID. The previous behaviour required that filtering be performed based on the Stax UUID for accounts. This is enabled by way of the aws_account_id_filter request parameter.
• Pagination improvements: A bug impacting pagination of the Fetch Accounts API endpoint has been fixed. Previously, a GET request to the Fetch Accounts (stax-au1 stax-eu1 stax-us1) endpoint would return some pages of empty results when a filter was applied. With this resolution, empty results are removed from responses and only resources identified by the filter are returned.
