# Release notes for the Blue Prism connector

> Version history for the ABBYY Vantage Connector for Blue Prism: new features, changes, and known issues in each release.

This page lists the new features and known issues in each release of the ABBYY Vantage Connector for Blue Prism, starting with the most recent version.

<Update label="2.1" description="2024">
  The connector is now compatible with Blue Prism 7.2 and supports a server-to-server authentication scheme. If you have an older version of the connector, [update it to the latest version](/vantage/connectors/blue-prism/install#update-the-connector).

  ## Main features

  ### Compatibility with Blue Prism 7.2

  Starting with this version, the connector is compatible with Blue Prism 7.2. To use Blue Prism 7.2, update the connector to the latest version and reconfigure your existing processes to use the **SaveTransactionResult** action. The **GetTransactionResult** action works with Blue Prism versions up to 7.2. For more information, see [Replace the GetTransactionResult action with SaveTransactionResult](/vantage/connectors/blue-prism/install#replace-the-gettransactionresult-action-with-savetransactionresult).

  ### Server-to-server authentication scheme

  The ABBYY Vantage API now supports the Client Credentials Flow, a server-to-server authentication scheme. It is designed for applications that let end users process documents with ABBYY Vantage without having ABBYY Vantage accounts.

  You can enable this flow for any tenant's API client. When you enable it, the tenant administrator assigns the roles granted to the application, and the application receives an access token with those roles. This flow is recommended when an External Identity Provider is enabled for the tenant.

  For more information, see [Client Credentials Flow](/vantage/developer/authentication/client-credentials) and [Creating, configuring, and deleting a Public API client](/vantage/documentation/tenant-admin/tenant-management/configure-client).
