The April 2026 release includes the following important notice:
Preview initiated for auto-tuning
Effective in the April 2026 release, auto-tuning is available for preview.
Auto-tuning dynamically adjusts key parameters for database ingestion and replication initial load jobs and the unload phase of combined load jobs to optimize performance and resource use. Auto-tuning is based on performance and system metrics automatically collected from your environment and on application-specific metrics such as JVM heap allocation and task capacity. To enable auto-tuning for a task, select the Auto-Tune option on the last page of the task configuration wizard. The following source types are supported with any target type: Db2 for i, Db2 for LUW, Db2 for z/OS, MySQL, Oracle, PostgreSQL, SAP HANA, SQL Server, and Teradata.
Preview functionality is supported for evaluation purposes but is unwarranted and is not supported in production environments or any environment that you plan to push to production. Informatica intends to include the preview functionality in an upcoming release for production use, but might choose not to in accordance with changing market or technical circumstances. Note that if you are working on a preview POD, all data is excluded from SOC 2 compliance coverage. For more information, contact Informatica Global Customer Support.
Dropped support for the older task configuration wizard
Effective in the April 2026 release, Data Ingestion and Replication drops support for the older task configuration wizard for application ingestion and replication tasks and database ingestion and replication tasks. The newer task configuration wizard, which was first introduced in October 2024, is now the only supported configuration wizard for these task types. The newer wizard will be automatically enabled for any users who haven't previously migrated to it.
Dropped support for Google Analytics Mass Ingestion Connector
Effective in the April 2026 release, Informatica drops support for the Google Analytics Mass Ingestion Connector following Google Analytics' deprecation of the UA4 interface. While the connector might still appear in Application Ingestion and Replication tasks, it no longer functions. Informatica will remove the connector and its documentation in a future release.
Dropped support for email and password authentication in Zendesk Mass Ingestion Connector
Effective in the April 2026 release, Informatica drops support for email and password authentication to Zendesk following Zendesk's deprecation of email and password access for API calls.
Deprecated support for session-based authentication in Data Ingestion and Replication
Effective in the October 2025 release, session-based authentication is deprecated. Informatica intends to drop support for session-based authentication in the October 2026 release.
Deprecated functionality is supported, but Informatica intends to drop support in a future release. Informatica requests that you transition to different functionality before the functionality is dropped.
Informatica plans to replace session IDs used for user authentication with JSON Web Tokens (JWT). The organization administrator can change the authentication type used for REST API requests on the Settings page in Administrator. If the administrator enables the JSON Web Token (JWT) authentication type, browser-based user interface communications seamlessly use JWT behind the scenes.
For REST API calls, session IDs must still be included in request headers. However, with JWT authentication, the session value carries a JWT with a fixed expiry time configured in Administrator. As a result, REST API scripts must be updated to handle automatic re-authentication before or after the token expires. For more information, see the JWT Support Knowledge article.
Session-based authentication is the default authentication type. Sometime after the July 2026 release, JWT will be the default authentication method. By October 2026, session-based authentication will no longer be available.
