+
+== Overview
+
+Goal is to integrate MicroProfile (MP) Fault Tolerance (FT) 4.1 specification from the MP Platform 7.0 to WildFly at default stability level.
+To certify functionality, the MP FT TCK is run as part of the WildFly testsuite.
+
+=== User Stories
+
+User wants to deploy an application using MicroProfile Fault Tolerance 4.1 from MicroProfile Platform 7.0.

+=== Related Issues
+
+* https://issues.redhat.com/browse/WFLY-19592[WFLY-19588 Implement MicroProfile Platform 7] – MP Platform parent issue
+* https://issues.redhat.com/browse/WFLY-19590[WFLY-19590 MicroProfile Telemetry 2.0] – dependency of this issue for full Telemetry metrics integration
+
+// EAP Tracking issue:
+// * https://issues.redhat.com/browse/EAP7-2225[EAP7-2225 [MP Platform 7] MicroProfile Fault Tolerance 4.1]
+
+=== Affected Projects or Components
+
+* Eclipse MicroProfile Fault Tolerance
+* SmallRye Fault Tolerance
+
+=== Other Interested Projects
+
+* N/A
+
+=== Relevant Installation Types
+
+* Traditional standalone server (unzipped or provisioned by Galleon)
+* OpenShift Source-to-Image (S2I)
+* Bootable jar
+
+== Requirements
+
+* Upgrade MP FT specification modules to 4.1.
+* Upgrade SmallRye FT to 6.5.x.
+* Enable integration with MP Telemetry Metrics when the subsystem is available in the serve configuration.
+
+=== Changed requirements
+
+* N/A
+
+=== Non-Requirements
+
+* N/A
+
+=== Future Work
+
+None.
+
+== Backwards Compatibility
+
+The specification and the implementation do not introduce any incompatibilities from the previous version (MP FT 4.0).
+
+=== Default Configuration
+
+There are no changes to the existing configuration.
+
+=== Importing Existing Configuration
+
+The subsystem does not have any configuration, so existing subsystem configuration is not effected.
+
+=== Deployments
+
+The specification and the implementation do not introduce any incompatibilities from the previous version relevant to deployments.
+
+=== Interoperability
+
+* N/A
+
+== Implementation Plan
+
+For the integration with Telemetry metrics to function,
+the integration of its https://issues.redhat.com/browse/WFLY-19590[subsystem and modules] is required.
+Implementation will be done in the created `mp-7-wip` https://github.com/wildfly/wildfly/tree/mp-7-wip[branch] in WildFly upstream repository.
+
+== Admin Clients
+
+* No effect on the existing clients, there are no model changes.
+
+== Security Considerations
+
+* No security implications of this integration.
+
+[[test_plan]]
+== Test Plan
+
+MicroProfile Fault Tolerance TCK tests will be added and executed by CI as part of the WildFly testsuite (in `testsuite/integration/microprofile-tck/fault-tolerance` module)
+WildFly-specific behavior and configuration is covered by existing tests in the WildFly testsuite (in `testsuite/integration/microprofile` module)
+
+== Community Documentation
+
+References to the MP FT specifications in the existing documentation will be updated to reflect the updated versions.
+
+== Release Note Content
