+### fUML Reference Implementation
+### v1.4.0 Release Notes
+
+This is a base release of the fUML Reference Implementation, conforming to v1.4 of the [fUML Specification](http://www.omg.org/spec/FUML/1.4).
+
+**IMPORTANT NOTE**
+
+fUML 1.4 is unusual, in that it's primary purpose is to migrate fUML to UML 2.5.1. Therefore, fUML 1.4 
+has no functional differences from fUML 1.3, but the structure of the fUML syntax and semantics has been
+significantly re-organized to follow the new abstract syntax package structure introduced in UML 2.5.
+The Java package hierarchy for the syntax and semantics implementation classes has been correspondingly updated
+in the Reference Implementation. In addition, while the Java package names are still based on the names of the 
+corresponding UML packages, they are now rendered entirely in lower case, per usual Java convention (e.g., 
+`fuml.semantics.actions` rather than `fUML.Semantics.Actions`).
+
+### fUML Execution Engine
+
+This is a new base release of the fUML Execution Engine. It is identical to the [v1.3.1](./fUML-1.3.1.md) release 
+that tracked the issue resolutions adopted by the fUML 1.4 Revision Task Force (RTF).
+The complete set of resolved issues implemented 
+since the previous [v1.3.0](./fuml-1.3.0.md) base release are listed below. The list of remaining open fUML issues is available at 
+[http://solitaire.omg.org/issues/task-force/FUML15](http://solitaire.omg.org/issues/task-force/FUML15).
+
+The following issues were resolved by the fUML 1.4 RTF:
+
+[FUML 14-9](http://issues.omg.org/issues/task-force/FUML14#issue-42353) Migrate fUML to UML 2.5.1
+
+[FUML 14-10](http://issues.omg.org/issues/task-force/FUML14#issue-42655) The ExecutionFactory class descriptions need 
+to be updated in the specification for CentralBufferNode and DataStoreNode
+
+[FUML 14-21](http://issues.omg.org/issues/task-force/FUML14#issue-42985) Correction to the resolution to issue 14-10
+
+### XMI Loader/Infrastructure
+
+In order to implement the migration to UML 2.5.1, as required by the resolution to OMG Issue FUML 14-9, 
+this base release also updates the XMI Loader/Infrastructure for the new structure of the UML 2.5.1 metamodel.
