 * Flang is now included in the binary packages released by LLVM.
 
+* The debuginfo-test project has been renamed cross-project-tests and is now
+  intended for testing components from multiple projects, not just debug
+  information. The new "cross-project-tests" name replaces "debuginfo-test" in
+  LLVM_ENABLE_PROJECTS, and a new check-cross-project-tests target has been
+  added for running all tests in the project. The pre-existing check-debuginfo-
+  test target remains for running just the debug information tests.
