+USER VISIBLE CHANGES BETWEEN TAO-2.5.12 and TAO-3.0.0
+=====================================================
+
+. C++11 is now a mandatory compiler feature which is
+  required for TAO
+
 USER VISIBLE CHANGES BETWEEN TAO-2.5.11 and TAO-2.5.12
 ======================================================
 
+. Removed usage of narrow_from_decl and narrow_from_scope
+  from TAO_IDL, use dynamic_cast now that we have RTTI. Any
+  user that has a custom backend should make the similar
+  changes to their own TAO_IDL backend

- * @brief Implement the iterator for CORBA sequences that need
- *        memory management.
- *
- * There are some CORBA sequences that need to manage memory (e.g.,
- * string sequences). Iterators for these classes also need to
- * manage memory and therefore do not use the iterators defined
- * for the generic sequences.
- *
- * Essentially, only the iterators operators that reference and return
- * elements (e.g.,operator*, operator[]) need to be overridden from the
- * behavior provided by the generic sequence iterators. Template
- * specialization code is appropriate here but I couldn't figure out how
- * to make the compiler happy.
- *
- * In lieu of template specialization code separate iterators exist
- * for sequences that manage memory. Here are those iterators.

 This test verifies that proper request interceptor flow semantics
 occur during a given request/invocation.  It does so by executing a
-canned (hard-coded) set of scenarios.  Each scenario excercises a
+canned (hard-coded) set of scenarios.  Each scenario exercises a
 specific flow behavior.  All scenarios correspond to the ones detailed
 in the Portable Interceptor specification (00-04-05).  They are listed
