 USER VISIBLE CHANGES BETWEEN ACE-6.4.1 and ACE-6.4.2
 ====================================================
 
+. Added support for getpwnam_r on Solaris 11
+
+. ACE_OSTREAM_TYPE uses the std namespace where applicable
+
+. ACE_WIN32_Asynch_Operation::cancel() uses CancelIOEx on Windows Vista and
+  above
+
+. Bugfix of exported template specializations on Win32 platforms
+  (specifically, ACE_Condition_Recursive_Thread_Mutex)
+
+. Fixed potential memory leak when using the ACE_WIN32_Proactor
+
+. Header sanitizations (specifically, ace/Synch.h)
+
+. Fixed a race condition in ACE_Thread_Manager::task_wait() on Win32
+
+. A (major) cleanup of timer queue code
+
+. Repaired the ACE_Timer_Hash class. This class code was unused for a while
+  and essentially broken due to bit-rot. It is now another (meta-)implementation
+  that can be used stand-alone, or with the other timer queue implementations
+
