+USER VISIBLE CHANGES BETWEEN ACE-5.4.1 and ACE-5.4.2
+====================================================
+
+. Support for g++ 3.4.1.
+
+. All ACE Makefiles, project files, etc, are now generated by OCI's
+  "MakeProjectCreator" (MPC) tool.  Makefiles and project files for
+  commonly used configurations have been pre-generated and distributed
+  with the beta(s).  Please see:
+
+  $ACE_ROOT/ACE-INSTALL.html
+
+  for information on how to use MPC with ACE.
+
+. Improved Doxygen documentation.
+
+. Reduced header file dependencies, which should speedup compilation
+  and help minimize static footprint.
+
+. ACE now requires support for the following standard C++ features:
+
+  - "bool" keyword
+
+  - "mutable" keyword
+
+  - "explicit" keyword
+
+  - C++ casts (e.g. static_cast<>, reinterpret_cast<>, dynamic_cast<>
+    and const_cast<>)
+
+  If you're using a compiler that does NOT support these features
+  please contact Steve Huston <shuston@riverace.com> for support.
+
+. Changed the select()-based reactor implementations to scan for
+  broken handles to remove based on the registered handles, not on
+  event handlers.  This allows for bad handles to be removed from the
+  reactor even if the event handler doesn't implement get_handle() the
+  way we expect.
+
+. Support for Pthreads native recursive mutexes was added. This
+  capability is specified to ACE_OS::mutex_init() as an optional
+  argument, lock_type. To fix confusion from an earlier attempt to add
+  this functionality, the meaning of the old 'type' argument to
+  ACE_OS::thread_mutex_init() is changed. It previously combined the
+  scope and type. Now it is just the type (e.g. recursive), as the
+  scope is inherent in the method used. For clarification on
+  ACE_HAS_RECURSIVE_MUTEXES, it means that the platform is capable of
+  them, not that they always are, as one would expect. However, before
+  Pthreads had recursion added, it was never optional. Now it is.
+
+. Initial support for new Linux sys_epoll() interface in
+  Dev_Poll_Reactor.  The obsolete Linux /dev/epoll interface is no
+  longer supported.
+
+. Improved Cygwin support.
+  - Threading works without problems.
+  - Problems with shared memory, process shared mutexes, multicast and
+    some other small things still exist.
+
+. New OpenVMS port.
+  -  This is for the latest version of OpenVMS with all available ECOs
+     applied. Basic stuff works without problems.  Advanced features
+     still need some work.
+
+. Usage of ASYS_INLINE is deprecated in ACE, use ACE_INLINE instead.
+
+. Autoconf support has been improved and fixed on a number of
+  platforms, including the BSD variants (e.g. FreeBSD).  It is still
+  not the preferred way to configure most platforms, but it is ready
+  for wider testing. Please report any problems found to
+  ace-bugs@cs.wustl.edu.
+
+. A number of fixes were made to quiet compile errors and warnings on
+  64-bit Windows.
+
+. For builds on AIX using Visual Age C++, the make rtti option default
+  was changed to 1, enabling RTTI by default.
+
+. ACE_Service_Repository::remove() has a new, optional argument that
+  can receive the service record pointer for the removed service. If
+  the pointer is returned to the caller, it is not deleted. If the
+  pointer is not returned to the caller (the default) it is deleted
+  (this is the historic behavior).
+
+. The tutorials in ACE_wrappers/docs have been removed. They were not
+  being maintained and caused confusion in a number of cases. Now that
+  there are complete examples that match the printed books (C++NPv1,
+  C++NPv2, APG), the older tutorials are no longer useful.  Please see
+
+  $ACE_ROOT/examples/C++NPv1/
+  $ACE_ROOT/examples/C++NPv2/
+  $ACE_ROOT/examples/APG/
+
+  for the source code of the examples in those books.
+
+. ACE_String_Base::fast_clear() is a new method which sets the string
+  length to 0. Doesn't release string-allocated memory, but if the
+  memory was externally supplied, it is no longer referenced from the
+  string object.
+
+. A true C++ "bool" is now used as the CDR stream boolean type, if
+  supported by the compiler.
+
+. Renamed AIX 5L configuration header from config-aix5.1.h to
+  config-aix-5.x.h.
+
+. All C++ equality, relational and logical operators now return bool
+  instead of int, as is the norm for modern C++.
