version 2.3.1

- Fixed CORBA::InterfaceDef::describe_interface(), which must include info
  for inherited ops and attributes as per 2.3 spec. Fixed code that depended
  on the old behavior.
- workaround for VC++ namespace problems in generated OBV code
  (Andreas Rudolf)
- fixed bug for coercions between bounded and unbounded strings
- Don't assert(0) if POA initialization fails (i.e. -POAImplName without
  an option), but throw an exception instead. (Carsten Zerbst)
- Added support for file: and http: URI's according to the INS spec. (See
  also RFC 1630). Referenced files must contain a single IOR. HTTP client
  speaks 0.9 so far.
- ird, micod and nsd now sport a `--ior' option to write their object
  reference into a file. Therefore, you can now connect to a Naming Ser-
  vice in an entirely CORBA compliant manner: `nsd --ior /tmp/nsd.ref',
  then run `client -ORBInitRef NameService=file://localhost/tmp/nsd.ref'.
- Got rid of local static objects, which cause problems when MICO is used
  as loadable module.
- fixed CORBA::ORB::poll_next_response() and CORBA::ORB::get_next_response()
- do not enter dispatcher in CORBA::Request::poll_response()

  but only reserve space for "len" element as per CORBA 2.3 spec
- CORBA 2.3 specifies a Any::type(CORBA::TypeCode_ptr) method that conflicts
  with the existing method. renamed old method to set_type() and implemented
  reimplemented type() to conform to the CORBA 2.3 specs
- moved part of README-WIN32 to the docs

      union U switch (T1) {
      case L1:
      case L2: sequence<T2> x;
      };
- IDL Compiler:
  * added new option --gen-included-defs to generate code explicitly for
    #included definitions
  * added new option --gen-full-dispatcher which will add dispatching code
    in the skeleton of an interfaces for all inherited operations and
    attributes
  * added new option --codegen-midl to generate Microsoft MIDL out
    of a CORBA IDL specification (Massimo Di Giorgio)
  * removed backend for IDL to C mapping. The following options are
    no longer available: --codegen-c, --no-codegen-c, --h-suffix
  * many C++ mapping bug fixes (OpenGroup)
  * added missing support for coercing unsigned long long to other basic types
  * changed TypeCode::equal() to follow recursions if remove_aliases==TRUE
    to prevent idl compiler from generating duplicate sequence marshallers
    as in
      struct S1 { sequence<S1> s; };
      struct S2 { sequence<S1> s; };
    where sequence<S1> marshaller was generated twice.
  * the skeleton code does no longer automatically free the old value of
    a variable length inout param (string, wstring, (abstract) interface,
    valuetype, valuebox) if the user replaces the value; that is the
    user has to free the old value if he wants to replace it. This is
    the way the CORBA spec wants it. REQUIRES CHANGES IN USER CODE.
  * fixed memory leaks in non-copying Any extraction operators: ownership of
    the extracted value is maintained by the Any and user must not delete it.
    This affects the non-copying extraction operators for: string, wstring,
    (abstract) interface, valuetype, valuebox, struct, union, exception,
    sequence, array. REQUIRES CHANGES IN USER CODE.
  * generate more efficient skeleton code for variable length out parameters
    and return values.
  * generate more efficient method dispatchers for interfaces with
    lots of methods.
  * generate more efficient marshalling code for sequences and arrays
    of base types.
  * new option --config to print some important MICO configuration infos.
  * fixed memory leak in generated SII demarshallers for (abstract) interfaces
  * cleaned up VC++ workarounds
  * "export" is now a C++ keyword

  to use the POA
- added support for LynxOS in configure.in (Hans-Joachim Baader)
- made configure recognise OpenNT C++ compiler

  precompile header files to speed up compilation (currently only supported
  for SGI C++ 2.7.1)

    proxies (reported by Christophe Rene)
  * fixes for SGI C++ Compiler 7.2.1 (Marc Stuessel)
  * also list services in list_initial_services() that register on demand
  * notify callbacks when dispatcher moves events to a new dispatcher (bug
    reported by Leif Jakobsmeier)
  * install CORBA-SMALL.h
  * made auxdir/qtmico.cc and tools/ir-browser/dii.cc compile again
- POA:
  * speedup for some common use cases
  * changed Active Object Map to handle large numbers of objects
    more efficiently
  * fixed _get_interface
  * updated ServantManagers to more closely follow the specs. The
    ServantManager skeletons don't derive from CORBA::Object any
    more
  * updates for CORBA 2.3 (RefCountServantBase et al.)
  * upon shutdown, the POAManager now signals running services a
    SIGTERM and waits for them to terminate (giving them a chance
    to save their state)
- IDL compiler:
  * if an object has an empty repo id (like objects generated by the
    interoperable naming service extension) always query the server
    for narrow (i.e., behave as if --query-server-for-narrow was
    specified if the repo id is empty)

version 2.2.4

- added CORBA::Bounds exception and made the DII use it

- use idl compiler to translate ioptypes.idl and ssliop.idl
- set the completion status of system exceptions to MAYBE or YES instead
  of NO where appropriate
- optimized micod by using GIOP location forwarding, so that using micod
  no longer introduces a performance drawback. This relies on two client
  side GIOP features some CORBA implementations do not support although
  prescribed by the CORBA specification: 1) resending of outstanding
  invocations when CloseConnection is received and 2) fallback to original
  unforwarded object reference when connection to forwarded location
  fails. Therefore this feature must be explicitely enabled by giving
  micod the --forward command line option.
- renamed "_not_existent" to "_non_existent" as per CORBA spec
- changed BOA to forward all requests to mediator after deactivate_impl()
  or deactivate_obj() has been called
- changed IIOPServer to orderly shutdown (send a CloseConnection message on)
  all open connections upon ORB::shutdown()
- fixed client side location forward handling: must fall back to
  the original unforwarded IOR when the connection to the forwarded
  location breaks
- added Trading Service (Torben Weis)
- added "Success Stories" section on web page
- use of namespaces is now on by default (use --disable-namespace to avoid
  using namespaces)
- moved DynAny to libmico (libmicoaux is still there but is empty). also
  use idl compiler to generate DynAny declarations.
- replaced assertions by throwing appropriate exceptions in libmico.
  new configure option --disable-orb-excepts to turn this off (i.e.,
  revert to pre 2.2.4 behaviour)
- added configure options to selectively turn on services (Karel Gardas)
- Initialize POA when first referenced. Also solves bootstrapping problem
  with micod.
- new way to reduce compilation times and compiler memory usage by cutting
  down the code included by CORBA.h. There are two ways to go:
  1) before including CORBA.h #define MICO_CONF_NO_X to turn off feature
     X (where X can be IR, IMR, POA, INTERCEPT, DYNANY).
  2) before including CORBA-SMALL.h #define MICO_CONF_X to turn on feature X
- changed implementation repository and related tools to store a tag
  along with each repository id. when bind()ing to an object with a
  specified tag micod will now only launch servers that implement objects
  with given tag and repoid. see demo/account2/account script for how to
  tell micod the tag.
  IMPORTANT NOTE: if an object has a non-empty tag you MUST tell micod the
  tag; otherwise bind()ing to the object will fail.
- updated property service; wrote propertyd demo (Leif Jakobsmeier)
- added simple IIOP firewall support for use with TIS plug-gw (see
  www.technosec.com for details) (Rudolf Schreiner)
- print better error message when IIOPServer::listen() fails (Stefan Wille)
- redo invocations when CloseConnection is received before the reply
  arrives to fix interoperability problems with ORBs that close idle
  connections automatically (reported by Jennifer Harris)
- add POA support in imr_impl.cc (Karel Gardas)
- initialize variables in GIOPCodec ctor before using them (Greg Banks)
- Added demo for random.org (Frank Schneider)
- Added iordump utility
- bug fixes:
  * when a client called a server and the server called back the client
    a client crash made the server crash as well. fixed this
  * fixed bug in StaticRequest::invoke() (invocation was sent twice
    after a forward)
  * fixed bug in IIOP code: GIOPConn::do_read() must not continue if
    the callback deleted the connection
  * fixed bug in TypeCode::equal(): must compare the element types of
    recursive sequenes, not only the recursion depth.
  * fixed bug in TCSeqObject::marshal() and TCSeqObject::demarshal()
  * fixed bug in GIOPInContext and GIOPOutContext, which caused memory
    being freed twice in some circumstances
  * fixed bugs in configure script (reported by Doug Anderson)
  * fixed bug in marshalling of recursive type codes
  * fixed bug in IIOP server side locate request processing which caused
    a server to hang forever whenever a locate request was received (reported
    by Nikolaj Logvino)

    function is called (Chin Huang)
  * fixed prg target in auxdir/Makefile (reported by Mike Sample)

  * Fixed bug in GTK config (Marc G. Fournier)
- Win32 changes:
  * more Win32 improvements and bug fixes (Rudolf Janz, Martin Sander)
  * lots of changes for Win32: most makefiles are in place now, micod
    and some services work now (Rudolf Janz)
  * MICO can now be compiled under Windows95
- changes for CORBA 2.3:
  * added new system exceptions
  * updated Policy support

  * added replace(), release(), and get_buffer() methods to sequence templates
  * changed Any::from_fixed and Any::to_fixed to match the spec
  * renamed _narrow() to _downcast() for exceptions
- IDL compiler:
  * emit Any marshalling code for types in --pseudo interfaces
    (see ORB::create_policy for rationale).
  * fixed problem with POA ties inheriting from interfaces in a module
    (reported by Markus Pohlmann)
  * fixed bug in operation dispatcher of server skeleton (Gerd Aschemann)
  * fixed mapping of types in container types (structs and unions)
  * fixed #pragmas directly after an #include
  * added missing constructor for member initialization of
    exceptions (reported by Doug Anderson)
  * fixed c++ mapping for wchar IN parameters
  * the Static Invocation Interface (SII) is now being used by default.
    The SII makes the marshalling of parameters much faster. The old
    marshalling code that makes use of the DII can be activated via
    --use-dii. Support for Any and TypeCode must now be activated
    explicitly via options --any and --typecode.
  * made <<= and >>= operators use the SII marshallers
  * do not generate Any marshalling for --pseudo unless --any is on
  * new option --c++-skel that causes the idl compiler to emit
    code needed only by servers into a separate file <name>_skel.cc
  * reduced size of generated code:
    - moved client side exception handling code to mico_sii_throw()
    - emit server side try-catch code for system exceptions only once
      per interface instead of once per method
    - omit generation of StaticTypeInfo::copy() to avoid instantiation
      of copy constructors for the associated type

  exception classes is still generated but throwing them will result in
  an error message and program abort.
- added manual pages for nsadmin and nsd.

version 0.9b1

- added "activate" subcommand to imr to force activation of an implementation
  (needed for servers that register with the naming service).
- objects are now restored on demand (i.e., when invoked). before 0.9b1
  all objects were restored at server startup.
- bind() can now distinguish between objects of the same type by passing
  it the BOA::ReferenceData of the requested object; see demo/account2 for
  an example.
- made Object::_get_interface() and Object::_is_a() work.

  no code is generated for included files, instead foo.h is included. that
  means you have to run all #included files through the idl compiler by hand.
  the advantage is that you can now build libraries of CORBA objects.

  for runtime binding, see demo/shlib for an example
- support for installing a user defined identifier (BOA::ReferenceData)
  in object implementations, see demo/account2 for an example
- MICO provides now four wrapper scripts mico-c++/mico-ld and
