PLANNED MAJOR CHANGES "SOMETIME IN THE FUTURE" (i.e., exact beta not known)
===========================================================================

. (JTC) provide example Telecom Log Service Persistance Strategies that
  use BerkeleyDB, ODBC, etc.  Refine Strategy interface as required.

. (JTC) autoconf support for tests and examples subdirectories.

. (OCI) Reenable support in the Notification service for BlockingPolicy,
  DiscardPolicy, and OrderPolicy. (Note: BlockingPolicy requires -ORBWaitStrategy rw)

. (OCI) Fix various memory and thread leaks in the Notification Service.

. (OCI) Fix Notification Service use of PacingInterval and MaximumBatchSize.

. (OCI) Fix Notification Service detection of dead consumers.

PLANNED MAJOR CHANGES TARGETED FOR TAO-1.5.2
====================================================

. (Remedy) Finish and integrate new sequence implementation made by
  Carlos O'Ryan. This also includes a rework of the TAO_String_Managers
  and CORBA::(W)String implementations. This is ready in the sequenceupdate
  branch but can't be merged until 1.5.2 because it breaks with vc6.

. (Remedy) Add possibility to set customer allocators to be used by the ORB for
  marshaling and demarshaling

. (OCI) Made TAO compilable when ACE_USES_WCHAR is set

USER VISIBLE CHANGES BETWEEN TAO-1.4.10 and TAO-1.5.0
====================================================

. Fixed Transport to handle incoming fragmented messages propperly, abstract
  interfaces TAO_Pluggable_Messaging and TAO_Transport have been
  modified. Custom transport/messaging implementations require
  interface modification.

. Fix collocation optimisation when a location forward is received directing a
  client to a collocated object.

. Prevent an OBJ_ADAPTER exception when using an object reference containing 
  an ObjectID that corresponds to a collocated IORTable entry.

. Reverted solution that allowed POA-level control over access to
  security-enabled objects due to conflicts with the specification,
  i.e. the  Security::SecQoP* are not server-side policies.

. When suppressing any and typecodes during IDL compilation this will not
  trigger compile errors due to missing any insert operations

. Bug fix in IFR when creating typecodes for nested structs and unions.

. Added support for the --enable-tk-reactor configure option to the
  autoconf build infrastructure to build the TAO_TkResource library.

IDL COMPILER
------------

. Fix problem with missing includes in the skeleton files for imported arg
  trait declarations.

USER VISIBLE CHANGES BETWEEN TAO-1.4.9 and TAO-1.4.10
====================================================

. Fixed a bug, which allowed security unaware clients to make
  invocations on secure objects, when the ORB was configured with
  support for Security::SecQoPNoProtection.

. Fixed Bugzilla #2145, which was preventing the building of
  the IDL compiler on HPUX.

. Added boxed valuetype support to the Interface Repository
  loader.

. Fixed several bugs in the PICurrent implementation

. Fixed GOA factory name

. Fixed -ORBConnectionHandlerCleanup arguments to accept 0 and 1.

. Improved Portable Interceptor implementation.

. Autoconfig improvements.

. Improved Real-time CORBA support for dynamic threads.

IDL COMPILER:
-------------

. Some bug fixes. See bug #2375 and #2390.

USER VISIBLE CHANGES BETWEEN TAO-1.4.8 and TAO-1.4.9
====================================================

. Added new endpoint selector implementation - Optimized
  Connection Endpoint Selector. A member of the tao/Strategies library,
  use svc.conf file to load the OC_Endpoint_Factory object. See
  tests/AlternateIIOP/svc.conf for an example.

. Continued splitting ORB Services into stub, skeleton, and
  implementation libraries.  Changes to the Concurrency Service,
  Property Service, and RTEventLog Admin Service (TAO's RTEvent
  varient of the OMG Telecom Log Service) have been committed.

. Added a new ORB run-time option "-ORBUseLocalMemoryPool [0|1]" which
  controls an individual application's use of TAO's Local Memory Pool.
  TAO can use a local memory pool to satisfy some of its needs for
  heap storage, as it is often more efficient than using the
  platform's default memory allocator. The pool will always grow as
  large as necessary to satisfy memory allocations, but it will never
  shrink. This means that sometimes a process can retain memory that
  it no longer needs. If the default allocator is used then TAO gives
  memory back as soon as it is not needed.
  The UseLocalMemoryPool option selects between using the local memory
  pool or using the default allocator, where 0 means don't use the pool,
  1 means use the pool. The default is still controlled by the original
  compile-time option controlled by the #define TAO_USE_LOCAL_MEMORY_POOL
  which defaults to 1 if not specified.

. Add a property -ORBKeepalive to allow a user to specify that
  SO_KEEPALIVE is set on IIOP connections. See docs/Options.html
  and Bugzilla #2374.

. Add support for RTCORBA::TCPPrototocolProperties::keep_alive, when
  RTCORBA is used, and the application is using a Server or Client
  ProtocolPolicy.

. Refined the Telecom Log Service Strategy Interface.  Added methods
  to fetch/store capacity alarm thresholds, log QoS, and "week mask".
  Rework locking to avoid race conditions and to improve performance.

IDL COMPILER:
-------------

. Fixed bug in computation of repository ids for predefined types.

. Fixed bug in the handling of TAO_IDL_INCLUDE_DIR.

Interface Repository:
---------------------

. Fixed bug in the lookup of a valuetype member's type using its
  repository id.

. Fixed bug in IFR loader in checking for pre-existence before
  creating an entry corresponding to an IDL typedef.

. Fixed bug in lookup when checking for a local name clash.

. Fixed bug in the describe_interface() operation when the IDL
  interface being described has multiple parents.

USER VISIBLE CHANGES BETWEEN TAO-1.4.7 and TAO-1.4.8
====================================================

. Fixed bugs in code generation for interfaces that inherit from both
  concrete and abstract interfaces.

. Subset Anys and TypeCodes to a separate library. If you use Any/TypeCode
  or one of the core TAO libs uses it you should link the AnyTypeCode
  library with your application

. PICurrent is moved to the PI library

. POACurrent has been moved back from PI_Server to PortableServer

. Added IPv6 support for IIOP

. When Any and TypeCode generation is suppressed when compiling IDL
  no typecodes are generated anymore for user exceptions, they are not
  needed for the operation of the ORB

. When making AMI invocation and the send blocks we buffer the message
  and send it out when the transport is available again

. Emulated C++ exceptions are not maintained anymore. We are keeping
  the macros in the TAO code until x.5.1 is out, if nobody sponsors
  maintenance at that moment the macros will be removed from TAO.
  See also http://deuce.doc.wustl.edu/bugzilla/show_bug.cgi?id=2256

. Support the latest AMI mapping, the old mapping will be kept working
  until 1.5.1 has been released. If you need the old mapping add
  the define TAO_HAS_DEPRECATED_EXCEPTION_HOLDER to your config.h
  file before you build TAO and the TAO_IDL compiler

. Added CodecFactory::create_codec_with_codesets to create a codec with
  a specific codeset. See OMG issue 6050 for the background.

. PortableInterceptor::IORInterceptor has been splitted in IORInterceptor
  and IORInterceptor_3_0. If you use IORInterceptors read the ChangeLog for
  the details, maybe you have to update your code!

. Added the new Custom Servant Dispatching (CSD) feature to provide user
  applications with the ability to implement and "plug-in" custom strategies
  to handle the dispatching of requests to servants. This new feature is not
  currently tested for VxWorks. See TAO release notes for more information.

. Added support for an TAO "versioned" namespace.  When enabled, TAO
  library sources will be placed within a namespace of the user's
  choice or a namespace of the form TAO_1_4_7 by default, where
  "1_4_7" is the TAO major, minor and beta versions.  The default may
  be overridden by defining the TAO_VERSIONED_NAMESPACE_NAME
  preprocessor symbol.  Enable overall versioned namespace support by
  adding "versioned_namespace=1" to your MPC default.features file.

. Changed generated signatures of some valuetype member
  accessor/mutator pairs to be consistent with IN
  parameter semantics.

. Added spec-required generation of member-initializing
  constructor for valuetypes. See C++ mapping (03-06-03)
  section 1.17.2. Closes Bugzilla #2270.

. Added default include paths $TAO_ROOT, $TAO_ROOT/tao,
  $TAO_ROOT/orbsvcs, and $CIAO_ROOT/ciao to IDL compiler
  execution, eliminating the need to add them explicitly
  to the command line.

. Added immediate exits to IDL compiler when some name clash
  errors are encountered, avoiding a crash if parsing is
  continued. Closes Bugzilla #2281.

. Changed the behavior of the _default() method (generated
  for IDL unions that have an explicit or implicit default
  case label) to clean up memory used by the freed member,
  if necessary.

. Fixed bug in IDL compiler when handling a native exception
  in an operation declared in Messaging::ExceptionHolder.

. Although not presently supported by CIAO, added error
  checking to the IDL compiler's parsing of IDL home
  primary keys, which constrain the basic valuetype
  syntax in several ways.

. Fixed order of generated base class stub constructor calls
  when the IDL interface has both concrete and abstract parents.

. Fixed a bug in the handling of forward declared interfaces
  that have both concrete and abstract parents.

. Fixed the command line parsing to preserve the literal
  quotes if they are used in an include path that has a space.
  Closes Bugzilla #2219.

. Many changes related to refactoring of Anys and Typecodes
  into a separate library (POC is Johnny Willemsen
  <jwillemsen@remedy.nl>).

. Merging of many Notification Service changes/fixes from OCITAO to
  the DOC version.  These generally addressed stability issues such as
  memory leaks, thread leaks, etc.

. Introduction of the versioned namespaces changed the name of the
  factory function used for dynamically loading the Notification
  Service persistence mechanisms.  See the service configurator file
  in orbsvcs/tests/Notify/XML_Persistence for an example.

USER VISIBLE CHANGES BETWEEN TAO-1.4.6 and TAO-1.4.7
====================================================

. The Telecom Logging Service now supports dynamically loaded Strategies
  which can be used to implement a persistent log record store.  If none
  are specified, a default in-memory hash table implementation is used.

. The CodecFactory is moved to its own library. If you use this in your
  application include tao/CodecFactory/CodecFactory.h and link the
  TAO_CodecFactory with your app

. The ORBInitializer registry, PolicyFactory registry and ORBInitInfo
  are moved to the new PI library. If you use these clases include
  tao/PI/PI.h in your application code and link the new TAO_PI
  library with your application.

. All server side PortableInterceptor support is moved to the new
  TAO_PI_Server library. If you use this, include tao/PI_Server/PI_Server.h
  in your application code and link the new TAO_PI_Server lib

. A new set of examples and support code that show how to set up a
  multicast-based federation of  Notification Services is now available
  in $TAO_ROOT/orbsvcs/examples/Notify/Federation.

. Hard coded loading of services with Service Configurator now uses the
  ACE_DYNAMIC_SERVICE_DIRECTIVE macro which also works when the xml
  version of service config is enabled.

. The Codeset negotiation support is in its own library. The hooks are
  still present in the ORB Core to dynamically load the codeset support
  if needed. This behavior is overridden by the new ORB_init option
  -ORBNegotiateCodesets 0.

. The Boxed Value Type as specified by the OMG is now accepted by the
  TAO_IDL compiler.

. TAO clients now parse the OMG specified TAG_ALTERNATE_IIOP_ADDRESS
  profile component. To generate IORs using that component, add the
  new ORB_init option, -ORBUseSharedProfiles 1.

. Refactored TAO's codeset negotiation feature to be optionally loadable.
  The implementation is now in a separate library, TAO_Codeset. Applications
  not wishing to use codeset support may pass -ORBNegotiateCodesets 0 to
  ORB_init() to avoid loading the library. When building dynamic applications
  codeset negotiation is available by default. For static applications, the
  default is to *not* include codeset negotiation. Staticly linked apps
  needing codeset negotiation support must do two things:
  - Define the new MPC feature "negotiate_codesets=1" in default.features
    and regenerate makefiles
  - Add "#include <tao/Codeset/Codeset.h>" somewhere in their application
    source. Placing this in the source file that includes calling ORB_init()
    is probably the best place.

. Added CORBA::Object::_repository_id() and CORBA::Object::_get_orb()
  as described by the spec.

USER VISIBLE CHANGES BETWEEN TAO-1.4.5 and TAO-1.4.6
====================================================

. The RTOldEvent library has been removed. The RTEvent library has been
  split in a stub/skel and serv library.

. Support for bi-directional communication over SSLIOP.

. Servants are now always reference counted, in accordance with changes
  to the CORBA specification.

. Added a -x option to catior that works like -f except that it reads
  the IOR from standard input rather than from a file. This makes catior
  much more like the unix "cat" command, and enables it to be used in a
  pipeline.

. Changed the precedence rules for the -ORBListenEndpoints (aka
  -ORBEndpoint) so that the host identifier (either hostname or IP
  address) that appears in IIOP profiles is determined thus:

    1. value from hostname_in_ior (if specified);
    2. setting of -ORBDottedDecimalAddresses option;
    3. value for hostname in -ORBListenEndpoints specification;
    4. whatever TAO magically comes up with based on system
       configuration

  A new test (TAO/tests/IOR_Endpoint_Hostnames) verifies the
  operation of this feature.

. Changed the way that Bidirectional endpoint processing happens when
  -ORBDottedDecimalAddresses 1 is in effect. The previous behavior
  always used the setting of the receiver, but that caused problems when
  the sender and receiver were not using the same dotted decimal
  addresses setting.  Bidirectional endpoint processing now uses
  whatever the sender provides as the hostname since that's also what
  will be in that sender's IORs.

. Added a configuration property -ORBIMREndpointsInIOR [0|1] that
  controls whether ImR endpoints are written into persistent IORs. See
  $(TAO_ROOT)/docs/Options.html and bugzilla #2123 for usage.

. Increment the refcount on the servant in the id_to_servant and
  reference_to_servant methods of the POA.

. Improved g++ 4.0 support.  A number of RTTI related problems have been
  fixed, in addition to removal of duplicate internal ORB related
  singleton instances.

. Fixed assertion that occured in some thru-POA collocated calls.

. Fixed CORBA::UnknownUserException Any insertion problem.

. Fixed TypeCode equivalence failure when comparing aliased and
  unaliased TypeCodes of the same type.

USER VISIBLE CHANGES BETWEEN TAO-1.4.4 and TAO-1.4.5
====================================================

. The POA is rewritten so that it uses strategies for its implementation.

. The ImR handling is moved to the new ImR_Client library. If your server
  needs to register itself to the ImR you have to link the new ImR_Client
  library

. The MIOP part of the POA is moved to the GOA. See the latest version of the
  MIOP specification. You have to link now with the PortableGroup
  library and retrieve a GOA instead of the RootPOA.

. Implemented several missing parts of POA functionality as described
  by the latest corba specification. Missing functionality, incorrect
  exceptions, incorrect minor codes and much more.

. Splitted the huge PortableServer.pidl file in several smaller files
  and regenerated all the generated files in the repository.

. Move TAO_ORB_Manager from PortableServer to Utils library, this is a
  helper class.

. The POA has been split in Root_POA and Regular_POA, on this we will more
  in the future so that the Root_POA just pulls in the minimal set of things
  needed.

. The RootPOA now has "RootPOA" as its adapter name, previously it had
  an empty string.  This is required by the CORBA specification, you can
  overrule this by defining TAO_DEFAULT_ROOTPOA_NAME if you want to
  reduce the "RootPOA" string to be shorter, e.g., "".

. Added support for GNU G++ 4.0.  Additional details in ACE `NEWS' file.

. Explicit template support has been dropped for TAO and it is not possible
  to use it anymore.

. CORBALOC/CORBANAME patched a memory leak and fixed performance related
  to the use of defaulted object keys.

. Added support for Visual Age on AIX

. Made it possible to run most ORB core test with VxWorks in a cross host
  scenario where one part of the test runs on the host and the other part
  of the test runs on the VxWorks target

. The skeletons generated by the TAO_IDL compiler have been refactored
  to significantly reduce the size of server applications.  Please see

  http://www.dre.vanderbilt.edu/Stats/

  for metrics that illustrate the magnitude of the reduction.

. New TypeCode implementation that reduces the size of TypeCodes in
  memory at run-time.

USER VISIBLE CHANGES BETWEEN TAO-1.4.3 and TAO-1.4.4
====================================================

. Reimplemented the way that TAO_Transport deals with GIOP headers.  In
  some cases partial GIOP message headers were read and used as if a full
  GIOP header were received. [Bug 1681]

. GIOP fragment handling has changed where a single large allocation and
  copy occurs at the end of a fragment chain instead of an allocation and
  copy for every fragment received.

. The tao-config script has been replaced by pkg-config metadata files
  which are installed in ${prefix}/lib/pkgconfig by the automake build.

. SHMIOP respects now the dotted decimal addresses setting. When this is
  set it uses ip addresses instead of hostnames.

. Removed the usage of the ACE_x_cast macros, we are using the C++ casts
  from now on.  The TAO core libraries will be updated before the x.4.5
  release.

. Removed MPC code that creates unused and unnecessary subfolders in
  Visual Studio projects and makefiles.

. Fixed unclosed temporary file created by the IDL compiler on platforms that
  lack mkstemp. [BUGID:2026]

. Fixed IDL compiler bug related to handling null object references in a
  sequence. [BUGID:2027]

. Made behavior when marshaling null value of an abstract interface similar
  to the behavior of CORBA::Object.

. Made use of 'true' and 'false' with CORBA::Boolean more consistent in TAO
  source code and generated code.

. Fixed bug in code generation for typedefs of IDL arrays that are not declared
  at global scope or in a module (i.e., in an interface, valuetype, eventtype
  or home).

. Fixed bug in code generation of parent operations in AMI ReplyHandler
  interfaces.

. Changed remaining instances of C-style casts in generated code to the
  appropriate C++-style cast.

. Fixed typo in code generation of bounded sequences of CORBA::Object.

. Fixed bug in code generation for attributes which are unaliased bounded
  (w)strings.

. Changed implementation of TAO::Unknown_IDL_Type (a subclass of TAO::Any_Impl
  used when an Any is first decoded from the wire or created from a Dynamic
  Any) to contain its value in a TAO_InputCDR stream rather than an
  ACE_Message_Block*, thus cleaning up alignment and memory management code
  related to this type.

USER VISIBLE CHANGES BETWEEN TAO-1.4.2 and TAO-1.4.3
====================================================

. New pluggable protocol for GIOP over HTBP, known as HTIOP.  Source in
  orbsvcs/orbsvcs/HTIOP.

. All TAO-specific vendor IDs are now found in the "TAO" namespace.
  Documentation for these constants has also been improved in a number
  of cases.

. Further reduced inter-header dependencies, which should improve
  compilation times for TAO and TAO applications.

. Fixed memory leak in CDR encapsulation Codec's encode_value() method.

. Modified PerlACE scripts for Tests/test environment to allow
  per-platform customization of process startup delay.  Used the changes
  in various run_test scripts.

. SyncScope::NONE blocks during connects [Bug 1476].

. Improved compatibility with JDK orb.

. Added Wait on LF No Upcalls (MT_NOUPCALLS) wait strategy.  However,
  recent experiences with it indicate there may be problems in scenarios
  other than its original motivating case (see ChangeLog).  This feature
  should be considered EXPERIMENTAL, and use it at your own risk.

. New CORBALOC parsing is available. This feature allows TAO clients to
  use any third-party pluggable protocol in corbaloc strings.

. Fixed bug that caused memory fault when incoming object reference
  contains an unknown profile.

. Fixed problem in some modules when platform lacks unsigned long long
  support.

. Modified catior to allow decoding of additional protocols.

. The PortableServer library isn't depended anymore on the
  ObjRefTemplate and IORInterceptor libraries.  ObjRefTemplate and
  IORInterceptor are loaded on demand and depend on PortableServer.

. IDL compiler can be built for environments that lack unsigned long
  long.

. Reduced the amount of code generated by the TAO_IDL compiler when
  using forward declarations.

. Naming Service implementation memory leak fixes.

. Split ORB Services into stub, skeleton, and implementation libraries.
  Changes to the Naming, Trading, Event, Notification, and Logging
  Services have been committed.

. Common utilities (tao_imr, tao_ifr, nslist, nsadd, nsdel,
  NamingViewer) now installed in $ACE_ROOT/bin.

. Changed #includes of orbsvcs header files to be consistent.  The
  pathname now always contains a "orbsvcs/" prefix.

. Notification Service EventReliability and ConnectionReliability QoS
  have been added to bring the DOC version of Notification Service
  into feature parity (in this area) with OCITAO's 1.3a version of the
  Notification Service.  Note that due to changes between 1.3a's
  source base and DOC's 1.4.3 source base, this is a re-implementation
  of the changes and not a simple port.

  In addition to the changes made directly to the Notification Service
  a number of test and example programs have been created for the
  reliable notification service. These programs may be found in
  subdirectories of $TAO_ROOT/orbsvcs/tests/Notify. A README file
  in each directory provides more detailed information, and a run_test.pl
  script is included to run the example or test.

. A change has been made to the Notification Service IDL to improve build
  times and reduce the Notification Service footprint. The change suppresses
  the generation proxy and stub code for the many interfaces that are
  specified by the OMG, but are not implemented in TAO.

. Implementation Repository refactored to allow the locator and
  activator to be used as services in the ACE Service Configurator
  framework.  The locator and activator services have been split into
  separate libraries and executables.  There have also been
  miscellaneous bugs fixed and performance enhancements made.

. Fixed Load Balancer binary generation problem.  Libraries were being
  created rather than executables.

. Work around MSVC++ 6 namespace brain damage in new Security/SSLIOP
  code.

. Fixed memory management problem in SecurityLevel3 code.


USER VISIBLE CHANGES BETWEEN TAO-1.4.1 and TAO-1.4.2
====================================================

. Overall
  - Support for g++ 3.4.1.
  - Support added for latest HP aCC compiler.
  - Improved Doxygen documentation.
  - Reduced header file dependencies, which should speedup compilation
    and help minimize static footprint.

. ORB
  - Fixed memory leak in DII exception handling.
  - Fixed insertion of label values when creating a union type code
    with create_union_tc().
  - Support for retrieving AMI and AMH reply handlers from a local
    memory pool.
  - Fixed location forwarding to collocated objects.

. POA
   It is now possible to pass user-defined policies unknown to the
    POA with corresponding registered policy factories to the
    POA::create_POA() method via its policy list parameter, as
    required by the CORBA specification.

. TAO_IDL
  - Closed security hole on platforms that support mkstemp() function.
  - Fixed potential buffer overrun problem.
  - A number of scoped name bugs have been fixed, including some
    workarounds for MSVC++ 6 scope resolution problems.
  - Fixed mixing of *Implicit and *Explicit inheritance lines when the
    there is a chain of inheritance in component homes.
  - Improved error checking of component and home declarations.
  - Code generation for valuetypes that support one or more abstract
    interfaces.
  - Added new "-GA" option that causes CORBA::Any operators and
    TypeCode bodies to be generated in a separate "fooA.cpp" file.
    Helps reduce footprint for applications that do not use Anys or
    TypeCodes.
  - Added required _downcast() method to generated value factories.
  - Disabled generation of implementation class for abstract
    interfaces.
  - Removed support for reading an IDL file from stdin.  This feature
    is legacy code used for debugging the IDL compiler in the early
    days of its implementation, and is not useful in application
    situations.
  - Generated stub/skeleton inline files now end in ".inl" instead of
    ".i".  The latter is generally used as the extension for
    pre-processed C sources.
  - Process multiple IDL files in a single execution by iteration
    in a single process, rather than spawning a process for each
    file as before.
  - Added the remaining spec-defined sequences of predefined types
    to the CORBA namespace in TAO.

. Added CPU utilization load monitor to TAO's Cygnus load balancer.

. Added basic CSIv2 support, which is the latest CORBA Security
  architecture specification.

USER VISIBLE CHANGES BETWEEN TAO-1.4 and TAO-1.4.1
==================================================

ORB
---
.  Changed the name of a parameter to the TAO type code
   internal method to avoid a name clash with STL.

. Added the spec-required ostream insertion operator for
  CORBA::Exception* to go with the existing ostream
  insertion operator for CORBA::Exception&.

. Moved the above ostream insertion operators into the
  CORBA namespace, so they cannot be accidentally hidden by an
  application.

. Moved the declaration of Any operators for some ORB
  types so that the corresponding definitions may
  remain unlinked if the Any operators are not used in
  an application.

. Fixed typo in type code factory code that is compiled
  only when ACE_SWAP_ON_WRITE is defined.

. Several fixes to MakeProjectCreator (MPC) files, which
  generate GNU makefiles, Borland makefiles, and Microsoft
  Visual Studio project files.

. Fixed Any insertion and extraction operators for bounded
  strings and wstrings to prevent an error if they are
  inserted as bounded with bound 0 and extracted as
  unbounded, or vice versa.

. Deprecated the TAO-specific _type() method for exceptions.
  which is no longer used anywhere in TAO, and is retained
  solely for backward compatibility.

. Fixed bug in TAO_SSLIOP pluggable protocol that prevented large
  requests from being sent.  [Bug 1429]

. Cleaned up interceptor memory leaks that occurred when
  CORBA::ORB::destroy() was called.

. Fixed problem where a ServerRequestInterceptor could be called after
  the ORB was shutdown.  [Bug 1642]

. Overhauled PICurrent support to fix several problems. [Bug 1215, 1738]

. SSLIOP documentation is now available.

. Fixed memory leaks in servers when the ORB is operating in a
  thread-per-connection  mode. This problem showed up when clients
  keep connecting and disconnecting from the servers.

. Fixed memory leaks in AMI clients that connect to a servers over
  unreliable connections that keeps getting dropped.

. Fixed a race connection in Any_Impl implementation.

. Fixed a byte order problem with DSI gateways

. Added support for OVATION to work with this BFO of TAO.

IDL COMPILER
-------------

. Changed the names of some local variables in generated
  operation code, to reduce that chance of a name clash.

. Fixed bug where a #pragma version directive is sometimes
  not reflected in the generated repository id.

. Disambiguated generated template instantiations for array
  _var, _out and _forany classes, when two or more arrays
  have the same element type and bound.

. Added check for a name clash between a valuetype member
  and the first segment of a scoped name referenced in
  the valuetype.

. Fixed incorrect code generation for the CDR operator of a
  struct/union/exception with an undefined forward declared
  interface member.

. Fixed incorrect code generation for operation arguments
  that are typedefs of char, octet and boolean.

. Fixed bug in handling complex recursive types.

. Added -GId command line option to generate line and
  file debug info in *I.* files, similar to what is
  already generated in *C.* and *S.* files. This debug
  info generation is now off by default in *I.* files.

. Fixed the handling of included orb.idl file to generate
  corresponding C++ includes for the files orb.idl
  itself includes, which contain spec-required declarations
  of sequences of basic CORBA types.

. Fixed generation of ORB file includes triggered by the
  presence of one or more abstract interfaces in an IDL file.

. Added check to the generation of _setup_collocation()
  method for abstract interfaces, to make it more robust.

. Added a version of the realpath() system function that
  can be used with LynxOS, which does not have a native
  version.

. Fixed code generation for bounded strings and wstrings
  when they appear anonymously (without a typedef) as operation
  parameters.

. Fixed code generation of flat names for AMI-related types.

. Fixed errors in code generation of sequences of components
  and eventtypes.

. Fixed code generation of CDR operators for aggregate types
  that contain one or more abstract interfaces.

. Fixed bogus errors produced when there are repeated forward
  declarations of an interface.

. Fixed errors in some use cases of the propagation of a #pragma
  prefix directive to nested scopes in generated repository ids.

. Fixed errors in code generation for attributes in Asynchronous
  Method Handler (AMH) classes.

. Fixed a bug that caused the IDL compiler to crash when it sees
  certain kinds of illegal IDL.

. Fixed problems in the interaction of checks for local interface
  and for null object reference when marshaling an interface
  member of an aggregate type.

. Fixed generation of operations inherited by a local interface
  from a non-local one - these operations must be regenerated
  as pure virtual.

. Added a space between some generated template parameter
  opening brackets and a leading double colon of a fully
  scoped name, since some compilers would read "<:" as
  the digraph character for ']'.

. Fixed bug in code generation for an array of typedef of
  string and wstring.

. Fixed a bug in the generation of repository ids for
  explicit, implicit and equivalent interfaces for component
  homes.

. Fixed bugs in the generation of marshaling and demarshaling
  code for aggregate types with component or eventtype members.

ORB SERVICES:
-------------

IFR:
---

. Fixed bug in creating entries for attributes, which in CORBA 3.x may
  have separate get- and set- exceptions lists.

. Added some method overrides to disambiguate multiple inheritance
  problems some compilers would have in classes added to support CORBA
  3.0 extensions.

. Fixed bugs in entering attributes of abstract and local interfaces,
  and in querying for attributes of components.

. Added a "-m" option to IFR_Service to enable multicast discovery of
  the service.

LOAD BALANCING
--------------

. Added two new strategies, namely LoadAverage and LoadMinimum.

NOTIFICATION SERVICE:
---------------------
. Corrected the implementation to add the caller's <subscribed_types>
  to the Admin Object's types. This solves the problem that if a
  proxy's connect_structured_push_consumer() is called *AFTER* the
  proxy's subscription_change(), then the subscriptions do not work.

. Added the -NoUpdates option to the Notification svc.conf
  options. If this option is specified, the
  subscription_change/offer_change messages are NOT sent to proxy
  objects.  This option is useful to turn off entire updates for
  applications that do not reply on subscription_change/offer_change
  messages.


USER VISIBLE CHANGES BETWEEN TAO-1.3.6 and TAO-1.4
==================================================

IDL COMPILER:
-------------
. Fixed bug related to the order of #pragma prefix and #include
  directives

. Fixed bug in generation of copy constructor for AMH interface
  classes.

. Fixed incorrect handling of a parameter name in an AMI sendc_xxx
  operation that clashes with a C++ keyword.

. Readded the generation of _unchecked_narrow () back into the stub
  code since it is required by the latest OMG CORBA specification.

CORE ORB
-------

. SCIOP endpoints are not created by default. They need explicit
  specification of -ORBEndpoint sciop:// at startup.

. Fixed a bug that caused the ORB to dump a core when server side
  interceptors returns an exception and if the operation parameters
  contains a sequence an out parameter.

. Fixed a bug that caused extraction of basic data types that are
  aliased from an Any.

. Added a couple of regressions tests for some of AMH features.

. Lots of other bug fixes (see the bottom of this message for a
  complete list of bugzilla bugids fixed in this beta).

. Fixed a problem with dynamic loading of the ORB. This was introduced
  by "magic" static constructors in the TAO PortableServer headers
  where dynamic loading/unloading of the ORB failed.

. Added an option, -ORBDisableRTCollocation which allows users to
  disable the RT collocation technique used by TAO and fall back on the
  default collocation technique used for the vanilla ORB.

. Prevent the TP_Reactor used within TAO from exiting when it receives
  a EINTR during select ().

ORB SERVICES
------------

. Added new security variable so that libTAO_Security could be built
  independently of libTAO_SSLIOP, and set the default to true.

. An initial implementation of the FTCORBA spec has been added to
  TAO. This release features an initial cut of ReplicationManager,
  FaultNotifier, and a FaultDetector. Please see

  $TAO_ROOT/orbsvcs/tests/FT_App/README

  for a simple example that uses the different FTCORBA features that
  have been implemented in TAO.

. Fixed a bug, in PG_ObjectGroupManager::remove_member () methods
  which caused the group entry to be available in the location_map
  when a member of the object group is removed.
