Some of the changes / new features include:
-------------------------------------------

* Moved to new JDK, JacORB, and ACE/TAO versions.
   - j2sdk 1.4.1_rc1
   - JacORB 1.4.1
   - ACE/TAO 5.2.4/1.2.4 (except WinNT which uses 5.2/1.2)


quoSecurity:
  * quoOODTE made work with JacORB 1.4.1

quoCore:
  * simple example C++:
   Add CORBA macro and makefile fixes

  * switch qosket C++ and simple example C++:
   ACE environment macro fixes

  * Sliding Window Counter Syscond Implementations for C++:
   QUO_SWEventCounterSCImpl counts events over a window.
   QUO_SWMeanRateCounterSCImpl computes the mean rate of event
   occurance over a window.

  * quogen:
   - Add ACE_THROW_SPEC(( CORBA::SystemException )) in client side delegate
   - RegionSeq* -> RegionSeq_var. Prevents leak on contract eval in
     delegate.
   - fixed namespace clash when having multiple contracts with same region
     names within the same kernel
   - fixed various boundary check bugs which caused quogen to segfault
     under NT
   - added checks to allow delegates to be generated with no contract
     defined
   - Made relative operators binary, expressions such as x<y<z are no
     longer legal.
   - check for NULL pointers for _qosket_interface and
     _business_interface, to prevent crashing on erroneous input

  * QuoKernel:
   - added RSS C++ interface
   - revised naming of generated NT libraries to adopt ACE/TAO scheme
   - bug fix: revised implementation of usage of cached allocators for
     syscond value sequences.
   - fix eventType references in c++ kernel sources
   - fully specify _downcast operation in System Conditions to point to
     correct Skeleton methods
   - Make RemoteValueSCMonitors more usable:
         Make MonitorSC inherit from ReadOnlyValueSC
         Add setPollRate operation to Monitor interface
         Adjust C++ and Java Impls accordingly
   - Fix memory leak in QUO_RemoteValueSCMonitorImpl

  * RSS:
  - DataScopes can now create their parent
  - external interface now supports string based Path specifications
  - DataScopes can now be dynamically removed
  - Proxy Formulas were added to allow dynamic changing of DataScope
    containment hierarchy
  - AlarmDS allow for reporting periodic formula changes
  - Changed DataValues now return new DataValues instead of modifing
    internal Values
  - Many Threading bugs were fixed

* Iperf
  - created iperf servers to periodically measure the bandwidth between
    hosts
  - Exported bandwidth measurements in Wiki format
  - Exported bandwidth measurements in RSS format

QuO 3.0.10 got released today.

You can download it at
http://qualityobjects.org/release/3.0.10/

Some of the changes / new features include:
-------------------------------------------
quoCore:
  * Made memory allocation policy flexible for C++ Kernel contract
    evaluation. With the use of ACE_Allocator objects, it is now possible
    to minimize the number of dynmamic memory allocations during contract
    evaluation (this is believed to cause memory fragmentation problems
    on VXworks).

  * Extended support for building quogen and the C++ Kernel under NT:
    It is now possible to build both release and debug versions.

  * various changes to move up C++ support to TAO version 5.2

  * New example $QUO_ROOT/examples/brokered_imgsvc, which is a model
    application containing a display client, a slide server, and a broker
    that connects the previous two together.

  * Expanded the bette example to use a webcam as picture source.
    Also added a new qosket $QUO_ROOT/qosket/img_resize to do dynamic
    image resizing.

quoAQuA:
  * First release of quo-enabled AQuA (quoAQuA). Now works with version
    ITUA-AQuA 4.0.6 and jacorb 1.4.

quoUAV:
  * updates shown at the PI meeting April 2002.


quoDoc:
  * moved to new webpage
  * added section about quoAQuA



Known issues:
-------------
quoOODTE:
  * the cpp part of the test is not compiling. [ccjones, April 4 2002]

quoCore:
  * examples/brokered_imgsvc
    The webcam support has only been partially tested.

quoRsvporb:
  * examples/bette_rsvp is out of date. It compiles but does NOT run.

QuO 3.0.9 has been released today.

You can download it at
http://www.dist-systems.bbn.com/tech/QuO/release/latest/index.html

  If you are using quo on NT be advised that quogen is exhibiting some
odd behavior with the simple example. We are looking into this and
hope to get to the bottom of this problem soon.

Some of the changes / new features include
------------------------------------------

-- added a new constructor to server side delegate and adaptor for RMI
to handle socket factories. An RMISocketFactory can now be passed in
as an arg to this cons. This was a change request from Rich Shapiro.
   [Partha Nov 19 01]

QuO 3.0.8 got released today.

You can download it at
http://www.dist-systems.bbn.com/tech/QuO/release/latest/index.html


Some of the changes / new features include
------------------------------------------

- added new example brokered_imgsvc: It is a version of the famous bette example
   hookup up to a webcam.
   [Michael, Oct 23 01]

- added support for explicitly naming adapter class with --adapter.
   Also, if neither --adapter nor --businessqosket are present, the name of
   the adapter class will be the value of --business appended by "Adapter".
   [Michael, Oct 23 01]

- Various fixes and improvements to the JacORB version of OODTE.
   Status:
   - every request and reply is now digitally signed and verified;
   - sequence numbers to detect replay have been added but are currently
     disabled because nested invocations are not handled correctly;
   - exceptional replies are not handled correctly;
   - the OODTE test suite is improved to test multiple clients invoking
     concurrently on multiple servers, using a wider variety of test methods;
   - the OODTE interceptors now are not installed if both .ini files
     they need are absent (this allows OODTE to be switched on or off
     depending on .ini files rather than on command-line switches);
   - Visibroker version of OODTE is still broken.
   [Franklin, Oct 23]

- added support for qosket generation without contracts. This works in
combination
   with the --delegate flag to set the name of the generated delegate class.
   This should be useful to clean up the UAV code in terms of eliminating dummy
contracts.

QuO 3.0.7 got released today.

You can download it at
http://www.dist-systems.bbn.com/tech/QuO/release/latest/index.html


Some of the changes / new features include
------------------------------------------
- enabled policy-based access control in the JacORB version of OODTE.
   Digital signatures still not working in JacORB version.
   Visibroker version of OODTE is now broken.
   [Franklin, Oct 3]

- changed release strucutre. The cvs/source directory tree and the release
   directory tree are now the same. We also just give out compiled tarballs
   for now.
   [Michael, Sep 15 2001]

- added --generate quogen flag to selectively generate qosket, adpater or both
   [Michael, Sep 16 2001]

- quogen cleanup: removed CSL and SDL parser and backend. In addition, cleaned
   out CDL parser. As a result, the source code size of quogen shrunk
significanly
   [Michael, Joe, Sep 14 2001]

- generation of native language (JAVA / C++) interfaces from qosket
   IDL interfaces added to quogen. In the past, people had to hand write both
   the IDL interface (Qosket.idl) plus a native language interface (Qosket.java).
   quogen now generates Qosket.java/Qosket.cpp from Qosket.idl automagically.
   [Michael, Sep 8 2001]

- added very simple downcasting support in ASL. The use of IDL types in ASL
   still has to be revisited.
   [Michael, Sep 11 2001]

- added -i2jpackage cmdline flag to make makefiles easier for jacorb.
   [Michael, Sep 10 2001]

- fixed bug in generation of C++ delegates, which caused coredumps in cause
   of undefined regions.
   [Michael, Sep 10 2001]

- cleanup up quogen: removed legacy CSL code that was not needed anymore.
   In addition, clean up code in general by removeing old cmdline flags.
   [Michael, Sep 10 2001]

- refactored C++ QuoKernel by taking out the quo namespace in all
   implementation classes. This makes the code more portables, and eliminates
   problems with cross-compiling from NT to VxWorks using the GreenHills
compiler.
   This changes was pervasive through quo/quo, quo/codegen, and all the C++
   qoskets and examples.
   [Michael, Sep 5 2001]

- implemented logging in C++ QuoKernel that allows to print out only data
   about region changes. Call kernelimpl->setDebug
(quo::QuoKernel::DEBUG_CONTRACT)
   to get that level of debugging.
   [Michael, Sep 5 2001]

Known limitations:
------------------
- quoRsvpOrb does NOT work on RedHat 7.1 yet. Partha Pal reported segfaults
   in rsvp agents on that specific platform.

QuO 3.0.6 got release today.

You can download it at
http://www.dist-systems.bbn.com/tech/QuO/release/latest/index.html

Changes since 3.0.5 include:
----------------------------

- quogen: started working on qosket composition.
   [Michael, Suzi]

- quogen: removed --contract flag.  A deprecation message is
   generated when it is used.
   [Suzi]

- quogen: added --delegate flag to be used to specify a name for the
   generated delegate file.
   [Suzi]

- quogen: automatically generating header files for C++ from qosket IDL.
   [Suzi]

- Our nightly builds are not compiling against vbj anymore.
   Although we assume our code still compiles with vbj, we no
   longer actively test against it. We use jacORB instead.
   [Michael]

- Fixed bug in cdl.yy that caused quogen to segfault on
   calls to syscond conditions in transitions. This bug was
   introduced by adding sequence of sysconds.
   [Michael, Suzi]
