        - extended test applications
        - more samples


Release : 1.3
- Add an object descriptor that checks the connection :  od.checkConnection (project disconnect-1)
- Includes the POPC++ manual sources in Latex
- Comments added for Doxygen
- od.manual: a new object descriptor that simply prints the object launching command. (for debug)
- Add a od.url(host,arch) that can specify the architecture.
- Add std::string as a standard type. No marshalling funciton needs to be specified.
- Fix bug : Only list packed objects with -list/-listlong.

- For od.url() : You can now specify user@host{core}:port. (project DUO)
- Fix parser bugs :
    - "::" is accepted in class initialization
    - attributes can now be references
    - Add parser.lex and parser.y to the archive
- Fix bug with g++ compiler version 4.3.3
- Can compile for uc-linux. (project DUO)
- Change attribution of IP/URL for objects : use the ip of default gateway interface
- Rename all environment variables from PAROC_ to POPC_ (+ run autoreconf, automake)
- Check that an async method does not have an output in parser
- Added YYERROR_VERBOSE so the parser error are more explicit. (experimental)
- Create scripts to launch POPC with PBS (+ reedit existant scripts)
- Rename all scripts with popc- instead of paroc-
- Marshalling of vector/list is automatic + parser manages templates
- Improve exception handling
- Improve execution of POP-C++ as a batch job : PBS,SGE,LSF (+class batchmgr)
- Added the possibility to set the working directory of remote obj. By default it is equal to the current local working directory
- Modify the setter of paroc_exception
- Add two tests cases to the archives : demopopc and chat
- Fix a bug for POP-C++ with MPI
- POP-C++ is working on Mac
- POP-C++ tested on Kerrighed cluster


VERSION 1.2

- New combox and combox factory interface.
- Receive thread cancellation: close combox.
- broker main: Initialization is moved to paroc_broker::Initialize and paroc_broker_factory::Create.
- Compiler: "typedef struct { ...} X;" should use "X" as the type name (fix null pointer passed to buffer::Push().
- Allow mix "struct" and "class" declarations:
    struct X;
    class X // --> error in POP-C++ 1.1.
    {
        ....
    }

- Add PAROC_RSH environment to the runtime allowing the user to specify the "rsh" command to start the execution on a specific host.
- JobMgr::Exec: now the query of "jobmgr" can return a consequence of commands.

- paroc_setup: local command to submit jobs will be in front of  "webrun" in jobmgr.conf (avoid problem on starting the jobmgr service.

- Support pure virtual methods and pure class. Pure class can not create the object.
   parclass PureClass=0 {...}

- If no constructor is specified, add the default one so that the object can be created

- Compiler: add "#pragma interface/broker/object = newbaseclass" directive to define new base class for interface, broker and object

- paroc_interface: add paroc_Dispatch and paroc_Response methods. The compiler will call this method to send/recv requuests
- Detect reference loop and automatically free the object (ObjectMonitor)
- Add option "-constructor=id" to object executable to automatically construct default object
- AppCoreService will load add-on services (RegisterService/QueryService interfaces) specified in etc/appservice.conf

- Update the parser to parse the template types.
- Support for marshalling C++ STL types: vector, list and dequeue

- Update the parser to parse the template types.
- Support for marshalling C++ STL types: vector, list and dequeue


VERSION 1.1
- JobMgr: rename and change "fixnode" to "nodetype" of NodeInfo.
- JobMgr: All non static nodes will be remove from neighbor list upon forwarding failures (Forwarding method).
- POP-C++ parser: sequential class can now derive from a "struct" type. POP-C++ 1.0 will generate an error in this situation.
- Add "JobCoreService" parclass that provides the interface to create objects (CreateObject). JobMgr now derives from JobCoreService.

- New class "paroc_broker_factory" added to manage the list of brokers
- New compiler: on generating the broker code, popc also generates an object of type "paroc_broker_factory" for the corresponding broker. This object's constructor will be executed before the "main" which will register the current broker. Therefore, no need to declare the "@pack". Instead, just add the .ph (or .stub.o) file to the compiler to generate the object code.

- New intermediate C++ code: the compiler generate separate code for each constructor: allocate a resource and then call a method _paroc_Construct(...) to invoke the corresponding server constructor. This will allow to customize the object creation (MPI support).
- New option of compiler to specify the start file for object. Option: "-object=<type>".
- New paroc_interface::LocalExec method: allow to create multiple objects.

- Fix potential bug when a connection is closed on the receiving thread but it is possibly still used in the serving thread: Add "Clone" method to the paroc_combox to clone the combox before passing it to the serving thread.

- Startup script: the temp key file now contains the user name to allow different users to start SXXparoc* on the same system.

- MPI support: sub dir "mpi" added to allow users to startMPI processes and attach them to parallel objects. Require: include "paroc_mpi.h" and add "-object=mpi" on generating object executables.
