                       MPI 1.2 C++ Bindings

Version History
===============

Version 1.0.6
Unreleased
================

- Fixed problem with the copy constructor of Intracomm, Cartcomm,
  Graphcomm when profiling such that the internal pmpi_comm was
  initialized properly.
- Removed a bunch of confusing #if 0 blocks from various header files
  (mostly related to communicators and errorhandlers).  For the
  record: doing the Right Thing with friend functions (rather than
  uncodumented public functions) is not always portable.  Before you
  ask -- it has to do with the C callback mechanism in MPI -- since
  we're implemented on top of the C bindings, we have to use the C
  callback mechanism and intercept all the calls, then lookup which
  function to call.  Ugh!!
- Added check in contrib/examples/topology.cc to ensure that it is run
  with 4 ranks.
- Added proper cleanup of MPI::ERRORS_THROW_EXCEPTIONS in
  MPI::Finalize() to prevent a memory leak.
- Added a copy constructor to the MPI::Exception class; since it
  contains a (char*) (for efficiency), the default copy constructor
  would cause a duplicate delete[] upon destruction.
- Cleaned up various bugs and memory leaks in the test suite.
- Now support MPI_GET_VERSION if the underlying MPI has it.
- Removed an errant <iostream.h> from <mpi++.h> (and added it back to
  the .cc files that needed it; oops). 
- Use MPI_STATUS_IGNORE if the underlying MPI has it.
- Fixed minor memory leak in Datatype::Create_struct; thanks to Maria
  Barnes.  
- Removed use of NULL in comm.cc.
- Now installing header files into $(pkgincludedir), and symlinking
  mpi++.h back into $(includedir).  Changed the #include statements in
  mpi++.h (and others) to be <mpi2c++/foo.h>.
- Changed the examples to compile with $(bindir)/balky, hence you have
  to do a "make install" first.
- Added 'extern "C"' before all intercept routines.
- Fixed a buch of incompatabilities with MPICH 1.2.1 (#%#@%@#%!!).
- Save the CXXFLAGS before we call AC_PROG_CXX (lest they be destroyed
  or otherwise modified automatically by autoconf)
- Added automake support to get all the rights and privlidges granted
  therein (get that VPATH stuff right this time)


Version 1.0.5
10 November 1999
================

- Removed some small memory leaks, both in the test suite and in
  libmpi++.a.
- Renamed some .h files to not conflict with STL header file names.
- Prepended all #define macros with MPI2CPP or _MPIPP so that we have
  our own namespace and won't conflict with anyone else.
- Fixed some random potential seg faults in the test suite.  Thanks to
  Andy Isaacson at SGI for finding these.
- Patched up configure.in to use more modern tests (to reflect
  better diagnostics, more C++ compiler checks, and updated to 
  handle newer implementations of MPI).
- Split libmpi++.a into 2 files: intercepts.cc and mpi++.cc.  Required
  for some compilers/linkers, because if you -lmpi++, all the global
  constants in mpi++.cc will force the linker to pull all of mpi++.o
  out.  There was a reference in it to cerr, so if you linked with a C
  compiler, cerr was not found.  Splitting into 2 files solved this.


Version 1.0.4
Internal release
================

- Fixed #define naming conflicts with OOMPI (since this package
  inherited ./configure.in from OOMPI).  Problematic because this
  package is included in MPICH, (soon) LAM, and other vendor MPI 
  packages.
- Set LAM ./configure tests to figure out which LAM it is using (6.1
  or 6.2 or 6.3)
- Changed ./configure to not generate a config.cache
- Removed skip flags for HP 1.03 and HP 1.05 (they didn't do anything)
- Fixed bug inherited from OOMPI in Makefile.in with extra ` character
  when grepping for version number


Version 1.0.3
2 February 1999
===============

- Tested and passed with several more compilers
- Updated for new versions of MPICH (1.1.2) and LAM (6.2)
- Revealed problem with HP aCC compiler
- Fixed bug in use of conversion operators, which affected 
   the create_struct test among others. The problem showed
   up only with the IBM xlC compiler.


Version 1.0.1
4 June 1998
===============

- Temporarily removed KCC from list of supported compilers
  due to a failure in test suite with Isend Irecv
- Replace usage of bool with MPI2CPP_BOOL_T for pesky compilers
  and STL (or other libraries that define bool).
- Fixed a bug with the MPI to PMPI object conversion methods
- Removed the last 92 byte memory leak from group.cc in the test_suite.


Version 1.0
8 December 1997
===============
