    Documentation: Changes: 2.3.1
    
    
    
      
      General:
      
        - -log_info is now just -info; PetscLogInfo...() is now PetscInfo...()
- Added TOPS solver components. [requires CCA tools like babel]
- Added supported for IBM BGL with optimzed fortran kernels
- bin/petscarch is removed. Use can give any name to PETSC_ARCH. [if not - configure picks a default name]
- PetscMap is no longer a public PETSc object
Vec:
      
        - 
          Changed prototypes for VecMDotBegin(), VecMDotEnd(), VecMTDotBegin(),
          VecMTDotEnd() to confirm with PETSc prototype style
        
- ISColoringCreate() takes another argument
Mat:
      
        - MatScaleSystem() and MatUnscaleSystem() now take arguments b,x instead of x,b
- Added MatSeqAIJSetPreallocationCSR(), MatGetSubMatrixRaw()
- Added MatSolveTranspose() for superlu
- Added support for matrix types MATCSRPERM, MATCRL - for vector based machines.
- Added MatMatMult for seqdense
- Added MatRealPart, ImaginaryPart for AIJ, BAIJ, SBAIJ matrices
- Added MatGetRowUpperTriangular() to mpisbaij matrix
PC:
      
        - PCPrometheusSetCoordinates() changed to PCSetCoordinates()
- Moved src/ksp/pc/pcimpl.h to include/petsc/private/pcimpl.h
- PCPreSolve() and PCPostSolve() now consistently take arguments b,x before sometimes they took x,b
- PCXXXSetYYY() and -pc_xxx_yyyy are now changed to PCFactorSetYYY() and -pc_factor_yyyy for XXX LU, ILU, Cholesky, and ICC
KSP:
      
        - -ksp_view, -ksp_monitor now take an optional filename argument
- Added PetscLLAddPerm() to symbolic LU factorization
config/configure.py:
      
        - Changed --with-64-bit-ints to --with-64-bit-indices
- 
          config/configure.py now supports the arguments
          --with-precision=longdouble and --with-precision=int, these currently
          have limited functionality and certain things like binary IO does not
          work.
        
- 
          Option --LIBS=<extra libs> for some broken compilers that
          require that require extra system libraries to be linked with
        
- 
          Changed --with-fortran-kernels=<0,1> option to
          --with-fortran-kernels=<none,generic,bgl>
        
- Support --with-large-file-io=<bool> which indicates using files larger than 2GB
- 
          --with-f90-header, --with-f90-source options merged into a single
          option - for eg: --with-f90-interface=intel8
        
- 
          Added --with-is-color-value-type=<char,short>: char gives max
          of 256 colors, short gives max of 65536 colors
        
- 
          Configure always tries to build libraries with PIC [or equivalent
          flag] To disable this, use: --with-pic=0
        
- 
          Added --with-c-language-support for comiling PETSc with 'c' linkage
          - but with a c++ compiler.
        
- 
          ---download-mpich option now defaults to pm=gforker. To use mpd - use
          the additional option --download-mpich-pm=mpd
        
- 
          --with-timer option is added [if the user knows MPI_Wtime() is
          accurate/low-overhead on a machine - then use: --with-timer=mpi]
        
SNES:
      
        - -snes-view, -snes_monitor now take an optional filename argument
TS:
      
        - -ts_view, -ts_monitor now take an optional filename argument
DA:
      DMMG:
      
        - 
          Arguments to DMMGSetKSP() changed. Now the callback which forms the
          linear system matrix can optionally fill also an alternate matrix for
          the preconditioner.
        
SYS:
      
        - PetscViewerFileType changed to PetscFileMode
- PetscViewerSetFileType() changed to PetscViewerFileSetMode()
Fortran:
      
        - 
          remove the special libpetscfortran.a [fortran interface &
          c interface now go into the same library]
        
- 
          With some f90 compilers - PETSc datatypes [like PetscScalar,PetscInt]
          will use f90 KIND declaration - so if this code is in fixed form
          - there could be errors with lines exceeding 72 char limit
        
        - PLAPACK support added
- BLOPEX support added
- Updated Pvode interface to the newer Sundials package [configure option --download-sundials=1
- Added --download-mpe=1
- fblaslapack now has complete blas - as required by some external packages
