[petsc-announce] Release of PETSc 3.5

[Barry Smith]

We are pleased to announce the release of PETSc version 3.5 at http://www.mcs.anl.gov/petsc
  
The major changes and updates can be found at 

     http://www.mcs.anl.gov/petsc/documentation/changes/35.html

We recommend upgrading to PETSc 3.5 immediately. As always please report problems to 
petsc-maint at mcs.anl.gov and ask questions at petsc-users at mcs.anl.gov

Notable new features/changes include 
     
     * KSPSetOperators(), SNESSetJacobian(), TSSetRHSJacobian(), and TSSetIJacobian()
       no longer have a MatStructure argument, PETSc automatically tracks if the matrix structure has changed.
       The Mat * arguments in these functions have also been changed to Mat
     * the Tao scalable optimization software package is now included directly in the PETSc releases
     * added DMNETWORK for simulations/computation on graphs, networks, and circuits
     * DMDA requires much less memory usage in most situations
     * --download-suitesparse  now supports all solvers in suitesparse and replaces —download-umfpack and —download-cholmod
     * added support for MKL’s Pardiso with ./configure --with-mkl_pardiso-dir and -pc_factor_mat_solver_package mkl_pardiso
     * compiles of PETSc source now, by default, use GNU Make instead of Cmake and are more robust
     * many addition/improvements to DMPlex unstructured mesh management
     * there is no longer separate ISLocalToGlobalMappingBlock objects, instead the ISLocalToGlobalMapping 
       contains a block size

  If you are using the threaded version of PETSc or PETSc on GPUs you should continue to work with
petsc-dev since this code is too much in flux to be contained in a release.
