[petsc-dev] Release of petsc-3.4

[Barry Smith]

We are pleased to announce the release of PETSc version 3.4 at http://www.mcs.anl.gov/petsc

  The major changes and updates can be found at 

http://www.mcs.anl.gov/petsc/petsc/documentation/changes/34.html

  We recommend upgrading to PETSc 3.4 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 include a system for managing unstructured grids with PDE solvers in DMPlex. 
Capability and performance improvements to the algebraic multigrid preconditioners PCGAMG, many
new nonlinear solvers in SNES, many improvements to the ODE solvers in TS including the new
TSEIMEX, and support for parallel dense linear algebra using  MatElemental.  The library also 
has better encapsulation and better control of symbols.

   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.
