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.
