 We are pleased to announce the release of the PETSc 2.3.3 parallel
 software libraries for the implicit solution of PDEs and related
 problems.

 There are a couple of MAJOR interface changes, listed at
 http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/changes/233.html
 please check these changes before compiling your codes. In particular
 the calling sequence for VecScatterBegin/End() now takes the scatter context
 as the first argument not the last.

 You can download from
 http://www-unix.mcs.anl.gov/petsc/petsc-as/download/index.html and
 and the installataion instructions are at
 http://www-unix.mcs.anl.gov/petsc/petsc-as/documentation/installation.html

 As always, please send bug reports, questions, and requests for new
 features to petsc-maint at mcs.anl.gov

 Thanks for your continued support.

 The PETSc developers,
 Satish,  Lisandro, Matt, Victor, Barry and Hong
