------------------ Portable, Extensible Toolkit for Scientific  
Computation (PETSc)--------------------

We are pleased to announce the release of PETSc 3.0; parallel software  
libraries for the
implicit solution of PDEs and related problems involving sparse  
matrices.

Major improvements include
*  PETSc modules and interface definitions for use from Fortran 90
* A much improved interface for using external direct solver packages  
include: MUMPS,
   SuperLU_DIST, PLAPACK and Spooles
* A brand new Python interface (developed by Lisandro Dalcin)
* An implementation of the Yand and Brent variant of Bi-CG-stab that  
requires a single
   parallel synchronization step per iteration
* Preliminary support for unstructured meshes. The Sieve interfaces  
allows creation,
   manipulation, and output of unstructured meshes in any dimension
   (developed by Matt Knepley and Dmitry Karpeev)
