Version 8.0 of Trilinos has been released:

     http://trilinos.sandia.gov

Trilinos is a collection of scientific, object-oriented solver  
packages.  These packages cover linear algebra services,  
preconditioners, linear solvers, nonlinear solvers, eigensolvers, and  
a wide range of related utilities.  Trilinos supports serial and  
parallel architectures, as well as dense or sparse problem  
formulations.  Included in Trilinos release 8.0 is PyTrilinos version  
4.0,

     http://trilinos.sandia.gov/packages/pytrilinos

a set of python interfaces to selected Trilinos packages.  New in  
version 4.0 of PyTrilinos is an interface to Anasazi, the eigensolver  
package, and the re-enabling of NOX, the nonlinear solver package.

The primary Trilinos linear algebra services package is Epetra, which  
provides Vector and MultiVector classes, as well as hierarchies of  
operator, communicator and domain decomposition classes.  The  
PyTrilinos interface to Epetra has been designed with a high degree  
of compatibility with numpy, with the hope of complementing the SciPy  
development efforts.
