[SciPy-user] Parallel linear solver.

Yes, there will be a new release of PETSc soon (I just asked one fo the
developers), but they don't know exactly how long it will be. The  2.3.3
release of PETSc is still current.  They use patches for a lot of their
small changes.  For example, just a two months ago or so, I downloaded a
version that was 2.3.3-p8.  The current patched version is 2.3.3-p13.  It is
still very active, and in my opinion, major releases are not a good thing,
because it may end up affecting your code.  Actually, I think this is
probably why you asked (so you could wait until a new release so you
wouldn't have to worry about code changes for a while).

Hope this help,
Frank
