So are there any more outstanding issues for the 0.9.1 release?  Just trying to get an idea of when it'll be available.  We are going to deploy this version to our users instead of wherever HEAD is at.

Testing before we make a 0.9.1 final release would be appreciated.
Please report any problems to or at

Apologies to all for the 200% increase in tarball size.  libMesh now
includes more and much larger 3rd party packages in the contrib/
directory.  If there's any demand, I may put together "libmesh-lite"
and "libmesh-everything" versions of our tarballs for the final 0.9.1
release, to provide a smaller option for users who either already have
local copies of or don't want to use all the optional I/O packages.

Changes in 0.9.1 include:

   * Multi-communicator-capable objects
     * Communicator-using ParallelObject subclasses can be initialized
       with arbitrary MPI communicators, independent of the
       communicator used to init libMesh or the communicators used by
       other non-interacting objects
     * No internal library code still uses CommWorld communicators
     * CommWorld and global Parallel:: methods can be disabled via
       configure --disable-default-comm-world, breaking backwards
       compatibility, to facilitate compile-time checking of
       libMesh-based codes for compatibility with multi-communicator
       * These methods will be disabled by default in future versions,
         but configure --enable-default-comm-world will work for the
         next few releases
   * Additional specializations for Parallel:: communication methods
   * New SolutionTransfer infrastructure, implementations, examples
   * Singleton framework added
   * Complex-valued libMesh builds can new read real-valued restarts
   * Interface to and contrib copy of Eigen linear algebra package
   * Interface to and contrib copy of newer Nemesis/ExodusII/NetCDF
   * build Tecplot binary I/O library from source,
     * old behavior can be restored via --disable-tecio
     * --enable-tecplot
   * Assorted bugfixes:
     * UnsteadySolver is now more robust inside AMR loops
     * Preconditioner setup is more robust with AMR
     * Fixes in Trilinos and SLEPc package interfaces
     * Fix for multithreaded QoI derivative assembly
     * Fixes for compiler and 3rd party library compatibility
   * Clarifications, updates to API documentation
