libMesh version 0.9.1 is now officially available:
http://sourceforge.net/projects/libmesh/files/libmesh/libmesh-0.9.1/
Please report any problems to libmesh-us...@sourceforge.net or at
https://github.com/libMesh/libmesh/issues
Changes from 0.9.1-rc1 are limited to mesh stitching behavior.
Changes from 0.9.0 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
usage.
* 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
