Breaks backward compatibility of FEMContext.
* Intel 14.0 Compatibility.
* Streamlined checkpoint/restart capability for ephemeral usage.
* new --disable-warnings option.
* Added heterogeneous Dirichlet adjoint constraints.
* Added edge Dirichlet constraints.
* Improved support for non-32-bit IDs.
* PETSc 3.5 support.

* Memory optimizations for Metis/Parmetis partitioning auxiliary
data structures.

0.9.1 -> 0.9.2
* PETSc 3.4 support
* PETSc BAIJ matrix support for blocked matrices
* opt-in for this with './configure --enable-blocked-storage ...'
* may cause issues with preallocation in Reduced Basis code -
see http://sourceforge.net/mailarchive/forum.php?thread_name=B4613A7D-0033-43C7-A9DF-5A801217A097%40nasa.gov&forum_name=libmesh-devel

* Assorted bugfixes:
* for nonstandard index sizes
0.9.0 -> 0.9.1
* 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

* 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
0.8.0 -> 0.9.0
* automake build system
libMesh-specific implementation features:
source and header files must be listed explicitly.
When adding a header file,
1.) svn add the file
2.) cd include ; ./rebuild_include_HEADERS.sh
3.) cd include/libmesh ; ./rebuild_makefile.sh
When adding a soure file,
1.) svn add the file
2.) cd src ; ./rebuild_libmesh_la_SOURCES.sh
General notes:
o make install && make installcheck
installs the built library & performs sanity checking
o make distcheck
packages up a tarball and tests it for self-sufficiency.
always do this when modifying the build system.
o for more information, view the README and INSTALL files.
* VariableGroups DofObject storage optimization for the common
case of multiple Variables of the same type within a System.
Note this changes the default variable ordering within a
System - the old format is available via System::identify_variable_groups()
* TecplotIO binary format updated to support v11.2 features where
available. This includes encoding the solution time into output files,
writing each libMesh subdomain to a separate Tecplot zone, and support
for 1D Tecplot binary files.
* ./configure'able support for identifier types. Defaults:
id size (boundaries)............. : 2 bytes
id size (dofs)................... : 4 bytes
id size (processors)............. : 2 bytes
id size (subdomains)............. : 2 bytes
* Reduced memory footprint for Node objects.
* Fix for using specified preconditioners with adaptivity and PETSc-3.3.
* New Examples:
o fem_system_ex2: Nonlinear elasticity, courtesy Robert Weidlich.
o adjoints_ex5: Unsteady Adjoints.
o miscellaneous_ex8: meshfree, inverse distance interpolation.
