Use the primoridal Helium abundance to compute the Hydrogen mass fraction. Optionally read the temperature transition from the YAML parameter file.

Read the minimally allowed temperature from the parameter file and convert it to a minimal internal energy per unit mass.

Updated the way we converge towards the smoothing length. We now use a Newton-Raphson scheme. This applies to the Gadget-2 scheme.

Added a maximal smoothing length that can be used to prevent particles from becoming too big in vacuum cases near the box edges. Will break the accuracy of the hydrodynamic scheme but is necessary in some situations.

Properties of the self-gravity scheme are now read from the YAML file. They are printed to stdout and to snapshots.

Move more code into partition.c and remove param.h.

The Makefile now generates a file containing the git revision hash key of the project. A temporary file is used for the distributed tarball versions.

First version of parallel output using parallel HDF5. The structure of the output file is unchanged.        
Each MPI task writes its particles to the same file in parallel. 
Attributes are unchanged. 
Chunking and compression to reduce file size still has to be investigated.

First iteration of the "improved SPH" implementation. The code now uses a (Rosswog et al, 2000) viscosity term with a (Balsara , 1995) switch and the parameters given by (Price, 2004). 
Thermal conductivity is implemented following (Price, 2008) without the switch.
Both scalar and vectorized versions have been implemented. 
The code now gives a much better answer on the Sod shock. More testing will be required on more advanced tests to tune the parameters.

When "LEGACY_GADGET2_SPH" is defined, the code defaults to the old gadget-2 version of SPH.

massive refactoring, added spearate scheduler, new scheduling policy based on task rank, should expand to task weight some time soon.
