ChangeLog

-nbody 1.96
	- Added cutoff NFW and Cored profiles
	- Added a single component King model
	- Updated softening length to use different values depending on the types of the particles in the
	interaction
	- Added a fallback to checkpointing that will use standard input/output fuctions when memory mapping is not available
	- Removed references to unused screensaver code
	- Fixed a bug that would change behavior on ARM systems. Linux aarch64 is now officially supported
	- Added softening length test
	- Removed context test
	- Updated tests for new code (bar tests fail)
	- Various code cleanup/ fix compile warnings

-nbody 1.95
	- Fixed bug that would miscalculate forces on the MW from the LMC and sometimes result in memory leaks

-nbody 1.94
	- Fixed bugs in for_developers.lua so that preset parameters are set if not specified when using manual bodies
	- Changing set_vars in nbody_mixeddwarf.c so that the NFW portion of the cored profile is the same as the NFW profile
	- Changing KL divergence in mixeddwarf_test.c for correct distribution comparison
	- Changing parameter set for mixeddwarf_test.c to reduce the number of particles needed for stable dwarf
	- Updated LMC dynamical friction
	- Added support for different LMC models
	- Added SphericalNFWerkalHalo halo type
	- Fixed mass calculation in nbody_isotropic.c
	- Added momentum information to HistogramParams, updated nbody_histogram.c to read in and print momentum info
	- Some information passed through HistogramParams (momentum, EMD range) can now be passed through lua
	- New Likelihood compoenent for momentum
	- Fixed a bug where checkpoints would not store best likelihood info
	- Updated nbody flags for easier control of which likelihood components to use in compare only
	- Reduced the chance that randomPotential will create a negative density, leading to crash (this is why checkpoint test sometimes fail)
	- Softening length calculation updated to be based off dwarf model
	- Added tests for new features, updated model tests to work for new versions and test new softening length, reduced number of model tests
	- Removed unused library: libelf
	- Fixed an issue that would cause segfaults on some runs with a specified baryon number
	- Fixed or suppressed various compiler warnings

-nbody 1.93
	- Temporary fix for compiling windows binary with OpenCL(works for milkyway-old but might not work for all linux manchines)

-nbody 1.92
	- Fixed likelihood calculation to correctly calculate with pmra

-nbody 1.91
	- Cored profile added to dwarf potentials 
	- Proper Motions can now be calculated for every particle at every timestep 
	- Added option to average over data in a number of bins in the simulated histogram for likelihood calculation
	- Mass of the LMC is now a optimizable paramter 
	- Output format is either Simple Format or the Full Format 
	- Initial bodies file can now be outputed  

nbody 1.90
	- Velocity distribution function now separate for baryons and dark matter
	- Number of baryons can be set directly now and not automatically set as half the total number of bodies (set to half automatically if not specified in lua file) 
	- Added new stability test that uses  Kullback–Leibler (KL) divergence to compare the simulation probability density distribution to the theoretical probability distribution function

nbody 1.85:
	- now declares binary version being used at runtime in terminal
	- all workunits have timesteps corrected, not just those with
	  versions < 0.80 (side effect of the above, see nbody_lua_nbodyctx.c)
	- Lots of additions and changes that weren't properly tracked. 
	  For example, autodiff was added in 1.84, and then removed
	  for this version. LMC was added in 1.82 and has had numerous 
	  bug fixes since then. I don't know all the changes, so I
	  can't list them, but we need to be better about this from now
	  on. -Tom
