Mantaflow Release Notes
------------------------

version 0.11 (Jul 2017) 
-------------------------
- coupling with the machine learning framework tensorflow, including a few examples of coupling mantaflow with neural networks (in the "tensorflow" directory)
- closely related: numpy arrays are now a native datatype for mantaflow kernels and plugins (enable with -DNUMPY=1 in cmake)
- support for surface tension simulations (look for the surfTens option in the pressure solver)
- a simple viscosity solve for more physical scene setups (e.g., check out the lid-driven-cavity scene in scenes/lidDrivenCavity.py) 
- smaller bugfixes

version 0.10 (Mar 2017) 
-------------------------
- new, fast multigrid solver (thanks to Florian)
- flow guiding with convex optimization (thanks to Tiffany and Marie-Lena)
- support for 4d grids and vectors
- long long int type introduced for huge grids and particle systems
- additional display modes (projection, shaded projection)
- and, as usual, quite a few bugfixes and tweaks

version 0.9 (May 2016) 
-------------------------
- this release includes algorithms from two recent papers: an
  appraoch for narrow band FLIP simulations, and for surface turbulence
  (Ferstl et. al Eurographics 2016, and Mercier et al. SIGGRAPH Asia 2015)
- there's new cmake switch to compile without python (NOPYTHON), this makes
  it easier to include mantaflow as a library
- various cleanup fixes, e.g., a mantaMsg function was added for 
  output under windows (use it instead of "print" in the python scenes)


version 0.8 (Oct 2015) 
-------------------------
- improved and more stable out- and in-flow handling
- second order wall boundary conditions (see flip05_secOrderBnd.py example)
- improvements for using MS Visual Studio (better IntelliSense parsing)
- easier handling of adaptive time steps (moved to FluidSolver class)
- Improved surface reconstruction for FLIP simulations
- UI improvements, new drawing modes, and faster re-draw
- more tests, reliable double precision testing, plus a visual test mode 

version 0.7 (Aug 2014) 
-------------------------
- added generic set of operators for grids and particle data fields
- parallelized surface creation, and fixes for free surface and obstacle boundary conditions
- extended test system
- complete rewrite and cleanup of preprocessor, support for templated and overloaded operators
- re-organized UI keyboard shortcuts
- support for qt5
- zlib inclusion to reduce compilation issues
