Nils Thuerey 3bea663ffa - bugfixes 
#4742 exported normals are now correct
  #4821 & 4956 for complex movements in/outflows can now also
  use the animated mesh option
- new features
  * isosurface subdivision: directly
    creates a finer surface mesh from the simulation data.
    this increases simulation time and harddisk usage, though, so
    be careful - usually values of 2-4 should be enough.
  * fluidsim particles: extended model for particle
    simulation and generation. When isosurface subdivision is enabled,
    the particles are now included in the surface generation,
    giving a better impression of a single connected surface.
    Note - the particles are only included in the final surface
    mesh, so the preview surface shows none of the particle
    effects.
  * particle loading: different types of particles can now be selected for
    display: drops, floats and tracers. This is a bit obsolete
    due to the extensions mentioned above, but might still be useful.
    Floats are just particles floating on the fluid surface, could
    be used for e.g. foam.
  * moving objects impact factor: this is another tweaking option,
    as the handling of moving objects is still not conserving
    mass. setting this to zero simply deletes the fluid, 1 is
    the default, while larger values cause a stronger
    impact. For tweaking the simulation: if fluid disappears, try
    increasing this value, and if too much is appearing reduce it.
    You can even use negative values for some strange results :)
- more code cleanup, e.g. removed config file writing in fluidsim.c,
  added additional safety checks for particles & fluidsim domains (these
  currently dont work together). I also removed the "build particles"
  debug message in effects.c (seemed to be unnecessary?).

Some more info on the new features:
Here are two test animations showing the difference between
using the particle generation with isosurface subdivision.
This is how it would look with the old solver version:
http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid6_fl6manc4_1noparts.mpg
and this with the new one:
http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid6_fl6manc4_2wparts.mpg
Both simulations use a resolution of 64, however, the version with particles
takes significantly longer (almost twice as long).
The .blend file for a similar setup can be found here:
http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid6_testmanc4.blend
(Minor Tips for this file: dont enable subdivions of characters until rendering,
thus leave off for simulation, as it uses the rendering settings! For making
nice pictures switch on subdivion, and OSA.)

And here's a picture of old vs. new (for webpage or so):
