- Normalize strand coordinates over the length of the strand, not
  cut off when with e.g. length texture control.
- Weight paint and particle mode x-mirror now works with deformation
  and shape keys active.
- X-ray is now disabled in particle mode, messed up depth tests.

- Added texture control for child particle roughness.
- Fix some use of uninitialized variables in particle texture code.

=========

- Texture orco coordinates for particles are now actual orcos instead
  of just the vertex positions, which means they are the same under
  deformations and the same as the ones on the mesh.
- Particle distribution now uses these orcos to get consistent
  distributions independent of deformation.
- This required changing the way orco's are computed for meshes. Now
  instead of generating an orco derivedmesh separately, the derivedmesh
  is generated alongside the regular one and stored in an orco custom
  data layer.

- Fix crash in particle transform with the particle system not editable.
- Particle child distribution and caching is now multithreaded.
- Child particles now have a separate Render Amount next to the existing
  Amount. The render amount particles are now only distributed and cached
  at render time, which should make editing with child particles faster.

- Two new options for diffuse strand shading:
	- Surface Diffuse: computes the strand normal taking the normal at
	  the surface into account.
	- Blending Distance: the distance in Blender units over which to
	  blend in the normal at the surface.
- Special strand rendering for more memory efficient and faster hair and
  grass. This is a work in progress, and has a number of known issues,
  don't report bugs to me for this feature yet.

=========

- Fix crash with the cut tool and child particle drawing.
- Make the "Col" option to use material colors work for
  the path/hair visualisation type.

=========

- Fix for bug #7840: adding particle system to nurbs, curves crashes.
  Now simply doesn't allow to add a particle system to a non-mesh
  object, the current code does not support it.
- Fix for bug #7834: deleting vertices of an object with a particle
  system crashes. Fixed by disabling particle display for objects in
  editmode.
- Fix for the particle add brush on subsurfed objects.

=========

Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:

- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.

.. and lots of other things, some more info is here:

http://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc

The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.

Point Cache
===========

The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.

See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint

Documentation
=============

These new features still need good docs for the release logs, help
for this is appreciated.
