=========
Bugfix for crash with disabling the particles system and saving/loading
files, the way it detected if the mesh had changed could not work correct.
- new option for Local Constraint Ipos did not set user counter in
Ipo at file reading, causing data to get lost (not saved).
- Driver feature: the channels "Loc X Y Z" now also use the result
of constraints, but transformed back into local space, as if it
was action X Y Z. Nice stuff for those who understand this...
it means you can drive something with a bone that has constraints.
modifier.c, BKE_modifier.h - flag for modifiers to say they use pointcache, also new func modifiers_usesPointCache
renamed //pointcache to //blendcache_blendfilename so blendfiles in the same dir dont conflict, and other to show this dir isnt limited to pointcache only (nodes way want to use this)
wizard_curve2tree.py - better defaults for pretty tree's
Fixes for bugs in #7833
- Hair softbody cache was reset on rendering.
- When Alt-a playback is synced to audio frames are skipped. This caused dynamics caching to go crazy. Now the first loop of playback goes through all frames if there are non cached dynamic systems.
Invalid point caches weren't cleared when new systems were created. This caused messed up shapes when softbody was added.
==========
- Added a Mute button for shape keys, useful for debugging the influence
of driven shape keys.
- Bugfix for the shape keys relative to others keys, was hanging in
an eternal loop when deleting the other key.
=============
A new "Selected to Active" option in the Bake panel, to (typically) bake
a high poly object onto a low poly object. Code based on patch #7339 by
Frank Richter (Crystal Space developer), thanks!.
Normal Mapping
==============
Camera, World, Object and Tangent space is now supported for baking, and
for material textures. The "NMap TS" setting is replaced with a dropdown
of the four choices in the image texture buttons.
http://www.blender.org/development/current-projects/changes-since-244/render-baking/
in EditButtons, panel "Links and Materials", there's now a browse button
to directly assign a material to selected faces. It does:
- check if material was already in one of the 'slots' of the object
- if so, then use this as index to assign
- if not, then add a new slot, and assign the new index
-> Constraint Influence Ipo now can be local, linked to constraint itself
You enable this in the IpoWindow header, with the Action icon to the left
of the Ipo Type menu. The button tooltips give the clue as well.
Tech note: the Ipo now can get directly linked to a constraint, and is
being called during regular pose constraint solving.
Actions (and drivers in actions) are being calculated *before* pose
constraint solving. Result of actions then is written in bones, which
then solves the entire pose.
This means you can have a driver on both the constraint, as on the action
channel for the constraint! Not that I'm going to debug that easily :)
Additional fix: Joshua added a copy/paste IpoCurve feature, but he broke
the functionality to be able to paste in an empty ipo channel. That now
works again
=========
- 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.
=========
- Fix for bug #7832: boids physics crashed.
- Bugfix for child particles not getting orco texture coords.
- Allow smaller strand sizes in blender units.
- Fix for a common but harmless uninitialized value warning in
valgrind, in the event queue.
=========
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_Rewritehttp://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.
NLA Window, Strip blending mode "Add" didn't work at all.
It was using very bad quaternion addition. Replaced with proper code.
For devs; new is the function QuatMulFac(quat, factor) which allows to
multiply a rotation with a value (make it rotate more or less)
Patch by: Matt Ebb (broken)
Currently in Blender, NLA action modifiers can work in very wacky and mysterious ways.
If an action is being modified with a path deform, when it reaches the end of that strip, it will snap back to the original un-modified location, regardless of whether the strip 'Hold' option is on. It's very frustrating to work with, and causes all sorts of problems - if you use a path to make a character walk from point A to point B, you generally want him to stay at point B, and not jump somewhere completely different, just because the strip ended.
This patch fixes this behaviour, and makes it much more sensible and predictable. There is a chance that this will break old files that were reliant on the old broken behaviour though, but I think it's definitely worthwhile to fix this problem.
Check the demo file in Blender 2.45 vs one with this patch applied - you can see the difference in behaviour.

Relative shapekeys now allow to define the Shape it is relative to!
(It used to be relative with respect to the first key, which is still
default).
The reason for this feature is that keys don't always add together
well when they're all derived from the same base shape. A clear
example is hard to make... will wait for someone posting it. :)
- error fix: overall weight group value was used inverted
- added "Inv" button to make weight group work inverted
- added bigger, more clear Multi Modifier button
This allows to mix between the result of 2 modifiers, with both
using the same input state. This is useful for having a mesh deform
and armature deform working together.
However! This functionality could have been presented better...
this is actually Node editor stuff!
Now it works by adding a "MM" button, next to the "overall vgroup"
option. If MM is pressed, the input of this modifier is the same as
the input of the previous modifier.
Only the armature modifier has this option now...
This option sets the relative scaling factor to the amount set in the
scene "100%/75%/50%/25%" buttons. It's useful when you've got a fixed
background image, and want to do preview renders at a lesser
percentage, so you don't have to go and change the scale node each
time you change the %.
Also removed unnecessary use of a global from texture node.
Support for using the axes of a different object as the line of mirror
symmetry for a mirror modifier. As a nice consequence, this allows
"clipping" to arbitrary planes in editmode.
A fun example of using a couple of mirror modifiers and an array
modifier to easily make a nice flower type model is here:

Patch by: Roland Hess (harkyman)
For example, a constraint can be sub-targeted at the 50% (or 31.2% or 85% etc.) point of its target bone, giving you enormous rigging flexibility and removing the need for complex contraptions to do such things as:
- A bone whose base slides only between to points on a rig (CopyLoc with a variable, animated subtarget point)
- Bones that attach to multiple points along another bone (CopyLocs, each with a different head/tail percentage)
- Bones that need to stretch to a point midway between specific spots on two other bones (old way: too crazy to mention; new way: stretch bone between points on end bones, then another stretch to the midpoint of the first stretch)
It is only used for the constraint types for which it is relevant: CopyLoc, TrackTo, StretchTo and MinMax, TrackTo, and Floor.
Notes:
- This is accessed by the Head/Tail number-slider.
- This value can be animated per constraint
- The old "Copy Bone Tail" option for the CopyLoc constraint has been automatically converted to 1.0 Head/Bone values for the affected constraints
- In the code, this value is in the bConstraint struct, so it is available for all constraints, even though only a few implement it.
====================
Dynamic binding support. This means that the mesh can move _within_
the cage and still deform correct. If the mesh goes out of the cage,
don't expect correct result. Must be enabled with the 'Dynamic'
option, because it is slower and consumes more memory.
This is useful to use e.g. the cage mesh for main deformations and
still have shape keys for facial deformation working.
* made stamp filename optional
* renamed weightpaint "Filter" to "Blur"
* made the defailt weightpaint opacity 1.0 rather then 0.2 so when you select 1.0 weight you can paint it with without multiple clicks.
B-bones didn't work well with non-uniform scaling applied to them.
The code to solve this is not too pretty, but don't know how to do
it simpler, and at least it makes that stretchy spine work.
