Blender 2.68 (64-bit)

What's new in this version:

MODELING:
General Improvements:
- Add option to remove all shape keys at once (r57246)
- Add curve falloff options to loop-cuts smooth option (r56562)
- Mirror tools now give feedback if verts can't be mirrored (r57245)
- Select shortest path now works for vertices - (Ctrl+RMB), (r57224)
- Lattice object now has an active element (r57320)
- Add Catmull-Rom spline as an option for lattice deform (r57733)
- Mesh normal re-calculation has been improved to give more reliable results with non manifold edges and work stably independent of orientation (r58088)
- The modifier stack has been optimized to eliminate unnecessary normal-calculations (r57145)
- Edge length display - keep within the view bounds so you can see edge length even when zoomed in (r57165)

Bridge Tool:
- The bridge tools has been rewritten to include support for more advanced features such as briding between loops of different size, the ability to bridge multiple loops at once, subdivision, surface blending and bridging face regions.

Grid Fill:
- The grid fill tool has been added which can fill in a grid from 2 connected edge loops.

Proportional Editing:
- Added support for x-mirror (r57616)
- Added the option to use Projected (2D) coordinates, has the advantage that you can deform areas without the twisting you normally get (r57608)

Snap to Symmetry:
- This editmesh tool lets you snap a meshes vertices to their mirrored neighbors with an adjustable tolerance (r57590)
- Useful when dealing with models which are close to being symmetrical but not enough for blender to recognize them when x-mirror option is enabled.
- Unlike the Symmetrize tool, this re-positions vertices to their mirrored locations rather than duplicating the mesh from one side to another.

Dissolve:
- Added the Face Split - When dissolving vertices into surrounding faces, you can often end up with very large, uneven ngons.
- The face split option limits dissolve to only use the corners of the faces connected to the vertex. (r56579)

Vertex Connect:
- When there are only 2 vertices select, a cut can now be made across unselected faces, a little like the knife tool, however this is limited to straight cuts across connected faces. (r57653)


CYCLES RENDERING:
Performance:
- Official Blender on Windows has become significantly faster, getting closer to performance on Linux and Mac OS X. Especially scenes with much geometry will benefit from the optimization, rendering often 30% faster. Linux and Mac OS X also benefit but more on the order of 10%.

CUDA:
- Support for NVidia Tesla K20, GTX Titan and GTX 780 graphics cards was added.
- CUDA performance is also improved, rendering 25% faster on various graphics cards and scenes.
- For users making own Blender builds: please upgrade to CUDA toolkit version 5.0 for best performance.
- Hair rendering is now available on the GPU as well. (r56600)

New Nodes:
- Wireframe node to get access to Mesh triangle wireframe data. (r56928)
- Toon BSDF with Diffuse and Glossy component is now available for Cartoon like effects. (r56980)
- Wavelength node to convert wavelength to RGB colors. (r57368)

Render Passes:
- Mist pass support was added, with start, depth and falloff control. This pass can be used in compositing to add fade out object that are further away, for example as a factor input for a Mix RGB node. If the pass is enabled in a render layer a Mist Pass panel will be shown in the world properties. (r57278)

Ray Visibility:
- Ray visibility is now supported for all light sources: lamps, emitting meshes and the world environment. Using these options it's possible to let light from these sources only selectively affect diffuse, glossy or transmission shaders.

Open Shading Language:
- Westin Sheen and Westin Backscatter closures were added for testing, useful for Cloth like effects. (r56900)

MOTION TRACKER:
Reconstructed scene scale ambiguity:
- Improved algorithms which deals with reconstructed scene scale ambiguity (r56632).
- This is done by scaling reconstructed scene in a way so reconstructed cameras variance is unity with a median in the 3D scene origin.
- Such approach helps in cases when different keyframe pair gives the same exact reconstruction from math point of view but some of which could be considered bad by artists because of bad scale.

Scene Orientation:
- Added a button to apply scale on scene solution (r56635).
- This is an alternative to using camera to scale the scene and it's expected to be better :solution because scaling camera leads to issues with z-buffer.
- Apply scale on scene reconstruction when applying scale on camera (r56764)
- This means when you've got reconstructed scene assigned to a 3D camera (via camera solver constraint) and applies scale on this camera from Ctrl-A menu, scale will be applied on the reconstructed scene and reset camera size to identity.
- This is very useful feature for scene orientation, when you'll just scale camera by S in the viewport to match bundles some points in the space, and then you'll easily make camera have identity scale (which is needed for nice working motion blur without loosing scale of bundles themselves.
- Behavior of apply scale for cameras without clip assigned to them does not change at all.

Refine Markers Position:
- Added Refine Markers Position operator (r56716).
- This operator will run a tracker from previous keyframe to current frame for all selected markers. Current markers positions are considering initial position guess which could be updated by a tracker for better match.

Automatic Keyframe Selection:
- Added an option to select keyframes used for initial reconstruction automatically (r57133). This option enables some fancy math algorithms which tries to find a keyframe pair with minimal reconstruction error and best scene scale guess.

Smaller improvements:
- Made bundles in 3D viewport have constant size (they're not affected by camera scale anymore) (r56633)
- Set scene frames operator for clip editor (r56664). This operator will set scene's start/end frames to match clip's start frame and footage duration.
- Marker placement for motion tracker by clicking on a desired location (r57138).
- Track Position node now could output absolute position of track at a given frame (r57414)

PHYSICS:
Particles:
- Use Modifier Stack - The Emission panel now has a Use Modifier Stack option to emit particles from the mesh with modifiers applied. Previously particles would only be emitted from faces that exist in the original mesh. Emitting from faces in the original mesh is mostly useful for hair, to preserve it through mesh editing operations and changing subdivision surfaces levels for viewport and rendering. For emitter particles it can be more useful to take all modifiers into account, but one must be careful to always use the same number of subdivision surface levels for this to work correctly. (r57005)
- Normal-Tangent Rotation - Normal-Tangent rotation mode added, so you can control the orientation around the normal based on the faces UV coordinates, allows for deformations that keep the particles facing the same way. (r58232)

Smoke:
- Full Sample - A new Full Sample" option was added to high resolution smoke panel. (r56665). When high resolution and full sample are enabled, the emitters now take the finer grid into account. Before the emitters where showing the blocks of the normal resolution grid even when the additional high resolution was enabled. This allows to use a lower base resolution for the simulation in many cases.
- Subframes - Emitters now have a "Subframes" option, for fast fast moving emitters. This allows for a smooth flow of smoke or fire even for emitters moving very fast. Previously, one puff of smoke was emitted for every frame, resulting in disjoint spots of smoke.

USABILITY:
User Interface:
- Display menu items key shortcuts in the button tooltips. (r57172).
- Drag-Toggle now allows all layers to be set at once. (r56748)
- Color picker now supports 3 digit hex colors like HTML, e.g. #123 becomes #112233. (r57135)
- Units, display 0.5mm rather than 500um, nicer when dealing with very small sizes but not microscopic (r57149)
- Double click now selects entire words (like on file path segments) (r57280)
- File-selector now maps back and forward history to back and forward buttons on a 5 button mouse. (r57285)
- For users without middle-mouse buttons, you can now use Circle and Border de-select by holding SHIFT. (r57577)
- Expanded control of enum properties in bitflag mode now follow other similar controls behavior (i.e. click only select one item, shift-click to (de)select several ones). See e.g. transform manipulators selectors, in the header of 3D views (r56706).
- Icon-only expanded enums where still using the label to compute their width, now they just take room needed by the icon (r57576).

Weight Paint:
- Reworked Weight Paint panel and added make it work in weight paint mode when vertex selection is enabled. (r57468)
- Weight tools such as limit-total, levels, clear - that operate on many groups can now select from active/deformed/non-deformed/all. (r57005)

Sequencer:
- Added a mask modifier for sequence strips (r56582).
- Fix naming of strips when adding a bunch of video files at once, previously all strips got the same name (from first file name), now each get a name matching it's underlying file (r57610).

Other:
- Auto indent for multi-line Python statements in the Python console. (r56558))
- Support for storing text styles in themes (r57275).
- Transformation Constraint now allows applies rotation offsets too (like for location) (r57309)
- 2D painting now supports texture masks and does masking more consistent with projection painting. (r56699)

Python Security:
- Auto-running Python scripts can now be controlled more securely.

Addons:
- New: Texture Atlas - Addon to bake shadow and lightmaps for an entire scene.
- New: Edit Linked Library - Quick editing of linked assets, opening the library file and returning to the original file.

Python API:
- Add popup menu to allow python scripts to show popups without having to define a menu class first (r57170)
- Add Mesh.calc_smooth_groups() function to calculate smooth groups from sharp edges (r57452)
