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)

What's new in this version:

Freestyle Line Rendering Engine:
- Freestyle is a new non-photorealistic (NPR) rendering engine integrated into Blender. Originally developed as a stand-alone program in an academic research project, Freestyle provides artists with a new tool set for generating 2D line drawing out of a given 3D scene prepared with Blender. Generated lines can be stylized by a variety of stylization options for tweaking line color, alpha transparency, line thickness, and line geometry. The resulting line art can be combined with other render components (e.g., render passes from the Blender Internal renderer and Cycles) through render layers and the compositor. Examples of Freestyle use cases include cartoon rendering, architectural visualization, technical drawing, blue prints, and computer-generated sketches. Freestyle expands Blender's rendering capabilities on the basis of geometry-based visualization solutions specifically geared to 2D-like computer graphics.

Paint System Improvements:
- The stroke system and brush texture access has been unified and as a result there are many more tools now shared across paint modes. Brush angle control, better brush overlays, separate texture control for alpha and a brand new stencil mapping mode with direct mouse control have been implemented. Many improvements and bug fixes have also been made.

Cycles Rendering:
- A Subsurface Scattering shader is now available, to create materials such as Wax, Marble or Skin. Minimum pixel width was added to hair rendering and several performance improvements have been made, to render scenes without hair or motion blur faster. The OSL shading system received performance improvements as well.

Motion Tracker:
- Camera and object motion solver motion are much more accurate and faster because the Ceres library is used now for the bundle adjustment step. In addition the tripod solver is finally fixed and has become usable for longer footage. Smaller fixes were done as well.

Compositing Nodes:
- Added border for compositor viewer node, which restricts what is to be composited for faster previews. Also border rendering and cropping are finally working as expected. Some optimization was done as well.

Python Nodes:
- The API now supports custom node types. Nodes can be defined and registered in python scripts like other UI classes. This allows the creation of entire new node systems for addons, external render engines and the like.

Node Editor:
- Node Groups editing is less cluttered and more consistent with other nodes. Multiple node editor windows can be used independently. Nesting node groups is fully supported. Pinning is supported as well in the node editor to disable context switching.

Usability and Tools:
- New mesh modeling tools: Individual Face Inset, Poke Face and Knife Project. Faster image display in the image and movie clip editors. Better support for UTF-8 text in the text and console editors, and various improvements to other editors.

3D Printing Toolset:
- An addon to help with 3d printing is now bundled as well as a new ruler tool and mesh-analysis display attributes such as thickness, sharp-areas and distortion.

Addons:
- New addons are the node efficiency tools and VRML2 export.

Bug Fixes:
- 3D View

What's new in this version:

Dynamic Topology Sculpting:
- Dynamic topology is a new sculpting mode that subdivides the mesh as needed, whereas regular sculpting only affects the shape of a mesh. This makes it possible to sculpt complex shapes out of a simple mesh, rather than just adding details onto a modeled base mesh.

Rigid Body Simulation:
- The Bullet physics library has now been integrated into the editor and animation system, which makes rigid body simulations available also outside of the game engine. This results in a much simpler workflow and gives more control over the simulation.

UI and Usability:
- Support for MacBook "Retina" Displays was added, proper DPI scaling in all editors, new high-res icons and transparent tool and property regions. User Preferences and Startup File have been split up, new ways to recover sessions were added and copy & paste of objects inside the 3D View is supported now.

Cycles Rendering:
- Initial support for hair rendering was added, multiple importance sampling for lamps, preview rendering is available inside the properties editor, new closures and optimizations for OSL, non-progressive integrator was improved and support for packed, generated and movie textures was added.

Image Transparency:
- The image pipeline has be refactored to handle transparency in images better and compatible to standards. There are two alpha types for images that are useful for different purposes, and we now try to automatically do the right conversions and operations.

Mesh Modeling:
- The Bevel tool supports bevelling individual vertices in addition to edges now, with one or more segments.

Modifiers:
- The new Mesh Cache modifier can apply animation from external files onto a mesh, with support for the MDD and PC2 file formats. A new UV Warp modifier can rotate, scale and translate UV maps on a mesh using objects or bones. The Laplacian smooth modifier now supports shape enhancement, rather than smoothing this will exaggerate the shape of the mesh.

Particle Fluid Dynamics:
- A new SPH particle fluid solver was added, designed for more physically accurate results.

Game Engine:
- The character physics type received a number of new options, profiling and debug information has been cleaned up, and simple shadow maps can now take clipped alpha transparency into account.

- For python scripting two new features were added: library .blend files can now be load asynchronously to keep the game engine from freezing, and joystick events can now be handled from python without logic bricks.

Collada:
- Collada import and export was improved for animation: shape keys are now supported, and the armature modifier has been made more stable, respecting axis orientation and scene scaling.

More Features:
- New features include vertex color baking, more efficient ambient occlusion baking for multires meshes, edge based UV stitching, more control over mapping texture brushes for texture painting, gradient tools for weight painting, and a translate node for the compositor.

Addons:
- Added MilkShape 3D format support and EDL Video Import.

Bug Fixes:
- In addition to the new features, over 250 bugs that existed in previous releases have been fixed.

What's new in this version:

Fire & Smoke Simulation:
- Fire simulation was added to the Smoke Simulator. The domain received major updates to improve performance and usability. Smoke can be emitted from mesh surfaces, without the need for a particle system. A smoke flow force field was added to improve interaction with other simulations. Colored smoke simulation and mixing is possible and the interaction of smoke with collision objects has been improved.

Cycles Rendering:
- Support for writing custom shaders in the Open Shading Language is now available. Motion blur rendering was also added, to make moving objects and cameras appear blurry. There is also an anisotropic shading node, and BSDF nodes can now have different normals, which can be set using the new bump and normal map nodes. Border rendering in the viewport now also works outside of the camera view.

Mesh Modeling:
- The bevel tool now includes rounding and was otherwise much improved, preserving the requested bevel width more evenly and generating better topology. A new symmetrize tool was added to make mesh topology and data symmetric.

Modifiers:
- The decimator was rewritten, and now preserves UV's and vertex colors, has an un-subdivide and a mode to dissolve vertices to create planar n-gons. A new laplacian smooth modifier can reduce noise or smooth the mesh while preserving edges and volume. A triangulate modifier was also added, which can be useful for creating game assets with baked normal maps.

More Features:
- New features include: a tool transfer vertex weights from one mesh to another, antialiased viewport drawing, connected proportional editing in UV editor, improved DPX file read and write, more control over curve taper, collision masks in the game engine and improved camera title safe drawing.

Addons:
- UV texture to vertex color baking was added, the PDB atomic visualization addon was improved, and film response curves were added for the RGB Curves node in the compositor.

Bug Fixes:
- In addition to the new features, over 200 bugs that existed in previous releases have been fixed.

MESH MODELING:
Bevel:
- The bevel tool now includes rounding. Also, the new algorithm is much better at keeping the bevel widths even across the whole model, so the old Even option has been removed. The old Distance option has also been removed: the bevel amount is now always in Blender units, and is the amount that an edge moves along each of its two faces. Only edges with exactly two adjacent faces will be beveled. As with the pre-2.65 bevel, the new one is an interactive tool that you use by selecting the desired edges to bevel and then typing CtrlB. Then move the mouse to change the bevel amount, and use WheelUp Template-MWUP.png and WheelDown Template-MWD.png to increase or decrease the number of segments used for rounding.

Symmetrize:
- The symmetrize operation makes the input mesh elements symmetrical, copying the topology, vertex positions, UV's, from one side to the other. The edges and faces that cross the plane of symmetry are split and connected together as needed to enforce symmetry.

Usage:
- The symmetrize operator is only available in edit mode. It is accessible from the Mesh menu in the 3D View's header and from the Specials menu (W). Select a group of vertices, edges, and/or faces and run the operator. The operator has a "Direction" property that controls the plane of symmetry and whether to flip from positive to negative or negative to positive. This example shows the effect of changing the direction property. The original input mesh is at left. In the middle, it was symmetrized from negative X to positive X. At right, it was symmetrized from positive X to negative X.

Miscellaneous Improvements:
- Holding Alt while scaling normals maintains shell thickness (maintains flat areas better).
- CtrlRMB Template-RMB.png in face select mode now selects the shortest path from the previous active face (matching edge behavior).
- Select Similar tool now has options to select more/less then the active (as well as equal)
- So you can select faces with a greater area than the active face for example.
- Rip-Fill The rip tool now has an option to fill in the gap created by the rip AltV
- The new Laplacian Smooth modifier is available as a tool in the W key menu.


CYCLES:
Open Shading Language:
- Users can now create their own nodes using the Open Shading Language (OSL). Note that these nodes will only work for CPU rendering, there is no support for running OSL code on the GPU. To enable it, select Open Shading Language as shading system in the render settings.

Motion Blur:
- Cycles now supports motion blur rendering for camera and object motion. Previously it was only possible as a post processing effect in compositing, where it is not possible to get fully accurate results and required manual setup of rendering layers. Native motion blur handles transparency, many overlapping objects, and moving light sources. Motion blur from deforming objects is not supported yet.
- A shutter setting controls the time between frames over which motion blur is computed. Shutter time 1.0 blurs over the length of one frame, 2.0 over the length of two frames, from the previous to the next, lower values give less blur.

Shading:
- Per-BSDF normal input and new Bump node. Each BSDF node now has a Normal input, which can be used to set a custom normal for the BSDF, for example if you want to have only bump on one of the layers in a multilayer material. The Bump node can be used to generate a normal from a scalar value, the same as what happens when you connect a scalar value to the displacement output.
- Normal Map node added. The normal maps used are compatible with those baked by Blender Internal
- Anisotropic BSDF shader added, along with a tangent node to specify a tangent direction from generated coordinates or a UV map
- From Dupli option for texture nodes. This gets the Generated and UV coordinates from the duplicator of instance instead of the object itself. This was used in e.g. Big Buck Bunny for texturing instanced feathers with a UV map on the bird
- Ambient Occlusion node added, controlling the amount of AO a surface receives, rather than having just a global factor in the world
- Refraction BSDF node added, for only the refraction component of the existing Glass BSDF

Fisheye Lens:
- Fisheye render was supported since the 2.64 release. But we now have important improvements to facilitate its use.
- Fulldome displays can now directly benefit from a fixed Fisheye Equidistant lens. To render a perfect fulldome fisheye set field of view to 180°
- Sensor size is calculated automatically to match the aspect ratio of the render size. (r52498)
- The viewport preview allows you to correctly see the final image

User Interaction:
- Added back a Progressive Refine method for F12 render. Instead of rendering each tile until it is finished, it refines the whole image progressively. This renders somewhat slower, but time can be saved by manually stopping the render when the noise is low enough
- Border rendering is now also possible outside of the camera view in the 3D viewport. The new shortcut key to set the border is Ctrl + B and to clear the border it is Ctrl + ⇧ Shift + B. The previous shortcut key ⇧ Shift + B still works in camera view, however is already used for zoom to border outside of it
- The number of tiles was replaced with tile size, which gives better control over GPU performance. For CPU rendering a tile size like 32x32 or 64x64 should be fine for practically any scene. For GPU rendering bigger tile sizes should be used for optimal performance. The ideal value can be found out by testing, but 256x256 or 512x512 are good starting values.
- Added memory usage report, which shows device memory used by Cycles.

Optimizations:
- Don't compile shaders and load images that are not used by any mesh/lamp/world
- Persistent Images option to keep images loaded on the device, saved time initializing next rendering

MODIFIERS:
Laplacian Smooth Modifier:
- The Laplacian Smooth modifier allows you to reduce noise on a mesh's surface with minimal changes to its shape. This is useful for objects that have been reconstructed from the real world, containing undesirable noise. A mesh smoothing tool removes noise while still preserving desirable geometry as well as the shape of the original model.
- The Laplacian Smooth modifier is based on a curvature flow Laplace Beltrami operator in a diffusion equation. Full documentation and example .blend files are on the Laplacian Smooth manual page.

Decimate Modifier:
- Edge-Collapse method has support for using a vertex group to control what parts of the mesh are reduced.
The decimator was rewritten, and now preserves UV's and vertex colors. There are now 3 different simplification modes to choose from:
- Edge Collapse - Typical method used to simplify meshes that was used in the original modifier.
- UnSubdivide - Reduce detail on grid-heavy meshes (without giving uneven geometry).
- Planar - Reduces detail on forms comprised of mainly flat surfaces.

Triangulate Modifier:
- Added Triangulate modifier that ensures consistent triangulation. It is especially useful for bump map baking where a consistent triangulation should be enforced when baking/exporting/importing, to avoid artifacts caused by a different triangulation of the mesh by that which was used for baking by internal/external tools. Artifacts are caused by different interpolation of tangent space than the one used during baking. Barycentric interpolation, which is used here, is different for different triangulations of a quad, just like gouraud shading is different for different triangulations. (r52379)

Workflow:
- The triangulation scheme (currently, beauty option on the modifier, but there will be others in the future, such as 1,2,3 - 2,3,4 vertex connection schemes) should remain consistent during these two procedures. Beauty option stands for splitting quads along the shortest diagonal on the modifier, while off will do the opposite.
To ensure correct tangent space interpolation, we need to add a triangulate modifier to ensure the same triangulation in two stages of the pipeline:
- Prior to baking, to the object being baked to
- Prior to exporting or rendering, to ensure the triangulation will remain consistent.
- If the model is animated, triangulation modifier should go before the armature modifier

Other Modifiers:
- Mesh Deform Modifier: binding is now accelerated with a BVH tree, can make it much faster for complex meshes
- Shrinkwrap Modifier: project mode now has a distance limit
- Remesh Modifier: improved performance when used in smooth or blocks mode


FIRE & SMOKE SIMULATION:
Fire Simulation:
- A new flow type has been added to the Smoke Simulator. You can now chose between Fire, Smoke and Smoke & Fire. You can see the fire inside the 3D view preview and the Voxel Data Texture for the Blender Internal has been updated to support the new fire simulator.

Adaptive Domain:
- The Domain resolution and size adapts now to only cover areas where smoke exists, so that the domain can be calculated as small as possible at a time. You can also add additional simulation cells around the original domain area if needed.
- Animating the Domains location is supported now: When you move the domain object during simulation you only move the smoke "boundaries", Smoke itself remains still. This way you can limit the simulated area to stay around moving emitters etc.

Interaction with Force Fields:
- To enable the interaction with other physic simulations, a new fore field type has been added: "Smoke Flow". It applies the smoke simulation air flow velocity as a force. To use it you need to add a "Smoke Flow" force field and select the domain object for it.

Colored Smoke:
- You can now select a custom smoke color for flows and for smoke emitted from fire in the Smoke settings. To render smoke with custom colors enable "Reflection Color" inside the texture settings.

Collision Objects:
- Animated collision objects do no longer block smoke, instead smoke gets transferred velocity from moving collision objects (Video Example)
- Collision objects now cause vorticity when passing through smoke

More Features:
- The Domain is now rotatable. This means you no longer need to align your simulation to the x, y or z axis but you can freely rotate the domain to match the target area.
- Added support for Smoke emission from a mesh surface and volume - without particles.
- Added a new option for volume textures when "Generated" coordinates are used: "Map to Bounds". This maps texture coordinates to the mesh bounding box allowing you to render adaptive domain content. It also solves issues with domains scaled in edit mode.
- The simulation now uses the scene gravity setting, so you can change gravity direction if required.

MORE FEATURES:
Weight Painting:
- Vertex group weights can now be transferred from one object to another, even if they have a different topology. This can be useful for transferring weights between meshes of different resolutions or shapes. The Transfer Weights tool will look for the nearest face or vertex and find the corresponding weight on the other mesh. Weights can be overwritten or added together. The latter can be used as a tool to paint weights from nearby mesh shapes.
- Weight painting now also has a "Limit Weights" tool to restrict the number of vertex groups per vertex, for exporting to game engines that have a fixed limit. (r51217)

Animation:
- Auto Keying: when enabled, a recording icon will be shown during transform to avoid accidentally inserting keys
- Filtering option for graph editor to show only drivers with errors, for debugging broken drivers without looking through all objects
- Follow Path Constraint: "Animation Path" operator added which adds an F-Curve with options for the start and end frame
- Limit Distance Constraint: now supports owner and target space settings. It's advised to use the same space for owner and target, otherwise the comparisons are meaningless
- Parenting and unparenting armatures will now try to avoid adding duplicate modifiers and remove unneeded ones
- Jump to Keyframe: position current frame in the middle of select frames, new shortcut is CtrlG

Camera Tracking:
- Two new options were added to the camera solver: Allow Fallback and Success Threshold. These options enable a simpler bundle reconstruction algorithm which is not as accurate as default one, but which allows to have a reconstruction in cases where the default solver fails.
- Usually it's not needed to use this fallback reconstruction because it could easily lead to cases when object solver will suddenly flip an object. To prevent this the fallback algorithm is disabled by default. However, in some cases it could be really tricky to have an accurate track, which will lead to lots of frames failing to reconstruct. In this case enabling the fallback algorithm could help.
- Success Threshold defines an error threshold which is still considered a successful solution for the default algorithm. The default value is 0.001 but it actually depend on the particular scene (scene scale, number of tracks and so on), so likely it needs to be tweaked to work best in each case.

Curves:
- Added Map Taper option which if enabled maps affect of taper object on actually beveled part of curve (previously the effect of taper would have been clamped by the start/end bevel factor). Here's an illustration of the new option in action

Lattices:
- Added "Flip" tool which flips the lattice coordinates without inverting the normals of lattice deformed meshes. Shortcut is CtrlF

Antialiased Viewport:
- In the User Preferences, under System, the Multisample option can be used to enable antialiased drawing in the viewport (if you graphics card supports it). It will be activated after saving as default and restarting Blender.

Compositing:
- Map Range node added: this maps a value from a given range to another range
- Pixelate node added: this can be added in front of a Scale node to get a pixelated scale

Game Engine:
- Profiling information was improved with a cleaner layout and better naming (r51777)
- Collision mask support added: each object now has a collision mask and a collision group. Object A and object B collide if object A's groups is in object B's mask and object B's group is in object A's mask. In other words, the group defines what the object is (collision wise) and the group defines what the object can collide with
- Character physics controller can now be accessed through the python
- Scene gravity can now be accessed through python
- Mesh.tranform and Mesh.transform_uv utility functions for faster transformation of vertex and uv coordinates
- Video texture depth buffers access

Rendering:
- Materials now have a local light group option for rendering. When a material is linked in and has a light group override, this can now use a local group in the scene file, by replacing the linked light group with a local group that has the same name. A use case might be controlling the specular highlight on linked character's eyes per scene
- Camera: bring Title Safe display up to date, making it a Safe Areas option that shows both title safe and action safe areas following more modern standards
- DPX file format reading was much improved: files can now be loaded and saved in different bit depths and colors spaces, along with various bug fixes.

Tools:
- Operator Reset button was removed, it's now available as Restore Defaults in the presets menu for operators with presets
- Grease Pencil: dynamic sketch option added which makes it possible to created animated curves from grease pencil drawing
- 3D Quad view can now do View All and View Selected for all views at once, with Ctrl↖ Home and CtrlNumpad del shortcuts
- Circle select added for metaball edit mode
- UV editing: support for connected proportional editing. When this is enabled, only UVs on the same island will be proportionally moved
- Axis colors are now themeable, for improved readability when using different color schemes
