Changes for v2.67b - v2.68

• The Blender Foundation and online developer community is proud to present Blender 2.68.
• Many different mesh modelling tools were added and improved. Cycles render performance was improved on Windows and on GPU's. The motion tracker can now automate placement and choice of markers more with new tools. Smoke rendering quality has been improved to reduce blockiness.
• Python scripts and drivers are now disabled by default when loading files. This is for improved security, without this feature malicious .blend files could cause problems. See the Python security documentation for details.
• 2.68 release: July 18th, 2013.
• Modeling
• Improved bridge tool to bridge multiple loops at once, subdivision, surface blending and bridging face regions. New grid-fill tool filling a grid from edge loops, X mirror and projected proportional editing, snap to symmetry, face split option for dissolve, vertex connect cut across faces.
• Physics
• Smoke has improved rendering quality avoid blockiness, and subframe simulation support to handle fast moving emitters. Particles can now be emitted from faces generated by modifiers that were not in the original mesh.
• Usability
• Improved weight painting tools, mask modifier for sequencer strips, 2D image paint more consistent with 3D painting, better key shortcuts display, quick enabling and disabling of multiple layers or visibility, auto indent for multi-line Python statements,
• Addons
• New addons are Texture Atlas to bake shadow and lightmaps for an entire scene, and Edit Linked Library, for quick editing of linked assets.
• Cycles Render
• Rendering performance has been improved on CPU and GPU and support for new GPUs was added. A new Mist render pass is available, Ray visibility is now supported for all light sources, and new Nodes have been added. Hair rendering on the GPU has been enabled as well.
• Motion Tracker
• Some new features and smaller improvements to existing ones were done for motion tracking. Main features are markers' position refining, which allows you to refine marker position after it was occluded by an object, and automatic keyframe selection, which tries to automatically find a best keyframe for the reconstruction.
• Python Security
• Auto-running Python scripts can now be controlled more securely.
• Bug fixes
• In addition to the new features, over 280 bugs that existed in previous releases have been fixed.

Changes for v2.66a - v2.67

• The Blender Foundation and online developer community is proud to present Blender 2.67. New in this release is the Freestyle render engine for non-photorealistic rendering, which can generate 2D line drawings in various styles.
• The paint and sculpt system is now much more consistent across different paint modes and has gained various new features. Motion tracking was made faster, and Cycles now has initial support for subsurface scattering.
• The node system now support more flexible group editing. For developers of external render engine addons it is now possible to support node based materials.
• For 3D printing an addon was added to analyze and export the meshes.
• 2.67 release: May 7th, 2013.
• Freestyle
• 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.
• 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.
• 3D Printing
• 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.
• Cycles Render
• 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.
• Addons
• New addons are the node efficiency tools and VRML2 export.
• Bug fixes
• In addition to the new features, over 260 bugs that existed in previous releases have been fixed.
• Paint System
• 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.
• Compositing
• 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.
• 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.
• 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.
• 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.

Changes for v2.64a - v2.65

• The Blender Foundation and online developer community is proud to present Blender 2.65. We focused on making this the most stable release in the 2.6 cycle yet, fixing over 200 bugs.
• Fire simulation was added along with many improvements in smoke simulation. In Cycles, motion blur, open shading language and anisotropic shading support was added. For mesh modeling, the bevel tool was much improved, a new symmetrize mesh tool was added, and new Laplacian smooth, decimate, and triangulate modifiers are available.
• 2.65 release: December 10th, 2012.
• Fire and Smoke
• 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.
• 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.
• 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.
• Bug fixes
• In addition to the new features, over 200 bugs that existed in previous releases have been fixed.
• Cycles Render
• 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.
• 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.
• 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.

---

Changes for v2.63 RC 1 - v2.63

• This release was focused on integrating and stabilizing the long awaited BMesh modelling system, which has full support for N-sided polygons and many new modelling tools. New tools include Dissolve, Inset, Bridge, Vertex Slide, Vertex Connect, Bevel, and improved versions of Knife, Subdivide and Rip.

---

Changes for v2.62 - v2.63 RC 1

• BMesh
• BMesh is the new Blender mesh system with full support for N-sided polygons instead of only triangles and quads.
• In particular there is a new Dissolve tool to remove vertices, edges and faces without making holes in the mesh, a new Inset tool to inset faces, and a much improved Knife tool which takes advantage of N-gons to generate clear cuts. Tools such as subdivide and loop cut will also generate clean topology because faces no longer have to be triangulated.
• Cycles
• Among the features added in this release are support for rendering environment maps, render layer mask layers, a shadow render pass, ambient occlusion and float precision textures.
• Motion Tracker
• Motion tracking got some improvements which are mostly relates on 2D stabilization and few smaller tools.
• More Features
• Other new features in this release include face hiding for sculpting, a compositing node to output multiple files at once or multilayer EXR files, new tools for linking and detaching nodes and more particle rotation options.
• Addons
• Bug Fixes
• This release was mainly focused on stabilizing BMesh, but also includes 110 fixes for bugs that existed in previous releases.

Changes for v2.58 - v2.58a

• Additions
• More flexible size options for particle billboards. This adds scale factors for width and height of billboards, relative to the particle size. It's useful when the particle size is primarily used for collision and the like, so the billboard appearance can be adjusted independently. Also allows non-square billboards.
• In addition the billboards can be scaled by the particle velocity with optional head and tail factors (similar to line drawing options). This allows for pseudo-motionblur effects. - r37760
• Addon UI: button for removing addons which are installed to user/home paths - r37950
• Python API:
• Python application event handlers - r37795
• adds bpy.app.handlers which contains lists, each for an event type:
• render_pre, render_post, load_pre, load_post, save_pre, save_post
• each list item needs to be a callable object which takes 1 argument (the ID).
• callbacks are cleared on file load.
• mathutils.geometry.intersect_line_sphere(l1, l2, sphere, radius, clip=True) - r37820
• RenderEngine API: add self.report() error reporting function for render engines, works the same as for operators. - r37916

Changes for v2.57b - v2.58

• Blender 2.58 update log
• The majority of work for 2.58 went into fixes with over 200 bugs fixed since last release but there are also quite a few useful additions worth checking out.
• Prominent features (the cool stuff)
• Warp Modifier:
• Changelog 2 58 warp.png
• This deformation modifier can be used to warp parts of a mesh to a new location in a very flexible way by using 2 objects to select the "from" and "to" regions with options for using a curve falloff, texture and vertex group.
• Render Baking:
• For high polygon models it is now possible to bake multi-resolution models using much less memory than before. There are also new bake modes: specular color, specular intensity, mirror color, mirror intensity, alpha (transparency), emission (glow)
• Empty Images Display:
• Changelog 2 58 empty image.png
• Instead of using background images or creating meshes with materials and image texture it's now possible to assign images directly to empty objects to use as reference images. They display in all draw modes and can use object draw options like XRay to draw over other objects.
• Sculpting:
• Constructive modifiers (like subdivision surface, mirror and other) were supported for sculpting mode. Sculpting could be not very accurate with such modifiers enabled, so there is a new option in the toolbar to disable applying constructive modifiers in the sculpting session.
• Mesh Inset (Addon):
• Changelog 2 58 polygon inset.png
• Mesh inset is a very useful tool with the ability to inset individual faces or a selected region.
• Camera Locking:
• It is now possible to move the camera using normal view port navigation by enabling "Lock Camera" in the "View" panel.
