Changes for v2.80 - v2.81

• The much anticipated update of the Blender 2.80 milestone is here! With over a thousand fixes and several important updates that were planned for the 2.8 series. Most notable are the sculpting tools overhaul, support for NVIDIA RTX ray tracing in Cycles, Intel Open Image denoising, a better outliner, a new file browser and much more.
• Sculpting Rethought
• A complete overhaul of the sculpting workflow.
• Read more
• New Cursor & Brush Settings
• Auto Masking
• Assigns a factor to each vertex before starting the stroke. Topology automasking affects only vertices connected to the active vertex.
• World Spacing
• Keep an even distance between stroke points in 3D space. Great for sculpting near the edges.
• Grab Active Vertex
• Snaps the maximum strength of the grab brush to the highlighted active vertex, making it easier to manipulate low poly models or meshes with subdivision surfaces.
• Normal Radius
• Control how sensitive the sculpt normal direction is to the underlying surface.
• New Cursor
• Dynamic Mesh Preview
• The cursor now is aligned to the surface normal, displays symmetry and a preview curve fall-off.
• Masking
• Mask Filter
• Modifies the whole paint mask. In includes multiple operations like smooth, grow or contrast accessible from a pie menu.
• Dirty Mask Generator
• Similar to Dirty Vertex Colors, but it generates a paint mask. It can be used to mask cavities in the sculpt.
• Mask Expand
• Creates a mask from the active vertex to the vertex under the cursor based on topology or mesh curvature.
• Mask Extract
• Extracts the paint mask to a new mesh object. It can extract the paint mask creating a boundary loop in the geometry, making it ready for adding a subdivision surface modifier.
• Mask Expand by Curvature
• Mask Extract
• New Tools
• Pose Brush
• Pose a model simulating an armature-like deformation. The pivot point for rotation is calculated automatically based on the radius of the brush and the topology of the model.
• Elastic Deform Brush
• Based on Pixar's paper Regularized Kelvinlets:
• Sculpting Brushes based on Fundamental Solutions of Elasticity, this tool lets you grab, biscale grab, triscale grab, scale and twist operations while preserving volume.
• Translate, Rotate, Scale
• Use the familiar transform tools now also during sculpt. Transforming around a pivot point and taking into account symmetry.
• Draw Sharp Brush
• Similar to the draw brush, but it deforms the mesh from the original coordinates. When used with the sharper curve presets it has a much more pleasant crease/cut behavior than any of the other brushes. It is useful for creating cloth wrinkles, stylized hair or hard surface edges.
• Mesh Filter Tool
• Applies a deformation to all vertices in the mesh at the same time. It includes multiple deformation modes and the option to lock the deformation axis.
• Elastic Deform: Grab
• Elastic Deform: Scale
• Transform Tools in Sculpt Mode
• Remeshing
• Blender 2.81 now ships with two new ways to remesh your models, a fast one based on volumes and another one preserving quads.
• Read more
• OpenVDB Voxel
• Quickly create a new quad mesh based on the volume of the mesh. It is particularly useful for sculpting, to generate a good topology when blocking shapes, as an alternative to dynamic topology without the performance cost of continuous updates.
• QuadriFlow
• Creates a quad mesh with few poles and edge loops following the curvature of the surface. This method is relatively slow but generates higher quality for final topology.
• NVIDIA RTX Support
• Cycles now has experimental support for rendering with hardware-accelerated raytracing on NVIDIA RTX graphics cards. It’s On.
• The OptiX backend was contributed by NVIDIA.
• Intel® Open Image Denoise
• A new Denoise node was added in the compositor, to denoise renders using OpenImageDenoise.

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 v2.63a - v2.64 RC 2

• Mask Editor
• Masks can now be created in the image and movie clip editor. They can be used in compositing to define areas of influence for nodes, block out unwanted objects, or help with green screen keying among other things. A mask datablock was added, consisting of splines that can be drawn and edited with the usual tools. Feathering can be controlled per spline point. Animation of these masks is possible with standard keyframing and drivers, but also by following motion tracks and parenting to other masks.
• Motion Tracker
• Motion tracking was significantly improved by adding planar tracking, and unifying the existing trackers into one Hybrid tracker with finer control. A dopesheet view for markers was added in addition to the curves view. Tripod solving is now supported, for the case where the camera only rotates without moving.
• Green Screen Keying
• Two new compositing nodes have been developed which are aimed at making green screen keying easier. There is now a new keying node conveniently combining various features from existing nodes along with a new keying algorithm, to makes setup much faster. There is also a keying screen node which produces a gradiented plate to deal with uneven colors of green screens.
• Rendering
• Compositing Nodes
• A completely new compositing nodes backend was implemented. This new tiled based compositor gives quicker feedback while editing and uses less memory to support working with high resolutions. New nodes are Switch, Reroute, Bokeh Blur and Image, Box Mask, Ellipse Mask and Color Correction.
• Color Management
• OpenColorIO is now integrated into Blender, along with a redesign of the color management system. Previously Blender only supported radiometrically linear sRGB / BT.REC.709 chromaticities. Now many more are supported with finer control over which color transformations should be used for display, applied on renders, and used for loading and saving image files in different color spaces.
• Cycles Rendering
• Cycles now includes a new non-progressive integrator with finer control over sampling, tiled rendering with support for save buffers, considerably faster BVH building and multithreaded image loading, and motion vector and UV render passes. New nodes are light falloff, object info, particle info and brick texture, and image texture nodes can now do blended box mapping and handle image sequences. There is also support for fisheye camera rendering, along with various other new options.
• Sequencer
• Various speed improvements were implemented in the sequencer, mostly related to caching and multithreading for effect strips. These changes make color grading more interactive. Improved options for comparing the current frame to a reference frame are also available.
• Modeling
• Mesh Tools
• Bevel and inset now are modal operator with mouse control, a wire frame tool was added to turn edges into wireframe tubes, and vertex/edge/face sorting tools were improved.
• Sculpting
• Sculpting has received some major improvements such has masking to control which areas of the mesh are influenced by sculpting, new brush map modes to control how textures are projected onto the model, and an input stroke averaging option to make brush strokes smoother.
• Skin Modifier
• The Skin modifier takes a skeleton made up of vertices and edges as input and generates a polygon skin as output, consisting mostly of quads aligned along the edges. The output is mostly quads, although some triangles will appear around intersections.
• Other
• Game Engine
• Lamps and shadows were improved with support for variance shadow maps, shadow color, sun lamp shadows and lamp textures. Non-power of two textures and compressed textures will now load faster and use less memory. A new Character physics type was added, designed for player controlled characters for which a full dynamics simulation would give unwanted behavior.
• Collada
• The Collada exporter has been improved for better support of export to game engines, with more fine grained options to control which data is exported.
• Small Features
• Apart from the major improvements in different areas, there were lots of smaller changes such as improvements in the node editor, smoke simulation, user interface, and new tools for curves and meshes.
• Bug Fixes
• Lots of new features were added in this release, but it also includes lots of fixes for bugs that existed in previous releases.

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.

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.
