Version history for Blender (64-bit)

<<Back to software description

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 v2.61 - v2.62

The Blender Foundation and online developer community is proud to present Blender 2.62. The 2.6x series is being targeted at including all work that happened in branches or patches past years.
The Cycles render engine now has layers/passes, you can track objects inside videos now, have much better and faster boolean intersections and use great new UV Tools.

Changes for v2.59 - v2.60 RC

http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/changelog_260

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.
