Must… mark papers… must resist downloading Blender 2.55.
The Blender Foundation and online developer community is proud to present Blender 2.55 Beta. This release is the third official beta release of
the Blender 2.5 series, representing the culmination of many years of
redesign and development work.
This version is called a “Beta” because it’s now for the most part
feature complete. The Python API has had some extensive changes, most
notably in naming conventions and in creation and access of properties.
Since Blender 2.54 beta over 340 bugs were fixed!
