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!
