For those who are still using blender on Ubuntu 11.04, the version in the Software Center is out of date (2.49). Yes, it does make a difference, there was a major user interface change with the release of Blender 2.5. For those using Blender in Ubuntu 11.10, the version in the Software Center is also out of date(2.57). The current release of Blender is 2.60. Who can I contact go get the versions in the two Software Centers updated? Any help is much appreciated.
