help with interface

Hallo, i am new to blender and downloaded ver. 2.6. But i see in tutorial for example Lynda.com the version used has more menu and option than the version 2.6.
would someone explain.

The version used in the Lynda tutorial is probabaly blender version 2.49. The interface changed for the better to the current layout in the blender 2.5 series.
