First things first: I decide to change the numbering convention of the OpenGL Samples Pack. From now on, it follows the OpenGL version it requires to run all the samples.
Following this, the OpenGL Samples Pack 3.3.0.0 is an OpenGL 3.3 set of samples that requires OpenGL 3.3 graphics cards and drivers.
It contains 28 samples including 5 new samples: Sampler object, GLSL semantics (explicit location), occlusion query, conditional rendering with any sample and timer query.
Both AMD and nVidia provide beta OpenGL 3.3 drivers but currently both fail to run all the samples correctly. I expect this situation resolved within few weeks maybe a month.
The previous OpenGL Samples Pack for OpenGL 3.2 is still available for developers you prefer reliable drivers.
