is opengl 4.1 backwards compatible with 3.2

New ARB extension like: ability to set stencil values in a fragment shader.New ARB extensions like: OpenGL sync objects to OpenCL event objects.

Multiple viewports for a rendering surface for increased rendering flexibility.64-bit floating point component vertex shader inputs for higher geometric precision.The capability to bind programs individually to programmable stages for programming flexibility.The ability to query and load a binary for shader program objects to save recompilation time.Full compatibility with OpenGL ES 2.0 APIs.

New core functionality in OpenGL 4.1 includes: This version continues to maintain full backwards compatibility to enable developers to begin using new features whenever they choose, while portably accessing state-of-the-art GPU functionality across diverse operating systems and platforms. OpenGL 4.1 is the sixth update to the OpenGL specification in two years. OpenGL 4.1 brings the latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface). The conference takes place in Los Angeles. The Khronos Group has announced the immediate availability of the OpenGL 4.1 specification at the SIGGRAPH 2010 conference this week.
