The OpenCL 1.1 specification was ratified by the Khronos Group on June 14, 2010. It adds additional functionality for parallel programming and performance, including the following:

• New data types including 3-component vectors and additional image formats
• Handling commands from multiple host threads and processing buffers across multiple devices
• Operations on regions of a buffer including reading, writing, and copying of the 1D, 2D, or 3D rectangular regions
• Enhanced use of events to drive and control command execution
• Additional OpenCL built-in C functions, such as integer clamp, shuffle, and asynchronous-strided (not contiguous, but with gaps between the data) copies
• Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL and OpenGL events
