Release Notes: Various performance optimizations have been made. GPU support has been enhanced with new Optical Flow algorithms, new feature detectors and descriptors, and overall GPU module enhancements. It now supports CUDA 4.1 and CUDA 4.2, and can be compiled with CUDA 5.0 preview. An enormous amount of new functionality has been added. Addition of new modules has been made much easier.

Release Notes: Many functions and methods now take InputArray/OutputArray instead of "cv::Mat" references. LAPACK was replaced by an implementation of Jacobi SVD, decreasing footprint and compile time, and improving performance and accuracy. New BRIEF and ORB feature descriptors were added. A new calibration pattern "circles grid" was added. A new experimental variational stereo correspondence algorithm StereoVar was added. Support for Ximea cameras was added. Python modules were enhanced. Various other enhancements were made. Documentation was improved. Many bugs were fixed.

Release Notes: The library was reorganized into 12 smaller instead of 4 larger modules, while maintaining backward compatibility. An experimental CUDA acceleration module was added. Many improvements and enhancements were made. Bugs were fixed.
