+
+Changes since Cg 2.2 October 2009
+---------------------------------
+- Bug fixes
+  - Require EXT_gpu_shader4 in GLSL when using bit shift/mask instructions
+  - Modified example gs_simple to explicitly use the GLSL profiles if supported
+  - HLSL semantic VFACE is now accepted as an alias for semantic FACE
+  - Improved our handling of extensions on older versions of OpenGL
+  - Various performance improvements
+  - Enhanced cgfxcat to work for program files as well as effect files
+  - Fixed some compiler crashes with malformed shaders
+  - Fixed a crash in cgGetParameterBufferIndex and cgGetParameterBufferOffset
+  - Fixed a bug in cgGetPassProgram for combined programs
+  - Fixed a problem with geometry shaders on Solaris
+
+Changes since Cg 2.2 April 2009
+-------------------------------
+- New features
+  - Allow compiler options in effect compile statements
+      - e.g. VertexProgram = compile vp40 "-po PosInv=1" shader();
+  - Better performance when running on multicore CPUs
+  - Choosing the "latest" profile is now deferred until effect validation
+  - Now using MesaGLUT-7.5 for GLUT on Windows
+- Bug fixes
+  - Improved the inverse matrix computation in cgGLSetStateMatrixParameter
+  - Better memory behavior when a program is repeatedly recompiled
+  - Fixed an issue when using PSIZE semantic with ps_3_0 and ps_4_0 profiles
+  - cgCombinePrograms now works with CG_OBJECT programs
+  - cgGetNextProgram was always returning 0
+  - Fixed a problem with effect parameters and cgGLGetTextureEnum
+  - Allow comments prior to the shader version in D3D asm blocks of an effect
+  - HLSL10: Mark globally scoped temporaries 'static' to keep them out of constant buffers
+  - HLSL10: Allow any semantic for varyings provided the semantics match between stages
+  - HLSL10: Fix handling of TEXUNITn semantic
+  - HLSL10: Added support for arrays of samplers
+  - HLSL10: Empty structs for uniform parameters crashed the D3D compiler
+  - Fixed a problem when connecting parameters of type string
+  - Corrected issues in the fp20 profile on Solaris
+
