+/* This is a draft release of gl3.h, a header for use with OpenGL 3.1, and
+ * 3.2 and later core profile implementations. The current version is
+ * available at http://www.opengl.org/registry/ . Please don't package
+ * gl3.h for release with other software until it's out of draft status.
+ * The structure of the file may change significantly, and the details
+ * will probably change slightly as we make sure exactly the right set
+ * of interfaces is included.
+ *
+ * gl3.h last updated on $Date: 2012-04-26 00:59:42 -0700 (Thu, 26 Apr 2012) $
+ *
+ * RELEASE NOTES - 2012/04/25
+ *
+ * gl3.h should be placed under a directory 'GL3' and included as
+ * '<GL3/gl3.h>'.
+ *
+ * gl3.h is supposed to only include APIs in a OpenGL 3.1 (without
+ * GL_ARB_compatibility) or OpenGL 3.2-4.2 (inclusive) core profile
+ * implementation, as well as interfaces for newer ARB extensions which
+ * can be supported by the core profile. It does not, and never will
+ * include functionality removed from the core profile, such as
+ * fixed-function vertex and fragment processing.
+ *
+ * Implementations of OpenGL 3.1 supporting the optional
+ * GL_ARB_compatibility extension continue to provide that functionality,
+ * as do implementations of the OpenGL 3.2+ compatibility profiles, and
+ * source code requiring it should use the traditional <GL/gl.h> and
+ * <GL/glext.h> headers instead of <GL3/gl3.h>.
+ *
+ * It is not possible to #include both <GL3/gl3.h> and either of
+ * <GL/gl.h> or <GL/glext.h> in the same source file.
+ *
+ * We welcome feedback on gl3.h. Please register for the Khronos Bugzilla
+ * (www.khronos.org/bugzilla) and file issues there under product
+ * "OpenGL", category "Registry". Feedback on the opengl.org forums
+ * may not be responded to in a timely fashion.
