// Versions.  There are three different sets of version numbers:
// (a) The version of the OSL language specification itself, i.e.,
//     what is OSL syntax, semantics, and standard library.
// (b) The version of the OSL library, i.e., this very software whose
//     source code you are reading.
// (c) The version of the .oso file format that this library uses
//     for compiled shaders.
// These are all independent, though loosely coupled.

// Version of this library:
#define OSL_LIBRARY_VERSION_MAJOR 1
#define OSL_LIBRARY_VERSION_MINOR 3
#define OSL_LIBRARY_VERSION_PATCH 1

#define OSL_LIBRARY_VERSION_CODE (10000 * OSL_LIBRARY_VERSION_MAJOR + \
                                    100 * OSL_LIBRARY_VERSION_MINOR + \
                                          OSL_LIBRARY_VERSION_PATCH)

// Version numbers for the compiled shader format.  The major number
// should only be changed if old .oso files should not be expected to
// work with current versions of the library (this should be EXTREMELY
// rare, hopefully never).  The minor number may be changed if newly
// compiled shaders won't work for old libraries, which sometimes
// happens but still should not be often.  Adding a new hint or a new
// shader instruction is not considered a change to the file format!
