+Version 1.3.0 changed the names of vector math functions, which are now prepended with ````tinybvh_````, e.g. ````tinybvh_cross````, ````tinybvh_normalize````. This avoids name clashes in applications that override the vector types with their own. Basically ```tinybvh```` evades these so you don't have to. 
 
 Version 1.1.0 introduced a <ins>change to the API</ins>. The single BVH class with multiple layouts has been replaced with a BVH class per layout. You can simply instantiate the desired layout; conversion (and data ownership) is then handled properly by the library. Examples:
