+- update to version 0.6.5
+  -  Improved performance on small keys, thanks to suggestions from Jens Bauer
+  -  New build macro, XXH_INLINE_ALL, extremely effective for small keys of fixed length (see this article for details)
+  -  XXH32() : better performance on OS-X clang by disabling auto-vectorization
+  -  Improved benchmark measurements accuracy on small keys
+  -  Included xxHash specification document

 %description
 xxHash is an Extremely fast Hash algorithm, running at RAM speed limits. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical on all platforms (little / big endian).
