 * changes v6.2.3 -> v6.2.x
 
+##
+## Bugs
+##
+
+- Fixed autotune unitialized tmps variable for slow hashes by calling _init kernel before calling _loop kernel
+- Fixed datatype in function sha384_hmac_init_vector_128() that could come into effect if vector datatype was manually set
+
+
+##
+## Improvements
+##
+
+- Blake Kernels: Optimize BLAKE2B_ROUND() 64 bit rotates giving a 5% performance increase
+
+##
+## Technical
+##
+
+- HIP Kernels: Got rid of hip/hip_runtime.h dependancy to enable more easy integration of the HIP backend on Windows
+
 * changes v6.2.2 -> v6.2.3
