-High Performance Combinatorics in C++ using vector instructions v1.1.1
+High Performance Combinatorics in C++ using vector instructions v1.1.2
 
 HPCombi is a C++17 header-only library using the SSE and AVX instruction sets,
 and some equivalents, for very fast manipulation of small combinatorial objects
