New release candidate (#1856)

Browse Source 
* Patch for possible AVX-512 overflow.

* Updating the test for new padding.

* Preparing new version.

* replace binary integer literals with hex literals for C++11 compatibility (#1855)

Binary integer literals are a C++14 feature, so those are not supported
in C++11 and should be replaced by hexadecimal literals instead.

Fixes #1854.
