1.13.2

• Changes to conventional/Engine.hpp:
  • The sequence of generated randoms is unchanged.
  • shrink the memory footprint by not keeping a copy of the ukey in the Engine and storing the 'elem' counter in v.back().
  • insertion and extraction operators have changed incompatibly. I.e., engines serialized with 1.10 or earlier cannot be deserialized with 1.11, and vice versa.
  • getkey returns a key_type and setkey takes a key_type.
  • when ukey_type is not the same as key_type, provide a constructor and a seed method that takes a const key_type& argument.
  • the getseed method is eliminated.
• Move uniform.hpp, boxmuller.hpp and u01fixedpt.h into include/Random123. I.e., make them available in exactly the same way as threefry.h, et al. It is no longer necessary to copy them from the examples directory to user code.
• Incorporate ua.hpp into uniform.hpp.
• Provide insertion, extraction and comparison operators to the aesopenssl16x8_key_t and aesni1xm128_key_t.
• Separate tests and benchmarks (which are absurdly complicated) from examples (which are meant to be short and simple) in the source tree. We still test and time the same things, but all that code is in tests/, while the code remaining in examples/ really tries to be exemplary.
• More careful use cl_uint and elimination of uint from opencl code.
• Better (but not reliable) support for OpenCL on MacOS.
• Fix documentation for examples/uniform.hpp.
• Don't try to declare reverse iterators for r123array in cuda.
• Add support for Apple's Metal Shading Language (2.1) - contributed by Tom Schoonjans.
  • Implementation of 32-bit threefry and philox.
  • metalfeatures.h, plus new macros in compilerfeatures.h, used in threefry.h, philox.h and kat infrastructure.
  • tests/kat_metal and examples/pi_metal
• Small tweaks to silence warnings from newer gcc, clang, cuda and opencl.
• Cosmetic changes to doxygen markup, including fixes to work with newer releases of doxygen.
