CUB 1.10.0 (NVIDIA HPC SDK 20.9)

Summary

CUB 1.10.0 is the major release accompanying the NVIDIA HPC SDK 20.9 release. It drops support for C++03, GCC < 5, Clang < 6, and MSVC < 2017. It also overhauls CMake support. Finally, we now have a Code of Conduct for contributors: https://github.com/thrust/cub/blob/main/CODE_OF_CONDUCT.md

Breaking Changes

• C++03 is no longer supported.
• GCC < 5, Clang < 6, and MSVC < 2017 are no longer supported.
• C++11 is deprecated. Using this dialect will generate a compile-time warning. These warnings can be suppressed by defining CUB_IGNORE_DEPRECATED_CPP_DIALECT or CUB_IGNORE_DEPRECATED_CPP_11. Suppression is only a short term solution. We will be dropping support for C++11 in the near future.
• CMake < 3.15 is no longer supported.
• The default branch on GitHub is now called main.
