Improvements

• GCC and Clang now issue warnings for suspicious code in assertions (#1880)
  • E.g. REQUIRE( int != unsigned int ) will now issue mixed signedness comparison warning
  • This has always worked on MSVC, but it now also works for GCC and current Clang versions
• Colorization of "Test filters" output should be more robust now
• --wait-for-keypress now also accepts never as an option (#1866)
• Reporters no longer round-off nanoseconds when reporting benchmarking results (#1876)
• Catch2's debug break now supports iOS while using Thumb instruction set (#1862)
• It is now possible to customize benchmark's warm-up time when running the test binary (#1844)
  • --benchmark-warmup-time {ms}
• User can now specify how Catch2 should break into debugger (#1846)

Fixes

• Fixes missing <random> include in benchmarking (#1831)
• Fixed missing <iterator> include in benchmarking (#1874)
• Hidden test cases are now also tagged with [!hide] as per documentation (#1847)
• Detection of whether libc provides std::nextafter has been improved (#1854)
• Detection of wmain no longer incorrectly looks for WIN32 macro (#1849)
  • Now it just detects Windows platform
