v3.5.4

Fixes

• Fixed potential compilation error when asked to generate random integers whose type did not match std::(u)int*_t.
  • This manifested itself when generating random size_ts on MacOS
• Added missing outlined destructor causing Wdelete-incomplete when compiling against libstdc++ in C++23 mode (#2852)
• Fixed regression where decomposing assertion with const instance of std::foo_ordering would not compile

Improvements

• Reintroduced support for GCC 5 and 6 (#2836)
  • As with VS2017, if they start causing trouble again, they will be dropped again.
• Added workaround for targetting newest MacOS (Sonoma) using GCC (#2837, #2839)
• CATCH_CONFIG_DEFAULT_REPORTER can now be an arbitrary reporter spec
  • Previously it could only be a plain reporter name, so it was impossible to compile in custom arguments to the reporter.
• Improved performance of generating 64bit random integers by 20+%

Miscellaneous

• Significantly improved Conan in-tree recipe (#2831)
• DL_PATHS in catch_discover_tests now supports multiple arguments (#2852, #2736)
• Fixed preprocessor logic for checking whether we expect reproducible floating point results in tests.
• Improved the floating point tests structure to avoid Wunused when the reproducibility tests are disabled (#2845)
