This behavior change may expose + bugs in existing projects that were relying on undocumented implementation + details. Specifying compile features only ensures that the compiler runs + in a mode that has those features, not that any specific standard level is + used or explicit ``-std=`` flag passed. + * CMake learned how to compile C++14 with the IBM AIX XL compiler and the SunPro compiler and to compile C++20 with the AppleClang compiler. |
