GCC 14.1 released

GCC 14.1 has been released, and it should come as no surprise that the new features are not exactly something I, someone who doesn’t program, can properly parse. So, here’s the three items GCC itself thought were important to list first.

The C frontend when targeting standards newer than C89 now considers many non-standard constructs as errors that were previously only warnings. See https://gcc.gnu.org/gcc-14/porting_to.html#warnings-as-errors for more details. C23 _BitInt Bit-precise integer types are now supported, for now only on IA-32, x86-64 and AArch64.

The C++ frontend now implements several C++26 features, some missing C++23 bits and defect report resolutions. Diagnostics involving C++ templates now quote source from the instantiation context.

The libstdc++exp.a library now includes all symbols for the Filesystem TS and the experimental symbols for the C++23 std::stacktrace class, so -lstdc++exp can be used instead of -lstdc++fs. The libstdc++_libbacktrace.a library is not longer installed. Improved experimental support for C++20, C++23, and C++26. Updated parallel algorithms that are compatible with oneTBB.

GCC 14.1 is available for download, of course, but most of us will get it once it hits our distribution’s package repositories.
