Story

The release includes AMD Zen 6 support, Intel AVX10.2, and a new SARIF diagnostic output format. The C++20 default change alone affects every C++ project that doesn't explicitly pin a standard version. If your CI builds with GCC and you haven't tested against C++20, you might be in for surprises.
