+ <li>Support for many previously unavailable features in freestanding mode,
+ thanks to Arsen Arsenović. For example, <code>std::tuple</code> is
+ now available for freestanding compilation. The freestanding subset
+ contains all the components made freestanding by
+ <a href="https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p1642r11.html">P1642</a>,
+ but libstdc++ adds more components to the freestanding subset,
+ such as <code>std::array</code> and <code>std::string_view</code>.
+ Additionally, libstdc++ now respects the <code>-ffreestanding</code>
+ compiler option and so it is not necessary to build a separate
+ freestanding installation of libstdc++. Compiling with
+ <code>-ffreestanding</code> will restrict the available features to
+ the freestanding subset, even if libstdc++ was built as a full, hosted
+ implementation.
