New Features ------------ +- Random device support has been made optional. It's enabled by default and can + be disabled by building libc++ with ``-DLIBCXX_ENABLE_RANDOM_DEVICE=OFF``. + Disabling random device support can be useful when building the library for + platforms that don't have a source of randomness, such as some embedded + platforms. When this is not supported, most of ``<random>`` will still be + available, but ``std::random_device`` will not. +- Localization support has been made optional. It's enabled by default and can + be disabled by building libc++ with ``-DLIBCXX_ENABLE_LOCALIZATION=OFF``. + Disabling localization can be useful when porting to platforms that don't + support the C locale API (e.g. embedded). When localization is not + supported, several parts of the library will be disabled: ``<iostream>``, + ``<regex>``, ``<locale>`` will be completely unusable, and other parts may be + only partly available. +- If libc++ is compiled with a C++20 capable compiler it will be compiled in + C++20 mode. Else libc++ will be compiled in C++17 mode. +- Several unqualified lookups in libc++ have been changed to qualified lookups. + This makes libc++ more ADL-proof. +- The libc++ implementation status pages have been overhauled. Like other parts + documentation they now use restructured text instead of html. Starting with + libc++12 the status pages are part of libc++'s documentation. +- More C++20 features have been implemented. :doc:`Cxx2aStatus` has the full + overview of libc++'s C++20 implementation status. +- Work has started to implement new C++2b features. :doc:`Cxx2bStatus` has the + full overview of libc++'s C++2b implementation status. -- ...
