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.
+- 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.
