 What's New in Libc++ 13.0.0?
 ============================
 
+- Support for older compilers has been removed. Several additional platforms
+  are now officially supported. :ref:`platform_and_compiler_support` contains
+  the complete overview of platforms and compilers supported by libc++.
+- The large headers ``<algorithm>``, ``<iterator>``, and ``<utility>`` have
+  been split in more granular headers. This reduces the size of included code
+  when using libc++. This may lead to missing includes after upgrading to
+  libc++13.
+
 New Features
 ------------
 
-- ...
+- ``std::filesystem`` is now feature complete for the Windows platform using
+  MinGW. MSVC isn't supported since it lacks 128-bit integer support.
+- The implementation of the C++20 concepts library has been completed.
+- Several C++20 ``constexpr`` papers have been completed:
+
+  - `P0879R0 <https://wg21.link/P0879R0>`_ ``constexpr`` for ``std::swap()``
+    and swap related functions
+  - `P1032R1 <https://wg21.link/P1032R1>`_ Misc ``constexpr`` bits
+  - `P0883 <https://wg21.link/P0883>`_ Fixing Atomic Initialization
+
+- More C++20 features have been implemented. :doc:`Status/Cxx20` has the full
+  overview of libc++'s C++20 implementation status.
+- More C++2b features have been implemented. :doc:`Status/Cxx2b` has the
+  full overview of libc++'s C++2b implementation status.
+- The CMake option ``LIBCXX_ENABLE_INCOMPLETE_FEATURES`` has been added. This
+  option allows libc++ vendors to disable headers that aren't production
+  quality yet. Currently, turning the option off disables the headers
+  ``<format>`` and ``<ranges>``.
+- The documentation conversion from html to restructured text has been
+  completed.
