+New Features
+============
+
+Languages
+---------
+
+* C++ 20 named modules are now supported by :ref:`Ninja Generators`
+  and :ref:`Visual Studio Generators` for VS 2022 and newer, in combination
+  with the MSVC 14.34 toolset (provided with VS 17.4) and newer, LLVM/Clang
+  16.0 and newer, and GCC 14 (after the 2023-09-20 daily bump) and newer.
+  See :manual:`cmake-cxxmodules(7)` for details.
+
+* ``HIP`` language code may now be compiled for NVIDIA GPUs
+  using the NVIDIA CUDA Compiler (NVCC).
+  See the :variable:`CMAKE_HIP_PLATFORM` variable.
+
+Platforms
+---------
+
+* On Apple platforms, ``.xcframework`` folders are now supported:
+
+  * The :command:`find_library` command now finds ``.xcframework`` folders.
+
+  * The :command:`target_link_libraries` command now supports
+    linking against a ``.xcframework`` folder.
+
+  * The :prop_tgt:`IMPORTED_LOCATION` target property of an imported
+    library target may now be the path to a ``.xcframework`` folder.
+
+* Apple visionOS and its ``xros`` and ``xrsimulator`` SDKs are now supported.
   Compiling for Apple visionOS can be requested by setting
-  :variable:`CMAKE_SYSTEM_NAME` to ``visionOS``. For more
-  information see :manual:`cmake-toolchains(7)`.

+
+Variables
+---------
 
 * The :envvar:`CMAKE_CROSSCOMPILING_EMULATOR` environment variable
   was added to initialize the :variable:`CMAKE_CROSSCOMPILING_EMULATOR`
   cache variable.
 
-* The :command:`add_custom_command` and :command:`add_custom_target`
-  commands gained a ``JOB_SERVER_AWARE`` option.

+  System and expect the project to be set-up for their current
