Changes made since CMake 3.23 include the following.
-* The ADSP compiler (SHARC and Blackfin) now supports
- both CCES and VDSP++ installations,
- with required configuration now done in the compiler module itself
- rather than the Generic-ADSP platform module.
+New Features
+============
-* A dedicated ``ADSP`` platform has been added
- to replace the existing ``Generic-ADSP`` implementation.
- This features automatic detection of the latest CCES/VDSP++ install
- and compiler selection (``cc21k`` vs. ``ccblkfn``)
- based off of the :variable:`CMAKE_SYSTEM_PROCESSOR` variable.
+Presets
+-------
-* The :genex:`LINK_LIBRARY` generator expression gained the ability to link
- frameworks in various ways when targeting ``Apple`` platforms. The following
- new features were added:
+* :manual:`cmake-presets(7)` files now support schema version ``5``.
- * ``FRAMEWORK``
- * ``NEEDED_FRAMEWORK``
- * ``REEXPORT_FRAMEWORK``
- * ``WEAK_FRAMEWORK``
+* :manual:`cmake-presets(7)` files now support a ``${pathListSep}`` macro,
+ which expands to ``:`` or ``;`` based on the platform.
-* The :genex:`LINK_LIBRARY` generator expression gained the ability to link
- libraries in various ways when targeting ``Apple`` platforms. The following
- new features were added:
+* :manual:`cmake-presets(7)` files gained support for specifying a
+ ``testOutputTruncation`` field in test presets, which specifies the
+ truncation mode once the maximum test output size has been reached.
- * ``NEEDED_LIBRARY``
- * ``REEXPORT_LIBRARY``
- * ``WEAK_LIBRARY``
+Generators
+----------
-* :command:`cmake_host_system_information` command gains the capability, on
- ``Windows`` platform, to query the registry.
+* The :generator:`Green Hills MULTI` generator now generates build
+ rules to re-run CMake if any CMake files are updated.
-* The :manual:`cmake(1)` ``-E tar`` command gained the ``--touch`` option
- to keep the current local timestamp instead of extracting file timestamps
- from the archive.
+* The :ref:`Visual Studio Generators` now support ``SYSTEM`` headers.
+
+Command-Line
+------------
* :manual:`cmake(1)` gained the ``--fresh`` command-line option to remove
- any existing ``CMakeCache.txt`` when configuring a build tree.
+ any existing ``CMakeCache.txt`` when configuring a build tree, thus
+ starting a new configuration as if the build tree were freshly created.
-* The :variable:`CMAKE_PROJECT_TOP_LEVEL_INCLUDES` variable was added to allow
- injecting custom code at the site of the first :command:`project` call,
- after the host and target platform details have been determined.
+* :manual:`cmake(1)` gained the ``--compile-no-warning-as-error`` command-line
+ option which causes the effects of the :prop_tgt:`COMPILE_WARNING_AS_ERROR`

+* The :manual:`cmake(1)` ``--trace=json-v1`` trace format gained fields
+ ``global_frame`` and ``line_end``.
* The :manual:`cmake(1)` ``-E`` commands ``cat`` and ``env`` learned to respect
a double dash (``--``) argument that acts as a delimiter indicating the end of
options. Any following arguments are treated as operands/positional arguments,
even if they begin with a dash ``-`` character.
-* The :variable:`CMAKE_COLOR_DIAGNOSTICS` variable was added to control
- color diagnostics generated by compilers. This variable also controls
- color buildsystem messages with :ref:`Makefile Generators`, replacing
