 Changes made since CMake 3.12 include the following.
 
-* The :module:`BundleUtilities` module may no longer be included at configure
-  time. This was always a bug anyway. See policy :policy:`CMP0080`.
+New Features
+============
 
-* The :ref:`Makefile Generators` learned to remove custom command and
-  custom target byproducts during ``make clean``.
+Generators
+----------
 
-* The new variable :variable:`CMAKE_AUTOGEN_VERBOSE` allows
-  to increase the verbosity of :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTOUIC` and
-  :prop_tgt:`AUTORCC` from within CMakeLists.txt.
+* The :ref:`Visual Studio Generators` for VS 2010 and above learned to
+  support the :prop_tgt:`INTERPROCEDURAL_OPTIMIZATION` target property
+  and supporting :module:`CheckIPOSupported` module.
 
-* The :manual:`cmake <cmake(1)>` command gained the ``-S <source_dir>``
-  command line option to specify the location of the source directory.
-  This option can be used independently of ``-B``.
+* The :generator:`Xcode` generator learned to configure more Xcode Scheme
+  fields.  See the :variable:`CMAKE_XCODE_GENERATE_SCHEME` variable.
 
-* The :manual:`cmake <cmake(1)>` command gained the ``-B <build_dir>``
-  command line option to specify the location of the build directory.
-  This option can be used independently of ``-S``.
+* The :generator:`Green Hills MULTI` generator has been udpated:
 
-* The :cpack_gen:`CPack Deb Generator` learned to split debug symbols into
-  a corresponding .ddeb package when ``CPACK_DEBIAN_DEBUGINFO_PACKAGE`` is
-  set.
+  - Added support for architecture selection through
+    :variable:`CMAKE_GENERATOR_PLATFORM`:
+    e.g. ``arm``, ``ppc``, and ``86``.
 
-* The :cpack_gen:`CPack Deb Generator` learned to honor the ``SOURCE_DATE_EPOCH``
-  environment variable when packaging files.  This is useful for generating
-  reproducible packages.
+  - Added support for toolset selection through
+    :variable:`CMAKE_GENERATOR_TOOLSET`,
+    e.g. ``comp_201205``, ``comp_201510``, ``comp_201722_beta``.
 
-* CPack gained a new :cpack_gen:`CPack External Generator` which is used to
-  export the CPack metadata in a format that other software can understand. The
-  intention of this generator is to allow external packaging software to take
-  advantage of CPack's features when it may not be possible to use CPack for
-  the entire packaging process.
+  - Added support for platform selection through ``GHS_TARGET_PLATFORM``,
+    e.g. ``integrity``, ``linux``, ``standalone``, etc.
+
+  - No longer checks that ``arm`` based compilers are installed but ensures
+    that the correct ``gbuild.exe`` exists.
+
+  - No longer hard-codes ARM files, BSP, toolset, or OS locations.
 
-* The CPack generators have been moved into their own separate section in the
-  documentation, rather than having the documentation in their internal
-  implementation modules.
-* These internal implementation modules are also no longer available to scripts
-  that may have been incorrectly including them, because they should never have
-  been available in the first place.
+Command-Line
+------------
+
+* The :manual:`cmake(1)` command gained the ``-S <source_dir>``
+  command line option to specify the location of the source directory.
+  This option can be used independently of ``-B``.
+
+* The :manual:`cmake(1)` command gained the ``-B <build_dir>``
+  command line option to specify the location of the build directory.
+  This option can be used independently of ``-S``.
 
 * The :manual:`cmake(1)` ``-E create_symlink`` command can now be used
   on Windows.
 
-* :manual:`ctest(1)` gained a ``--progress`` option to enable a live
-  test progress summary when output goes to a terminal.
+Commands
+--------
 
 * The :command:`add_custom_command` and :command:`add_custom_target` commands
   learned to support generator expressions in ``WORKING_DIRECTORY`` options.
 
-* An explicit deprecation diagnostic was added for policies ``CMP0055``
-  through ``CMP0063`` (``CMP0054`` and below were already deprecated).
-  The :manual:`cmake-policies(7)` manual explains that the OLD behaviors
-  of all policies are deprecated and that projects should port to the
-  NEW behaviors.
+* The :command:`add_link_options` command was created to add link
+  options in the current directory.
+
+* The :command:`install(CODE)` and :command:`install(SCRIPT)` commands
+  learned to support generator expressions.
+
+* The :command:`install(TARGETS)` command learned to install targets
+  created outside the current directory.
+
+* The :command:`link_directories` command gained options to control
+  insertion position.
+
+* The :command:`list(SORT)` command gained options to control the
+  comparison operation used to order the entries.
+
+* The :command:`math` command gained options for hexadecimal.
+
+* The :command:`target_link_directories` command was created to
+  specify link directories for targets and their dependents.
+
+* The :command:`target_link_options` command was created to
+  specify link options for targets and their dependents.
+
+* The :command:`target_link_libraries` command may now be called
+  to modify targets created outside the current directory.
+  See policy :policy:`CMP0079`.
+
+Variables
+---------
+
+* A :variable:`CMAKE_AUTOGEN_VERBOSE` variable was added to optionally
+  increase the verbosity of :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTOUIC`
+  and :prop_tgt:`AUTORCC` from within CMake project code.
+
+* A :variable:`CMAKE_VS_GLOBALS` variable was added to initialize
+  :prop_tgt:`VS_GLOBAL_<variable>` target properties on targets as
+  they are created.
+
+Properties
+----------
+
+* The :prop_tgt:`DEPLOYMENT_ADDITIONAL_FILES` target property was
+  added to tell the :generator:`Visual Studio 9 2008` generator
+  to specify additional files for deployment to WinCE devices
+  for remote debugging.
+
+* The :prop_tgt:`INTERFACE_LINK_DEPENDS` target property was created
+  to specify transitive link dependencies on files.
+
+* The :prop_tgt:`LINK_DEPENDS` target property learned to support
+  :manual:`generator expressions <cmake-generator-expressions(7)>`.
+
+* :prop_tgt:`LINK_DIRECTORIES` and :prop_tgt:`INTERFACE_LINK_DIRECTORIES`
+  target properties were added to collect link directories for a target
+  and its dependents.  Use the :command:`target_link_directories` command
+  to set them.
+
+* :prop_tgt:`LINK_OPTIONS` and :prop_tgt:`INTERFACE_LINK_OPTIONS` target
+  properties were added to collect link options for a target and its
+  dependents.  Use the :command:`target_link_options` command to set them.
+
+* A :prop_dir:`LINK_OPTIONS` directory property was added to collect
+  link options for targets created under the current directory.
+  Use the :command:`add_link_options` command to set it.
+
+* A :prop_tgt:`STATIC_LIBRARY_OPTIONS` target property was created
+  to specify archiver options to use when creating static libraries.
+
+* A :prop_tgt:`VS_DEBUGGER_COMMAND_ARGUMENTS` target property was created to
+  set the debugging command line arguments with
+  :ref:`Visual Studio Generators` for VS 2010 and above.
+
+* A :prop_tgt:`VS_DEBUGGER_ENVIRONMENT` target property was created to
+  set the debugging environment with
+  :ref:`Visual Studio Generators` for VS 2010 and above.

+* The :prop_tgt:`VS_DEBUGGER_COMMAND` and
+  :prop_tgt:`VS_DEBUGGER_WORKING_DIRECTORY` target properties
+  now support generator expressions.
