 Changes made since CMake 3.4 include the following.
 
-* Support was added for the ARM Compiler (arm.com) with compiler id ``ARMCC``.
-
-* A new platform file for cross-compiling in the Cray Linux Environment to
-  target compute nodes was added.  See
-  :ref:`Cross Compiling for the Cray Linux Environment <Cray Cross-Compile>`
-  for usage details.
-
-* The :module:`CPackDMG` module learned new variable to specify AppleScript
-  file run to customize appearance of ``DragNDrop`` installer folder,
-  including background image setting using supplied PNG or multi-resolution
-  TIFF file.  See the :variable:`CPACK_DMG_DS_STORE_SETUP_SCRIPT` and
-  :variable:`CPACK_DMG_BACKGROUND_IMAGE` variables.
+New Features
+============
 
-* The :manual:`cmake(1)` ``-E copy`` and ``-E copy_if_different`` command-line
-  tools learned to support copying multiple input files to a directory.
+GUI
+---
 
-* The :manual:`cmake(1)` ``-E copy_directory`` command-line
-  tool learned to support copying multiple input directories to a directory.
-
-* The :manual:`cmake(1)` ``-E make_directory`` command-line
-  tool learned to support copying multiple input directories to a directory.
-
-* The :manual:`cmake(1)` ``-E time`` command now properly passes arguments
-  with spaces or special characters through to the child process.  This
-  may break scripts that worked around the bug with their own extra
-  quoting or escaping.
+* The :manual:`cmake-gui(1)` gained options to control warnings about
+  deprecated functionality.
 
 * The :manual:`cmake-gui(1)` learned an option to set the toolset
   to be used with VS IDE and Xcode generators, much like the
   existing ``-T`` option to :manual:`cmake(1)`.
 
-* The :command:`cmake_parse_arguments` command is now implemented natively.
-  The :module:`CMakeParseArguments` module remains as an empty placeholder
-  for compatibility.
+* The :manual:`cmake-gui(1)` gained a Regular Expression Explorer which
+  may be used to create and evaluate regular expressions in real-time.
+  The explorer window is available via the ``Tools`` menu.
 
-* The :variable:`CMAKE_WARN_DEPRECATED` variable can now be set using the
-  ``-Wdeprecated`` and ``-Wno-deprecated`` :manual:`cmake(1)` options.
+Command-Line
+------------
 
 * The ``-Wdev`` and ``-Wno-dev`` :manual:`cmake(1)` options now also enable
   and suppress the deprecated warnings output by default.
 
-* Warnings about deprecated functionality are now enabled by default.
-  They may be suppressed with ``-Wno-deprecated`` or by setting the
-  :variable:`CMAKE_WARN_DEPRECATED` variable to false.
-
-* Warnings about deprecated functionality can now be controlled in the
-  :manual:`cmake-gui(1)` application.
-
 * The suppression of developer warnings as errors can now be controlled with
   the new ``-Werror=dev`` and ``-Wno-error=dev`` :manual:`cmake(1)` options.
 
+* The :manual:`cmake(1)` ``-E`` command-line tools ``copy``,
+  ``copy_if_different``, ``copy_directory``, and ``make_directory``
+  learned to support multiple input files or directories.
+
+Commands
+--------
+
+* The :command:`cmake_parse_arguments` command is now implemented natively.
