+CMake 3.18 Release Notes
+************************
+
+.. only:: html
+
+  .. contents::
+
+Changes made since CMake 3.17 include the following.
+
+* :command:`add_library` and :command:`add_executable` gain the capability
+  to create an ``ALIAS`` to
+  non-``GLOBAL`` :ref:`Imported Target <Imported Targets>`.
+
+* Creation of an ``ALIAS`` target overwriting an existing target now raise an
+  error. See policy :policy:`CMP0107`.
+
+* :manual:`ccmake(1)` learned to read a :envvar:`CCMAKE_COLORS`
+  environment variable to customize colors.
+
+* New :module:`CheckLinkerFlag` module has been added to provide a facility to
+  check validity of link flags.
+
+* :manual:`cmake-gui(1)` now populates its generator selection
+  widget default value from the :envvar:`CMAKE_GENERATOR` environment
+  variable.  Additionally, environment variables
+  :envvar:`CMAKE_GENERATOR_PLATFORM` and :envvar:`CMAKE_GENERATOR_TOOLSET`
+  are used to populate their respective widget defaults.
+
+* The :command:`cmake_language()` command was added for meta-operations on
+  scripted or built-in commands, starting with a mode to ``CALL`` other
+  commands, and ``EVAL CODE`` to inplace evaluate a CMake script.
+* :manual:`cmake(1)` gained a ``cat`` command line
+  option that can be used to concatenate files and print them
+  on standard output.
+
+* The :cpack_gen:`CPack RPM Generator` gained
+  :variable:`CPACK_RPM_PRE_TRANS_SCRIPT_FILE`
+  :variable:`CPACK_RPM_POST_TRANS_SCRIPT_FILE`
+  variables to specify pre- and post-trans scripts.
+
+* The :module:`CTestCoverageCollectGCOV` module
+  :command:`ctest_coverage_collect_gcov` function gained a
+  ``TARBALL_COMPRESSION`` option to control compression of the
+  tarball of collected results.
+
+* :manual:`ctest(1)` now logs environment variables that it sets for each test,
+  either due to the :prop_test:`ENVIRONMENT` property or the
+  :ref:`resource allocation <ctest-resource-allocation>` feature, and submits
+  this log to CDash. It does not log environment variables that were set
+  outside of CTest.
+
+* :manual:`ctest(1)` gained a new :variable:`CTEST_RESOURCE_SPEC_FILE`
+  variable, which can be used to specify a
+  :ref:`resource specification file <ctest-resource-specification-file>`.
+
+* :manual:`ctest(1)` gained a ``--stop-on-failure`` option,
+  which can be used to stop running the tests once one has failed.
+
+* The :command:`ctest_test` command gained a ``STOP_ON_FAILURE`` option
+  which can be used to stop running the tests once one has failed.
+
+* :variable:`CMAKE_CUDA_ARCHITECTURES` is now initialized when
+  :variable:`CMAKE_CUDA_COMPILER_ID <CMAKE_<LANG>_COMPILER_ID>` is ``NVIDIA``.
+  Empty :prop_tgt:`CUDA_ARCHITECTURES` raises an error. See policy
+  :policy:`CMP0104`.
+
+* Added :prop_tgt:`CUDA_ARCHITECTURES` target property for specifying CUDA
+  output architectures. Users are encouraged to use this instead of specifying
+  options manually, as this approach is compiler-agnostic.
+
+* The ``CUDA`` language now supports Clang as a compiler.
+
+* When building CMake itself from source and not using a system-provided
+  libcurl, HTTP/2 support is now enabled for commands supporting
+  network communication via ``http(s)``, such as :command:`file(DOWNLOAD)`,

+  The precompiled binaries provided on ``cmake.org`` now support HTTP/2.
+
+* The :module:`Documentation` module has been deprecated via
+  :policy:`CMP0106`. This module was essentially VTK code that CMake should
+  not be shipping anymore.
+
+* An explicit deprecation diagnostic was added for policy ``CMP0070``
+  and policy ``CMP0071`` (``CMP0069`` 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 :prop_tgt:`LINK_OPTIONS` and :prop_tgt:`INTERFACE_LINK_OPTIONS` target
+  properties are now used for the device link step. See policy :policy:`CMP0105`.
+
+* The :command:`execute_process` command gained the ``ECHO_OUTPUT_VARIABLE``
+  and ``ECHO_ERROR_VARIABLE`` options.
+
+* The :command:`export` command now raise an error if used multiple times with
+  same ``FILE`` without ``APPEND``. See policy :policy:`CMP0103`.
+
+* The :command:`ExternalProject_Add` command gained a new
+  ``GIT_REMOTE_UPDATE_STRATEGY`` keyword.  This can be used to specify how
+  failed rebase operations during a git update should be handled.
+  The ``CMAKE_EP_GIT_REMOTE_UPDATE_STRATEGY`` variable was also added as a
+  global default and is honored by both the :module:`ExternalProject` and
+  :module:`FetchContent` modules.
+
+* The :command:`FetchContent_Declare` command now supports a ``SOURCE_SUBDIR``
+  option.  It can be used to direct :command:`FetchContent_MakeAvailable`
+  to look in a different location for the ``CMakeLists.txt`` file.
+
+* The :command:`file` command gained the ``ARCHIVE_{CREATE|EXTRACT}`` subcommands.
+
+  These subcommands will replicate the :manual:`cmake(1)` ``-E tar`` functionality in
+  CMake scripting code.
+
+* The :command:`file(CONFIGURE)` subcommand was created in order replicate the
+  :command:`configure_file` functionality without resorting to a pre-existing
+  file on disk as input. The content is instead passed as a string.
+
+* The :command:`file(UPLOAD)` command gained ``TLS_VERIFY`` and ``TLS_CAINFO``
+  options to control server certificate verification.
+
+* The :module:`FindBLAS` module now provides an imported target.

+  modules support now the ``IronPython`` implementation on all platforms.
+
+* The :module:`FindPython3`, :module:`FindPython2` and :module:`FindPython`
+  modules gained the capability to handle ``PyPy`` product.
+
+* The :module:`FindRuby` module input and output variables were all renamed
+  from ``RUBY_`` to ``Ruby_`` for consistency with other find modules.
+  Input variables of the old case will be honored if provided, and output
+  variables of the old case are always provided.
+
+* The :module:`FindSWIG` module now accepts target languages as  ``COMPONENTS``
+  and ``OPTIONAL_COMPONENTS`` arguments to ``find_package``.

+* The :prop_tgt:`Fortran_PREPROCESS` target property and
+  :prop_sf:`Fortran_PREPROCESS` source-file property were added to
+  control preprocessing of Fortran source files.
+
+* The :module:`FindPackageHandleStandardArgs` module option ``REQUIRED_VARS``
+  is now optional if ``HANDLE_COMPONENTS`` is specified.
+
+* The :prop_tgt:`FRAMEWORK_MULTI_CONFIG_POSTFIX_<CONFIG>` target property
+  and associated :variable:`CMAKE_FRAMEWORK_MULTI_CONFIG_POSTFIX_<CONFIG>`
+  variable were created to allow adding a postfix to the name of a
+  framework file name when using a multi-config generator.
+
+* To manage device and host link steps, the ``$<DEVICE_LINK:...>`` and
+  ``$<HOST_LINK:...>``
+  :manual:`generator expressions <cmake-generator-expressions(7)>` were added.
+
+* The ``$<LINK_LANGUAGE:...>`` and ``$<LINK_LANG_AND_ID:...>``

+
+* Add support for profiling of CMake scripts through the parameters
+  ``--profiling-output`` and ``--profiling-format``. These options can
+  be used by users to gain insight into the performance of their scripts.
+
+  The first supported output format is ``google-trace`` which is a format
+  supported by Google Chrome's ``about:tracing`` tab.
+
+* The :command:`find_program`, :command:`find_library`, :command:`find_path`
+  and :command:`find_file` commands gained a new ``REQUIRED`` option that will
+  stop processing with an error message if nothing is found.
