+
+Changes made since CMake 3.29 include the following.
+
+* On platforms that do not support shared libraries, the :command:`add_library`
+  command now rejects creation of shared libraries instead of automatically
+  converting them to static libraries.  See policy :policy:`CMP0164`.
+
+* The :cpack_gen:`CPack Inno Setup Generator` is now available
+  on non-Windows hosts.
+
+* The :cpack_gen:`CPack NuGet Generator` can now generate dependency groups
+  for framework-specific dependencies. The :variable:`CPACK_NUGET_PACKAGE_TFMS`
+  was added to specify a list of framework TFMs for which groups should be
+  generated.
+
+* The :cpack_gen:`CPack WIX Generator` gained support for WiX Toolset v4.
+  See the :variable:`CPACK_WIX_VERSION` variable.
+
+* The :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands
+  gained a ``TLS_VERSION <min>`` option to specify the minimum TLS
+  version for connections to ``https://`` URLs.
+
+* The :variable:`CMAKE_TLS_VERSION` variable and :envvar:`CMAKE_TLS_VERSION`
+  environment variable were added to specify a default minimum TLS version
+  for connections to ``https://`` URLs by the :command:`file(DOWNLOAD)`
+  and :command:`file(UPLOAD)` commands.
+
+* The :envvar:`CMAKE_TLS_VERIFY` environment variable was added as a fallback
+  to the existing :variable:`CMAKE_TLS_VERIFY` variable.  It specifies
+  whether to verify the server certificate for ``https://`` URLs by default.
+
+* The :module:`ExternalProject` module's :command:`ExternalProject_Add`
+  command gained a ``TLS_VERSION <min>`` option, and support for the
+  :variable:`CMAKE_TLS_VERSION` variable and :envvar:`CMAKE_TLS_VERSION`
+  environment variable, to specify the minimum TLS version for connections
+  to ``https://`` URLs.
+
+* The :command:`ctest_submit` command and :option:`ctest -T Submit <ctest -T>`
+  step gained ``TLSVersion`` and ``TLSVerify`` options to control negotiation
+  with ``https://`` URLs.  See the :variable:`CTEST_TLS_VERSION` and
+  :variable:`CTEST_TLS_VERIFY` variables.
+
+* The :genex:`TARGET_PROPERTY` generator expression learned to evaluate
+  :ref:`custom transitive properties <Custom Transitive Properties>`
+  defined by new :prop_tgt:`TRANSITIVE_COMPILE_PROPERTIES` and
+  :prop_tgt:`TRANSITIVE_LINK_PROPERTIES` target properties.
+
+* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
+  now implements support for the ``cxx_std_26`` and ``cuda_std_26``
+  meta-features to indicate that the compiler mode must be at least C++26.
+  These meta-features were first documented by CMake 3.25, but were not fully
+  implemented.
+
+* The :prop_tgt:`CXX_MODULE_STD` property may be used to control
+  ``import std;`` support for targets.
+
+* The :prop_gbl:`PROPAGATE_TOP_LEVEL_INCLUDES_TO_TRY_COMPILE` global property
+  can be used to propagate :variable:`CMAKE_PROJECT_TOP_LEVEL_INCLUDES` into
+  :command:`try_compile` calls that use the
+  :ref:`whole-project signature <Try Compiling Whole Projects>`.
+  This is primarily intended as a way for dependency providers to be enabled
+  in such :command:`try_compile` calls.
+
+* Calling :command:`FetchContent_Populate` with just the name of a
+  dependency is now deprecated. Projects should call
+  :command:`FetchContent_MakeAvailable` instead. See policy :policy:`CMP0169`.
+  Calling :command:`FetchContent_Populate` with full population details
+  rather than just a dependency name remains fully supported.
+
+* The :command:`enable_language` command now fails with an error
+  if it is called before the first :command:`project` call.
+  See policy :policy:`CMP0165`.
+
+* When :variable:`FETCHCONTENT_FULLY_DISCONNECTED` is set to true,
+  :command:`FetchContent_MakeAvailable` and the single-argument form of
+  :command:`FetchContent_Populate` require that the dependency's source
+  directory has already been populated. CMake 3.29 and earlier did not
+  check this requirement, but it is now enforced, subject to policy
+  :policy:`CMP0170`.
+
+* :module:`FetchContent` now prefers to populate content directly rather
+  than using a separate sub-build. This may significantly improve configure
+  times on some systems (Windows especially, but also on macOS when using
+  the Xcode generator). Policy :policy:`CMP0168` provides backward
+  compatibility for those projects that still rely on using a sub-build for
+  content population.
+
+* The :manual:`cmake-file-api(7)` "cmakeFiles" version 1 object's ``version``
+  field has been updated to 1.1.
+
+* The :manual:`cmake-file-api(7)` "cmakeFiles" version 1 object gained a
+  ``globsDependent`` field to report :command:`file(GLOB)` calls using
+  ``CONFIGURE_DEPENDS``.
+
+* The :module:`FindBacktrace` module now provides an imported target.
+
+* The :module:`FindBLAS` and :module:`FindLAPACK` modules gained
+  support for ``libblastrampoline``.
+
+* The :module:`FindBoost` module has been removed by policy :policy:`CMP0167`.
+  Port projects to upstream Boost's ``BoostConfig.cmake`` package
+  configuration file, for which ``find_package(Boost)`` now searches.
+
+* The :module:`FindCUDAToolkit` module now provides a target for
+  ``libnvfatbin`` and ``libnvfatbin_static``, if found.
+
+* The :module:`FindCUDAToolkit` module now searches the
+  :variable:`CMAKE_CUDA_COMPILER <CMAKE_<LANG>_COMPILER>` and
+  the environment variable :envvar:`CUDACXX` even when the CUDA
+  language isn't enabled.
+
+* The :module:`FindOpenMP` module gained a ``OpenMP_RUNTIME_MSVC``
+  option to control the OpenMP runtime used with MSVC.
+
+* The :module:`FindPython`, :module:`FindPython2` and :module:`FindPython3`
+  modules offer, on ``Windows`` platform, a better support of the ``Python``
+  debug version:
+
+  * new variables:
+
+    * ``Python_EXECUTABLE_DEBUG``
+    * ``Python_INTERPRETER``
+    * ``Python_DEBUG_POSTFIX``
+
+  * new targets:
+
+    * ``Python::InterpreterDebug``
+    * ``Python::InterpreterMultiConfig``
+
+  And the ``python_add_library()`` command manage the :prop_tgt:`DEBUG_POSTFIX`
+  target property based on the value of the ``Python_DEBUG_POSTFIX`` variable.
+
+* The :module:`FindPython`, :module:`FindPython3` modules gained the support
+  of the free threaded python version.
+
+* Generator expressions ``$<<LANG>_COMPILER_FRONTEND_VARIANT:...>`` were added that allow
+  access to the value of the associated :variable:`CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT`
+  variables.
+
+* Link features, as used with the :genex:`LINK_LIBRARY` generator expression,
+  gained the ability to have properties that describe their behavior by
+  specifying the :variable:`CMAKE_LINK_LIBRARY_<FEATURE>_PROPERTIES` or
+  :variable:`CMAKE_<LANG>_LINK_LIBRARY_<FEATURE>_PROPERTIES` variables.
+
+* The :genex:`TARGET_PROPERTY` generator expression now evaluates target
+  properties :prop_tgt:`INTERFACE_LINK_OPTIONS`,
+  :prop_tgt:`INTERFACE_LINK_DIRECTORIES`, and
+  :prop_tgt:`INTERFACE_LINK_DEPENDS` correctly by following private
+  dependencies of static libraries.  See policy :policy:`CMP0166`.
+
+* The :genex:`$<QUOTE>` generator expression was added to evaluate to ``"``.
+
+* The :variable:`CMAKE_<LANG>_STANDARD_LATEST` variable was added to
+  describe the latest supported standard of language ``<LANG>``.
+
+* :manual:`cmake-presets(7)` files now support schema version ``9``:
+
+  * ``include`` fields now expand all macros except ``$env{}`` and
+    preset-specific macros.
+
+* The durations printed after "Configuring done" and "Generating done"
+  messages now reflect time spent in generator-specific steps, and
+  in a code model evaluation step at the beginning of generation that
+  was not previously captured.  Printed durations may appear longer
+  than in previous versions of CMake.
+
+* The :prop_sf:`GENERATED` source file property is now visible in all
+  directories.  See policy :policy:`CMP0163`.  Policy :policy:`CMP0118`'s
+  documentation has been revised to describe its actual effects.
+
+* The precompiled Windows ``.msi`` installers provided on
+  `cmake.org <https://cmake.org/download/>`_, when performing a fresh
+  installation, now modify the system-wide ``PATH`` by default.
+  When replacing an existing installation, the ``PATH`` modification
+  preference is preserved by default.
+
+* The official ``.zip`` source archive provided on
+  `cmake.org <https://cmake.org/download/>`_ now uses LF newlines,
+  instead of CRLF newlines, for consistency with modern conventions.
+
+* The :generator:`Visual Studio 9 2008` generator has been removed.
+
+* A :prop_tgt:`VS_FILTER_PROPS` target property was added to tell
+  :ref:`Visual Studio Generators` for VS 2010 and above to use a
+  custom MSBuild filter ``.props`` file.
+
+* :ref:`Visual Studio Generators` now add ``UseDebugLibraries`` indicators to
+  ``.vcxproj`` files to denote which configurations are debug configurations.
+  See policy :policy:`CMP0162`.
+
+* The :variable:`CMAKE_VS_USE_DEBUG_LIBRARIES` variable and corresponding
+  :prop_tgt:`VS_USE_DEBUG_LIBRARIES` target property were added to explicitly
+  control ``UseDebugLibraries`` indicators in ``.vcxproj`` files.
