+3.29.5
+------
+
+* The :cpack_gen:`CPack WIX Generator`'s :variable:`CPACK_WIX_INSTALL_SCOPE`
+  variable, new in 3.29, now defaults to ``NONE``.  This restores
+  compatibility with behavior of 3.28 and below: without a custom WiX
+  template, it produces installers that only create start menu and
+  uninstall entries for the current user, even though they install
+  for all users.
+
+  In 3.29.0 through 3.29.4, ``CPACK_WIX_INSTALL_SCOPE`` defaulted to
+  ``perMachine``.  This created MSI installers that create start menu
+  and uninstall entries for all users by default.  While this behavior
+  is better on its own, these installers do not cleanly replace existing
+  installations created with MSI installers produced by 3.28 and below.
+  3.29.5 reverts the default for compatibility.  Projects may transition
+  to ``perMachine`` on their own schedule by setting
+  ``CPACK_WIX_INSTALL_SCOPE``.
