+policy range check in ``cmMakefile::SetPolicy``.
+Commit with a message such as::
+
+  Add deprecation warnings for policies CMP#### and below
+
+  The OLD behaviors of all policies are deprecated, but only by
+  documentation.  Add an explicit deprecation diagnostic for policies
+  introduced in CMake $OLDVER and below to encourage projects to port
+  away from setting policies to OLD.
+
+Update the ``cmake_policy`` version range generated by ``install(EXPORT)``
+in ``cmExportFileGenerator::GeneratePolicyHeaderCode`` to end at the
+previous release.  We use one release back since we now know all the
+policies added for that version.  Commit with a message such as::
+
+  export: Increase maximum policy version in exported files to $prev
+
+  The files generatd by `install(EXPORT)` and `export()` commands
+  are known to work with policies as of CMake $prev, so enable them
+  in sufficiently new CMake versions.

+:command:`find_program` requires permission to execute but not to read.
+
+In CMake 3.18 and below, the :command:`find_program` command on UNIX
+would find files that are readable without requiring execute permission,
+and would not find files that are executable without read permission.
+In CMake 3.19 and above, ``find_program`` now prefers to require execute
+permission but not read permission.  This policy provides compatibility
+with projects that have not been updated to expect the new behavior.
+
+The ``OLD`` behavior for this policy is for ``find_program`` to require
+read permission but not execute permission.
+The ``NEW`` behavior for this policy is for ``find_program`` to require
+execute permission but not read permission.
+
+This policy was introduced in CMake version 3.19.  CMake version |release|
+warns when the policy is not set and uses ``OLD`` behavior.  Use the
+:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
