+When building Python on macOS from source, ``_tkinter`` now links with
+non-system Tcl and Tk frameworks if they are installed in
+``/Library/Frameworks``, as had been the case on older releases
+of macOS. If a macOS SDK is explicitly configured, by using
+``--enable-universalsdk=`` or ``-isysroot``, only the SDK itself is
+searched. The default behavior can still be overridden with
+``--with-tcltk-includes`` and ``--with-tcltk-libs``.
