+for C code in some situations.  Here is a quick example of how to

+** New way to block and unblock asyncs
+
+In addition to scm_c_call_with_blocked_asyncs you can now also use
+scm_frame_block_asyncs in a 'frame' (see above).  Likewise for
+scm_c_call_with_unblocked_asyncs and scm_frame_unblock_asyncs.
+
+** New way to temporarily set the current input, output or error ports
+
+C code can now use scm_frame_current_<foo>_port in a 'frame' (see
+above).  <foo> is one of "input", "output" or "error".
+
+** New way to temporarily set fluids
+
+C code can now use scm_frame_fluid in a 'frame' (see
+above) to temporarily set the value of a fluid.

 ** New types scm_t_intmax and scm_t_uintmax.
 
 On platforms that have them, these types are identical to intmax_t and
