+  Portability: dreadful hack to track down the real locations
+  of signal.h to find signal names.  rc now builds under CygWin32!
+
+  Portability: replace above dreadful hack with mksignal.c, contributed
+  by Vincent Broman.
+
+  Portability: use POSIX wait() macros (WIFEXITED and friends).
+  Unfortunately, POSIX omitted to supply WIFDUMPED, so this doesn't buy a
+  great deal.
+
+  Distribution: remove the dependencies of y.tab.[ch] on parse.y from Makefile.am.
+  The justification for this is that, unless you're hacking on rc's grammar, there's
+  no reason to use anything other than the distributed files (which were generated
+  with byacc and very lightly edited to silence a few gcc warnings).
+
+  Enhancement: the example in addon.c wasn't very useful, since it
+  depended on files which weren't included with the distribution.  There
+  is now a working, if trivial, example.
+
+  Tidiness: the code was compiled with as many gcc warnings enabled as
+  I could find.  Very few problems turned up.  Some unused function
+  arguments were removed.  Where unused arguments could not be removed
+  (because the function is one of a set that must all have the same
+  prototype), they were renamed to `ignore'.
+
+  Portability: some versions of readline define the name `Function',
+  which rc also uses.  Its use in rc has been renamed to `rc_Function'.
+
+  Documentation: the `history' man page didn't explain what end of line
+  does in editing mode.  It now does.
+
+  Bug: the interaction with readline was broken, particularly with
+  respect to signal handling.  I've incorporated some changes from Tom
+  Culliton which should sort this out.  Unfortunately, we now have 3 different
+  code paths for readline 2.1, readline 2.2, and editline :-(.
+
+  Configuration: if you say `--with-readline' or `--with-editline' it is now an
+  error if the appropriate library is not found.
