+* Changes to the stand-alone interpreter
+
+** New options interface: readline-options,
+readline-enable, readline-disable, readline-set!
+
+** Command line history is now restored from and saved to file
+
+If readline is used and the readline option `history-file' is enabled,
+the command line history is read from file when the interpreter is
+entered, and written to file on exit. The filename used can be
+specified with the environment variable GUILE_HISTORY. Default file
+name is "$HOME/.guile_history". Nothing special happens if errors
+occur during read or write.
+
+** Command line history length can now be customized.
+Command line history length is now controlled by the readline option
+`history-length'. Default is 200 lines.
+
+** All builtins now print as primitives.
+Previously builtin procedures not belonging to the fundamental subr
+types printed as #<compiled closure #<primitive-procedure gsubr-apply>>.
+Now, they print as #<primitive-procedure NAME>.
+
+** Backtraces slightly more intelligible.
+gsubr-apply and macro transformer application frames no longer appear
+in backtraces.
