 and the previous version, readline-2.2.
 
 1.  Changes to Readline
 
-a.  The `make install' target was corrected so that it did not move the
+a.  The version number is now 4.0, to match the major and minor version
-    newly-installed libreadline.a to libhistory.old
+    numbers on the shared readline and history libraries.  Future
+    releases will maintain the identical numbering.
 
-b.  The `make install' target for the documentation will now install the
+b.  Fixed a typo in the `make install' recipe that copied libreadline.a
-    info files from the source directory if they do not appear in the
+    to libhistory.old right after installing it.
-    build directory, since they are shipped in the readline tar file.
 
-c.  Fixed a problem with redisplay that showed up when the prompt string was
+c.  The readline and history info files are now installed out of the source
-    longer than the screen width and the prompt contained invisible characters.
+    directory if they are not found in the build directory.
 
-d.  Fixed a problem with the paren matching code -- the blink was far too
+d.  The library no longer exports a function named `savestring' -- backwards
-    short (it's specified in microseconds, not milliseconds, Chet!).
+    compatibility be damned.
 
-------------------------------------------------------------------------------
+e.  There is no longer any #ifdef SHELL code in the source files.
+
+f.  Some changes were made to the key binding code to fix memory leaks and
+    better support Win32 systems.
+
+g.  Fixed a silly typo in the paren matching code -- it's microseconds, not
+    milliseconds.
+
+h.  The readline library should be compilable by C++ compilers.
+
+i.  The readline.h public header file now includes function prototypes for
+    all readline functions, and some changes were made to fix errors in the
+    source files uncovered by the use of prototypes.
+
+j.  The maximum numeric argument is now clamped at 1000000.
+
+k.  Fixes to rl_yank_last_arg to make it behave better.
+
+l.  Fixed a bug in the display code that caused core dumps if the prompt
+    string length exceeded 1024 characters.
+
+m.  The menu completion code was fixed to properly insert a single completion
+    if there is only one match.
+
+n.  A bug was fixed that caused the display code to improperly display tabs
+    after newlines.
+
+o.  A fix was made to the completion code in which a typo caused the wrong
+    value to be passed to the function that computed the longest common
+    prefix of the list of matches.
+
+p.  The completion code now checks the value of rl_filename_completion_desired,
+    which is set by application-supplied completion functions to indicate
+    that filename completion is being performed, to decide whether or not to
+    call an application-supplied `ignore completions' function.
+
+q.  Code was added to the history library to catch history substitutions
+    using `&' without a previous history substitution or search having been
+    performed.
+
+
+2.  New Features in Readline
+
+a.  There is a new script, support/shobj-conf, to do system-specific shared
+    object and library configuration.  It generates variables for configure
+    to substitute into makefiles.  The README file provides a detailed
+    explanation of the shared library creation process.
+
+b.  Shared libraries and objects are now built in the `shlib' subdirectory.
+    There is a shlib/Makefile.in to control the build process.  `make shared'
+    from the top-level directory is still the right way to build shared
+    versions of the libraries.
+
+c.  rlconf.h is now installed, so applications can find out which features
+    have been compiled into the installed readline and history libraries.
+
+d.  rlstdc.h is now an installed header file.
+
+e.  Many changes to the signal handling:
+        o Readline now catches SIGQUIT and cleans up the tty before returning;
+        o A new variable, rl_catch_signals, is available to application writers 
+          to indicate to readline whether or not it should install its own
+          signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+          SIGTTIN, and SIGTTOU;
+        o A new variable, rl_catch_sigwinch, is available to application
+          writers to indicate to readline whether or not it should install its
+          own signal handler for SIGWINCH, which will chain to the calling
+          applications's SIGWINCH handler, if one is installed;
+        o There is a new function, rl_free_line_state, for application signal
+          handlers to call to free up the state associated with the current
+          line after receiving a signal;
+        o There is a new function, rl_cleanup_after_signal, to clean up the
+          display and terminal state after receiving a signal;
+        o There is a new function, rl_reset_after_signal, to reinitialize the
+          terminal and display state after an application signal handler
+          returns and readline continues
+
+f.  There is a new function, rl_resize_terminal, to reset readline's idea of
+    the screen size after a SIGWINCH.
+
+g.  New public functions: rl_save_prompt and rl_restore_prompt.  These were
+    previously private functions with a `_' prefix.  These functions are
+    used when an application wants to write a message to the `message area'
+    with rl_message and have the prompt restored correctly when the message
+    is erased.
+
+h.  New function hook: rl_pre_input_hook, called just before readline starts
+    reading input, after initialization.
+
+i.  New function hook: rl_display_matches_hook, called when readline would
+    display the list of completion matches.  The new function
+    rl_display_match_list is what readline uses internally, and is available
+    for use by application functions called via this hook.
+
+j.  New bindable function, delete-char-or-list, like tcsh.
+
+k.  A new variable, rl_erase_empty_line, which, if set by an application using
+    readline, will cause readline to erase, prompt and all, lines on which the
+    only thing typed was a newline.
+
+l.  There is a new script, support/shlib-install, to install and uninstall
+    the shared readline and history libraries.
+
+m.  A new bindable variable, `isearch-terminators', which is a string
+    containing the set of characters that should terminate an incremental
+    search without being executed as a command.
+
+n.  A new bindable function, forward-backward-delete-char.

+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared'.  The shared libraries will be created in the shlib
+subdirectory.
+
+Since shared libraries are not created on all platforms, `make install'
+will not automatically install the shared libraries.  To install them,
+change the current directory to shlib and type `make install'.  Running
+`make install-shared' from the top-level build directory will also work.

+@node Readline Signal Handling
+@section Readline Signal Handling
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his
+terminal, or a network connection being broken.  There is a class of
+signals that can be sent to the process currently reading input from
+the keyboard.  Since Readline changes the terminal attributes when it
+is called, it needs to perform special processing when a signal is
+received to restore the terminal to a sane state, or provide application
+writers with functions to do so manually.
+
+Readline contains an internal signal handler that is installed for a
+number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM},
+@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+@code{readline ()} was called, reset the signal handling to what it was
+before @code{readline ()} was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a @code{SIGINT} is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of @code{rl_free_line_state ()}).
+
+There is an additional Readline signal handler, for @code{SIGWINCH}, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an @code{xterm}).  The Readline @code{SIGWINCH}
+handler updates Readline's internal screen size state, and then calls any
+@code{SIGWINCH} signal handler the calling application has installed. 
+Readline calls the application's @code{SIGWINCH} signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a @code{longjmp} back to a main processing loop), it @emph{must}
+call @code{rl_cleanup_after_signal ()} (described below), to restore the
+terminal state. 
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling @code{readline ()}, not in
+a signal handler, so Readline's internal signal state is not corrupted.
+
+@deftypevar int rl_catch_signals
+If this variable is non-zero, Readline will install signal handlers for
+@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM},
+@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}.
+
+The default value of @code{rl_catch_signals} is 1.
+@end deftypevar

+to handle signals other than those Readline catches (@code{SIGHUP},
+for example),

+and internal state cleanup upon receipt of a signal.
+
+@deftypefun void rl_cleanup_after_signal (void)
+This function will reset the state of the terminal to what it was before
