+This document details the changes between this version, readline-2.2,
+and the previous version, readline-2.1.
+
+1.  Changes to Readline
+
+a.  Added a missing `extern' to a declaration in readline.h that kept
+    readline from compiling cleanly on some systems.
+
+b.  The history file is now opened with mode 0600 when it is written for
+    better security.
+
+c.  Changes were made to the SIGWINCH handling code so that prompt redisplay
+    is done better.
+
+d.  ^G now interrupts incremental searches correctly.
+
+e.  A bug that caused a core dump when the set of characters to be quoted
+    when completing words was empty was fixed.
+
+f.  Fixed a problem in the readline test program rltest.c that caused a core
+    dump.
+
+g.  The code that handles parser directives in inputrc files now displays
+    more error messages.
+
+h.  The history expansion code was fixed so that the appearance of the
+    history comment character at the beginning of a word inhibits history
+    expansion for that word and the rest of the input line.
+
+i.  The code that prints completion listings now behaves better if one or
+    more of the filenames contains non-printable characters.
+
+j.  The time delay when showing matching parentheses is now 0.5 seconds.
+
+
+2.  New Features in Readline
+
+a.  There is now an option for `iterative' yank-last-arg handline, so a user
+    can keep entering `M-.', yanking the last argument of successive history
+    lines.
+
+b.  New variable, `print-completions-horizontally', which causes completion
+    matches to be displayed across the screen (like `ls -x') rather than up
+    and down the screen (like `ls').
+
+c.  New variable, `completion-ignore-case', which causes filename completion
+    and matching to be performed case-insensitively.
+
+d.  There is a new bindable command, `magic-space', which causes history
+    expansion to be performed on the current readline buffer and a space to
+    be inserted into the result.
+
+e.  There is a new bindable command, `menu-complete', which enables tcsh-like
+    menu completion (successive executions of menu-complete insert a single
+    completion match, cycling through the list of possible completions).
+
+f.  There is a new bindable command, `paste-from-clipboard', for use on Win32
+    systems, to insert the text from the Win32 clipboard into the editing
+    buffer.
+
+g.  The key sequence translation code now understands printf-style backslash
+    escape sequences, including \NNN octal escapes.  These escape sequences
+    may be used in key sequence definitions or macro values.
+
+h.  An `$include' inputrc file parser directive has been added.

+Bash provides two builtin commands that allow you to manipulate the

+@table @code
+
+@item fc
+@btindex fc
+@example
+@code{fc [-e @var{ename}] [-nlr] [@var{first}] [@var{last}]}
+@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
+@end example
+
+Fix Command.  In the first form, a range of commands from @var{first} to
+@var{last} is selected from the history list.  Both @var{first} and
+@var{last} may be specified as a string (to locate the most recent
+command beginning with that string) or as a number (an index into the
+history list, where a negative number is used as an offset from the
+current command number).  If @var{last} is not specified it is set to
+@var{first}.  If @var{first} is not specified it is set to the previous
+command for editing and @minus{}16 for listing.  If the @samp{-l} flag is
+given, the commands are listed on standard output.  The @samp{-n} flag
+suppresses the command numbers when listing.  The @samp{-r} flag
+reverses the order of the listing.  Otherwise, the editor given by
+@var{ename} is invoked on a file containing those commands.  If
+@var{ename} is not given, the value of the following variable expansion
+is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.  This says to use the
+value of the @code{FCEDIT} variable if set, or the value of the
+@code{EDITOR} variable if that is set, or @code{vi} if neither is set.
+When editing is complete, the edited commands are echoed and executed.
+
+In the second form, @var{command} is re-executed after each instance
+of @var{pat} in the selected command is replaced by @var{rep}.
+
+A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
+that typing @samp{r cc} runs the last command beginning with @code{cc}
+and typing @samp{r} re-executes the last command (@pxref{Aliases}).

+@end example
+
+Display the history list with line numbers.  Lines prefixed with
+with a @samp{*} have been modified.  An argument of @var{n} says
+to list only the last @var{n} lines.  Options, if supplied, have
+the following meanings:
+
+@table @code
+@item -w
+Write out the current history to the history file.
+
+@item -r
+Read the current history file and append its contents to
+the history list.
+
+@item -a
+Append the new
+history lines (history lines entered since the beginning of the
+current Bash session) to the history file.
+
+@item -n
+Append the history lines not already read from the history file
+to the current history list.  These are lines appended to the history
+file since the beginning of the current Bash session.
+
+@item -c
+Clear the history list.  This may be combined
+with the other options to replace the history list completely.
+
+@item -s
+The @var{arg}s are added to the end of
+the history list as a single entry.
+
+@item -p
+Perform history substitution on the @var{arg}s and display the result
+on the standard output, without storing the results in the history list.
+@end table
+
+When the @samp{-w}, @samp{-r}, @samp{-a}, or @samp{-n} option is
+used, if @var{filename}
+is given, then it is used as the history file.  If not, then
+the value of the @code{HISTFILE} variable is used.
