This document details the changes between this version, readline-6.1,
and the previous version, readline-6.0.

1.  Changes to Readline

a.  The SIGWINCH signal handler now avoids calling the redisplay code if
    one arrives while in the middle of redisplay.

b.  Changes to the timeout code to make sure that timeout values greater
    than one second are handled better.

c.  Fixed a bug in the redisplay code that was triggered by a prompt
    containing invisible characters exactly the width of the screen.

d.  Fixed a bug in the redisplay code encountered when running in horizontal
    scroll mode.

e.  Fixed a bug that prevented menu completion from properly completing
    filenames.

f.  Fixed a redisplay bug caused by a multibyte character causing a line to
    wrap.

g.  Fixed a bug that caused key sequences of two characters to not be
    recognized when a longer sequence identical in the first two characters
    was bound.

h.  Fixed a bug that caused history expansion to be attempted on $'...'
    single-quoted strings.

i.  Fixed a bug that caused incorrect redisplay when the prompt contained
    multibyte characters in an `invisible' sequence bracketed by \[ and
    \].

j.  Fixed a bug that caused history expansion to short-circuit after
    encountering a multibyte character.

k.  Fixed a bug that caused applications using the callback interface to not
    react to SIGINT (or other signals) until another character arrived.

2.  New Features in Readline

a.  New bindable function: menu-complete-backward.

b.  In the vi insertion keymap, C-n is now bound to menu-complete by default,
    and C-p to menu-complete-backward.

c.  When in vi command mode, repeatedly hitting ESC now does nothing, even
    when ESC introduces a bound key sequence.  This is closer to how
    historical vi behaves.

d.  New bindable function: skip-csi-sequence.  Can be used as a default to
    consume key sequences generated by keys like Home and End without having
    to bind all keys.

e.  New application-settable function: rl_filename_rewrite_hook.  Can be used
    to rewite or modify filenames read from the file system before they are
    compared to the word to be completed.

f.  New bindable variable: skip-completed-text, active when completing in the
    middle of a word.  If enabled, it means that characters in the completion
    that match characters in the remainder of the word are "skipped" rather
    than inserted into the line.

g.  The pre-readline-6.0 version of menu completion is available as
    "old-menu-complete" for users who do not like the readline-6.0 version.

h.  New bindable variable: echo-control-characters.  If enabled, and the
    tty ECHOCTL bit is set, controls the echoing of characters corresponding
    to keyboard-generated signals.

i.  New bindable variable: enable-meta-key.  Controls whether or not readline
    sends the smm/rmm sequences if the terminal indicates it has a meta key
    that enables eight-bit characters.
