+This document details the changes between this version, readline-6.2,
+and the previous version, readline-6.1.
+
+1.  Changes to Readline
+
+a.  Fixed a bug that caused the unconverted filename to be added to the list of
+    completions when the application specified filename conversion functions.
+
+b.  Fixed a bug that caused the wrong filename to be passed to opendir when the
+    application has specified a filename dequoting function.
+
+c.  Fixed a bug when repeating a character search in vi mode in the case where
+    there was no search to repeat.
+
+d.  When show-all-if-ambiguous is set, the completion routines no longer insert
+    a common match prefix that is shorter than the text being completed.
+
+e.  The full set of vi editing commands may now be used in callback mode.
+
+f.  Fixed a bug that caused readline to not update its idea of the terminal
+    dimensions while running in `no-echo' mode.
+
+h.  Fixed a bug that caused readline to dump core if an application called
+    rl_prep_terminal without setting rl_instream.
+
+i.  Fixed a bug that caused meta-prefixed characters bound to incremental
+    search forward or backward to not be recognized if they were typed
+    subsequently.
+
+j.  The incremental search code treats key sequences that map to the same
+    functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
+
+k.  Fixed a bug in menu-complete that caused it to misbehave with large
+    negative argument.
+
+l.  Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
+    at the end of the line.
+
+m.  Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
+    as if it were a negative argument.
+
+n.  Fixed a bug that caused directory names in words to be completed to not
+    be dequoted correctly.
+
+2.  New Features in Readline
+
+a.  The history library does not try to write the history filename in the
+    current directory if $HOME is unset.  This closes a potential security
+    problem if the application does not specify a history filename.
+
+b.  New bindable variable `completion-display-width' to set the number of
+    columns used when displaying completions.
+
+c.  New bindable variable `completion-case-map' to cause case-insensitive
+    completion to treat `-' and `_' as identical.
+
+d.  There are new bindable vi-mode command names to avoid readline's case-
+    insensitive matching not allowing them to be bound separately.
+
+e.  New bindable variable `menu-complete-display-prefix' causes the menu
+    completion code to display the common prefix of the possible completions
+    before cycling through the list, instead of after.
+
+-------------------------------------------------------------------------------
+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.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-6.0,
+and the previous version, readline-5.2.
+
+1.  Changes to Readline
+
+a.  Fixed a number of redisplay errors in environments supporting multibyte 
+    characters.
+
+b.  Fixed bugs in vi command mode that caused motion commands to inappropriately
+    set the mark.
+
+c.  When using the arrow keys in vi insertion mode, readline allows movement
+    beyond the current end of the line (unlike command mode).
+
+d.  Fixed bugs that caused readline to loop when the terminal has been taken
+    away and reads return -1/EIO.
+
+e.  Fixed bugs in redisplay occurring when displaying prompts containing
+    invisible characters.
+
+f.  Fixed a bug that caused the completion append character to not be reset to
+    the default after an application-specified completion function changed it.
+
+g.  Fixed a problem that caused incorrect positioning of the cursor while in
+    emacs editing mode when moving forward at the end of a line while using
+    a locale supporting multibyte characters.
+
+h.  Fixed an off-by-one error that caused readline to drop every 511th
+    character of buffered input.
+
+i.  Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
+
+j.  Fixed redisplay bugs caused by multiline prompts with invisible characters
+    or no characters following the final newline.
+
+k.  Fixed redisplay bug caused by prompts consisting solely of invisible
+    characters.
+
+l.  Fixed a bug in the code that buffers characters received very quickly in
+    succession which caused characters to be dropped.
+
+m.  Fixed a bug that caused readline to reference uninitialized data structures
+    if it received a SIGWINCH before completing initialzation.
+
+n.  Fixed a bug that caused the vi-mode `last command' to be set incorrectly
+    and therefore unrepeatable.
+
+o.  Fixed a bug that caused readline to disable echoing when it was being used
+    with an output file descriptor that was not a terminal.
+
+p.  Readline now blocks SIGINT while manipulating internal data structures
+    during redisplay.
+
+q.  Fixed a bug in redisplay that caused readline to segfault when pasting a
+    very long line (over 130,000 characters).
+
+r.  Fixed bugs in redisplay when using prompts with no visible printing
+    characters.
+
+s.  Fixed a bug that caused redisplay errors when using prompts with invisible
+    characters and numeric arguments to a command in a multibyte locale.
+
+t.  Fixed a bug that caused redisplay errors when using prompts with invisible
+    characters spanning more than two physical screen lines.
+
+2.  New Features in Readline
+
+a.  A new variable, rl_sort_completion_matches; allows applications to inhibit
+    match list sorting (but beware: some things don't work right if
+    applications do this).
+
+b.  A new variable, rl_completion_invoking_key; allows applications to discover
+    the key that invoked rl_complete or rl_menu_complete.
+
+c.  The functions rl_block_sigint and rl_release_sigint are now public and
+    available to calling applications who want to protect critical sections
+    (like redisplay).
+
+d.  The functions rl_save_state and rl_restore_state are now public and
+    available to calling applications; documented rest of readline's state
+    flag values.
+
+e.  A new user-settable variable, `history-size', allows setting the maximum
+    number of entries in the history list.
+
+f.  There is a new implementation of menu completion, with several improvements
+    over the old; the most notable improvement is a better `completions
+    browsing' mode.
+
+g.  The menu completion code now uses the rl_menu_completion_entry_function
+    variable, allowing applications to provide their own menu completion
+    generators.
+
+h.  There is support for replacing a prefix  of a pathname with a `...' when
+    displaying possible completions.  This is controllable by setting the
+    `completion-prefix-display-length' variable.  Matches with a common prefix
+    longer than this value have the common prefix replaced with `...'.
+
+i.  There is a new `revert-all-at-newline' variable.  If enabled, readline will
+    undo all outstanding changes to all history lines when `accept-line' is
+    executed.
+
+-------------------------------------------------------------------------------
+This document details the changes between this version, readline-5.2,
+and the previous version, readline-5.1.
+
+1.  Changes to Readline
+
+a.  Fixed a problem that caused segmentation faults when using readline in
+    callback mode and typing consecutive DEL characters on an empty line.
+
+b.  Fixed several redisplay problems with multibyte characters, all having to
+    do with the different code paths and variable meanings between single-byte
+    and multibyte character redisplay.
+
+c.  Fixed a problem with key sequence translation when presented with the
+    sequence \M-\C-x.
+
+d.  Fixed a problem that prevented the `a' command in vi mode from being
+    undone and redone properly.
+
+e.  Fixed a problem that prevented empty inserts in vi mode from being undone
+    properly.
+
+f.  Fixed a problem that caused readline to initialize with an incorrect idea
+    of whether or not the terminal can autowrap.
+
+g.  Fixed output of key bindings (like bash `bind -p') to honor the setting of
+    convert-meta and use \e where appropriate.
+
+h.  Changed the default filename completion function to call the filename
+    dequoting function if the directory completion hook isn't set.  This means
+    that any directory completion hooks need to dequote the directory name,
+    since application-specific hooks need to know how the word was quoted,
+    even if no other changes are made.
+
+i.  Fixed a bug with creating the prompt for a non-interactive search string
+    when there are non-printing characters in the primary prompt.
+
+j.  Fixed a bug that caused prompts with invisible characters to be redrawn
+    multiple times in a multibyte locale.
+
+k.  Fixed a bug that could cause the key sequence scanning code to return the
+    wrong function.
+
+l.  Fixed a problem with the callback interface that caused it to fail when
+    using multi-character keyboard macros.
+
+m.  Fixed a bug that could cause a core dump when an edited history entry was
+    re-executed under certain conditions.
+
+n.  Fixed a bug that caused readline to reference freed memory when attmpting
+    to display a portion of the prompt.
+
+o.  Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
+    the prompt and input line multiple times.
+
+p.  Fixed history expansion to not be confused by here-string redirection.
+
+q.  Readline no longer treats read errors by converting them to newlines, as
+    it does with EOF.  This caused partial lines to be returned from readline().
+
+r.  Fixed a redisplay bug that occurred in multibyte-capable locales when the
+    prompt was one character longer than the screen width.
+
+2.  New Features in Readline
+
+a.  Calling applications can now set the keyboard timeout to 0, allowing
+    poll-like behavior.
+
+b.  The value of SYS_INPUTRC (configurable at compilation time) is now used as
+    the default last-ditch startup file.
+
+c.  The history file reading functions now allow windows-like \r\n line
+    terminators.
