-This document details the changes between this version, readline-6.3, and the
-previous version, readline-6.2.
-
-1. Changes to Readline
-
-a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
- commands to work on the entire line.
-
-b. Fixed a bug that caused redisplay problems with prompts longer than 128
- characters and history searches.
-
-c. Fixed a bug that caused readline to try and run code to modify its idea
- of the screen size in a signal handler context upon receiving a SIGWINCH.
-
-d. Fixed a bug that caused the `meta' key to be enabled beyond the duration
- of an individual call top readline().
-
-e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's
- redisplay to mishandle zero-width combining characters.
-
-f. Fixed a bug that caused readline to `forget' part of a key sequence when
- a multiple-key sequence caused it to break out of an incremental search.
-
-g. Fixed bugs that caused readline to execute code in a signal handler
- context if interrupted while reading from the file system during completion.
-
-h. Fixed a bug that caused readline to `forget' part of a key sequence when
- reading an unbound multi-character key sequence.
-
-i. Fixed a bug that caused Readline's signal handlers to be installed beyond
- the bounds of a single call to readline().
-
-j. Fixed a bug that caused the `.' command to not redo the most recent `R'
- command in vi mode.
-
-k. Fixed a bug that caused ignoring case in completion matches to result in
- readline using the wrong match.
-
-l. Paren matching now works in vi insert mode.
-
-m. Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
- work together.
-
-n. Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone
- in vi editing mode.
-
-o. Fixed a bug that caused the filename comparison code to not compare
- multibyte characters correctly when using case-sensitive or case-mapping
- comparisons.
-
-p. Fixed the input reading loop to call the input hook function only when there
- is no terminal input available.
-
-q. Fixed a bug that caused binding a macro to a multi-character key sequence
- where the sequence and macro value share a common prefix to not perform
- the macro replacement.
-
-r. Fixed several redisplay errors with multibyte characters and prompts
- containing invisible characters when using horizontal scrolling.
-
-s. Fixed a bug that caused redisplay errors when trying to overwrite
- existing characters using multibyte characters.
-
-t. Fixed a bug in vi mode that caused the arrow keys to set the saved last
- vi-mode command to the wrong value.
-
-u. Fixed a bug that caused double-quoted strings to be scanned incorrectly
- when being used as the value of a readline variable assignment.
-
-v. Fixed a bug with vi mode that prevented `.' from repeating a command
- entered on a previous line (command).
-
-w. Fixed a bug that could cause completion to core dump if it was interrupted
- by a signal.
-
-2. New Features in Readline
-
-a. Readline is now more responsive to SIGHUP and other fatal signals when
- reading input from the terminal or performing word completion but no
- longer attempts to run any not-allowable functions from a signal handler
- context.
-
-b. There are new bindable commands to search the history for the string of
- characters between the beginning of the line and the point
- (history-substring-search-forward, history-substring-search-backward)
-
-c. Readline allows quoted strings as the values of variables when setting
- them with `set'. As a side effect, trailing spaces and tabs are ignored
- when setting a string variable's value.
-
-d. The history library creates a backup of the history file when writing it
- and restores the backup on a write error.
-
-e. New application-settable variable: rl_filename_stat_hook: a function called
- with a filename before using it in a call to stat(2). Bash uses it to
- expand shell variables so things like $HOME/Downloads have a slash
- appended.
-
-f. New bindable function `print-last-kbd-macro', prints the most-recently-
- defined keyboard macro in a reusable format.
-
-g. New user-settable variable `colored-stats', enables use of colored text
- to denote file types when displaying possible completions (colored analog
- of visible-stats).
-
-h. New user-settable variable `keyseq-timout', acts as an inter-character
- timeout when reading input or incremental search strings.
-
-i. New application-callable function: rl_clear_history. Clears the history list
- and frees all readline-associated private data.
-
-j. New user-settable variable, show-mode-in-prompt, adds a characters to the
- beginning of the prompt indicating the current editing mode.
-
-k. New application-settable variable: rl_input_available_hook; function to be
- called when readline detects there is data available on its input file
- descriptor.
-
-l. Readline calls an application-set event hook (rl_signal_event_hook) after
- it gets a signal while reading input (read returns -1/EINTR but readline
- does not handle the signal immediately) to allow the application to handle
- or otherwise note it. Not currently called for SIGHUP or SIGTERM.
-
-m. If the user-settable variable `history-size' is set to a value less than
- 0, the history list size is unlimited.

-This document details the changes between this version, readline-7.0, and the
-previous version, readline-6.3.
-
-1. Changes to Readline
-
-a. A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y'
- commands with modifiers was fixed.
-
-b. Fixed a bug that caused callback mode to dump core when reading a
- multiple-key sequence (e.g., arrow keys).
-
-c. Fixed a bug that caused the redisplay code to erase some of the line when
- using horizontal scrolling with incremental search.
-
-d. Readline's input handler now performs signal processing if read(2) is
- interrupted by SIGALRM or SIGVTALRM.
-
-e. Fixed a problem with revert-all-at-newline freeing freed memory.
-
-f. Clarified the documentation for the history_quotes_inhibit_expansion
- variable to note that it inhibits scanning for the history comment
- character and that it only affects double-quoted strings.
-
-g. Fixed an off-by-one error in the prompt printed when performing searches.
-
-h. Use pselect(2), if available, to wait for input before calling read(2), so
- a SIGWINCH can interrupt it, since it doesn't interrupt read(2).
-
-i. Some memory leaks caused by signals interrupting filename completion have
- been fixed.
-
-j. Reading EOF twice on a non-empty line causes EOF to be returned, rather
- than the partial line. This can cause partial lines to be executed on
- SIGHUP, for example.
-
-k. Fixed a bug concerning deleting multibyte characters from the search
- string while performing an incremental search.
-
-l. Fixed a bug with tilde expanding directory names in filename completion.
-
-m. Fixed a bug that did not allow binding sequences beginning with a `\'.
-
-n. Fixed a redisplay bug involving incorrect line wrapping when the prompt
- contains a multibyte character in the last screen column.
-
-o. Fixed a bug that caused history expansion to disregard characters that are
- documented to delimit a history event specifier without requiring `:'.
-
-p. Fixed a bug that could cause reading past the end of a string when reading
- the value when binding the set of isearch terminators.
-
-q. Fixed a bug that caused readline commands that depend on knowing which
- key invoked them to misbehave when dispatching key sequences that are
- prefixes of other key bindings.
-
-r. Paren matching now works in vi insert mode.
-
-s. Colored completion prefixes are now displayed using a different color, less
- likely to collide with files.
-
-t. Fixed a bug that caused vi-mode character search to misbehave when
- running in callback mode.
-
-u. Fixed a bug that caused output to be delayed when input is coming from a
- macro in vi-mode.
-
-v. Fixed a bug that caused the vi-mode `.' command to misbehave when redoing
- a multi-key key sequence via a macro.
-
-w. Fixed a bug that caused problems with applications that supply their own
- input function when performing completion.
-
-x. When read returns -1/EIO when attempting to read a key, return an error
- instead of line termination back to the caller.
-
-y. Updated tty auditing feature based on patch from Red Hat.
-
-z. Fixed a bug that could cause the history library to crash on overflows
- introduced by malicious editing of timestamps in the history file.
-
-aa. The history file writing functions only attempt to create and use a backup
- history file if the history file exists and is a regular file.
-
-bb. Fixed an out-of-bounds read in readline's internal tilde expansion interface.
-
-cc. Fixed several redisplay bugs with prompt strings containing multibyte
- and non-visible characters whose physical length is longer than the screen
- width.
-
-dd. Fixed a redisplay bug with prompt strings containing invisible characters
- whose physical length exceeds the screen width and using incremental search.
-
-ee. Readline prints more descriptive error messages when it encounters errors
- while reading an inputrc file.
-
-ff. Fixed a bug in the character insertion code that attempts to optimize
- typeahead when it reads a character that is not bound to self-insert and
- resets the key sequence state.
-
-gg. When refreshing the line as the result of a key sequence, Readline attempts
- to redraw only the last line of a multiline prompt.
-
-hh. Fixed an issue that caused completion of git commands to display
- incorrectly when using colored-completion-prefix.
-
-ii. Fixed several redisplay bugs having to do with multibyte characters and
- invisible characters in prompt strings.
-
-jj. Fixed a bug that caused mode strings to be displayed incorrectly if the
- prompt was shorter than the mode string.
-
-2. New Features in Readline
-
-a. The history truncation code now uses the same error recovery mechansim as
- the history writing code, and restores the old version of the history file
- on error. The error recovery mechanism handles symlinked history files.
-
-b. There is a new bindable variable, `enable-bracketed-paste', which enables
- support for a terminal's bracketed paste mode.
-
-c. The editing mode indicators can now be strings and are user-settable
- (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
- variables). Mode strings can contain invisible character sequences.
- Setting mode strings to null strings restores the defaults.
-
-d. Prompt expansion adds the mode string to the last line of a multi-line
- prompt (one with embedded newlines).
-
-e. There is a new bindable variable, `colored-completion-prefix', which, if
- set, causes the common prefix of a set of possible completions to be
- displayed in color.
-
-f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
- mode yank-pop.
-
-g. The redisplay code underwent several efficiency improvements for multibyte
- locales.
-
-h. The insert-char function attempts to batch-insert all pending typeahead
- that maps to self-insert, as long as it is coming from the terminal.
-
-i. rl_callback_sigcleanup: a new application function that can clean up and
- unset any state set by readline's callback mode. Intended to be used
- after a signal.
-
-j. If an incremental search string has its last character removed with DEL, the
- resulting empty search string no longer matches the previous line.
-
-k. If readline reads a history file that begins with `#' (or the value of
- the history comment character) and has enabled history timestamps, the history
- entries are assumed to be delimited by timestamps. This allows multi-line
- history entries.
-
-l. Readline now throws an error if it parses a key binding without a terminating
- `:' or whitespace.
-
-
-m. The default binding for ^W in vi mode now uses word boundaries specified
- by Posix (vi-unix-word-rubout is bindable command name).
-
-n. rl_clear_visible_line: new application-callable function; clears all
- screen lines occupied by the current visible readline line.
-
-o. rl_tty_set_echoing: application-callable function that controls whether
- or not readline thinks it is echoing terminal output.
-
-p. Handle >| and strings of digits preceding and following redirection
- specifications as single tokens when tokenizing the line for history
- expansion.
-
-q. Fixed a bug with displaying completions when the prefix display length
- is greater than the length of the completions to be displayed.
-
-r. The :p history modifier now applies to the entire line, so any expansion
- specifying :p causes the line to be printed instead of expanded.
-
-s. New application-callable function: rl_pending_signal(): returns the signal
- number of any signal readline has caught but not yet handled.
-
-t. New application-settable variable: rl_persistent_signal_handlers: if set
- to a non-zero value, readline will enable the readline-6.2 signal handler
- behavior in callback mode: handlers are installed when
- rl_callback_handler_install is called and removed removed when a complete
- line has been read.
set incorrectly. This prevents yank-last-arg from working as intended, for
example.
+t. Make sure that all undo groups are closed when leaving vi insertion mode.
+
+u. Make sure that the vi-mode `C' and `c' commands enter insert mode even if
+ the motion command doesn't have any effect.
+
+v. Fixed several potential memory leaks in the callback mode context handling.
+
+w. If readline is handling a SIGTTOU, make sure SIGTTOU is blocked while
+ executing the terminal cleanup code, since it's no longer run in a signal
+ handling context.
+
+x. Fixed a bug that could cause an application with an application-specific
+ redisplay function to crash if the line data structures had not been
+ initialized.
+
+y. Terminals that are named "dumb" or unknown do not enable bracketed paste
+ by default.
+
+z. Ensure that disabling bracketed paste turns off highlighting the incremental
+ search string when the search is successful.

2. New Features in Readline
a. If a second consecutive completion attempt produces matches where the first
g. Readline sets the mark in several additional commands.
-h. Bracketed paste mode is enabled by default (for now).
+h. Bracketed paste mode is enabled by default. There is a configure-time
+ option (--enable-bracketed-paste-default) to set the default to on or off.
i. Readline tries to take advantage of the more regular structure of UTF-8
characters to identify the beginning and end of characters when moving
j. The bindable operate-and-get-next command (and its default bindings) are
now part of readline instead of a bash-specific addition.
+k. The signal cleanup code now blocks SIGINT while processing after a SIGINT.
