4103332619 Update to 4.3:
This is a terse description of the new features added to bash-4.3 since
the release of bash-4.2.  As always, the manual page (doc/bash.1) is
the place to look for complete descriptions.

1.  New Features in Bash

a.  The `helptopic' completion action now maps to all the help topics, not just
    the shell builtins.

b.  The `help' builtin no longer does prefix substring matching first, so
    `help read' does not match `readonly', but will do it if exact string
    matching fails.

c.  The shell can be compiled to not display a message about processes that
    terminate due to SIGTERM.

d.  Non-interactive shells now react to the setting of checkwinsize and set
    LINES and COLUMNS after a foreground job exits.

e.  There is a new shell option, `globasciiranges', which, when set to on,
    forces globbing range comparisons to use character ordering as if they
    were run in the C locale.

f.  There is a new shell option, `direxpand', which makes filename completion
    expand variables in directory names in the way bash-4.1 did.

g.  In Posix mode, the `command' builtin does not change whether or not a
    builtin it shadows is treated as an assignment builtin.

h.  The `return' and `exit' builtins accept negative exit status arguments.

i.  The word completion code checks whether or not a filename containing a
    shell variable expands to a directory name and appends `/' to the word
    as appropriate.  The same code expands shell variables in command names
    when performing command completion.

j.  In Posix mode, it is now an error to attempt to define a shell function
    with the same name as a Posix special builtin.

k.  When compiled for strict Posix conformance, history expansion is disabled
    by default.

l.  The history expansion character (!) does not cause history expansion when
    followed by the closing quote in a double-quoted string.

m.  `complete' and its siblings compgen/compopt now takes a new `-o noquote'
    option to inhibit quoting of the completions.

n.  Setting HISTSIZE to a value less than zero causes the history list to be
    unlimited (setting it 0 zero disables the history list).

o.  Setting HISTFILESIZE to a value less than zero causes the history file size
    to be unlimited (setting it to 0 causes the history file to be truncated
    to zero size).

p.  The `read' builtin now skips NUL bytes in the input.

q.  There is a new `bind -X' option to print all key sequences bound to Unix
    commands.

r.  When in Posix mode, `read' is interruptible by a trapped signal.  After
    running the trap handler, read returns 128+signal and throws away any
    partially-read input.

s.  The command completion code skips whitespace and assignment statements
    before looking for the command name word to be completed.

t.  The build process has a new mechanism for constructing separate help files
    that better reflects the current set of compilation options.

u.  The -nt and -ot options to test now work with files with nanosecond
    timestamp resolution.

v.  The shell saves the command history in any shell for which history is
    enabled and HISTFILE is set, not just interactive shells.

w.  The shell has `nameref' variables and new -n(/+n) options to declare and
    unset to use them, and a `test -R' option to test for them.

x.  The shell now allows assigning, referencing, and unsetting elements of
    indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
    count back from the last element of the array.

y.  The {x}<word redirection feature now allows words like {array[ind]} and
    can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).

z.  There is a new CHILD_MAX special shell variable; its value controls the
    number of exited child statues the shell remembers.

aa. There is a new configuration option (--enable-direxpand-default) that
    causes the `direxpand' shell option to be enabled by default.

bb. Bash does not do anything special to ensure that the file descriptor
    assigned to X in {x}<foo remains open after the block containing it
    completes.

cc. The `wait' builtin has a new `-n' option to wait for the next child to
    change status.

dd. The `printf' %(...)T format specifier now uses the current time if no
    argument is supplied.

ee. There is a new variable, BASH_COMPAT, that controls the current shell
    compatibility level.

ff. The `popd' builtin now treats additional arguments as errors.

gg. The brace expansion code now treats a failed sequence expansion as a
    simple string and will continue to expand brace terms in the remainder
    of the word.

hh. Shells started to run process substitutions now run any trap set on EXIT.

ii. The fc builtin now interprets -0 as the current command line.

jj. Completing directory names containing shell variables now adds a trailing
    slash if the expanded result is a directory.

kk. `cd' has a new `-@' option to browse a file's extended attributes on
    systems that support O_XATTR.

ll. The test/[/[[ `-v variable' binary operator now understands array
    references.

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_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.

m.  If the user-settable variable `history-size' is set to a value less than
    0, the history list size is unlimited.

n.  New application-settable variable: rl_signal_event_hook; function that is
    called when readline is reading terminal input and read(2) is interrupted
    by a signal.  Currently not called for SIGHUP or SIGTERM.

o.  rl_change_environment: new application-settable variable that controls
    whether or not Readline modifies the environment (currently readline
    modifies only LINES and COLUMNS).

8095f4d9e4 Update to 4.2.
1.  New Features in Bash

a.  `exec -a foo' now sets $0 to `foo' in an executable shell script without a
    leading #!.

b.  Subshells begun to execute command substitutions or run shell functions or
    builtins in subshells do not reset trap strings until a new trap is
    specified.  This allows $(trap) to display the caller's traps and the
    trap strings to persist until a new trap is set.

c.  `trap -p' will now show signals ignored at shell startup, though their
    disposition still cannot be modified.

d.  $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.

e.  declare/typeset has a new `-g' option, which creates variables in the
    global scope even when run in a shell function.

f.  test/[/[[ have a new -v variable unary operator, which returns success if
    `variable' has been set.

g.  Posix parsing changes to allow `! time command' and multiple consecutive
    instances of `!' (which toggle) and `time' (which have no cumulative
    effect).

h.  Posix change to allow `time' as a command by itself to print the elapsed
    user, system, and real times for the shell and its children.

j.  $((...)) is always parsed as an arithmetic expansion first, instead of as
    a potential nested command substitution, as Posix requires.

k.  A new FUNCNEST variable to allow the user to control the maximum shell
    function nesting (recursive execution) level.

l.  The mapfile builtin now supplies a third argument to the callback command:
    the line about to be assigned to the supplied array index.

m.  The printf builtin has a new %(fmt)T specifier, which allows time values
    to use strftime-like formatting.

n.  There is a new `compat41' shell option.

o.  The cd builtin has a new Posix-mandated `-e' option.

p.  Negative subscripts to indexed arrays, previously errors, now are treated
    as offsets from the maximum assigned index + 1.

q.  Negative length specifications in the ${var:offset:length} expansion,
    previously errors, are now treated as offsets from the end of the variable.

r.  Parsing change to allow `time -p --'.

s.  Posix-mode parsing change to not recognize `time' as a keyword if the
    following token begins with a `-'.  This means no more Posix-mode
    `time -p'.  Posix interpretation 267.

t.  There is a new `lastpipe' shell option that runs the last command of a
    pipeline in the current shell context.  The lastpipe option has no
    effect if job control is enabled.

u.  History expansion no longer expands the `$!' variable expansion.

v.  Posix mode shells no longer exit if a variable assignment error occurs
    with an assignment preceding a command that is not a special builtin.

w.  Non-interactive mode shells exit if -u is enabled and an attempt is made
    to use an unset variable with the % or # expansions, the `//', `^', or
    `,' expansions, or the parameter length expansion.

x.  Posix-mode shells use the argument passed to `.' as-is if a $PATH search
    fails, effectively searching the current directory.  Posix-2008 change.

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.

    encountered an error while converting an integer argument.

b.  Fixed a bug that caused setting one of the compatNN options to not
    turn off the others.

c.  The (undocumented) --wordexp option is no longer included by default.

d.  Fixed a bug in conditional command execution that caused it to not
    correctly ignore the exit status under certain circumstances.

e.  Added a configure-time check for correctly-working asprintf/snprintf.

f.  Fixed some problems with line number calculation and display when sourcing
    a file in an interactive shell.

h.  Fixed a bug that caused an off-by-one error when calculating the directories
    to display with the PROMPT_DIRTRIM option.

2.  Changes to Readline

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

------------------------------------------------------------------------------
This document details the changes between this version, bash-4.1-beta,
and the previous version, bash-4.1-alpha.

1.  Changes to Bash

a.  Fixed a bug in mapfile that caused the shell to crash if it was passed the
    name of an associative array.

b.  Fixed a bug that caused the shell to incorrectly split case patterns if
    they contained characters in $IFS.

c.  Fixed a bug that caused the shell to set $? to the wrong value when using
    a construct ending with a variable assignment with set -x enabled and PS4
    containing a command substitution.

d.  Fixed a bug that caused the shell to read commands incorrectly if an
    expansion error occurred under certain conditions in a user-specified
    subshell.

e.  Fixed a bug that caused the shell to set $? incorrectly if a parse error
    occurred in an evaluation context ("eval", trap command, dot script, etc.)

f.  Fixed a bug that caused the shell to attempt command substitution
    completion within a single-quoted string.

g.  Fixed a bug that caused the shell to insert an extra single quote during
    word completion.

h.  Fixed a bug that caused the shell to crash if invoked with the environment
    variable EMACS having a null value.

i.  Fixed a bug that caused bash to incorrectly report the presence of new
    mail in a `maildir' environment.

j.  Fixed a bug that caused the shell to not recognize a here-document ending
    delimiter inside a command substitution.

k.  Fixed a bug that caused the shell to crash when a a dynamic array variable
    was assigned a scalar value.

2.  Changes to Readline

3.  New Features in Bash

a.  The mapfile/readarray builtin no longer stores the commands it invokes via
    callbacks in the history list.

b.  There is a new `compat40' shopt option.

c.  The < and > operators to [[ do string comparisons using the current locale
    only if the compatibility level is greater than 40 (set to 41 by default).

4.  New Features in Readline

------------------------------------------------------------------------------
This document details the changes between this version, bash-4.1-alpha,
and the previous version, bash-4.0-release.

1.  Changes to Bash

a.  Fixed bugs in the parser involving new parsing of the commands contained
    in command substitution when the substitution is read.

b.  Fixed a bug that caused the shell to dump core when performing programmable
    completion using a shell function.

c.  Fixed a bug in `mapfile' that caused it to invoke callbacks at the wrong
    time.

d.  Fixed a bug that caused the shell to dump core when listing jobs in the
    `exit' builtin.

e.  Fixed several bugs encountered when reading subscripts in associative
    array assignments and expansions.

f.  Fixed a bug that under some circumstances caused an associative array to
    be converted to an indexed array.

g.  Fixed a bug that caused syntax errors and SIGINT interrupts to not set
    $? to a value > 128.

h.  Fixed a bug that caused the shell to remove FIFOs associated with process
    substitution inside shell functions.

i.  Fixed a bug that caused terminal attributes to not be reset when the
    `read' builtin timed out.

j.  Fixed a bug in brace expansion that caused unwanted zero padding of the
    expanded terms.

k.  Fixed a bug that prevented the |& construct from working as intended when
    used with a simple command with additional redirections.

l.  Fixed a bug with the case statment ;& terminator that caused the shell to
    dereference a NULL pointer.

m.  Fixed a bug that caused assignment statements or redirections preceding
    a simple command name to inhibit alias expansion.

n.  Fixed the behavior of `set -u' to conform to the latest Posix interpretation:
    every expansion of an unset variable except $@ and $* will cause the
    shell to exit.

o.  Fixed a bug that caused double-quoted expansions of $* inside word
    expansions like ${x#$*} to not expand properly when $IFS is empty.

p.  Fixed a bug that caused traps to set $LINENO to the wrong value when they
    execute.

q.  Fixed a bug that caused off-by-one errors when computing history lines in
    the `fc' builtin.

r.  Fixed a bug that caused some terminating signals to not exit the shell
    quickly enough, forcing the kernel to send the signal (e.g., SIGSEGV)
    multiple times.

s.  Fixed a bug that caused the shell to attempt to add empty lines to the
    history list when reading here documents.

t.  Made some internal changes that dramatically speeds up sequential indexed
    array access.

u.  Fixed a bug that caused the shell to write past the end of a string when
    completing a double-quoted string ending in a backslash.

v.  Fixed a bug that caused the shell to replace too many characters when a
    pattern match was null in a ${foo//bar} expansion.

w.  Fixed bugs in the expansion of ** that caused duplicate directory names
    and the contents of the current directory to be omitted.

x.  Fixed a bug that caused $? to not be set correctly when referencing an
    unset variable with set -u and set -e enabled.

y.  Fixed a bug caused by executing an external program from the DEBUG trap
    while a pipeline was running.  The effect was to disturb the pipeline
    state, occasionally causing it to hang.

z.  Fixed a bug that caused the ** glob expansion to dump core if it
    encountered an unsearchable directory.

aa. Fixed a bug that caused `command -v' and `command -V' to not honor the
    path set by the -p option.

bb. Fixed a bug that caused brace expansion to take place too soon in some
    compound array assignments.

cc. Fixed a bug that caused programmable completion functions' changes to
    READLINE_POINT to not be reflected back to readline.

dd. Fixed a bug that caused the shell to dump core if a trap was executed
    during a shell assignment statement.

ee. Fixed an off-by-one error when computing the number of positional
    parameters for the ${@:0:n} expansion.

ff. Fixed a problem with setting COMP_CWORD for programmable completion
    functions that could leave it set to -1.

gg. Fixed a bug that caused the ERR trap to be triggered in some cases where
    `set -e' would not have caused the shell to exit.

hh. Fixed a bug that caused changes made by `compopt' to not persist past the
    completion function in which compopt was executed.

ii. Fixed a bug that caused the list of hostname completions to not be cleared
    when HOSTNAME was unset.

jj. Fixed a bug that caused variable expansion in here documents to look in
    any temporary environment.

kk. Bash and readline can now convert file names between precomposed and
    decomposed Unicode on Mac OS X ("keyboard" and file system forms,
    respectively).  This affects filename completion (using new
    rl_filename_rewrite_hook), globbing, and readline redisplay.

ll. The ERR and EXIT traps now see a non-zero value for $? when a parser
    error after set -e has been enabled causes the shell to exit.

mm. Fixed a bug that in brace expansion that caused zero-prefixed terms to
    not contain the correct number of digits.

nn. Fixed a bug that caused the shell to free non-allocated memory when
    unsetting an associative array which had had a value implicitly assigned
    to index "0".

oo. Fixed a memory leak in the ${!prefix@} expansion.

pp. Fixed a bug that caused printf to not correctly report all write errors.

qq. Fixed a bug that caused single and double quotes to act as delimiters
    when splitting a command line into words for programmable completion.

rr. Fixed a bug that caused ** globbing that caused **/path/* to match every
    directory, not just those matching `path'.

ss. Fixed a bug that caused the shell to dump core when running `help' without
    arguments if the terminal width was fewer than 7 characters.

2.  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.

3.  New Features in Bash

a.  Here-documents within $(...) command substitutions may once more be
    delimited by the closing right paren, instead of requiring a newline.

b.  Bash's file status checks (executable, readable, etc.) now take file
    system ACLs into account on file systems that support them.

c.  Bash now passes environment variables with names that are not valid
    shell variable names through into the environment passed to child
    processes.

d.  The `execute-unix-command' readline function now attempts to clear and
    reuse the current line rather than move to a new one after the command
    executes.

e.  `printf -v' can now assign values to array indices.

f.  New `complete -E' and `compopt -E' options that work on the "empty"
    completion: completion attempted on an empty command line.

g.  New complete/compgen/compopt -D option to define a `default' completion:
    a completion to be invoked on command for which no completion has been
    defined.  If this function returns 124, programmable completion is
    attempted again, allowing a user to dynamically build a set of completions
    as completion is attempted by having the default completion function
    install individual completion functions each time it is invoked.

h.  When displaying associative arrays, subscripts are now quoted.

i.  Changes to dabbrev-expand to make it more `emacs-like': no space appended
    after matches, completions are not sorted, and most recent history entries
    are presented first.

j.  The [[ and (( commands are now subject to the setting of `set -e' and the
    ERR trap.

k.  The source/. builtin now removes NUL bytes from the file before attempting
    to parse commands.

l.  There is a new configuration option (in config-top.h) that forces bash to
    forward all history entries to syslog.

m.  A new variable $BASHOPTS to export shell options settable using `shopt' to
    child processes.

n.  There is a new confgure option that forces the extglob option to be
    enabled by default.

o.  New variable $BASH_XTRACEFD; when set to an integer bash will write xtrace
    output to that file descriptor.

p.  If the optional left-hand-side of a redirection is of the form {var}, the
    shell assigns the file descriptor used to $var or uses $var as the file
    descriptor to move or close, depending on the redirection operator.

q.  The < and > operators to the [[ conditional command now do string
    comparison according to the current locale.

r.  Programmable completion now uses the completion for `b' instead of `a'
    when completion is attempted on a line like: a $(b c.

s.  Force extglob on temporarily when parsing the pattern argument to
    the == and != operators to the [[ command, for compatibility.

t.  Changed the behavior of interrupting the wait builtin when a SIGCHLD is
    received and a trap on SIGCHLD is set to be Posix-mode only.

u.  The read builtin has a new `-N nchars' option, which reads exactly NCHARS
    characters, ignoring delimiters like newline.

4.  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.

f551c420e3 Update to 4.0.24. Following bugs were fixed since 4.0.10:
When using the ** globbing operator, bash will incorrectly add an extra
directory name when the preceding directory name ends with `*' or an empty
string when there is no preceding directory name.

If the prompt length exactly matches the screen width, and the prompt ends
with invisible characters, readline positions the cursor incorrectly.

When parsing case statements in command substitutions, the shell did not
note that a newline is a shell metacharacter and can legally be followed
by a reserved word (e.g., `esac').

When not in a locale supporting multibyte characters, readline will
occasionally not erase characters between the cursor position and the end
of the line when killing text backwards.

If a SIGWINCH arrives while bash is performing redisplay, multi-line prompts
are displayed incorrectly due to the display code being called recursively.

Using an external command as part of the DEBUG trap when job control is
enabled causes pipelines to misbehave.  The problem has to do with process
groups assigned to the pipeline and terminal.

A missing include file results in an empty function definition and a no-op
when checking whether or not the window size has changed.

Adding a null line to a here-document (e.g., by hitting EOF) causes the
shell to dump core attempting to dereference the NULL pointer.

There are several problems with the handling of $LINENO in an ERR trap.

Deferring handling of signals which should cause the shell to terminate until
it is "safe" to run the handler functions does not work for some terminating
signals.

When the fc builtin is run in a command substitution from a shell with history
enabled, it does not correctly calculate the command on which to operate.

Though references to $@ when there are no positional parameters will now
cause the shell to exit if the `errexit' option has been enabled, constructs
such as ${@:-foo} should not cause an exit.

A case statement using the ;& pattern terminator followed immediately by
"esac" caused a core dump due to a null pointer dereference.

When using the new |& operator following a simple command with a redirection,
the redirection of stderr through the pipe was not performed under certain
circumstances.

5ff4da9f3a Update to 4.0:
1.  New Features in Bash

a.  When using substring expansion on the positional parameters, a starting
    index of 0 now causes $0 to be prefixed to the list.

b.  The `help' builtin now prints its columns with entries sorted vertically
    rather than horizontally.

c.  There is a new variable, $BASHPID, which always returns the process id of
    the current shell.

d.  There is a new `autocd' option that, when enabled, causes bash to attempt
    to `cd' to a directory name that is supplied as the first word of a
    simple command.

e.  There is a new `checkjobs' option that causes the shell to check for and
    report any running or stopped jobs at exit.

f.  The programmable completion code exports a new COMP_TYPE variable, set to
    a character describing the type of completion being attempted.

g.  The programmable completion code exports a new COMP_KEY variable, set to
    the character that caused the completion to be invoked (e.g., TAB).

h.  If creation of a child process fails due to insufficient resources, bash
    will try again several times before reporting failure.

i.  The programmable completion code now uses the same set of characters as
    readline when breaking the command line into a list of words.

j.  The block multiplier for the ulimit -c and -f options is now 512 when in
    Posix mode, as Posix specifies.

k.  Changed the behavior of the read builtin to save any partial input received
    in the specified variable when the read builtin times out.  This also
    results in variables specified as arguments to read to be set to the empty
    string when there is no input available.  When the read builtin times out,
    it returns an exit status greater than 128.

l.  The shell now has the notion of a `compatibility level', controlled by
    new variables settable by `shopt'.  Setting this variable currently
    restores the bash-3.1 behavior when processing quoted strings on the rhs
    of the `=~' operator to the `[[' command.

m.  The `ulimit' builtin now has new -b (socket buffer size) and -T (number
    of threads) options.

n.  The -p option to `declare' now displays all variable values and attributes
    (or function values and attributes if used with -f).

o.  There is a new `compopt' builtin that allows completion functions to modify
    completion options for existing completions or the completion currently
    being executed.

p.  The `read' builtin has a new -i option which inserts text into the reply
    buffer when using readline.

q.  A new `-E' option to the complete builtin allows control of the default
    behavior for completion on an empty line.

r.  There is now limited support for completing command name words containing
    globbing characters.

s.  Changed format of internal help documentation for all builtins to roughly
    follow man page format.

t.  The `help' builtin now has a new -d option, to display a short description,
    and a -m option, to print help information in a man page-like format.

u.  There is a new `mapfile' builtin to populate an array with lines from a
    given file.  The name `readarray' is a synonym.

v.  If a command is not found, the shell attempts to execute a shell function
    named `command_not_found_handle', supplying the command words as the
    function arguments.

w.  There is a new shell option: `globstar'.  When enabled, the globbing code
    treats `**' specially -- it matches all directories (and files within
    them, when appropriate) recursively.

x.  There is a new shell option: `dirspell'.  When enabled, the filename
    completion code performs spelling correction on directory names during
    completion.

y.  The `-t' option to the `read' builtin now supports fractional timeout
    values.

z.  Brace expansion now allows zero-padding of expanded numeric values and
    will add the proper number of zeroes to make sure all values contain the
    same number of digits.

aa. There is a new bash-specific bindable readline function: `dabbrev-expand'.
    It uses menu completion on a set of words taken from the history list.

bb. The command assigned to a key sequence with `bind -x' now sets two new
    variables in the environment of the executed command:  READLINE_LINE_BUFFER
    and READLINE_POINT.  The command can change the current readline line
    and cursor position by modifying READLINE_LINE_BUFFER and READLINE_POINT,
    respectively.

cc. There is a new &>> redirection operator, which appends the standard output
    and standard error to the named file.

dd. The parser now understands `|&' as a synonym for `2>&1 |', which redirects
    the standard error for a command through a pipe.

ee. The new `;&' case statement action list terminator causes execution to
    continue with the action associated with the next pattern in the
    statement rather than terminating the command.

ff. The new `;;&' case statement action list terminator causes the shell to
    test the next set of patterns after completing execution of the current
    action, rather than terminating the command.

gg. The shell understands a new variable: PROMPT_DIRTRIM.  When set to an
    integer value greater than zero, prompt expansion of \w and \W  will
    retain only that number of trailing pathname components and replace
    the intervening characters with `...'.

hh. There are new case-modifying word expansions: uppercase (^[^]) and
    lowercase (,[,]).  They can work on either the first character or
    array element, or globally.  They accept an optional shell pattern
    that determines which characters to modify.  There is an optionally-
    configured feature to include capitalization operators.

ii. The shell provides associative array variables, with the appropriate
    support to create, delete, assign values to, and expand them.

jj. The `declare' builtin now has new -l (convert value to lowercase upon
    assignment) and -u (convert value to uppercase upon assignment) options.
    There is an optionally-configurable -c option to capitalize a value at
    assignment.

kk. There is a new `coproc' reserved word that specifies a coprocess: an
    asynchronous command run with two pipes connected to the creating shell.
    Coprocs can be named.  The input and output file descriptors and the
    PID of the coprocess are available to the calling shell in variables
    with coproc-specific names.

ll. A value of 0 for the -t option to `read' now returns success if there is
    input available to be read from the specified file descriptor.

mm. CDPATH and GLOBIGNORE are ignored when the shell is running in privileged
    mode.

nn. New bindable readline functions shell-forward-word and shell-backward-word,
    which move forward and backward words delimited by shell metacharacters
    and honor shell quoting.

oo.  New bindable readline functions shell-backward-kill-word and shell-kill-word
    which kill words backward and forward, but use the same word boundaries
    as shell-forward-word and shell-backward-word.

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.

j.  If the kernel supports it, readline displays special characters
    corresponding to a keyboard-generated signal when the signal is received.

d59e5c8ced Update to 3.2:
This document details the changes between this version, bash-3.2-release,
and the previous version, bash-3.2-beta.

1.  Changes to Bash

a.  Fixed a bug that caused the temporary environment passed to a command to
    affect the shell's environment under certain circumstances.

b.  Fixed a bug in the printf builtin that caused the %q format specifier to
    ignore empty string arguments.

c.  Improved multibyte character environment detection at configuration time.

d.  Fixed a bug in the read builtin that left spurious escape characters in the
    input after processing backslashes when assigning to an array variable.

2.  Changes to Readline

a.  Fixed a redisplay bug that occurred in multibyte-capable locales when the
    prompt was one character longer than the screen width.
------------------------------------------------------------------------------
This document details the changes between this version, bash-3.2-beta,
and the previous version, bash-3.2-alpha.

1.  Changes to Bash

a.  Changed the lexical analyzer to treat locale-specific blank characters as
    white space.

b.  Fixed a bug in command printing to avoid confusion between redirections and
    process substitution.

c.  Fixed problems with cross-compiling originating from inherited environment
    variables.

d.  Added write error reporting to printf builtin.

e.  Fixed a bug in the variable expansion code that could cause a core dump in
    a multi-byte locale.

f.  Fixed a bug that caused substring expansion of a null string to return
    incorrect results.

g.  BASH_COMMAND now retains its previous value while executing commands as the
    result of a trap, as the documentation states.

2.  Changes to Readline

a.  Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
    the prompt and input line multiple times.

b.  Fixed history expansion to not be confused by here-string redirection.

c.  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().

------------------------------------------------------------------------------
This document details the changes between this version, bash-3.2-alpha,
and the previous version, bash-3.1-release.

1.  Changes to Bash

a.  Fixed a source bug that caused the minimal configuration to not compile.

b.  Fixed memory leaks in error handling for the `read' builtin.

c.  Changed the [[ and (( compound commands to set PIPESTATUS with their exit
    status.

d.  Fixed some parsing problems with compound array assignments.

e.  Added additional configuration changes for: NetBSD (incomplete multibyte
    character support)

f.  Fixed two bugs with local array variable creation when shadowing a variable
    of the same name from a previous context.

g.  Fixed the `read' builtin to restore the correct set of completion functions
    if a timeout occurs.

h.  Added code to defer the initialization of HISTSIZE (and its stifling of the
    history list) until the history file is loaded, allowing a startup file to
    override the default value.

i.  Tightened up the arithmetic expression parsing to produce better error
    messages when presented with invalid operators.

j.  Fixed the cross-compilation support to build the signal list at shell
    invocation rather than compile time if cross-compiling.

k.  Fixed multibyte support for non-gcc compilers (or compilers that do not
    allow automatic array variable sizing based on a non-constant value).

l.  Several fixes to the code that manages the list of terminated jobs and
    their exit statuses, and the list of active and recently-terminated jobs
    to avoid pid aliasing/wraparound and allocation errors.

m.  Fixed a problem that allowed scripts to die due to SIGINT while waiting
    for children, even when started in the background or otherwise ignoring
    SIGINT.

n.  Fixed a bug that caused shells invoked as -/bin/bash from not being
    recognized as login shells.

o.  Fixed a problem that caused shells in the background to give the terminal
    to a process group other than the foreground shell process group.

p.  Fixed a problem with extracting the `varname' in ${#varname}.

q.  Fixed the code that handles SIGQUIT to not exit immediately -- thereby
    calling functions that may not be called in a signal handler context --
    but set a flag and exit afterward (like SIGINT).

r.  Changed the brace expansion code to skip over braces that don't begin a
    valid matched brace expansion construct.

s.  Fixed `typeset' and `declare' to not require that their shell function
    operands to be valid shell identifiers.

t.  Changed `test' to use access(2) with a temporary uid/euid swap when testing
    file attributes and running setuid, and access(2) in most other cases.

u.  Changed completion code to not attempt command name completion on a line
    consisting solely of whitespace when no_empty_command_completion is set.

v.  The `hash' builtin now prints nothing in posix mode when the hash table is
    empty, and prints a message to that effect to stdout instead of stderr
    when not in posix mode.

w.  Fixed a bug in the extended pattern matching code that caused it to fail to
    match periods with certain patterns.

x.  Fixed a bug that caused the shell to dump core when performing filename
    generation in directories with thousands of files.

y.  Returned to the original Bourne shell rules for parsing ``:  no recursive
    parsing of embedded quoted strings or ${...} constructs.

z.  The inheritence of the DEBUG, RETURN, and ERR traps is now dependent only
    on the settings of the `functrace' and `errtrace' shell options, rather
    than whether or not the shell is in debugging mode.

aa. Fixed a problem with $HOME being converted to ~ in the expansion of
    members of the DIRSTACK array.

bb. Fixed a problem with quoted arguments to arithmetic expansions in certain
    constructs.

cc. The command word completion code now no longer returns matching directories
    while searching $PATH.

dd. Fixed a bug with zero-padding and precision handling in snprintf()
    replacement.

ee. Fixed a bug that caused the command substitution code not to take embedded
    shell comments into account.

ff. Fixed a bug that caused $((...);(...)) to be misinterpreted as an
    arithmetic substitution.

gg. Fixed a bug in the prompt expansion code that inappropriately added a
    \001 before a \002 under certain circumstances.

hh. Fixed a bug that caused `unset LANG' to not properly reset the locale
    (previous versions would set the locale back to what it was when bash
    was started rather than the system's "native" locale).

ii. Fixed a bug that could cause file descriptors > 10 to not be closed even
    when closed explicitly by a script.

jj. Fixed a bug that caused single quotes to be stripped from ANSI-C quoting
    inside double-quoted command substitutions.

kk. Fixed a bug that could cause core dumps when `return' was executed as the
    last element of a pipeline inside a shell function.

ll. Fixed a bug that caused DEBUG trap strings to overwrite commands stored in
    the jobs list.

2.  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.

3.  New Features in Bash

a.  Changed the parameter pattern replacement functions to not anchor the
    pattern at the beginning of the string if doing global replacement - that
    combination doesn't make any sense.

b.  When running in `word expansion only' mode (--wordexp option), inhibit
    process substitution.

c.  Loadable builtins now work on MacOS X 10.[34].

d.  Shells running in posix mode no longer set $HOME, as POSIX requires.

e.  The code that checks for binary files being executed as shell scripts now
    checks only for NUL rather than any non-printing character.

f.  Quoting the string argument to the [[ command's  =~ operator now forces
    string matching, as with the other pattern-matching operators.

4.  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.
