+builtins/common.c
+ - display_signal_list: if 0 is supplied as an argument to kill -l,
+ display a signal-out-of-range error. Fixes bug reported by
+ Martijn Dekker <martijn@inlv.org>
+
+ 9/18
+ ----
+print_cmd.c
+ - print_heredoc_bodies: take a list of redirections, all here documents,
+ and print the here-document bodies including the ending delimiter,
+ followed by a newline
+ - print_redirection_list: print the heredoc headers the first time
+ through the list of redirections so we print them in the same left-
+ to-right order they're supplied; print the bodies and delimiters with
+ print_heredoc_bodies after we print all the redirections if we're
+ not printing a list of commands (printing_connection == 0). Fix for
+ problem reported by Isabella Parakiss <izaberina@gmail.com>
+ - print_deferred_heredocs: don't print heredoc headers, since they're
+ now printed in print_redirection_list
+ - print_deferred_heredocs: use print_heredoc_bodies

+test.c
+ - test_binop: if op[0] == '-', make sure op[1] != 0 before checking
+ op[2] or op[3]. Fixes out-of-bounds read reported by Franco
+ Costantini <franco.costantini.20@gmail.com>
+
+parse.y
+ - cond_term: if yylval.word->word[0] == '-' make sure word[1] != 0
+ before checking word[2] and calling test_unop. Fixes out-of-bounds
+ read reported by Franco Costantini <franco.costantini.20@gmail.com>
+ - make sure to check all instances of the return value of the
+ simple_command production before trying to hook redirections onto it,
+ since it can potentially return NULL.
+ Reported by Franco Costantini <franco.costantini.20@gmail.com>
+

+parse.y
+ - token_is_assignment: make sure to check that the return value from

+ positives from g=g=g=g=g=g=(). Reported by Franco Costantini
+ <franco.costantini.20@gmail.com>
+
+ 9/22
+ ----
+parse.y
+ - token_is_assignment: if we're not using the bash malloc (which has
+ guard bytes after the requested allocation size), use a new
+ buffer so we can make sure it's big enough to hold the current
+ token and at least two additional characters. Reported by
+ Franco Costantini <franco.costantini.20@gmail.com>

+execute_cmd.c
+ - execute_in_subshell: call without_job_control for both job control
+ and non-job-control builds to avoid waiting for last_made_pid
+ inherited from parent shell. Related to fix from 8/4 to
+ initialize_subshell. Fixes bug reported by Martijn Dekker
+ <martijn@inlv.org>
+
+builtins/declare.def
+ - local_builtin: allow `local --help' to work even when not executing
+ a function. Suggestion from Norm Abramovitz <norm@starkandwayne.com>
+
+ 9/25
+ ----
+builtins/printf.def
+ - bexpand: if passed a null or empty string, return a newly-allocated
+ empty string (so the return value can always be freed) instead of
+ NULL.
+ - printstr: if passed a null string, treat it as if it were an empty
+ string so any precision or fieldwidth arguments are handled
+ correctly. Report from isabella parakiss <izaberina@gmail.com>
+
+subst.c
+ - skip_matched_pair: make the flags argument of 1 affect whether or
+ not backslash can quote characters in the string, so it affects
+ all quoting mechanisms
+
+arrayfunc.c
+ - unbind_array_element: now takes a third (flags) argument; flags&1
+ means to not expand an associative array index. This is only called
+ from a shell builtin context, which means the argument should have
+ already undergone word expansion, so it should be ok. Will still
+ be a problem for uses like "unset -v 'var[$ind]'", quoted to avoid
+ globbing
+ - valid_array_reference: pass second flags argument to skipsubscript;
+ still set to 0 by all callers
+
+arrayfunc.h
+ - unbind_array_element: updated prototype
+
+builtins/set.def
+ - unset_builtin: add third argument of 1 to unbind_array_element calls
+ [TEMPORARILY DISABLED]
+ - unset_builtin: call valid_array_reference with second arg of 1 to
+ handle unmatched pairs of quotes and [/]
+
+array.c
+ - array_reference: optimize access locality as well as sequential
+ access by adding ability to start from last-accessed element and move
+ backwards or forwards depending on the desired index. Inspired by
+ report from Tom McCurdy <tom.j.mccurdy@gmail.com> and followup from
+ Christian Franke <Christian.Franke@t-online.de>
+
+variables.c
+ - all_array_variables: include associative arrays, not just indexed
+ arrays. Reported by Grisha Levit <grishalevit@gmail.com>
+
+execute_cmd.c
+ - execute_disk_command: if we're optimizing out the fork (CMD_NO_FORK),
+ decrement the shell level so we don't end up incrementing it twice.
+ We should decrement the shell level for an implicit exec like an
+ explicit one. Reported by Stephane Chazelas
+ <stephane.chazelas@gmail.com>
+
+builtins/exec.def
+ - exec_builtin: don't bother to decrement the shell level if we are
+ already in a `(command)' subshell. Reported by Stephane Chazelas
+ <stephane.chazelas@gmail.com>
+
+lib/readline/macro.c
+ - macro_level: count of macro nesting level, maintained by
+ _rl_push_executing_macro and _rl_pop_executing macro
+ - _rl_with_macro_input: if current nesting level exceeds
+ MAX_MACRO_LEVEL, abort the current command line with _rl_abort_internal
+ and return to the top level. Reported by Christian Klomp
+ <christianklomp@gmail.com>
+
+lib/readine/history.c
+ - add_history: if allocating the history list for the first time,
+ make sure the max history list size isn't so large that it will
+ cause allocation errors. Cap it at MAX_HISTORY_INITIAL_SIZE
+ (8192). Reported by Sean Zha <freeman_cha@hotmail.com>
+
+jobs.c
+ - wait_for: if a foreground job with job control enabled is killed by a
+ SIGINT and sourcelevel != 0, act as if we received the SIGINT so the
+ file sourcing can be terminated. Reported by PePa
+ <peterkelly@passchier.net>
+
+ 9/26
+ ----
+subst.c
+ - read_comsub: only warn once for null bytes in command substitution
+ output, instead of once for every null byte
+
+arrayfunc.c
+ - array_variable_part: now takes a `flags' argument; changed all callers
+ to initially pass 0
+ - array_variable_name: now takes a `flags' argument; changed all callers
+ to initially pass 0
+ - array_variable_name: pass `flags' argument to skipsubscript instead
+ of just passing 0
+
+arrayfunc.h
+ - array_variable_{name,part}: added new argument to prototypes
+
+ 9/29
+ ----
+bashline.c
+ - bash_directory_completion_hook: don't bother to try and expand a
+ ${ or $( that isn't complete; expand_prompt_string will complain.
+ Fixes reports from John Passaro <john.a.passaro@gmail.com> and
+ Valentin Bajrami <valentin.bajrami@gmail.com>
+
+lib/readline/history.c
+ - _hs_append_history_line: use a strategy that attempts to avoid
+ realloc copying memory to a newly-allocated block if the history
+ line we're appending to gets `too long' (currently 256 bytes).
+ We reallocate in powers of 2 starting at 512, and rely on realloc
+ not allocating a new block and copying into it if the size is the
+ same as the last call to realloc. Addresses issue raised by
+ Hubert Schmid <h.schmid@gmx.de>
+
+trap.h
+ - check_signals: new extern declaration
+ - trapped_signal_received: new extern declaration
+
+builtins/read.def
+ - read_builtin: if one of the zread* functions returns < 0 (which
+ usually only happens in Posix mode), make sure we call check_signals()
+ before eventually calling run_pending_traps() because zread() isn't
+ going to call it
+ - include trap.h for correct extern functions and variable declarations
+
+lib/sh/zread.c
+ - zread: if executing a builtin, call check_signals_and_traps() for
+ backwards compatibility. If not, call check_signals() only, because
+ we don't want to run traps during, for instance, reading command
+ substitution output. Fixes race condition bug reported by Luiz Angelo
+ Daros de Luca <luizluca@gmail.com>
+
+ 9/30
+ ----
+subst.c
+ - command_substitute: reset parse_and_execute_level to 0 in the child
+ process, since it's independent of the other parse_and_execute
+ calls. Adds command substitution inside other parse_and_execute
+ calls optimizations to suppress forks, as suggested by
+ Martijn Dekker <martijn@inlv.org>
+
+ 10/3
+ ----
+configure.ac
+ - SHOBJ_STATUS: make sure it defaults to unsupported and is substituted
+ if the shobj-conf script isn't run. Fixes `make install' bug with
+ a minimal config reported by Andrew Tomazos <andrewtomazos@gmail.com>
+
+ 10/5
+ ----
+support/shobj-conf
+ - darwin: set compatibility_version for a shared build of the readline

+ $(SHLIB_MAJOR)$(SHLIB_MINOR). Recommendation from Max Horn
+ <max@quendi.de>
+
+ 10/6
+ ----
+array.h
+ - array_first_index: new convenience define
+
+array.c
+ - ADD_AFTER: new define, complement of ADD_BEFORE
+ - UNSET_LASTREF: now takes an array as an argument, prepping for move
+ of lastref pointer into the array struct
+ - array_insert: check whether we are adding at the beginning of the
+ array and take a fast path if so
+ - array_insert: use same strategy as array_reference to find the place
+ to insert, starting from the last-referenced element and moving
+ forward or back from there; use ADD_AFTER if moving backward
+ - array_insert: if replacing an existing element, just replace the
+ value with new->value instead of the entire element
+ - array_reference: short-circuit quickly if looking for an element
+ before the first assigned index
+ - array_reference: if we don't find the element, leave lastref pointing
+ to the closest element under the assumption we will be assigning or
+ looking for something close
+ - array_reference: take advantage of ordered indexes to short-circuit
+ when looking for element that is not set
+
+ 10/7
+ ----
+array.c
+ - array_remove: short-circuit if asked to remove index after max
+ index or before first index
+
+ 10/10
+ -----
+lib/malloc/malloc.c
+ - internal_realloc: if we are requesting reallocation to the same size
+ as the block's current size, short-circuit and return `mem' right
+ after doing bounds check
+ - internal_realloc: if we are reducing the size of an allocation, and
+ the new size fits in the next lower bin, just keep the same block
+ and adjust the size, so we can avoid some copies
+
+parse.y
+ - set_line_mbstate: keep track of the allocated size of
+ shell_input_line_property, only request reallocation if the size
+ increases, but don't let it get too big
+
+ 10/11
+ -----
+jobs.c
+ - wait_for_background_pids: make sure we wait for pid in
+ last_procsub_child since it's not found in any job -- still needs
+ more work to wait for multiple process substitutions
+
+subst.c
+ - process_substitute: if make_child fails, make sure we call
+ restore_pipeline to undo the previous save_pipeline()
+
+ 10/15
+ -----
+subst.c
+ - process_substitute,command_substitute: leave subshell_level (reflected
+ as $BASH_SUBSHELL) intact for any exit trap instead of decrementing
+ it. Suggested by Martijn Dekker <martijn@inlv.org>
+
+builtins/evalstring.c
+ - optimize_subshell_command: new function, framework for optimizing
+ out forks for command that have already forked and are executing
+ in a subshell. Not used yet
+
+expr.c
+ - readtok: if we have a post-increment or post-decrement, and the
+ previous token is not a string, check whether the previous token is
+ a number that results from a pre-increment or pre-decrement, and
+ make that an error. Report from Conrad Hoffmann <ch@bitfehler.net>
+
+ 10/16
+ -----
+aclocal.m4
+ - BASH_JOB_CONTROL_MISSING: convert from AC_TRY_RUN to AC_TRY_COMPILE
+ with existing set of preprocessor defines, so it can work when
+ cross-compiling. Suggested by Felix Janda <felix.janda@posteo.de>
+
+ 10/19
+ -----
+variables.c
+ - get_bashpid: BASHPID is no longer readonly; assignments to it are
+ just ignored.
+
+doc/{bash.1,bashref.texi}
+ - BASHPID: note that assignments are ignored and unsetting BASHPID
+ causes it to lose its special properties
+
+ 10/28
+ -----
+builtins/pushd.def
+ - popd_builtin: make sure to check the normalized stack offset
+ (i.e., negatives counting back from the end of the stack) is within
+ bounds before trying to free that stack entry. Report from
+ Fernando Muñoz <fernando@null-life.com>
+
+lib/readline/histfile.c
+ - chown: protect calls with HAVE_CHOWN. Fixes for MinGW{64,32} from
+ J. Peter Mugaas <jpmugaas@suddenlink.net>
+
+lib/readline/colors.c
+ - S_ISDIR: add define if missing

+ - maybe_add_history: set current_command_line_comment for first line
+ of command
+ - bash_add_history: chars_to_add set to "\n" if the current command line
+ is one greater than the previous line containing a comment
+ (current_command_line_comment). Fixes complaint from back in
+ January, 2016 from Dave Rutherford <dave@evilpettingzoo.com>
+
+array.h
+ - lastref: move last-referenced pointer into each array struct, so all
+ arrays can have reference locality
+
+array.c
+ - array_create: set lastref element to 0
+ - array_copy: if copying the lastref in array a, set the new lastref
+ in the copy to the same element
+ - IS_LASTREF, LASTREF_START, LASTREF, INVALIDATE_LASTREF, SET_LASTREF,
+ UNSET_LASTREF: change to use new array `lastref' member
+
+pathexp.c
+ - quote_string_for_globbing: if quoting for a regexp, make sure to
+ skip and copy a leading `^' in a bracket expression, and skip and
+ copy a subsequent `]' (after an optional `^'), so that leading
+ bracket doesn't close the bracket expression. Report from
+ Stephane Chazelas <stephane.chazelas@gmail.com>
+
+ 10/29

+ process substitution
+ - extract_dollar_brace_string: add calls to CHECK_STRING_OVERRUN for

+ - extract_dollar_brace_string: use skipsubscript to skip over the
+ array subscript in ${var[sub]} (non-quoted case uses string_extract,
+ which already uses skipsubscript). Tagged for bash-5.0
+
+ 10/30
+ -----
+variables.c
+ - EPOCHSECONDS: new dynamic variable, time in seconds since Unix

+lib/malloc/malloc.c
+ - posix_memalign: add new posix-mandated interface
+
+examples/loadables/rm.c

+lib/glob/sm_loop.c
+ - parse_collsym: make sure to not return an out-of-bounds read if a

+ - brackmatch: after incrementing p, before checking whether it's a
+ character range, check whether *p was NULL before the increment
+ and short-circuit the bracket expression if it is
+
+jobs.c
+ - discard_last_procsub_child: new function, safely discards
+ last_procsub_child and sets it to NULL
+
+subst.c
+ - process_substitute: call discard_last_procsub_child instead of
+ calling discard_pipeline directly. Fixes bug reported by
+ Christian Weisgerber <naddy@mips.inka.de>
+
+ 11/3
+ ----
+shell.h
+ - EX_DISKFALLBACK: new special return status available to builtins;

+ the builtin
+
+examples/loadables/rm.c
+ - if we see the -i option, return EX_DISKFALLBACK
+
+execute_cmd.c
+ - execute_simple_command: if executing a builtin returns EX_DISKFALLBACK,
+ try running execute_disk_command instead
+
+bashline.c
+ - shell_expand_line: use expand_word to expand the readline line
+ buffer, which allows us to pass flags with the word. If a numeric
+ argument is supplied, do not perform quote removal (pass
+ Q_HERE_DOCUMENT since here-doc quoting does the right thing) and
+ do not perform command or process subsitution. From a suggestion
+ by Dabrien 'Dabe' Murphy <dabe@dabe.com> based on an old bug-bash
+ discussion
+
+subst.c
+ - expand_word_internal: note that we have added a quoted IFS char to
+ istring by setting sentinel has_quoted_ifs. Usually we only add
+ one if we are not going to be performing word splitting, but we
+ will not perform word splitting if there's no expansion, so we need
+ to take care of that case
+ - expand_word_internal: when performing final word split, if there are
+ no expansions but has_quoted_ifs is non-zero, call remove_quoted_ifs()
+ to remove any quoted ifs characters we added while processing
+ - remove_quoted_ifs: new function, removes CTLESC chars preceding
+ (single-byte) chars in IFS. Used when we are not performing word
+ splitting. Fixes bug reported by Martijn Dekker <martijn@inlv.org>

+builtins/evalstring.c
+ - parse_and_execute: make sure the parser is not expanding an alias

+ existing saved history entry alone. Fixes problem with ^N not working
+ at the end of the history if we previously moved back to the start
+ of history
+
+lib/readline/histfile.c
+ - read_history_range: when reading until FROM lines with a history
+ file that has timestamps, make sure to skip to the end of the command
+ line corresponding to the FROMth line instead of leaving line_start
+ pointing to it, and keep track of the start of the last timestamp in
+ last_ts for use by the loop below. Fix for history -n bug reported
+ by HIROSE Masaaki <hirose31@gmail.com>
+
+lib/readline/display.c
+ - init_line_structures: if, for some reason, _rl_screenwidth ends up
+ bigger than the line_size default of 1024 (e.g., gdb's setting the
+ terminal width to 0), make sure line_size is at least _rl_screenwidth.

+ RNG (always available)
+ - SRANDOM: expand to a 32-bit random number. This is not a LCRNG, so
