+
+				    1/6
+				    ---
+lib/readline/complete.c
+	- use `convfn' (converted filename) instead of entry->d_name (filename
+	  read from file system) when adding partial or full completions to
+	  the command line.  Bug and fix from Guillaume Outters
+	  <guillaume.outters@free.fr>
+
+				    1/7
+				    ---
+builtins/printf.def
+	- fix prototype in extern declaration for vsnprintf.  Fix for bug
+	  reported by Yann Rouillard <yann@pleiades.fr.eu.org>
+
+				    1/9
+				    ---
+parse.y
+	- fix shell_getc to handle alias expansions containing quoted
+	  newlines.  Problems in bash-4.1 with aliases containing quoted
+	  newlines in the middle of and at the end of their expansion.
+	  Fix for bug reported by Jonathan Claggett
+	  <jonathan@claggett.org>
+	- change mk_alexpansion to not append a space to an alias
+	  expansion ending with a newline.  Works with shell_getc

+				   ----
+doc/{bash.1,{bashref,version}.texi},lib/readine/doc/rluser.texi
+	- some typo fixes from Aharon Robbins <arnold@skeeve.com>
+	- added descriptions of ENV, COPROC, and MAPFILE variables
+	- added descriptions of READLINE_LINE and READLINE_POINT
+
+				   1/21
+				   ----
+arrayfunc.c
+	- free `akey', the word-expanded index into the assoc array to avoid
+	  mem leak in array_value_internal
+	- free index into assoc array in unbind_array_element
+	- change array_value_internal to take an additional argument: an
+	  arrayind_t *.  If not null, an index to an indexed array is
+	  returned there.  If not an indexed array or subscript is @ or
+	  *, the value is unchanged

+
+{configure,config.h}.in
+	- check for <ulimit.h>, define HAVE_ULIMIT_H if found
+
+lib/sh/oslib.c
+	- include <signal.h> for extern declaration for kill(2) if
+	  HAVE_KILLPG not defined
+
+jobs.c
+	- if HAVE_KILLPG is not defined, add an extern prototype decl for
+	  killpg()
+
+				   1/24
+				   ----
+print_cmd.c
+	- when printing here-string redirections, don't quote the string.  The
+	  original quotes, if any, are still in place and don't need to be
+	  requoted.  Fixes bug reported by Arfrever Frehtes Taifersar Arahesis
+	  <arfrever.fta@gmail.com>
+
+subst.c
+	- fix array_length_reference to return 0 for variables that have not
+	  been assigned a value.  Fixes bug reported by Mart Frauenlab
+	  <mart.frauenlob@chello.at>, but is not backwards compatible
+
+arrayfunc.[ch]
+	- change array_value to take a new arrayind_t *indp parameter like
+	  get_array_value; changed extern prototype declaration
+
+subst.c
+	- changed callers of array_value to add extra parameter
+
+expr.c
+	- change expr_streval to set a new `lvalue' parameter with information
+	  about the string being evaluated: string, value, array index (if
+	  any), variable evaluated (if set).
+	- saving and restoring current context now saves and restores the
+	  current `lvalue'
+	- new function expr_bind_array_element, binds an array element with an
+	  already-computed index to a specified value
+	- anywhere we set the current token to a string (STR), save and set
+	  the current lvalue
+	- change calls to expr_bind_variable to check whether or not the
+	  current lvalue indicates an indexed array was evaluated, and, if so,
+	  call expr_bind_array_element using the already-computed index
+	  (curlval.ind).  Fixes problems with dynamic variables (e.g., RANDOM)
+	  in array indices with {pre,post}-{inc,dec}rement and op=
+	  operators reported by <dennis@netstrata.com>
+
+				   1/25
+				   ----
+expr.c
+	- fix subexpr() to initialize curlval and lastlval when resetting all
+	  of the rest of the expression-parsing variables
+
+				   1/26
+				   ----
+builtins/setattr.def
+	- in show_var_attributes, if the variable is not set (value == 0),
+	  don't print `name=""', just print `name'.  Pointed out by
+	  Mart Frauenlab <mart.frauenlob@chello.at>
+
+arrayfunc.c
+	- fix array_keys to return NULL if the variable is not set or
+	  invisible.  Pointed out by Mart Frauenlab <mart.frauenlob@chello.at>
+	- change array_value_internal to return NULL for variable which has
+	  not been set
+
+				   1/30
+				   ----
+bashline.c
+	- in command_word_completion_function, don't call glob_pattern_p
+	  on hint -- use the already-computed `globpat'.  At this point,
+	  hint might contain an already-dequoted globbing character, but
+	  glob_matches will be NULL.  Fixes bug reported by
+	  coyote@wariat.org.pl
+
+				    2/5
+				    ---
+builtins/exec.def
+	- set extern variable "exec_argv0" to the argument to -a
+
+shell.c
+	- if exec_argv0 is set, set dollar_vars[0] to it and set it to NULL,
+	  assuming it was set by `exec -a'.  `exec -a foo' now sets $0 to
+	  foo in an executable shell script without a leading `#!' (fixes
+	  longstanding bug)
+
+				    2/8
+				    ---
+variables.c
+	- in push_func_var, if a variable is in a special builtin's temporary
+	  environment and needs to be propagated because we're in Posix mode,
+	  or we just need to propagate a variable, and we are executing in a
+	  function without any local variables (so the function-local variable
+	  context has no variable hash table), make sure we create a hash
+	  table so we have a place to save the variable to be propagated.
+	  Fixes bug reported by Crestez Dan Leonard <cdleonard@gmail.com>.
+
+				   2/18
+				   ----
+builtins/hash.def
+	- change add_hashed_command to remove the command being looked up from
+	  the hash table before trying to add it.  That way, if it's not found,
+	  there won't be anything remaining in the hash table
+
+				   2/26
+				   ----
+trap.[ch]
+	- move IMPOSSIBLE_TRAP_HANDLER define to trap.h so other parts of the
+	  shell can use it
+
+parse.y
+	- change yy_readline_get to use IMPOSSIBLE_TRAP_HANDER instead of NULL
+	  as a sentinel value for the SIGINT signal handler
+	- make sure yy_readline_get resets interrupt_immediately to 0 after
+	  calling readline() using the same criteria it used to set it to 1
+	  before the call -- make the code symmetric.  Suggested by Werner
+	  Fink <werner@suse.de>
+
+builtins/read.def
+	- move assignment to `retval' before decrement of interrupt_immediately
+	  and terminate_immediately and call to discard_unwind_frame
+	- move assign_vars label before decrement of interrupt_immediately and
+	  terminate_immediately so those variables get reset appropriately
+	  if read -t times out
+
+subst.h
+	- new define for Q_DOLBRACE, indicates double-quoted ${...}
+
+subst.c
+	- in parameter_brace_expand, before calling parameter_brace_expand_rhs,
+	  add Q_DOLBRACE to `quoted' if we're within double quotes.
+	- in expand_word_internal, if the Q_DOLBRACE flag is set, remove a
+	  backslash escaping a }.  Result of a Posix discussion on the
+	  austin-group list
+
+				   2/27
+				   ----
+variables.c
+	- new functions to save and restore the PIPESTATUS variable's internal
+	  array: save_pipestatus_array and restore_pipestatus_array
+
+variables.h
+	- new extern declarations for save_pipestatus_array and
+	  restore_pipestatus_array
+
+trap.c
+	- in run_pending_traps, _run_trap_internal, and run_exit_trap, save
+	  and restore $PIPESTATUS while traps are running.  Fixes bug
+	  reported by Florian Bruhin <me@the-compiler.org>
+
+parse.y
+	- use save_pipestatus_array and restore_pipestatus_array in
+	  save_parser_state and restore_parser_state, respectively, replacing
+	  inline code
+
+lib/readline/histfile.c
+	- fix callers of history_filename to be prepared to cope with it
+	  returning NULL
+	- change history_filename to return NULL if $HOME is not set, rather
+	  than trying to write the history file in the current directory.
+	  This is the default directory, used only if the application does
+	  not specify a history filename.  Changed due to long-ago (unsent)
+	  bug report from OpenBSD
+
+{Makefile,config.h,configure}.in,externs.h,lib/sh/{dprintf.c,Makefile.in}
+	- change fdprintf to dprintf, which is the Posix standard interface,
+	  look for it with configure, replace it if not available
+
+				   2/28
+				   ----
+command.h
+	- add new subshell flag, SUBSHELL_RESETTRAP.  Indicates to the trap
+	  builtin that the shell is executing a command substitution and
+	  should free the trap strings we left unfreed by reset_signal_handlers()
+
+trap.c
+	- free_trap_string() and free_trap_strings() are now compiled in
+
+builtins/trap.def
+	- if changing a signal disposition and the SUBSHELL_RESETTRAP flag is
+	  set in subshell_environment, free the trap strings left unfreed by
+	  reset_signal_handlers
+
+subst.c
+	- in command_substitute, set the SUBSHELL_RESETTRAP flag.  This change
+	  is for Austin Group Posix interpretation 53
+	  (http://austingroupbugs.net/view.php?id=53)
+
+				    3/7
+				    ---
+lib/sh/{Makefile.in,strchrnul.c},Makefile.in
+	- implementation of strchrnul, from gnulib
+
+configure.in,config.h.in
+	- look for strchrnul and compile in version in lib/sh/strchrnul.c if
+	  not available
+	- look for mbsnrtowcs and define HAVE_MBSNRTOWCS if available
+
+lib/sh/xmbsrtowcs.c
+	- new function, xdupmbstowcs2, fast version of xdupmbstowcs used when
+	  mbsnrtowcs is available and the indices are not required.  Called
+	  from xdupmbstowcs as required.  Initial patch from
+	  <0xe2.0x9a.0x9b@gmail.com>
+
+				   3/22
+				   ----
+print_cmd.c
+	- call print_deferred_heredocs virtually every time a recursive call
+	  to make_command_string_internal is made so here documents get
+	  printed correctly when they are attached to commands inside compound
+	  commands such as for and while.  Fixes bug reported by Mike
+	  Frysinger <vapier@gentoo.org>
+
+				   3/25
+				   ----
+builtins/printf.def
+	- fix have_precision case in PF macro to call printf with precision
+	  instead of fieldwidth argument.  Fixes bug reported by Rob Robason
+	  <rob@robason.net>
+
+				   3/26
+				   ----
+trap.[ch]
+	- new function, signal_is_hard_ignored, returns true if the shell
+	  inherited SIG_IGN as a signal's disposition
+	- new function, set_original_signal (sig, handler), provides interface
+	  for rest of shell to set original_signals[sig] = handler
+
+execute_cmd.c
+	- execute_disk_command needs to call reset_terminating_signals in the
+	  child process before resetting traps with restore_original_signals
+
+builtins/trap.def
+	- call initialize_terminating_signals before calling display_traps for
+	  trap -p or trap without any other arguments.  Possible future use
+
+lib/readline/complete.c
+	- rl_filename_completion_function needs to call
+	  rl_filename_dequoting_function with `dirname' (which has already
+	  been tilde-expanded) instead of `users_dirname', because it calls
+	  opendir with `dirname'.  Fixes bug reported by Stefan H. Holek 
+	  <stefan@jarn.com>
+
+				   3/27
+				   ----
+sig.c
+	- experimental change to set_signal_handler: when setting the SIGCHLD
+	  handler, set the SA_RESTART flag so that interruptible system calls
+	  get restarted after a child dies.  Fixes bug reported by Tomas
+	  Trnka <tomastrnka@gmx.com>, but needs further evaluation
+
+lib/sh/eaccess.c
+	- eaccess(2) apparently does only half the job: it does not check that
+	  the permission bits on a file actually allow, for instance, execution.
+	  Need to augment with a call to sh_stataccess if eaccess returns
+	  success on FreeBSD.  Fixes FreeBSD problem reported by Jonan Hattne
+	  <johan.hattne@utsouthwestern.edu>
+
+				   3/28
+				   ----
+parse.y,bashline.c,externs.h
+	- history_delimiting_chars now takes a const char * as an argument:
+	  the line being added to the history.  Changed callers
+
+parse.y
+	- bash_add_history should not add a semicolon separator if the current
+	  history entry already ends in a newline.  It can introduce syntax
+	  errors (e.g., when it results in a null command before a close brace).
+	  Fixes bug reported by Andreas Schwab <schwab@linux-m68k.org>
+
+parse.y
+	- history_delimiting_chars needs to return a newline instead of a
+	  semicolon if it thinks the current line starts a here document
+	  (if it contains `<<').  Also keeps track of the fact with a new
+	  static variable, LAST_WAS_HEREDOC, so it can return the right
+	  sequence of newlines later for the here-document body.  Fixes bug
+	  reported by Andreas Schwab <schwab@linux-m68k.org>
+
+				   3/29
+				   ----
+lib/sh/eaccess.c
+	- if the system has faccessat, sh_eaccess will now use it in
+	  preference to all other options
+
+				   3/30
+				   ----
+subst.h
+	- new string_extract and extract_dollar_brace_string flag value:
+	  SX_POSIXEXP, set if the shell is expanding one of the new Posix
+	  pattern removal word expansions
+
+parser.h
+	- new definitions for "word expansion state", shared between parse.y
+	  and subst.c
+
+subst.c
+	- include parser.h
+
+				    4/9
+				    ---
+builtins/declare.def
+	- make sure declare_internal calls bind_assoc_variable with newly-
+	  allocated memory for the key argument when using an implicit key
+	  of "0".  Bug report and fix from Andreas Schwab
+	  <schwab@linux-m68k.org>
+
+				   4/14
+				   ----
+lib/readline/input.c
+	- restructure the rl_event_hook loop in rl_read_key to call the
+	  event hook after rl_gather_tyi() returns and rl_get_char has
+	  a chance to collect the input.  Previous behavior was to call
+	  the event hook before attempting to read input.  Problem
+	  reported by Anant Shankar <anantshankar17@gmail.com>
+
+				   4/15
+				   ----
+builtins/fc.def
+	- fc_builtin needs to check whether the calculation of last_hist
+	  leaves hlist[last_hist] == 0, and keep decrementing it until it
+	  leaves a non-null history entry or goes < 0.  Currently only
+	  does this if saved_command_line_count > 0, indicating we're
+	  trying to edit a multi-line command.  Fixes bug reported by
+	  Roman Rakus <rrakus@redhat.com>
+
+				   4/17
+				   ----
+subst.c
+	- new process substitution helper functions:
+		unlink_fifo - closes a single FD or FIFO
+		num_fifos - returns number of open FDs or active FIFOs
+		copy_fifo_list - returns a bitmap of open FDs or active FIFOs
+		  by index into appropriate list (dev_fd_list or fifo_list)
+		close_new_fifos - take a bitmap saved by copy_fifo_list and
+		  call unlink_fifo on any FD or FIFO open at the time of the
+		  call that is not marked as active in list
+
+execute_cmd.c
+	- execute_builtin_or_function: use new framework to close process
+	  substitution FDs or FIFOs created by a shell builtin or shell
+	  function.  Fixes bug reported by Charles Duffy <charles@dyfis.net>
+
+doc/{bash.1,bashref.texi}
+	- document 'C and "C constants for printf builtin
+
+				   4/22
+				   ----
+lib/readline/complete.c
+	- new function to return screenwidth for use when displaying possible
+	  matches: complete_get_screenwidth; changed uses of _rl_screenwidth
+	  to use complete_get_screenwidth().
+	- change complete_get_screenwidth to query (readline-private)
+	  _rl_completion_colums, $COLUMNS, then _rl_screenwidth in that order
+	- change rl_display_match_list to deal with limit < 0 (which implies
+	  that cols == 0) when _rl_screenwidth > 0
+
+lib/readline/bind.c
+	- new bindable variable: completion-display-width, controls the
+	  number of columns used when displaying completions with new
+	  sv_compwidth function to call when value is set or unset
+
+lib/readline/doc/{readline.3,rltech.texi}
+	- documented completion-display-width variable
+
+				   4/23
+				   ----
+execute_cmd.c
+	- change execute_in_subshell to reset trap handlers without freeing
+	  the trap strings and set SUBSHELL_RESETTRAP.  In line with Austin
+	  Group interp #53 (trap in a subshell).
+	- ditto for execute_simple_command where it can be determined that
+	  the shell is going to run a builtin or function in a subshell
+
+trap.c
+	- new function, get_all_original_signals, retrieves the original
+	  signal disposition for all signals
+
+trap.h
+	- extern declaration for get_all_original_signals
+
+builtins/trap.def
+	- change showtrap to display signals that are "hard ignored" as
+	  trap commands to ignore them, even though that trap command would
+	  be a no-op.  Partial fix for feature request from Siddhesh
+	  Poyarekar <siddhesh.poyarekar@gmail.com>
+	- change trap_builtin to call get_all_original_signals before displaying
+	  traps.  This will show inherited ignored signals.  Rest of feature
+	  request from Siddhesh Poyarekar <siddhesh.poyarekar@gmail.com>
+
+lib/readline/histexpand.c
+	- fix history_tokenize_word so that it understands $(...) and the
+	   <(...) and >(...) expansions as a single word
+	- change history_tokenize_word so that it understands extended shell
+	  globbing patterns as a single word.  Code is very similar to
+	  $(...) code above.  Bug reported by Rajeev V. Pillai
+	  <rajeevvp@gmail.com>
+
+				   4/24
+				   ----
+lib/readline/vi_mode.c
+	- add checks to rl_vi_char_search to make sure we've already done a
+	  search if the command is `;' or `,', and return immediately if we
+	  have not.  Fixes bug reported by Eric Ho <ericmho@shaw.ca>
+
+lib/readline/text.c
+	- make sure `dir' is in the valid range before searching in
+	  _rl_char_search_internal.  Range checks in the code depend on it
+	  being non-zero
+
+				    5/3
+				    ---
+lib/readline/complete.c
+	- in rl_complete_internal, if show-all-if-ambiguous or
+	  show-all-if-unmodified are set (what_to_do == '!' or '@',
+	  respectively), and the common match prefix is shorter than the
+	  text being completed, inhibit inserting the match.
+	  The guess is that replacing text with a shorter match will not
+	  be wanted
+
+				   5/20
+				   ----
+lib/sh/unicode.c
+	- new file, with unicode character conversion-related code.  Will be
+	  used to implement \u and \U escapes where appropriate, and for
+	  other unicode-related functions in the future
+
+				   5/21
+				   ----
+builtins/printf.def
+	- add code to handle \u and \U escapes in format strings and arguments
+	  processed by the %b format specifier
+
+lib/sh/strtrans.c
+	- add code to handle \u and \U escapes as unicode characters, works for
+	  both `echo -e' and $'...'
+
+doc/{bash.1,bashref.texi}
+	- document new \u and \U escape sequences for $'...' and echo (printf
+	  defers to the system's man page or Posix)
+
+				   5/24
+				   ----
+execute_cmd.c
+	- change execute_disk_command to return a status, instead of just
+	  leaving it in `last_command_exit_value', since the parent's return
+	  value is sometimes used (e.g., when a restricted shell refuses to
+	  run a command with a `/').  Fixes bug reported by David Pitt
+	  <David.Pitt@anz.com>
+
+				   5/25
+				   ----
+bashline.c
+	- change bash completion functions to save and restore the value of
+	  rl_ignore_some_completions_function, and set it to the bash default
+	  of filename_completion_ignore where appropriate.  Fixes bug
+	  reported by Henning Bekel <h.bekel@googlemail.com>
+
+variables.c
+	- new convenience function: find_global_variable (name).  Looks for
+	  NAME in the global variables table, skipping any local and
+	  temporary environment variables
+
+builtins/declare.def
+	- add new -g option to declare/typeset/local, forces variables to be
+	  created or modified at the global scope when executing inside a
+	  shell function.  Requested by many, most recently by
+	  konsolebox@gmail.com
+
+				   5/27
+				   ----
+test.c
+	- added new `-v var' unary test operator; returns TRUE if var is set
+	  (i.e., has been assigned a value).  Works in both test builtin and
+	  [[ conditional command
+
+doc/{bash.1,bashref.texi}
+	- documented new `-v var' unary conditional operator
+
+tests/test.tests
+	- added tests for new -v var operator
+
+builtins/kill.def
+	- change kill builtin so -PID (pgrp specification) following a
+	  -s sig or -n sig option is not interpreted as a signal specification.
+	  Fixes bug reported by Roman Rakus <rrakus@redhat.com>
+
+builtins/evalstring.c
+	- in parse_and_execute, if parse_command() returns non-zero,
+	  indicating a parse error, exit the shell if the conditions require
+	  a posix-mode non-interactive shell to abort (parse error in a `.'
+	  script or eval string).  Bash-4.1 only printed a warning.  This is
+	  from Austin Group interp 114
+
+doc/bashref.texi
+	- add note to the posix mode section of the texinfo manual noting
+	  the changed behavior for `.' and `eval'
+
+parse.y
+	- change time_command_acceptable to allow TIME token to appear after
+	  BANG token (to allow `! time foo', which is supposed to be valid)
+	- change pipeline_command production to allow multiple instances of
+	  `!' (which toggle inverting the return status) and `time' (which
+	  have no effect)
+
+execute_cmd.c
+	- In posix mode, `time' without a following pipeline prints the
+	  elapsed user, system, and real time for the shell and its
+	  children since the shell was invoked.
+	  It's like `times' but obeys the setting of TIMEFORMAT.  A future
+	  revision of Posix will require this
+
+doc/{bashref.texi,bash.1}
+	- document new posix mode use of `time' 
+
+parse.y
+	- add production to pipeline_command that permits `!' by itself to
+	  be equivalent to `false' (and, with the changes above, permits
+	  `! !' to be roughly equivalent to `true').  A future revision of
+	  Posix will require this
+
+				   5/28
+				   ----
+parse.y
+	- fix \W prompt expansion to use memmove instead of strcpy, since the
+	  source and target strings overlap (though you think it wouldn't

+subst.c
+	- change extract_delimited_string to process nested $( as a possible

+	- change parameter_brace_expand_rhs to make the := expansion operator
+	  perform quote removal and both assign the result to the variable and
+	  return it as the result of the expansion, rather than assign the
+	  value after quote removal but return the value before quote removal.
+	  Posix interp 221
+	- introduce new internal quoting flag: Q_DOLBRACE.  Denotes a double-
+	  quoted ${...} expansion.  In this case, Posix interp 221 requires
+	  that a backslash quoting an embedded `}' be removed, even though it's
+	  not one of the characters marked as special inside double quotes.
+	  Set in parameter_brace_expand, used by expand_word_internal.
+
+parse.y
+	- introduce new parsing state, P_DOLBRACE, set when parsing a ${...}
+	  expansion
+	- set a "dolbrace operator state" in parse_matched_pair to decide

+	- if termsig_handler is called when terminate_immediately == 1,
+	  assume we're being called as a signal handler and set
+	  history_lines_this_session to 0 to inhibit history file being
+	  written on shell exit.  Fixes long-standing bug most recently
+	  observed by Andreas Schwab <schwab@linux-m68k.org>
+
+				   11/5
+				   ----
+redir.c
+	- add_undo_close_redirect now returns int, 0 on success, non-zero on
+	  failure.  Currently always succeeds
+	- new macro REDIRECTION_ERROR to make do_redirection_internal return
+	  value of errno
+	- change do_redirection_internal to call REDIRECTION_ERROR after
+	  saving file descriptor and make do_redirection_internal return error
+	  if add_undo_redirect or add_undo_close redirect fails.  This makes
+	  failure to save a file descriptor a redirection error and the shell
+	  behaves appropriately.  Fixes bug reported by Eric Blake
+	  <eblake@redhat.com>
+
+bashline.c
+	- modify bash_forward_shellword to correctly handle quoted strings,
+	  especially if point is in a quoted string when function is invoked.
+	  Fixes bug reported by Daniel Colascione <dan.colascione@gmail.com>
+
+configure.in
+	- change version to 4.2-alpha
+
+				   11/7
+				   ----
+lib/readline/text.c
+	- in rl_insert, if we're not in the multibyte code path, don't try to
+	  optimize and insert all of the available typeahead input if we're
+	  reading input from a macro.  Fixes bug reported by Andre Majorel
+	  <aym-ung@teaser.fr>
+
+lib/readline/text.c
+	- break out multibyte guts of rl_forward_char into a separate function
+	  _rl_forward_char_internal that does nothing but calculate the new
+	  value of point
+	- change rl_forward_char to call _rl_forward_char_internal instead of
+	  having equivalent code inline
+
+lib/readline/rlprivate.h
+	- new extern declaration for _rl_forward_char_internal
+
+lib/readline/vi_mode.c
+	- change _rl_vi_append_forward to call _rl_forward_char_internal to
+	  set rl_point, instead of calling rl_forward_char.  When at the end
+	  of the line, rl_forward_char will ring the bell.  Fixes debian
+	  bash bug 601042, reported by Alan J. Greenberger <alanjg@ptd.net>
+
+				   11/14
+				   -----
+subst.c
+	- fix match_upattern to use correct test to immediately break out of
+	  loop (when potential match length is greater than number of chars
+	  remaining in the string) in MATCH_ANY case
+
+				   11/15
+				   -----
+subst.c
+	- include "typemax.h" to make sure we have a definition of INTMAX_MIN
+
+				   11/16
+				   -----
+lib/sh/unicode.c
+	- make sure `localconv' isn't declared on machines without iconv
+	- add stub_charset for systems that don't have locale_charset: looks
+	  up LC_CTYPE, returns everything after last `.', "UTF-8" if the
+	  value is exactly "UTF-8", and "ASCII" otherwise
+
+				   11/20
+				   -----
+lib/readline/vi_mode.c
+	- in rl_domove_motion_callback, make sure to use m->key instead of
+	  key, which is not initialized and should not be used.  Bug report
+	  from Andreas Schwab <schwab@linux-m68k.org>
+	- in rl_vi_domove, make assignment to `m' explicit instead of
+	  relying on evaluation order semantics, since the C standard leaves
+	  them unspecified.  Bug report from Andreas Schwab
+	  <schwab@linux-m68k.org>
+
+				   11/21
+				   -----
+lib/sh/shquote.c
+	- sh_single_quote and sh_double_quote now take a const char *
+	  argument.  Fixes problem pointed out by Joachim Schmitz
+	  <jojo@schmitz-digital.de>
+
+externs.h
+	- change extern declarations for sh_single_quote and sh_double_quote
+
+lib/sh/strchrnul.c
+	- make sure that return value is cast to (char *) if we're using a
+	  part of the passed (const char *) argument.  Fixes problem pointed
+	  out by Joachim Schmitz <jojo@schmitz-digital.de>
+
+lib/glob/gmisc.c
+	- fix a typo that mixed up defines for LPAREN and RPAREN.  Bug and
+	  fix from Andreas Schwab <schwab@linux-m68k.org>
+	- use WLPAREN and WRPAREN in multibyte character environments
+	- fixed typos using L'cc' in a non-wide-char environment
+
+lib/readline/complete.c
+	- fix rl_filename_completion_function to dequote users_dirname if
+	  there is a filename dequoting function (as well as dirname), since
+	  users_dirname gets tacked back onto the beginning of the possible
+	  completions and then requoted.  Bug reported by Andreas Schwab
+	  <schwab@linux-m68k.org>
+
+				   11/22
+				   -----
+lib/readline/parens.c
+	- the `blink-matching-paren' variable should default to off
+
+				   11/23
+				   -----
+subst.h
+	- add extern declaration for close_new_fifos()
+
+lib/sh/fnxform.c
+	- fix curencoding to return the character past the `.', not a string
+	  beginning with `.'
+
+lib/sh/unicode.c
+	- fix stub_charset to do the same cut-off at `@' as curencoding().
+	  These two functions should be combined
+
+builtins/printf.def
+	- document new %(datefmt)T modifier in help text
+
+				   11/24
+				   -----
+parse.y
+	- fix `W' case in decode_prompt_string: memmove was copying one too
+	  few bytes and missed the closing NUL.  Bug report from Tim Mooney
+	  <Tim.Mooney@ndsu.edu>
+
+				   11/26
+				   -----
+subst.c
+	- in expand_word_internal, don't add quoted nulls to partially-
+	  quoted strings if the word will not be subjected to word splitting
+	  later (which will remove the quoted null).  Fixes bug reported by
+	  Rocky Bernstein <rocky.bernstein@gmail.com>
+
+				   11/28
+				   -----
+subst.c
+	- change multibyte case of match_pattern to revert to match_upattern
+	  if neither the pattern nor the string has any multibyte characters
+
+alias.c
+	- fix tests of backslash-escaped characters in skipquotes, skipws,
+	  rd_token to check for backslash at EOS and not go past the end.
+	  Fixes debian bug 603696 reported by Tim Small <tim@buttersideup.com>
+
+include/shmbchar.h
+	- new file, mbchar.h from gnulib minus the <stdbool.h> include
+
+lib/sh/shmbchar.c
+	- new file, mbchar.c from gnulib with additions
+	- moved mbstrlen from subst.c to here, changed initialization of mbs
+	- change mbstrlen to use is_basic to avoid calls to mbrlen for ASCII
+	  chars; code hints from gnulib
+	- don't copy mbs and mbsbak if we're not calling mbrlen
+
+				   11/29
+				   -----
+lib/glob/smatch.c
+	- change xstrmatch to use internal_strmatch() if the pattern and
+	  string don't have any multibyte characters
+
+				   11/30
+				   -----
+include/shmbutil.h
+	- change ADVANCE_CHAR and ADVANCE_CHAR_P macros to use is_basic and
+	  only call mbrlen and copy state and state_bak if is_basic returns
+	  false (non-ASCII).  Called all over the place.
+	- change rest of macros except BACKUP_CHAR and BACKUP_CHAR_P in the
+	  same way
+
+				   12/2
+				   ----
+subst.c
+	- audit all calls to string_list and make sure caller can handle a
+	  NULL return value.  Fixes bug reported by David Rochberg
+	  <rochberg@google.com>
+
+general.h
+	- change sh_wassign_func_t to take an additional argument: an int
+	  flags word
+
+subst.c
+	- change do_word_assignment to take an additional argument to match
+	  wassign_func_t; change callers
+	- change call to (*assign_func) in expand_word_list_internal to match
+	  new wassign_func_t prototype
+	- (*assign_func) passes 1 as additional arg if the simple command is
+	  a builtin or function, in which case the assignment to the
+	  temporary env should take effect
+
+variables.c
+	- change assign_in_env to take an additional argument to match
+	  wassign_func_t; change callers
+	- move call to sv_ifs from dispose_temporary_env to
+	  dispose_used_env_vars; we don't need to do it if called from
+	  merge_temporary_env
+
+				   12/3
+				   ----
+variables.c
+	- change dispose_temporary_env to maintain a list (tempvar_list) of
+	  variables that need to be handled specially.  If a variable that
+	  gets freed by push_temp_var or propagate_temp_var is one of the
+	  variables that the shell handles specially (IFS, LANG, etc.), it's
+	  stored on the list.  For each variable in this list,
+	  dispose_temp_var calls stupidly_hack_special_variables.
+	- assign_in_env calls stupidly_hack_special_variables if flags arg
+	  is non-zero, so variable assignments affect current shell
+	  execution environment if a builtin or function is being executed.
+	  Fixes bug reported by Bruno Haible <bruno@clisp.org>
+
+				   12/5
+				   ----
+subst.c
+	- use mbsmbchar on both string and pattern in match_pattern instead
+	  of strlen and mbstrlen; only go through the strings once
+
+				   12/6
+				   ----
+lib/readline/kill.c
+	- in rl_yank_last_arg, only switch directions if the `count'
+	  argument is < 0, not < 1.  This makes explicit count arguments of
+	  0 work as expected.  Fixes bug reported by Dennis Williamson
+	  <dennistwilliamson@gmail.com>
+
+doc/bash.1,lib/readline/doc/{readline.3,rluser.texi}
+	- fix documentation for yank-last-arg to make it clear how the count
+	  argument is set and how second and subsequent calls treat any
+	  numeric argument
+
+doc/{bash.1,bashref.texi}
+	- slight changes to the description of test
+	- change \(bv to `|'; it seems that many `internationalized' versions
+	  of groff don't render that as a vertical bar.  Fixes Debian bug
+	  603805
+
+				   12/10
+				   -----
+configure.in
+	- changed release status to 4.2-beta
+
+[bash-4.2-beta frozen]
+
+				   12/18
+				   -----
+redir.c
+	- change REDIRECTION_ERROR macro to accept a third argument: an
+	  additional file descriptor to close before returning and error (pass
+	  -1 to do nothing)
+	- change calls to REDIRECTION_ERROR to close appropriate file
+	  descriptors.  Fixes bug reported by Andreas Schwab
+	  <schwab@linux-m68k.org>
+	- make sure to close any file descriptors opened for REDIR_VARASSIGN
+	  before returning an error
+
+				   12/19
+				   -----
+expr.c
+	- move processing of unary `-' and `+' to exp1 from exp0 to avoid
+	  precedence problems.  Fixes bug reported by <12bric@gmail.com>
+
+				   12/21
+				   -----
+lib/sh/unicode.c
+	- fixed reversed arguments to wctomb.  Reported by Andreas Schwab
+	  <schwab@linux-m68k.org>
