 	- _rl_dispatch_subseq, _rl_subseq_result: don't call _rl_unget_char
 	  if we're currently reading from a macro; call _rl_prev_macro_key
 	  instead.  Fixes bug reported by Clark Wang <clark.wang@oracle.com>

+builtins/evalstring.c
+	- evalstring(): new function, wrapper around parse_and_execute.
+	  make sure we handle cases where parse_and_execute can call `return'
+	  and short-circuit without cleaning up properly.  We call
+	  parse_and_execute_cleanup() then jump to the previous-saved return
+	  location
+
+builtins/common.h
+	- extern declaration for evalstring()
+
+builtins/eval.def
+	- eval_builtin: make sure we handle `eval " ... return"' in contexts
+	  where `return' is valid by calling evalstring().  Fixes bug with
+	  `eval return' in sourced files reported by Clark Wang
+	  <dearvoid@gmail.com>
+
+trap.c
+	- run_pending_traps: call evalstring instead of parse_and_execute.
+	  XXX - still needs to handle saving and restoring token state in the

+	  it always points to *dirname and only free it if we're replacing
+	  it.
+
+lib/readline/complete.c

+
+builtins/reserved.def
+	- fix description of `CDPATH'
+
+lib/readline/display.c

+
+make_cmd.c

+
+				   7/30
+				   ----
+bashline.c
+	- small changes to glob_expand_word to perform tilde expansion before
+	  attempting globbing
+
+builtins/Makefile.in
+	- fix the install-help target to not cd into the `helpfiles'
+	  subdirectory, so a value of $INSTALL_DATA containing a relative
+	  pathname (e.g., .././support/install.sh) remains valid
+
+				   7/31

+subst.c
+	- new function, mbstrlen(s), returns length of a multibyte character
+	  string
+
+include/shmbutil.h
+	- new macro, MB_STRLEN(s), calls mbstrlen or STRLEN as appropriate
+
+builtins/trap.def
+	- small change so that a first argument that's a valid signal number
+	  (digits only -- no symbolic names) will be treated as a signal and
+	  reverted back to the original handling disposition.  Fixes debian
+	  complaints
+
+subst.c

+	  parameter_brace_expand_length to handle multibyte characters properly
+	- call MB_STRLEN instead of strlen in verify_substring_values so that
+	  negative substrings of strings with multibyte chars work properly
+
+				    8/1
+				    ---
+jobs.c
+	- describe_pid needs to write to stderr, not stdout (POSIX)
+	- start_job, since it's only used by builtins (fg/bg), needs to write
+	  its output to stdout, not stderr (POSIX)
+
+sig.c
+	- add an `orig_flags' member to struct terminating_signal so the
+	  original signal handling flags (SA_RESTART, etc.) can be preserved
+	  on POSIX systems
+	- make sure to preserve the signal flags state in
+	  initialize_terminating_signals and reset them for child processes
+	  in reset_terminating_signals
+
+builtins/fc.def
+	- fixed an off-by-one error that caused `fc -l' to list one too many
+	  history entries
+	- in posix mode, `fc' should not list any indication as to whether or
+	  not history lines have been modified (POSIX)
+	- when in posix mode, the default editor for `fc' should be `ed' (POSIX)
+
+doc/bashref.texi
+	- updated the description of `trap' behavior when given a first
+	  argument that is a valid signal number
+	- noted that `fc -l' won't indicate whether a history entry has been
+	  modified if the shell is in posix mode
+
+builtins/command.def
+	- fixed bug: `command -v' is supposed to be silent if a command is not
+	  found
+
+builtins/hash.def
+	- `hash' should print its `hash table empty' message to stderr
+
+lib/readline/misc.c
+	- back out 7/7 change to _rl_maybe_save_line; it breaks emacs-mode ^P
+
+general.c
+	- changed base_pathname so that it will return reasonable results for
+	  non-absolute pathnames -- this is what is intended by all of its
+	  callers
+
+arrayfunc.c
+	- fix array_variable_part to return NULL if it finds an invisible
+	  variable in the hash table.  Fixes seg fault caused by referring to
+	  unset local variable using array notation
+
+{locale,variables}.c
+	- support LC_TIME as a special locale variable so HISTTIMEFORMAT tracks
+	  the current locale
+
+				    8/2
+				    ---
+variables.c
+	- fixed small memory leak in makunbound() when a local array variable
+	  is unset.  Fix from William Park
+
+lib/readline/display.c
+	- fixed a problem when computing the number of invisible characters on
+	  the first line of a prompt whose length exceeds the screen width
+	  (should only happen when invisible characters occur after the
+	  line wrap).  Bug reported by agriffis@gentoo.org
+
+builtins/command.def
+	- `command -V' passes a new flag, CDESC_ABSPATH, which means to convert
+	  to an absolute path
+
+builtins/type.def
+	- in posix mode, `type' and `command -v/-V' should not report
+	  non-executable files, even if the execution code will attempt to
+	  run them.  Other posix shells do this
+
+doc/bashref.texi
+	- add note to POSIX Mode section describing behavior of type and command
+	  when finding a non-executable file
+
+execute_cmd.c
+	- force extended_glob to 1 before calling binary_test in
+	  execute_cond_node so that the right extended pattern matching gets
+	  performed
+
+				    8/3
+				    ---
+braces.c
+	- make sure lhs[0] and rhs[0] are cast to `unsigned char' so chars
+	  with values > 128 are handled correctly
+
+builtins/printf.def
+	- change bexpand() and printstr() to handle strings with a leading
+	  '\0' whose length is non-zero, since that's valid input for the
+	  `%b' format specifier
+
+subst.c
+	- fix a couple of instances of find_variable that didn't check the
+	  result for an invisible variable
+
+variables.c
+	- BASH_ARGC, BASH_ARGV, BASH_SOURCE, BASH_LINENO no longer created as
+	  invisible vars
+
+pcomplete.c
+	- make sure COMP_WORDS is not invisible when bind_comp_words returns
+	- ditto for COMPREPLY in gen_shell_function_matches
+
+				    8/4
+				    ---
+braces.c
+	- fix problem where ${ was ignored but did not increment the open
+	  brace count.  Bug reported by Tim Waugh <twaugh@redhat.com>
+
+variables.c
+	- if make_local_variable finds a variable in the correct context in
+	  the right variable scope, make sure it's not invisible before
+	  returning it
+
+				    8/5
+				    ---
+builtins/trap.def
+	- fixed usage message to show `action' as not optional, though it
+	  actually is when not in posix mode (for a single argument)
+
+				    8/7
+				    ---
+configure.in
+	- kfreebsd-gnu has had its sbrk() problems fixed, and no longer needs
+	  to be configured --without-gnu-malloc
+
+lib/readline/vi_mode.c
+	- in rl_vi_search, free any saved history line before starting the
+	  search, so failure leaves you at that line, not the last line in
+	  the history (assuming the current line is not the last history line).
+	  Fix from llattanzi@apple.com to replace fix of 7/7
+
+				    8/9
+				    ---
+support/Makefile.in
+	- renamed `mostly-clean' target to `mostlyclean'
+
+				   8/11
+				   ----
+lib/readline/vi_mode.c
+	- make same change for EOL in multibyte character case of
+	  rl_vi_change_char
+
+				   8/12
+				   ----
+subst.c
+	- in verify_substring_values, fix off-by-one error checking bounds of
+	  `offset', esp. in array values (e.g., getting the highest element
+	  of an array)
+
+				   8/16
+				   ----
+aclocal.m4
+	- change BASH_CHECK_DEV_FD to make sure that file descriptors > 2 are
+	  accessible via /dev/fd, unlike FreeBSD 5.x
+
+lib/sh/strftime.c
+	- make sure `zone' is initialized with gettimeofday before it is used
+	- work around HPUX lack of `altzone' and differing definitions of
+	  `timezone'
+
+lib/malloc/malloc.c
+	- internal_memalign and memalign now take a `size_t' as their first
+	  argument, which seems to be the prevailing standard
+
+lib/malloc/{malloc.c,shmalloc.h}
+	- change sh_memalign to take a `size_t' as its first argument
+
+builtins/echo.def
+	- if posixly_correct and xpg_echo are both set, don't try to interpret
+	  any arguments at all, as POSIX/XOPEN requires (fix inspired by Paul
+	  Eggert)
+
+doc/bashref.texi
+	- amend description of bash posix mode to include new echo behavior
+
+builtins/fg_bg.def
+	- allow bg to take multiple job arguments, as posix seems to specify,
+	  placing them all in the background, returning the status of the last
+	  one as the status of `bg'
+
+lib/readline/vi_mode
+	- fix _rl_vi_change_mbchar_case (multibyte-char version of `~'
+	  command) to have the right behavior at EOL -- handle case where vi
+	  mode backs up at the end of the line
+
+				   8/18
+				   ----
+array.c
+	- check for an empty array in array_rshift before shifting elements
+	  and adjusting max_index
+	- check for null array in array_subrange
+
+jobs.c
+	- fix raw_job_exit_status to not ignore exit status of the last
+	  process in the pipeline when `set -o pipefail' is enabled
+
+				   8/19
+				   ----
+lib/readline/mbutil.c
+	- make sure _rl_find_next_mbchar_internal has a valid multibyte
+	  character before it checks whether or not it's a zero-width
+	  wide character and adjusts point accordingly
+
+                                  8/24
+                                   ----
+bashline.c
+        - new function, bash_directory_expansion, duplicates the expansions
+          performed on the directory name by rl_filename_completion_function
+        - call bash_directory_expansion in command_word_completion_function
+          if we decide we're doing tilde expansion (and any other
+          canonicalization) on the directory name being completed
+
+                                   8/25
+                                   ----
+configure.in
+        - use new-style AC_CHECK_HEADER to check for sys/ptem.h (which requires
+          sys/stream.h).  The correct checks are in the code, but autoconf
+          complains if sys/stream.h is not included, rather than simply
+          checking for the header's presence
+
+				   8/26
+				   ----
+builtins/hash.def
+	- fix a bug that prevented `hash -d' from working right (as soon as
+	  hash removed a command from the table, the bug caused it to be added
+	  right back)
+
+				   8/27
+				   ----
+doc/{bash.1,bashref.texi}
+	- explicitly note that conditional primaries that operate on files
+	  operate on the targets of symbolic links rather than the links
+	  themselves
+
+				   8/30
+				   ----
+lib/readline/display.c
+	- fix multibyte calculation of `physchars' in prompt expansion, to
+	  handle double-width multibyte characters correctly
+	- changes to rl_redisplay to handle prompts longer than the screenwidth
+	  that might contain double-width multibyte characters.  Fixes from
+	  Tomohiro Kubota
+
+				    9/6
+				    ---
+subst.c
+	- change word_list_split to avoid really bad behavior caused by calling
+	  list_append for each split word -- as the list gets long, you have
+	  to traverse it every time.  Keep a pointer to the end of the list and
+	  and just tack onto it
+
+				    9/8
+				    ---
+lib/readline/complete.c
+	- change fnprint to calculate the displayed width of a filename in
+	  the same way as fnwidth
+
+subst.c
+	- in verify_substring_values, when expanding ${array[@]:offset}, make
+	  sure negative offsets count from one greater than the array's
+	  maximum index so things like ${x[@}: -1} work to give the last element
+	  (requires fixing array tests)
+
+builtins/common.c
+	- new error function, sh_wrerror(),  for builtins to call when a write
+	  error occurs
+
+builtins/common.h
+	- extern declaration for sh_wrerror()
+
+builtins/cd.def
+	- change builtin_error call to use sh_wrerror()
+
+builtins/echo.def
+	- report write errors with sh_wrerror() instead of just returning
+	  failure
+
+builtins/printf.def
+	- change printstr to return failure (-1) or success (0) indication
+	  rather than void
+	- report write errors when printstr() fails, return failure
+	- if any of the PF/printf calls fail, report write error and return
+	  failure
+
+execute_cmd.c
+	- change execute_in_subshell so the subshell command inherits the
+	  command timing flags from the enclosing COMMAND *
+
+				   9/11
+				   ----
+[prayers for the victims of 9/11/2001]
+
+lib/sh/strnlen.c
+	- new file, implementation of GNU libc extension function strnlen
+
+lib/sh/Makefile.in, {config.h,configure,Makefile}.in, MANIFEST
+	- changes for strnlen
+
+configure.in
+	- version changed to 3.1-devel
+
+doc/bash.1, lib/readline/doc/rluser.texi
+	- added description of `-o plusdirs' to complete/compgen (thanks,
+	  Arnold)
+
+parse.y
+	- new parser_state flag, PST_ASSIGNOK, if set indicates we're parsing
+	  arguments to a builtin that accepts assignment statement arguments
+	- turn on PST_ASSIGNOK in read_token_word when appropriate
+	- turn off PST_ASSIGNOK in read_token when appropriate
+	- don't attempt to parse a compound assignment specially unless we're
+	  in a position where an assignment statement is acceptable, or
+	  PST_ASSIGNOK is set
+
+				   9/13
+				   ----
+variables.c
+	- make BASH_ARGC, BASH_ARGV, BASH_LINENO, and BASH_SOURCE
+	  non-unsettable, since the shell uses those values internally
+
+expr.c
+	- make exponentiation right-associative, as is apparently correct
+
+				   9/16
+				   ----
+arrayfunc.c
+	- make sure convert_var_to_array marks the environment as needing
+	  recreation if the converted variable was exported
+
+				   9/17
+				   ----
+braces.c
+	- mark ${ as introducing an additional level of braces only if it's
+	  not in a quoted string -- quoted strings are handled before brace
+	  matching is done
+
+parse.y
+	- fixed an obscure problem in history_delimiting_chars where the `in'
+	  in a case statement could have a semicolon added after it, if the
+	  `case word' was on a previous line
+
+support/config.guess
+	- support for newest versions of tandem non-stop kernel
+
+lib/readline/display.c
+	- in compute_lcd_of_matches, explicitly cast `text' to `char *' before
+	  passing it to rl_filename_dequoting_function
+
+lib/readline/terminal.c
+	- bind the key sequence sent by the keypad `delete' key to delete-char
+	  (same as ^D in emacs mode)
+
+builtins/ulimit.def
+	- in print_all_limits, don't print anything if get_limit returns
+	  -1/EINVAL, indicating that the kernel doesn't support that particular
+	  limit
+	- add -i (max number of pending signals), -q (max size of posix msg
+	  queues), -x (max number of file locks) for systems (Linux) that
+	  support them
+
+doc/{bash.1,bashref.texi}
+	- fix description of correspondence between FUNCNAME, BASH_LINENO,
+	  and BASH_SOURCE indices in description of BASH_LINENO
+
+				   9/18
+				   ----
+lib/sh/shquote.c
+	- don't quote CTLESC and CTLNUL with CTLESC in sh_backslash_quote, as
+	  long as the resultant string never gets sent to the word expansion
+	  functions without going through the shell parser
+
+externs.h
+	- add extern declarations for strnlen and strpbkrk from lib/sh
+
+subst.[ch]
+	- changes to handle case where IFS consists of multibyte characters.
+	  Changed: string_extract_verbatim, split_at_delims,
+	  string_list_dollar_star, string_list_dollar_at, list_string,
+	  get_word_from_string, setifs
+
+				   9/19
+				   ----
+mailcheck.c
+	- change file_mod_date_changed to reset the cached mail file data if
+	  the file size drops to zero
+
+lib/readline/complete.c
+	- change append_to_match so that a non-zero value for
+	  rl_completion_suppress_append will cause no `/' to be appended to a
+	  directory name
+
+bashline.c
+	- experimental change to suppress appending a slash for a completed
+	  filename that is found in PATH as well as a directory in the current
+	  directory under certain circumstances:  a single instance found in
+	  $PATH when `.' is not in $PATH, and multiple instances found in the
+	  $PATH, even when `.' is in the $PATH
+
+				   9/24
+				   ----
+command.h
+	- new word flag: W_ASSIGNRHS, means word is rhs of assignment statement
+	- new word flag: W_NOTILDE, means word is not to be tilde expanded
+	- new word flag (internal): W_ITILDE, means the next character is a
+	  tilde that should be expanded
+
+general.c
+	- new set of tilde suffixes for use when parsing the RHS of an
+	  assignment statement and =~ should not be subject to tilde expansion
+	- if ASSIGN_P argument to bash_tilde_expand is 2, use tilde prefixes
+	  for parsing RHS of assignment statement
+
+general.[ch]
+	- new function bash_tilde_find_word, drop-in replacement for
+	  tilde_find_word
+
+subst.c
+	- call bash_tilde_expand with secord argument of 2 when expanding rhs
+	  of an assignment statement, so tildes after second and subsequent
+	  `=' in an assignment are not expanded
+	- new function, expand_string_assignment, to expand the rhs of an
+	  assignment statement
+	- add `~' to EXP_CHAR, the characters that will cause the word
+	  expansion functions to be called
+	- move tilde expansion into expand_word_internal instead of many
+	  different calls to bash_tilde_expand scattered across different
+	  functions.  NOTE:  This means that double quotes surrounding a
+	  {paramOPword} expansion will cause tilde expansion to NOT be
+	  performed on `word'.  I think this is right, what POSIX specifies,
+	  and consistent with the behavior of other characters in the rhs
+
+execute_cmd.c
+	- take out calls to bash_tilde_expand before calling word expansion
+	  functions
+
+				   9/26
+				   ----
+execute_cmd.c
+	- make sure to call UNBLOCK_CHILD before returning on a pipe creation
+	  failure in execute_pipeline
+
+				   9/27
+				   ----
+variables.c
+	- change get_bash_command to deal with the_printed_command_except_trap
+	  being NULL
+
+execute_cmd.c
+	- fix execute_simple_command to deal with the_printed_command being
+	  NULL when assigning to the_printed_command_except_trap -- fixes
+	  seg fault in savestring()
+
+parse.y
+	- change the parser so that the closing `)' in a compound variable
+	  assignment delimits a token -- ksh93 does it this way
+
+doc/{bash.1,bashref.texi}
+	- change description of tilde expansion to note that expansion is
+	  attempted only after the first =~ in an assignment statement
+
+builtins/declare.def
+	- when assigning to an array variable with declare -a x=(...), make
+	  sure the last character in the rhs  of the variable assignment is
+	  `)', not just that it appears somewhere
+
+				   9/28
+				   ----
+command.h
+	- add a `W_NOEXPAND' flag to inhibit all expansion except quote removal
+	- add a `W_COMPASSIGN' flag to denote a word is a compound assignment
+	  statement
+
+parse.y
+	- set W_COMPASSIGN on words that appear to be compound assignments
+
+subst.c
+	- pass W_NOXPAND and W_COMPASSIGN through end of expand_word_internal
+
+subst.[ch]
+	- new function, expand_assignment_string_to_string, calls
+	  expand_string_assignment and then string_list on the result
+
+variables.c
+	- assign_in_env now calls expand_assignment_string_to_string
+
+				   9/30
+				   ----
+builtins/common.c
+	- change get_job_spec so the null job `%' once again means the current
+	  job
+
+				   10/1
+				   ----
+subst.c
+	- do_assignment_internal now takes a WORD_DESC * as its first
+	  argument, and uses its `word' member as the assignment string
+	- change expand_word_list_internal to call do_word_assignment instead
+	  of do_assignment, passing it `word' instead of, e.g., `word->word'
+	- change extract_array_assignment_list to just return the passed
+	  string minus a trailing `)' if the last character is a right
+	  paren
+	- change do_assignment_internal to call extract_array_assignment_list
+
+subst.[ch]
+	- change do_assignment and do_assignment_no_expand to take a `char *'
+	  instead of `const char *' first argument; change extern prototypes
+	- new function, do_word_assignment, takes a WORD_DESC * and calls
+	  do_assignment_internal on it; add extern declaration with prototype
+
+general.h
+	- new typedef, sh_wassign_func_t, like sh_assign_func_t but takes a
+	  WORD_DESC * as its first argument
+
+variables.[ch]
+	- assign_in_env now takes a WORD_DESC * as its first argument
+
+				   10/2
+				   ----
+command.h
+	- new word flag, W_ASSNBLTIN, denotes that the word is a builtin
+	  command (in a command position) that takes assignment statements
+	  as arguments, like `declare'
+	- new word flags, W_ASSIGNARG, denotes that word is an assignment
+	  statement given as argument to assignment builtin
+
+execute_cmd.c
+	- set W_ASSNBLTIN flag in fix_assignment_words if necessary (if there
+	  are any arguments that are assignment statements)
+	- set W_ASSIGNARG flag in fix_assignment_words if necessary
+
+subst.c
+	- new function, do_compound_assignment, encapsulates the necessary
+	  code to perform a compound array assignment (including creation of
+	  local variables); called from do_assignment_internal
+	- to fix the double-expansion problem with compound array assignments
+	  that are arguments to builtins like `declare', changed
+	  shell_expand_word_list to treat those arguments like assignment
+	  statements (with proper creation of local variables inside shell
+	  functions) and pass the attribute-setting portion of the statement
+	  onto the builtin.  This is what ksh93 appears to do, from inspection
+	  of the `ksh93 -x' output
+
+execute_cmd.c
+	- fix execute_simple_command:  in case of pipeline or async command,
+	  when forking early, set `subshell_environment' so that it can contain
+	  both SUBSHELL_PIPE and SUBSHELL_ASYNC -- the two should not be
+	  mutually exclusive.  Fixes bug reported by pierre.humblet@ieee.org
+	- remove references to last_pid, old_command_subst_pid; use NO_PID as
+	  a sentinel value to decide whether or not a child process has been
+	  created and needs to be waited for.  Submitted by
+	  pierre.humblet@ieee.org to fix recycling-pid problem on cygwin
+
+doc/{bash.1,bashref.texi}
+	- fixed documentation of `@(pattern)' extended globbing operator --
+	  it succeeds if the string matches one of the patterns, not exactly
+	  one.  This is what ksh93 does, too
+
+lib/readline/complete.c
+	- fixed rl_menu_complete so that a negative argument cycles backwards
+	  through the list

+support/shobj-conf
+	- additions for System V.5 from Boyd Gerber <gerberb@zenez.com>
+
+subst.c
+	- in command_substitute, if subshell_environment includes
+	  SUBSHELL_ASYNC, call make_child with the `async_p' argument set to
+	  non-zero.  This keeps command substitutions for async commands or
+	  pipelines from trying to give the terminal back to the shell's
+	  pgrp.  make sure to save and restore last_asynchronous_pid.  Fix
+	  suggested by <pierre.humblet@ieee.org>

+	  defined but rejected as invalid by waitpid(2)
+
+configure.in
+	- add call to BASH_CHECK_WCONTINUED, defines WCONTINUED_BROKEN
+
+redir.c
+	- experimental change to add_undo_redirect to save manipulations to
+	  file descriptors >= SHELL_FD_BASE (10) on the list of redirections
+	  to be undone even if `exec' causes the list to be discarded
+
+doc/{bash.1,bashref.texi}
+	- note that redirections using file descriptors > 9 should be used

+
+				   10/19
+				   -----
+variables.c
+	- change push_exported_var so that a tempenv variable has to have the
+	  export attribute set (which they all do -- something to look at) and
+	  the `propagate' attribute set to be propagated down to the next
+	  scope
+
+execute_cmd.c
+	- change execute_builtin so that if CMD_COMMAND_BUILTIN is set in the
+	  passed flags argument, call pop_scope with a value that says the
+	  builtin is not special, since `command' means that preceding variable
+	  assignments don't persist in the environment.  Fixes problem with
+	  variable assignments preceding command preceding special builtin
+	  keeping those variable assignments around (when in posix mode)
+
+				   10/20

+lib/sh/shquote.c

+
+externs.h
+	- new extern declaration for sh_mkdoublequoted
+
+parse.y
+	- use sh_mkdoublequoted after calling localeexpand()
+
+lib/sh/strtrans.c
+	- change ansicstr to understand that  (flags & 4) != 0 means to remove
+	  backslash from unrecognized escape sequences
+
+general.c
+	- fix logic problem in assignment() that caused non-variable-starter
+	  characters to be allowed, resulting in things like `1=xxx' creating
+	  a variable `1' in the hash table

+lib/readline/util.c
+	- include rlmbutil.h for multibyte definitions

+
+lib/readline/rlmbutil.h
+	- extern defines for _rl_walphabetic and _rl_char_value for when
+	  multibyte chars are not being used

+	  _rl_find_prev_mbchar (MB_PREVCHAR) that try to avoid unneeded
+	  function calls
+
+lib/readline/text.c
+	- fix rl_foward_word to work with multibyte characters (or in a

+				   -----
+lib/glob/glob.c
+	- after some (compiled-in) threshold, glob_vector will stop using

+	  malloc, with appropriate cleanup before returning
+
+subst.c
+	- don't expand tildes after `=' in expand_word_internal, even if the

+	  marked W_ASSIGNMENT
+
+				   10/31

+
+shell.c
+	- make sure shell_is_restricted skips over a single leading `-' in

+
+lib/readline/histexpand.c
+	- fix a problem with finding the delimiter of a `?' substring when
+	  compiled for multibyte characters (from SUSE, but not sent in)
+
+				   11/1
+				   ----
+lib/readline/display.c
+	- correct some assignments to _rl_last_c_pos:  when in a multibyte
+	  locale, it's used as an absolute cursor position; when not using
+	  multibyte characters, it's a buffer offset.  I should have caught
+	  this when the multibyte character support was donated
+
+				   11/5
+				   ----
+general.c
+	- change `assignment()' to accept `+=' assignment operator
+
+arrayfunc.[ch]
+	- bind_array_variable and assign_array_element both take a new `flags'
+	  argument
+	- assign_array_var_from_string, assign_array_from_string, and
+	  assign_array_var_from_word_list now all take a new `flags' argument
+	- change assign_array_var_from_word_list to understand how to append
+	  to an array variable
+	- change assign_array_var_from_string to understand how to append
+	  to an array variable.  It does not unset the previous value if
+	  appending, allowing both old values to be changed and new ones to
+	  be added
+
+subst.h
+	- new flag #defines to use for evaluating assignment statements
+
+{subst,variables}.c, builtins/{declare,read}.def
+	- change callers of assign_array_element and bind_array_variable
+	- change do_compound_assignment to understand assignment flags

+
+pcomplete.c,builtins/{declare,read}.def

+	- change bind_variable_internal to pass assignment flags on to
+	  make_variable_value
+	- change assign_in_env to treat `var+=value' like `var=value'
+
+arrayfunc.c
+	- break code that actually constructs the new value and assigns it
+	  to a particular array index out into a new functions:
+	  bind_array_var_internal.  This fakes out make_variable_value by

+	  they were `standalone' assignment statements array assignment words
+	  of the form [ind]+=val
+
+				   11/7
+				   ----
+builtins/declare.def
+	- added support for `declare [flags] var+=value'.  `Flags' are applied
+	  before the assignment is performed, which has implications for things
+	  like `-i' -- if -i is supplied, arithmetic evaluation and increment
+	  will be performed
+
+builtins/setattr.def
+	- add support for `+=' assignment for rest of `assignment builtins':
+	  export, readonly
+
+				   11/12
+				   -----
+lib/readline/display.c
+	- make sure prompt_physical_chars and prompt_invis_chars_first_line

+
+				   11/19
+				   -----
+redir.c
+	- slightly change do_redirection_internal to set the close-on-exec
+	  flag for file descriptors > 2 used to save file descriptors < 2
+	  using explicit redirections (e.g., `exec 3>&1').  This keeps file
+	  descriptors pointing to pipes from being left open but doesn't

+doc/{bash.1,bashref.texi}

+
+				   11/22
+				   -----
+doc/bash.1,lib/readline/doc/{readline.3,rluser.texi}
+	- documented detail that yank-last-arg and yank-nth-arg use the history
+	  arg expansion code (and, as a result, are subject to restrictions
+	  of the history-comment character)
+
+				   11/23
+				   -----
+execute_cmd.c
+	- changes so that BASH_COMMAND preserves its value into a DEBUG trap:
+	  for commands, arithmetic for command expressions, select commands,
+	  case commands, (( commands, [[ commands, simple commands
+
+				   11/24
+				   -----
+doc/{bash.1,bashref.texi}
+	- changed description of `set' builtin slightly so that it is clear
+	  that only variables are displayed in posix mode and that read-only
+	  variables can't be reset by simply sourcing the output of `set'
+
+lib/sh/strftime.c
+	- don't try to redefine `inline' if it's already defined
+
+				   11/26

+builtins/evalfile.c
+	- make same changes as 11/26, this time to _evalfile
+
+execute_cmd.c
+	- change execute_function to run the return trap after a function

+				   -----
+lib/readline/misc.c
+	- fix memory leaks in _rl_free_history_entry and rl_maybe_replace_line

+	- make sure timestamp is initialized to NULL in rl_maybe_save_line
+
+				   12/1

+execute_cmd.c
+	- fix execute_function so a function calling `return' will run the

+
+doc/{bash.1,bashref.texi}
+	- fix description of RETURN trap in various places to indicate that it's
+	  only inherited by shell functions if function tracing is on globally
+	  or has been enabled for that function
+	- fix documentation to indicate that the DEBUG and RETURN traps are
+	  inherited under the same conditions
+
+execute_cmd.c
+	- a function does not inherit the RETURN trap if a DEBUG trap is

+				   ----
+subst.c

+subst.c
+	- fixed a typo in string_extract_verbatim in first call to MBLEN
+	  (used `slen - 1' instead of `slen - i')
+
+				   12/17
+				   -----
+subst.c
+	- avoid some calls to strlen if the value is only being used for
+	  ADVANCE_CHAR and MB_CUR_MAX == 1 (since ADVANCE_CHAR doesn't need
+	  it unless multibyte characters are possible)
+	- change string_extract_verbatim so it takes the length of the string
+	  as a parameter, so we don't have to recompute the length of the same
+	  string over and over again when doing word splitting (that kills if
+	  it's a long string)
+
+				   12/18

+subst.c

+doc/{bash.1,bashref.texi}

+
+				   12/28
+				   -----
+shell.c
+	- set gnu_error_format to 1 if running under emacs.  This should allow
+	  the emacs `next-error' stuff to work, at least for interactive shells
+
+parse.y
+	- change yy_stream_get to set interrupt_immediately before calling
+	  getc_with_restart when the shell is interactive.  This avoids the
+	  synchronization problem caused by the call to QUIT in read_a_line,
+	  which results in the first character after a SIGINT/^C to be
+	  dropped
+
+				   12/30
+				   -----
+builtins/mkbuiltins.c
+	- changes to write long documentation to arrays as a single string by
+	  default, rather than an array of strings -- enabled by default
+	- new option, -S, to restore old behavior of writing multiple strings
+	  for long documentation
+	- changes to avoid filenames written when the separate-filenames option
+	  (-H) has been supplied being run through gettext
+
+configure.in
+	- new cofiguration option, --enable-single-help-strings (on by default),
+	  causes help text to be stored as a single string (or smaller set than
+	  one string per line)
+
+builtins/Makefile.in
+	- pass `-S' to mkbuiltins if single-help-strings is turned off
+
+doc/bashref.texi
+	- documented new `single-help-strings' configure option
+
+				 1/3/2005
+				 --------
+jobs.c
+	- make wait_for return a non-zero status if the job or processed
+	  waited for is suspended.  Returns 128 + stop signal.  This fixes

+	  `two' after the sleep is suspended
+
+				    1/5
+				    ---
+print_cmd.c

+	  the first byte
+
+				    1/8
+				    ---
+variables.c
+	- new special variable hook function for COMP_WORDBREAKS; sets
+	  rl_completer_word_break_characters back to NULL when the variable
+	  is unset
+	- change bind_variable_value to understand dynamic variables with
+	  assign_function set, and handle them correctly.  If the variable is
+	  being appended to, use make_variable_value to create the new
+	  value
+	- change bind_variable_internal to understand dynamic variables with
+	  assign_function set, and handle them the same way
+	- RANDOM and LINENO now get the integer attribute, so appending works
+	  as expected
+	- ditto for HISTCMD, MAILCHECK, OPTIND
+
+lib/readline/display.c
+	- change _rl_make_prompt_for_search to set prompt_physical_chars
+	  appropriately
+	- rl_save_prompt and rl_restore_prompt save and restore
+	  prompt_prefix_length
+	- change redraw_prompt to use rl_save_prompt and rl_restore_prompt
+	- change rl_restore_prompt to set the `save' variables back to
+	  NULL/0 so code can check whether or not the prompt has been saved
+	- change rl_message and rl_clear_message to save and restore the
+	  prompt if the caller has not already done it (using a simple
+	  semaphore-like variable)
+	- change rl_message to call expand_prompt, so that local_prompt and
+	  local_prompt prefix are set before calling the redisplay functions,
+	  in case the prompt is longer than a screenwidth (fixes bug
+	  reported to debian by epl@unimelb.edu.au)
+
+lib/readline/doc/rltech.texi
+	- make sure to note that rl_save_prompt should be called before
+	  rl_message, and rl_restore_prompt before rl_clear_message
+
+pcomplete.c
+	- make sure to save and restore the parser state around the call to
+	  execute_shell_function in gen_shell_function_matches.  Fixes bug
+	  reported by a050106.1.keeLae3x@captaincrumb.com (cute)
+
+lib/readline/readline.c
+	- fix _rl_dispatch_subseq in the case where we're recursing back up
+	  the chain (r == -2) and we encounter a key shadowed by a keymap,
+	  but originally bound to self-insert.  Calling rl_dispatch with
+	  ANYOTHERKEY as the first argument will call rl_insert, but with
+	  ANYOTHERKEY (256) as the char to insert.  Use the shadow keymap
+	  and set things up to dispatch to rl_insert with the shadowed key

+	- changes to pass W_HASQUOTEDNULL flag out of expand_word_internal;
+	  changed callers to call remove_quoted_nulls only if return value has
+	  W_HASQUOTEDNULL set.  This is a mostly-complete fix for the
+	  long-standing CTLNUL confusion between a quoted null expansion and

+dispose_cmd.c
+	- set w->word to 0 before putting a WORD_DESC * back in the cache in
+	  dispose_word_desc; changed callers to delete those assignments
+
+variables.c
+	- change assign_random and get_random_value so that the random number
+	  generator only gets re-seeded once in a subshell environment, and
+	  assigning a value to RANDOM counts as seeding the generator.  This
+	  makes the sequences a little more predictable

+lib/sh/netconn.c
+	- fix isnetconn() to understand that getpeername can return ENOTCONN
+	  to indicate that an fd is not a socket
+
+configure.in
+	- set BUILD_DIR to contain backslashes to escape any spaces in the
+	  directory name -- this is what make will accept in targets and
+	  prerequisites, so it's better than trying to use double quotes
+	- set SIZE to the appropriate value if some cross-compiling tool
+	  chain is being used; `size' by default (can be overridden by
+	  SIZE environment variable)
+
+Makefile.in
+	- use $(SIZE) instead of size; set SIZE from configure

+jobs.h

+
+				    2/2
+				    ---
+
+jobs.[ch]
+	- change PRUNNING to PALIVE
+	- new define INVALID_JOB
+	- new macro get_job_by_jid(ind), currently expands to jobs[ind]
+	- new define J_JOBSTATE, operates on a JOB * like JOBSTATE operates on
+	  a job index
+	- new function, reset_job_indices, called from delete_job if
+	  js.j_lastj or js.j_firstj are removed
+	- change various functions to keep counters and stats in struct jobstats
+
+pcomplete.c, builtins/common.c, builtins/{exit,fg_bg,jobs,kill,wait}.def
+	- change global variables (e.g., job_slots) to struct members
+	  (e.g., js.j_jobslots)
+	- use INVALID_JOB define where appropriate
+	- use get_job_by_jid and J_JOBSTATE where appropriate
+
+trap.c
+	- change reset_or_restore_signal_handler to not free the exit trap
+	  string if the function pointer is reset_signal, which is used when
+	  the trap strings shouldn't be freed, like in command substitution
+
+				    2/4
+				    ---
+jobs.c
+	- new function, realloc_jobs_list, copies jobs array to newly-allocated
+	  memory shrinking (or growing) size to have next multiple of JOB_SLOTS
+	  greater than js.j_njobs
+	- change compact_jobs_list to just call reap_dead_jobs and then
+	  realloc_jobs_list, simplifying it considerably
+	- discard_pipeline now returns `int':  the number of processes freed
+	- slightly changed the logic deciding whether or not to call
+	  compact_jobs_list:  now non-interactive shells will compact the
+	  list if it reaches MAX_JOBS_IN_ARRAY in size
+
+parse.y
+	- move test for backslash-newline after pop_string in shell_getc so

+
+				    2/8

+jobs.h
+	- new structs for holding status of exited background processes, as

+	- new job flag: J_ASYNC
+
+jobs.c
+	- new functions to manipulate struct holding status of exited
+	  background processes
+	- new members in struct jobstats to hold pointer to last created job
+	  and last created asynchronous job
+	- initialize js.c_childmax in initialize_job_control
+	- if the `async' arg to stop_pipeline is non-null, set the J_ASYNC
+	  flag in the job struct
+	- set js.j_last_made_job and js.j_last_asynchronous_job in
+	  stop_pipeline
+	- new function: find_last_proc, returns the PROCESS * to the last proc
+	  in a job's pipeline
+	- changed find_last_pid to call find_last_proc
+	- change delete_job to call bgp_add on the last proc of the job being

+jobs.h
+	- add support for PS_RECYCLED as a process state, add PRECYCLED macro
+	  to test it.  Change PALIVE and PRUNNING macros to not count processes
+	  in PS_RECYCLED state
+
+execute_cmd.c
+	- restore use of last_pid as sentinel value; use NO_PID as sentinel
+	  only if RECYCLES_PIDS is defined
+
+jobs.c
+	- change find_job to return a pointer to the PROCESS the desired pid
+	  belongs to, analogous to find_pipeline returning pointer to JOB
+	- change find_job callers to add extra argument
+	- change running_only arguments to find_pipeline and find_job to
+	  alive_only, since we don't want recycled pids returned here and it
+	  better describes the result
+	- new function find_process, calls find_pipeline and searches the
+	  returned pipeline for the PROCESS * describing the desired pid
+	- in make_child, if fork() returns the same pid as the value of
+	  last_asynchronous_pid when RECYCLES_PIDS is defined, avoid pid
+	  aliasing by resetting last_asynchronous_pid to 1
+	- use PRUNNING instead of child->running, since we, for the most
+	  part, don't want to consider recycled pids (e.g., in make_child())
+	- call find_process instead of find_pipeline in waitchld()
+	- use PEXITED(p) instead of testing p->running == PS_DONE
+	- in make_child, call bgp_delete to remove a just-created pid from the
+	  last of saved pid statuses
+	- in add_process, check whether or not pid being added is already in
+	  the_pipeline or the jobs list (using find_process) and mark it as
+	  recycled if so
+	- This set of fixes mostly came from Pierre Humblet
+	  <pierre.humblet@ieee.org> to fix pid aliasing and reuse problems on

+
+doc/bashref.texi

+subst.c
+	- change list_string and get_word_from_string to explicitly treat an
+	  IFS character that is not space, tab, or newline *and any adjacent
+	  IFS white space* as a single delimiter, as SUSv3/XPG6 says
+
+builtins/read.def
+	- check whether or not the number of fields is exactly the same as
+	  the number of variables instead of just assigning the rest of the
+	  line (minus any trailing IFS white space) to the last variable.
+	  This parses a field and checks whether or not it consumes all of
+	  the input (including any trailing field delimiters), falling back
+	  to the previous behavior if it does not.  This is what POSIX.2
+	  specifies, I believe (and the consensus of the austin-group list).
+	  This requires a few tests in read.tests to be changed: backslashes
+	  escaping IFS whitespace characters at the end of input cause the
+	  whitespace characters to be preserved in the value assigned to the
+	  variable, and the trailing non-whitespace field delimiter issue

+builtins/read.def
+	- when testing for a pipe, use `fd' instead of hard-coding 0, since we

+	- convert PF macro to use asprintf into a local buffer
+	  Preparation for printf -v var
+	- add code to add the text printed to a `variable buffer' if -v option
+	  supplied.  The buffer grows as needed
+	- printf now takes a `-v var' option to put the output into the variable
+	  VAR rather than sending it to stdout.  It does not:

+lib/sh/snprintf.c
+	- fix * code to deal with a negative precision by treating it as if

+	- fix format parsing code to deal with a negative inline precision,
+	  e.g., "%4.-4f" by treating it as if the `'. and any digit string in

+
+lib/readline/vi_mode.c

+lib/readline/macro.c
+	- use a slightly different strategy upon encountering the end of a macro
+	  when using the callback interface:  when the last character of a

+builtins/fc.def
+	- fixed a typo when using POSIX_FC_EDIT_COMMAND
+
+redir.h
+	- new flag values for redirections: RX_INTERNAL and RX_USER (currently
+	  unused)
+
+redir.c
+	- add_undo_redirect and add_undo_close_redirect now set RX_INTERNAL
+	  flag when making new redirects
+	- in do_redirection_internal, only set file descriptors > 2 to CLEXEC
+	  if they're marked as RX_INTERNAL
+
+				   10/12
+				   -----
+jobs.c
+	- in wait_for_single_pid, if in posix mode, remove the waited-for pid
+	  from the list of background pids, forgetting it entirely.  POSIX
+	  conformance tests test for this.
+
+lib/readline/{readline.h,vi_mode.c}
+	- new state flag, RL_STATE_VICMDONCE, set after entering vi command
+	  mode the first time; reset on each call to readline()
+
+				   10/13
+				   -----
+lib/readline/undo.c
+	- in rl_revert_line, make sure that revert-line in vi mode leaves
+	  rl_point set to 0 no matter the state of the line buffer
+
+lib/readline/vi_mode.c
+	- when entering vi_command mode for the first time, free any existing
+	  undo list so the previous insertions won't be undone by the `U'
+	  command.  This is how POSIX.2 says `U' should work (and the test
+	  suite tests for it)
+
+lib/readline/bind.c
+	- change rl_parse_and_bind so only `set' commands involving boolean
+	  readline variables have trailing whitespace stripped from the value

+	  lib/sh/winsize.c, made function global
+
+{jobs,nojobs,sig}.c,{jobs,sig}.h
+	- moved SIGWINCH handling code to sig.c rather than duplicate it in
+	  jobs.c and nojobs.c
+	- call set_sigwinch_handler from sig.c code rather than job control
+	  signal initialization
+
+sig.[ch]
+	- new variable, sigwinch_received, acts like interrupt_state for
+	  SIGWINCH, set by sigwinch_sighandler.  sigwinch_sighandler no longer
+	  calls get_new_window_size
+
+parse.y
+	- add call to get_new_window_size if sigwinch_received at top of
+	  shell_getc
+
+				   10/19
+				   -----
+lib/malloc/malloc.c
+	- to avoid orphaning memory on free if the right bucket is busy, use a
+	  new function xplit(mem, bucket) to split the block into two or more
+	  smaller ones and add those to the right bucket (appropriately marking
+	  it as busy)
+	- audit bsplit(), bcoalesce(), and xsplit() for proper use of busy[],
+	  since they're dealing with two separate buckets
+
+				   10/22
+				   -----
+subst.c
+	- new flag for string_extract: EX_REQMATCH, means to return an error
+	  if a matching/closing character is not found before EOS
+	- new static flag variables: extract_string_error and extract_string_fatal
+	- change expand_word_internal to check for new error returns from
+	  string_extract and return errors if appropriate
+
+				   10/23
+				   -----
+builtins/cd.def

+execute_cmd.c
+	- make sure a DEBUG trap doesn't overwrite a command string passed to

+
+bashline.c

+
+				   11/6
+				   ----
+lib/readline/display.c
+	- when deciding where to move the cursor in rl_redisplay and needing
+	  to move the cursor back after moving it vertically and compensate
+	  for invisible characters in the prompt string, make sure that
+	  _rl_last_c_pos is treated as an absolute cursor position in a

+
+				   11/11
+				   -----
+
+lib/readline/terminal.c
+	- new function, rl_reset_screen_size, calls _rl_get_screen_size to
+	  reset readline's idea of the terminal size
+	- don't call _rl_get_screen_size in _rl_init_terminal_io if both	
+	  _rl_screenheight and _rl_screenwidth are > 0
+	- don't initialize _rl_screenheight and _rl_screenwidth to 0 in
+	  _rl_init_terminal_io; let caller take care of it
+	- set _rl_screenheight and _rl_screenwidth to 0 before calling
+	  _rl_init_terminal_io
+
+lib/readline/readline.h
+	- new extern declaration for rl_reset_screen_size
+
+lib/readline/doc/rltech.texi
+	- documented rl_reset_screen_size
+
+variables.c
+	- if readline is being used, compile in a special var function for
+	  assignments to LINES and COLUMNS that calls rl_set_screen_size or
+	  rl_reset_screen_size as appropriate.  Only do this in posix mode
+	  and only when STRICT_POSIX is defined at compile time
+	- new semaphore variable, winsize_assignment, set while doing an
+	  assignment to LINES or COLUMNS
+	- new variable, winsize_assigned, says LINES or COLUMNS was assigned
+	  to or found in the environment
+	- if in the middle of an assignment to LINES or COLUMNS, make
+	  sh_set_lines_and_columns a no-op
+
+lib/sh/winsize.c
+	- get_new_window_size now takes two int * arguments, to return the
+	  screen dimensions
+
+externs.h
+	- change extern declaration for get_new_window_size
+
+{jobs,nojobs}.c, parse.y
+	- change callers of get_new_window_size
+
+				   11/12

+
+lib/readline/readline.h
+	- extern declaration for rl_prefer_env_winsize
+
+lib/readline/doc/rltech.texi
+	- document rl_prefer_env_winsize

+				   -----
+lib/readline/rltty.c
+	- change rl_prep_terminal to make sure we set and reset the tty

+	  command mode
+
+				   11/14

+lib/readline/display.c
+	- changes to rl_redisplay to compensate for update_line updating
+	  _rl_last_c_pos without taking invisible characters in the line into
+	  account.  Important in multibyte locales where _rl_last_c_pos is an
+	  absolute cursor position
+	- changes to _rl_move_cursor_relative to account for _rl_last_c_pos
+	  being an absolute cursor position in a multibyte character locale
+	- rewrote _rl_move_cursor_relative to make it a little simpler
+
+				   11/29
+				   -----
+lib/readline/display.c
+	- changes to rl_redisplay and update_line for update_line to communicate
+	  upward that it took the number of invisible characters on the current
+	  line into account when modifying _rl_last_c_pos
+	- in update_line, adjust _rl_last_c_pos by wrap_offset before calling
+	  _rl_move_cursor_relative, so we pass correct information about the

+				   -----
+lib/readline/text.c

+	- ditto for return value of rl_delete_text
+
+lib/readline/readline.c
+	- don't return the value of the called readline function as the return
+	  value from _rl_dispatch_subseq; -1 means something different to the

+
+execute_cmd.c

+aclocal.m4
+	- add check for wctype() to BASH_CHECK_MULTIBYTE, define HAVE_WCTYPE
+
+config.h.in
+	- add HAVE_WCTYPE #define

+config-bot.h
+	- add HAVE_WCTYPE to the set of checks for HANDLE_MULTIBYTE.  This

+
+				   12/20
+				   -----
+lib/readline/display.c
+	- don't treat RL_PROMPT_START_IGNORE specially inside a sequence of

+				   -----
+subst.c
+	- change expand_word_internal to process rest of `tilde-word' as a

+	  more intuitive, and is effectively what bash-3.0 did
+
+				   12/23

+subst.c
+	- when making a local array variable in do_compound_assignment, make

+
+doc/bash.1
+	- documented expansions for word and patterns in case statement

+
+lib/readline/{bind,callback,display,isearch,rltty,search,text,vi_mode}.c

+lib/readline/bind.c
+	- fix rl_translate_keyseq bad translation of \M-\C-x sequences
+
+execute_cmd.c
+	- in execute_arith_command, if the expression expands to more than one
+	  word, make sure we join the words into a single string and pass the

+
+expr.c
+	- new functions: _is_arithop(c), returns true if C is a valid single-
+	  character arithmetic operator; _is_multiop(c), returns true if C is
+	  a token corresponding to a valid multi-character arithmetic operator
+	- if we encounter a character that isn't a valid arithmetic
+	  operator, throw an error.  Try to be intelligent about what type of
+	  error message to print
+
+subst.c
+	- new function, expand_arith_string, calls expand_string_if_necessary;
+	  used where an arithmetic expression needs to be expanded
+
+subst.h
+	- new extern declaration for expand_arith_string
+
+arrayfunc.c
+	- in array_expand_index, call expand_arith_string to expand the
+	  subscript in a fashion consistent with other arithmetic expressions
+
+subst.c
+	- fix parameter_brace_patsub so that we don't try to anchor the pattern
+	  at the beginning or end of the string if we're doing global
+	  replacement -- that combination doesn't doesn't make sense, and
+	  the changed behavior is compatible with ksh93
+
+doc/{bash.1,bashref.texi}
+	- changed description of pattern substitution to match the new

+support/signames.c
+	- new file, initialize_signames() function from old mksignames.c.  This
+	  file builds the signal_names array
+
+support/mksignames.c
+	- strip out initialize_signames(), move to signames.c.  This file only
+	  writes signames.h
+	- set up to only write a stub signames.h if CROSS_COMPILING is defined,
+	  with extern declaration for initialize_signames
+	- if not cross compiling, #define initialize_signames to nothing
+
+Makefile.in
+	- mksignames is now linked from mksignames.o and buildsignames.o
+	- add rules to build signames.o, assuming we're building it as part
+	  of the shell (cross-compiling)
+
+trap.c
+	- call initialize_signames from initialize_traps
+
+configure.in
+	- set SIGNAMES_O to nothing (normal) or signames.o (cross-compiling),
+	  substitute into Makefile
+	- don't set SIGNAMES_H if cross-compiling any more
+
+				   12/30

+
+subst.c
+	- change expand_word_internal to suppress process substitution if the
+	  word has the W_NOPROCSUB flag
+
+shell.c
+	- --wordexp turns on W_NOPROCSUB in addition to W_NOCOMSUB
+
+subst.c
+	- change string_list_dollar_at and string_list_dollar_star so that
+	  MB_CUR_MAX is used to size an array only when using gcc, since gcc
+	  can handle non-constant array sizes using a mechanism like alloca.
+	  Other compilers, e.g. Sun's compiler, do not implement that
+	  extension
+
+				   12/31
+				   -----
+builtins/mkbuiltins.c
+	- when cross-compiling, don't include <config.h>, since it's for the
+	  target rather than the host system.  Instead, choose a reasonable
+	  set of default #defines based on a minimal POSIX system
+
+jobs.c
+	- change find_process to handle a NULL return value from find_pipeline
+	- return immediately from delete_job if jobs[index] is already NULL or

+parse.y
+	- when calling parse_matched_pair on a $(...) command substitution,

+	  and fix from Mike Stroyan <mike.stroyan@hp.com>
+
+jobs.c
+	- start maintaining true count of living children in js.c_living
+	- call reset_current in realloc_jobs_list, since old values for current
+	  and previous job are most likely incorrect
+	- don't allocate a new list in realloc_jobs_list if the old size and
+	  new size are the same; just compact the existing list
+	- make sure realloc_jobs_list updates value of js.j_njobs
+	- add some more itrace messages about non-null jobs after j_lastj in

+
+				   1/13
+				   ----
+lib/readline/vi_mode.c
+	- move code that moves forward a character out of rl_vi_append_mode
+	  into a separate function, _rl_vi_append_forward
+	- change _rl_vi_append_mode to save `a' as the last command, so it
+	  can be redone properly
+	- new function _rl_vi_backup, moves point back a character taking
+	  multibyte locales into account
+	- change rl_vi_redo to handle redoing an `a' command specially --
+	  it should be redone like `i' but after moving forward a character
+	- change rl_vi_redo to use _rl_vi_backup to move point backward
+	  after redoing `i' or `a'
+
+jobs.c
+	- new function, delete_old_job (pid), checks whether or not PID is in
+	  a job in the jobs list.  If so, and the job is dead, it just removes
+	  the job from the list.  If so, and the job is not dead, it zeros
+	  the pid in the appropriate PROCESS so pid aliasing doesn't occur
+	- make_child calls delete_old_job to potentially remove an already-used
+	  instance of the pid just forked from the jobs list if pids have
+	  wrapped around.  Finally fixes the bug reported by Tim Waugh
+	  <twaugh@redhat.com>
+
+trap.c
+	- new define, GETORIGSIG(sig), gets the original handling for SIG and
+	  sets SIG_HARD_IGNORE if that handler is SIG_IGN
+	- call GETORIGSIG from initialize_traps, get_original_signal, and
+	  set_signal
+
+jobs.c
+	- in wait_for, if the original SIGINT handler is SIG_IGN, don't set
+	  the handler to wait_sigint_handler.  This keeps scripts started in
+	  the background (and ignoring SIGINT) from dying due to SIGINT while
+	  they're waiting for a child to exit.  Bug reported by Ingemar
+	  Nilsson <init@kth.se>
+
+lib/readline/vi_mode.c
+	- don't save text to buffer unless undo pointer points to a record of

+	  Craig Turner <craig@synect.com> with redoing `ctd[ESC]' (empty
+	  insert after change to)
+
+shell.c
+	- change set_shell_name so invocations like "-/bin/bash" are marked as
+	  login shells
+
+doc/bash.1
+	- add note about destroying functions with `unset -f' to the section
+	  on shell functions
+
+lib/readline/terminal.c
+	- if readline hasn't been initialized (_rl_term_autowrap == -1, the
+	  value it's now initialized with), call _rl_init_terminal_io from
+	  _rl_set_screen_size before deciding whether or not to decrement
+	  _rl_screenwidth.  Fixes bug from Mike Frysinger <vapier@gentoo.org>

+
+lib/readline/doc/rltech.texi
+	- documented valid values for timeout in rl_set_keyboard_input_timeout
+
+jobs.c
+	- in stop_pipeline, don't have the parent shell call give_terminal_to
+	  if subshell_environment contains SUBSHELL_ASYNC (no background

+lib/readline/display.c

+	  is before the last invisible character in the prompt string to
+	  differentiate between the multibyte character case (where
+	  _rl_last_c_pos is a physical cursor position) and the single-byte

+sig.h,{jobs,nojobs,sig,trap}.c,builtins/trap.def
+	- rename termination_unwind_protect to termsig_sighandler
+
+sig.c
+	- split termsig_sighandler into two functions: termsig_sighandler, which
+	  runs as a signal handler and sets a flag noting that a terminating
+	  signal was received, and termsig_handler, which runs when it is `safe'
+	  to handle the signal and exit
+	- new terminate_immediately variable, similar to interrupt_immediately
+	- termsig_sighandler calls termsig_handler immediately if
+	  terminate_immediately is non-zero
+
+quit.h
+	- change CHECK_TERMSIG macro to check terminating_signal and call
+	  termsig_handler if it's non-zero
+	- add same check of terminating_signal and call to termsig_handler to

+
+{jobs,nojobs}.c

+
+lib/readline/readline.h

+
+subst.h
+	- extern declaration for fifos_pending()
+
+execute_cmd.c
+	- in execute_simple_command, if CMD_NO_FORK is set before we call
+	  execute_disk_command, make sure there are no FIFOs in the expanded

+
+lib/readline/histfile.c

+	  character at the beginning of a line is a digit before interpreting
+	  it as a timestamp for the previous line
+
+doc/{bash.1,bashref.texi},lib/readline/doc/hsuser.texi

+array.c
+	- new function, array_quote_escapes (ARRAY *a), calls quote_escapes

+	  quote_string
+	- call array_quote_escapes if match is not quoted in array_patsub
+	- array_slice is now used, so remove the #ifdef INCLUDE_UNUSED define
+	- change structure of array_subrange to call array_slice to create a
+	  new array with the desired subset of elements, then call array_quote
+	  or array_quote_escapes as necessary, like array_patsub.  Convert to
+	  a string by calling array_to_string on the sliced-out array
+
+array.h
+	- new extern declaration for array_quote_escapes
+
+subst.c
+	- since array_patsub now calls quote_escapes as necessary, callers

+
+builtins/common.c

+
+execute_cmd.c
+	- change execute_cond_node to pass 2 (regexp match), 1 (shell pattern

+
+subst.c
+	- change cond_expand_word to translate SPECIAL==2 into passing
+	  QGLOB_REGEXP to quote_string_for_globbing
+
+locale.c
+	- by default, if all else fails, set shell's idea of locale to ""

+
+builtins/common.c

+	  in a builtin command context (no_args(), get_numeric_arg()).  Fixes
+	  bug reported by Ian Watson
+
+lib/readline/display.c
+	- in _rl_move_cursor_relative, use `new' when comparing against

+
+include/typemax.h

+
+lib/readline/display.c
+	- in rl_redisplay() and update_line(), if redrawing the prompt because
+	  it contains invisible characters, make sure we redraw the character
+	  indicating a modified history line and take it into account when
+	  computing _rl_last_c_pos

+	- change read_comsub to do the same thing for unquoted command

+support/shobj-conf
+	- add host_vendor to string tested in switch to handle things like
+	  gentoo/freebsd
+	- beginning with version 7, FreeBSD no longer has /usr/bin/objformat
+	  or a.out binaries and libraries.  It's always ELF.  Fix from
+	  Timothy Redaelli <drizzt@gentoo.org>
+
+parse.y
+	- in parse_comsub, allow comments if we are ready to read a
+	  reserved word (tflags & LEX_RESWDOK), haven't read anything from
+	  one yet (lex_rwlen == 0) and the current character is a '#'
+
+				    3/6
+				    ---
+parse.y
+	- new lex flag for parse_comsub: LEX_INWORD.  Turn it off when
+	  we see a shell break character; turn it on or keep it on when
+	  not a break character.  Keep track of word length (reset to 0
+	  when we turn on LEX_INWORD when it was off).
+	- don't use COMMENT_BEGIN in parse_comsub any more; test
+	  whether or not LEX_INWORD is set and lex_wlen == 0 in addition
+	  to tests for LEX_RESWDOK and lex_rwlen.  Comments are valid
+	  when at the start of a word
+	- move LEX_PASSNEXT code to the top of parse_comsub, so the rest
+	  of the function doesn't have to check for the flag at different
+	  places
+
+				    3/7
+				    ---
+parse.y
+	- in parse_comsub, when looking for a reserved word (LEX_RESWDOK
+	  non-zero), and in a case statement, we can see either an esac
+	  or a pattern list.  We handle an esac separately.  We should
+	  turn off LEX_RESWDOK if we see anything but a newline, since
+	  we'll be reading a pattern list.  Other part of fix for bug

+	  fix from Clark Jian Wang <dearvoid@gmail.com>
+
+parse.y
+	- make parser_state global, so other files can use it
+	- command_word_acceptable now returns non-zero if PST_REDIRLIST bit
+	  set in parser_state, so we accept assignment statements and
+	  perform alias expansion.  Fix for bug reported by Vincent
+	  Lefevre <vincent@vinc17.org> (2/24/2009)
+
+parser.h
+	- add PST_REDIRLIST flag, notes that parser is currently parsing a
+	  redirection list preceding a simple command
+
+make_cmd.c
+	- make_simple_command now turns on PST_REDIRLIST in parser_state when
+	  creating a new simple command
+	- make_simple_command turns off PST_REDIRLIST in parser_state if it
+	  adds a non-redirection to the command it's building
+	- clean_simple_command turns off PST_REDIRLIST to make sure it's off
+
+subst.c
+	- new flag for param_expand: PF_IGNUNBOUND, means to not exit if the
+	  variable is unbound even if `set -u' is enabled
+	- change param_expand to not call err_unboundvar if the `pflags'
+	  argument has the PF_IGNUNBOUND bit set
+	- parameter_brace_expand_word now takes an extra `pflags' argument to
+	  pass down to param_expand; changed callers
+	- changed call to parameter_brace_expand_word in parameter_brace_expand
+	  to add PF_IGNUNBOUND flag so ${@:-foo} doesn't cause the shell to
+	  exit (but ${@} does) when there are no positional parameters.  Fixes	
+	  Debian bug 519165 from Dan Jacobson <jidanni@jidanni.org>

+	  when IFS= and args are `a b' as noted by Stephane Chazleas
+	  <stephane_chazelas@yahoo.fr>
+	- param_expand now checks for Q_PATQUOTE and treats it identically
+	  to Q_DOUBLE_QUOTES when expanding $*
+	- expand_word_unsplit now sets W_NOSPLIT in the flags of the word it
+	  passes to expand_word_internal if $IFS is NULL
+	- expand_word_leave_quoted now sets expand_no_split_dollar_star and
+	  the W_NOSPLIT bit in the word flags before calling
+	  expand_word_internal if $IFS is NULL, just like expand_word_unsplit.
+	  It is now virtually identical to expand_word_unsplit.  Rest of fix for

+builtins/fc.def
+	- Even though command substitution through parse_and_execute turns

+bashline.c
+	- in bash_dequote_filename, return right away after copying the

+subst.c
+	- in pat_subst.c, make sure to copy one character from the input

+lib/readline/display.c
+	- modify change of 7/24 to use prompt_physical_chars instead of
+	  prompt_visible_length to account for visible multibyte characters in
+	  the line (usually in the prompt).  Fixes debian bug #547264
+	  reported by Pietro Battiston <toobaz@email.it>
+	- add flags argument to _rl_col_width; changed callers.  flags > 0
+	  means that it's ok to use the already-computed prompt information;
+	  flags == 0 means that we're expanding the prompt and we should not
+	  short-circuit
+
+parse.y
+	- in decode_prompt_string, when expanding \w and \W on Mac OS X,
+	  use fnx_fromfs to convert from "filesystem" form to "input" form.
+	  This makes $PWD with multibyte characters work in the prompt
+	  string on Mac OS X
+
+lib/sh/fnxform.c
+	- in fnx_fromfs and fnx_tofs, use templen instead of outlen as last
+	  argument in calls to iconv, since outlen is used to keep track of
+	  the size of the buffer, and iconv potentially modifies its
+	  `outbytesleft' argument

+
+subst.c
+	- implement semantics of SD_NOSKIPCMD in skip_to_delim
+
+bashline.c
+	- call skip_to_delim with SD_NOSKIPCMD from find_cmd_start, so

+	- move assign_vars label before decrement of interrupt_immediately and
+	  terminate_immediately so those variables get reset appropriately
+	  if read -t times out

+
+subst.c
+	- in parameter_brace_expand, before calling parameter_brace_expand_rhs,

+
+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}

+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

+	  not available
+	- look for mbsnrtowcs and define HAVE_MBSNRTOWCS if available
+
+lib/sh/xmbsrtowcs.c

+	- 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

+	  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

+parse.y,bashline.c,externs.h
+	- history_delimiting_chars now takes a const char * as an argument:

+
+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

+		copy_fifo_list - returns a bitmap of open FDs or active FIFOs
+		  by index into appropriate list (dev_fd_list or fifo_list)

+		  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

+
+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

+
+doc/bashref.texi
+	- add note to the posix mode section of the texinfo manual noting

+
+parse.y

+
+/* DYNAMIC VARIABLES
+
+   These are variables whose values are generated anew each time they are
+   referenced.  These are implemented using a pair of function pointers
+   in the struct variable: assign_func, which is called from bind_variable
+   and, if arrays are compiled into the shell, some of the functions in
+   arrayfunc.c, and dynamic_value, which is called from find_variable.
+
+   assign_func is called from bind_variable_internal, if
+   bind_variable_internal discovers that the variable being assigned to
+   has such a function.  The function is called as
+	SHELL_VAR *temp = (*(entry->assign_func)) (entry, value, ind)
+   and the (SHELL_VAR *)temp is returned as the value of bind_variable.  It
+   is usually ENTRY (self).  IND is an index for an array variable, and
+   unused otherwise.
+
+   dynamic_value is called from find_variable_internal to return a `new'
+   value for the specified dynamic varible.  If this function is NULL,
+   the variable is treated as a `normal' shell variable.  If it is not,
+   however, then this function is called like this:
+	tempvar = (*(var->dynamic_value)) (var);
+
+   Sometimes `tempvar' will replace the value of `var'.  Other times, the
+   shell will simply use the string value.  Pretty object-oriented, huh?
+
+   Be warned, though: if you `unset' a special variable, it loses its
+   special meaning, even if you subsequently set it.
+
+   The special assignment code would probably have been better put in
+   subst.c: do_assignment_internal, in the same style as
+   stupidly_hack_special_variables, but I wanted the changes as
+   localized as possible.  */
