+array.c
+ - in array_insert(), make sure the value to be added is non-NULL before
+ calling savestring() on it
+
+builtins/reserved.def
+ - fix description of `CDPATH'
+
+lib/readline/display.c
+ - when expanding a prompt that spans multiple lines with embedded
+ newlines, set prompt_physical_chars from the portion after the
+ final newline, not the preceding portion. Bug reported by
+ "Ralf S. Engelschall" <rse@engelschall.com>
+
+make_cmd.c
+ - explicitly declare `lineno' in function prologue for make_case_command
+
+builtins/evalfile.c
+ - include `trap.h' for declaration for run_return_trap
+
+bashline.c
+ - fix a `return' without a value in enable_hostname_completion

+tests/{history,histexp}.tests
+ - unset HISTFILESIZE to avoid problems if a value of 0 is inherited
+ from the environment
+
+ 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
+ - call MB_STRLEN instead of STRLEN where appropriate in
+ 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

+ - 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

+ - 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

+
+ 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 *
+

+[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
+

+ ----
+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,

+
+ 9/18

+lib/sh/shquote.c
+ - don't quote CTLESC and CTLNUL with CTLESC in sh_backslash_quote, as

+ 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

+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

+command.h
+ - add a `W_NOEXPAND' flag to inhibit all expansion except quote removal

+
+subst.c
+ - pass W_NOXPAND and W_COMPASSIGN through end of expand_word_internal

+ - 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

+ statement given as argument to assignment builtin
+

+ - 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

+ - 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

+ 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 --

+
+execute_cmd.c
+ - change execute_builtin so that if CMD_COMMAND_BUILTIN is set in the

+
+support/mksignames.c

+ 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

+ wrapped around. Finally fixes the bug reported by Tim Waugh

+ 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

+ Primarily intended for use on MacOS X, they use iconv to convert
+ between whatever the current locale encoding is and "UTF-8-MAC",
+ a special encoding on OS X in which all characters are
+ decomposed unicode, as the HFS+ filesystem stores them. These
+ functions return a pointer to a local buffer, allocated once and
+ resized as necessary, to avoid too many allocations; callers
+ should not free the return value, since it may be the string
+ passed
+
+Makefile.in
+ - make sure LIBICONV is set by autoconf (@LIBICONV@) and added to
+ list of link libraries
+
+externs.h
+ - new extern declarations for fnx_fromfs and fnx_tofs
+
+lib/glob/glob.c
+ - convert the filename read using readdir() in glob_vector() using
+ fnx_fromfs and use that value in the call to strmatch. This
+ ensures that we're using the precomposed Unicode value of the
+ filename rather than the native decomposed form. Original bug
