+[bash-3.1 released]
+
+				   12/9
+				   ----
+doc/{bash.1,version.texi},lib/readline/doc/version.texi
+	- remove `beta1' from man page footer and texinfo documents
+
+variables.c
+	- make sure winsize_assignment is protected by #ifdef READLINE, so
+	  minimal shell will compile
+
+builtins/read.def
+	- make sure error cases free memory and run any unwind-protects to
+	  avoid memory leaks
+
+				   12/10
+				   -----
+execute_cmd.c
+	- change execute_command_internal to set $PIPESTATUS for ((...)) and
+	  [[ ... ]] commands
+
+doc/{bash.1,bashref.texi,version.texi}
+	- add documentation for ulimit -[iqx] and bump revision date
+
+				   12/12
+				   -----
+parse.y
+	- make sure parse_compound_assignment saves and restores the
+	  PST_ASSIGNOK parser state flag around its calls to read_token.
+	  Fixes bug reported by Mike Frysinger
+
+				   12/13
+				   -----
+parse.y
+	- change parse_compound_assignment to save and restore the value of
+	  last_read_token.  Not sure why it was set unconditionally in the
+	  first place after parsing the complete compound assignment
+
+				   12/14
+				   -----
+lib/readline/text.c
+	- don't use return value of rl_kill_text (which always succeeds and
+	  returns the number of characters killed) in rl_delete as an indication
+	  of success or failure
+	- 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
+	  callers (return 0 all the time to indicate that a readline function
+	  was found and dispatched).  Fix from Andreas Schwab for <DEL><DEL>
+	  bug in callback interface first reported by Mike Frysinger
+
+execute_cmd.c
+	- fixed a typo in execute_case_command
+
+				   12/15
+				   -----
+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
+	  should catch the deficient NetBSD multibyte support
+
+				   12/16
+				   -----
+parse.y
+	- use CTLESC instead of literal '\001' when decode_prompt_string
+	  prefixes RL_PROMPT_START_IGNORE and RL_PROMPT_END_IGNORE
+
+				   12/20
+				   -----
+lib/readline/display.c
+	- don't treat RL_PROMPT_START_IGNORE specially inside a sequence of
+	  ignored characters
+	- keep track of the start of the current sequence of ignored
+	  characters; make sure that an empty sequence of such characters
+	  really is an empty sequence, not one that happens to end with '\001'
+	  (RL_PROMPT_START_IGNORE)
+
+				   12/21
+				   -----
+subst.c
+	- change expand_word_internal to process rest of `tilde-word' as a
+	  regular part of the word if tilde expansion leaves the tilde-word
+	  unchanged.  This means that ~$USER expands to ~chet, which seems
+	  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
+	  sure that we don't use a variable of the same name from a previous
+	  context
+
+doc/bash.1
+	- documented expansions for word and patterns in case statement
+
+builtins/ulimit.def,doc/{bashref.texi,bash.1}
+	- added new -e and -r (nice and rtprio) options to ulimit; documented
+	  them
+
+				   12/26
+				   -----
+variables.c
+	- use `hmax' instead of `num' in sv_histsize to avoid integer overflow
+	  problems with intmax_t
+
+builtins/read.def
+	- add unwind-protect to restore rl_attempted_completion_function in
+	  case of a timeout
+
+{bashline,variables}.c
+	- move initialization of HISTSIZE from initialization path to
+	  load_history, so it can be overridden by a value assigned in a
+	  startup file
+
+lib/readline/misc.c
+	- add a missing `return r' so that rl_digit_loop returns a meaningful
+	  value
+
+lib/readline/{bind,callback,display,isearch,rltty,search,text,vi_mode}.c
+	- minor cleanups to satisfy compiler warnings, mostly removing unused
+	  variables
+
+				   12/27
+				   -----
+support/Makefile.in
+	- add LIBS_FOR_BUILD support; defaults to ${LIBS}
+
+Makefile.in
+	- add LIBS_FOR_BUILD with no default value; use when linking programs
+	  using CC_FOR_BUILD (e.g., bashversion)
+
+				   12/28
+				   -----
+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
+	  entire thing to evalexp()
+
+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
+	  semantics
+
+tests/new-exp.tests
+	- change tests to remove all ${pat//#rep} and ${pat//%rep}
+	  expansions, since they don't mean the same thing anymore
+
+				   12/29
+				   -----
+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
+				   -----
+command.h
+	- new word flag: W_NOPROCSUB, inhibits process substitution on a word
+
+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
+	  if it has a null pipeline associated with it
+	- in delete_job, if find_last_proc returns NULL, don't try to call
+	  bgp_delete
+
+				    1/7
+				    ---
+doc/bash.1
+	- patch from Tim Waugh to replace some literal single quotes with
+	  \(aq, the groff special character for it
+
+jobs.c
+	- in realloc_jobs_list, make sure to zero out slots after j_lastj
+	  in the new list
+
+				    1/9
+				    ---
+support/mksignames.c
+	- make sure to include <signal.h> to get right value of NSIG from
+	  (usually) <sys/signal.h>
+
+				   1/10
+				   ----
+parse.y
+	- when calling parse_matched_pair on a $(...) command substitution,
+	  don't pass the P_DQUOTE flag so that single quotes don't get
+	  stripped from $'...' inside the command substitution.  Bug report
+	  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
+	  jobs array
+
+				   1/11
+				   ----
+bashjmp.h
+	- new value for second argument to longjmp: SIGEXIT.  Reserved for
+	  future use
+
+				   1/12
+				   ----
+jobs.c
+	- add logic to make_child to figure out when pids wrap around
+	- turn second argument to delete_job into flags word, added flag to
+	  prevent adding proc to bgpids list
+
+				   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
+	  type UNDO_INSERT; zero it out instead.  This fixes bug reported by
+	  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>
+
+				   1/14
+				   ----
+lib/readline/input.c
+	- allow rl_set_keyboard_input_timeout to set the timeout to 0, for
+	  applications that want to use select() like a poll without any
+	  waiting
+
+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
+	  process should ever give the terminal to anything other than
+	  shell_pgrp)
+	- in make_child, don't give the terminal away if subshell_environment
+	  contains SUBSHELL_ASYNC
+
+				   1/15
+				   ----
+subst.c
+	- in parameter_brace_expand, if extracting ${#varname}, only allow
+	  `}' to end the expansion, since none of the other expansions are
+	  valid.  Fixes Debian bug reported by Jan Nordhorlz <jckn@gmx.net>
+
+				   1/17
+				   ----
+parse.y
+	- in parse_matched_pair, protect all character tests with the MBTEST
+	  macro
+	- in parse_dparen, take out extra make_word after call to alloc_word_desc
+	  (mem leak)
+
+				   1/18
+				   ----
+parse.y
+	- in parse_matched_pair, add P_ALLOWESC to flags passed to recursive
+	  parse_matched_pair call when encountering a single or double quote
+	  inside a ``-style command substitution
+
+execute_cmd.c
+	- add call to QUIT at beginning of execute_command_internal; better
+	  responsiveness to SIGINT
+
+				   1/21
+				   ----
+lib/readline/bind.c
+	- change rl_invoking_keyseqs_in_map to honor the setting of
+	  convert-meta when listing key bindings, since if convert-meta is off,
+	  using '\M-' as the prefix for bindings in, for instance,
+	  emacs-escape-keymap, is wrong.  This affects `bind -p' output
+	- change rl_untranslate_keyseq to add '\e' instead of '\C-[' for
+	  ESC
+
+execute_cmd.c
+	- add call to QUIT at end of execute_command
+
+				   1/23
+				   ----
+lib/readline/display.c
+	- changed two places in update_line where a check of whether the cursor
+	  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
+	  case (where it is a buffer index).  This prevents many unnecessary
+	  \r-redraw the line sequences.  Reported by Dan Jacobson.
+
+				   1/24
+				   ----
+quit.h
+	- wrap QUIT macro in do...while(0) like other compound statement
+	  macros
+	- CHECK_TERMSIG define (placeholder for now); future use will be to
+	  handle any received signals that should  cause the shell to
+	  terminate (e.g., SIGHUP)
+
+{input,jobs,nojobs}.c
+	- add calls to CHECK_TERMSIG where appropriate (reading input and
+	  waiting for children)
+	- include quit.h if necessary
+
+				   1/25
+				   ----
+parse.y
+	- undo change that makes `)' in a compound assignment delimit a token.
+	  It messes up arithmetic expressions in assignments to `let', among
+	  other things
+
+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
+	  QUIT macro
+
+{jobs,nojobs}.c
+	- change call to termsig_sighandler to call termsig_handler directly,
+	  as was intended
+
+parse.y,builtins/read.def
+	- set terminate_immediately to non-zero value when reading interactive
+	  input, as is done with interrupt_immediately
+
+				   1/26
+				   ----
+doc/{bash.1,bashref.texi}
+	- reworded the POSIX standard references to remove mention of POSIX.2
+	  or 1003.2 -- it's all the 1003.1 standard now.  Recommended by
+	  Arnold Robbins
+
+				   1/27
+				   ----
+lib/readline/complete.c
+	- move call to filename dequoting function into
+	  rl_filename_completion_function; call only if directory completion
+	  hook isn't set.  This means that directory-completion-hook now needs
+	  to dequote the directory name.  We don't want to dequote the directory
+	  name before calling the directory-completion-hook.  Bug reported by
+	  Andrew Parker <andrewparker@bigfoot.com>
+
+bashline.c
+	- add necessary directory name dequoting to bash_directory_completion_hook
+	  and bash_directory_expansion
+
+lib/readline/doc/rltech.texi
+	- add note to description of rl_directory_completion_hook that it
+	  needs to dequote the directory name even if no other expansions are
+	  performed
+
+				   1/28
+				   ----
+braces.c
+	- make sure that we skip over braces that don't start a valid matched
+	  brace expansion construct in brace_expand -- there might be a valid
+	  brace expansion after the unmatched `{' later in the string
+	- brace_gobbler now checks that when looking for a `}' to end a brace
+	  expansion word, there is an unquoted `,' or `..' that's not inside
+	  another pair of braces.  Fixes the a{b{c,d}e}f problem reported by
+	  Tim Waugh
+
+builtins/declare.def
+	- when not in posix mode, and operating on shell functions, typeset
+	  and declare do not require their variable operands to be valid
+	  shell identifiers.  The other `attribute' builtins work this way.
+	  Fixes inconsistency reported by Mike Frysinger
+
+{configure,config.h}.in
+	- add test for setregid, define HAVE_SETREGID and HAVE_DECL_SETREGID
+	  as appropriate
+	- add test for eaccess, define HAVE_EACCESS if found
+
+lib/sh/eaccess.c
+	- new file, with sh_stat and sh_eaccess functions, moved from test.c
+	- renamed old sh_eaccess as sh_stataccess, since it uses the stat(2)
+	  information to determine file accessibility
+	- new function, sh_euidaccess, to call when uid != euid or gid != egid;
+	  temporarily swaps uid/euid and gid/egid around call to access
+	- rewrote sh_eaccess to call eaccess, access, sh_euidaccess or
+	  sh_stataccess as appropriate.  access(2) will take into account
+	  things like ACLs, read-only file systems, file flags, and so on.
+
+lib/sh/Makefile.in,Makefile.in
+	- add necessary entries for eaccess.[co]
+
+test.c
+	- change calls to test_stat to call sh_stat
+
+{test,general}.c
+	- change calls to test_eaccess to call sh_eaccess
+
+externs.h
+	- new extern declaration for sh_eaccess
+
+test.[ch]
+	- remove test_stat and test_eaccess
+
+				   1/29
+				   ----
+braces.c
+	- make change from 1/28 dependant on CSH_BRACE_COMPAT not being
+	  defined (since old bash behavior is what csh does, defining
+	  CSH_BRACE_COMPAT will produce old bash behavior)
+
+				   1/30
+				   ----
+bashline.c
+	- last argument of bash_default_completion is now a flags word:
+	  DEFCOMP_CMDPOS (in command position) is only current value
+	- attempt_shell_completion now computes flags before calling
+	  bash_default_completion
+	- if no_empty_command_completion is set, bash does not attempt command
+	  word completion even if not at the beginning of the line, as long
+	  as the word to be completed is empty and start == end (catches
+	  beginning of line and all whitespace preceding point)
+
+				    2/4
+				    ---
+lib/readline/display.c
+	- change _rl_make_prompt_for_search to use rl_prompt and append the
+	  search character to it, so the call to expand_prompt in rl_message
+	  will process the non-printing characters correctly.  Bug reported
+	  by Mike Stroyan <mike.stroyan@hp.com>
+
+				    2/5
+				    ---
+lib/readline/display.c
+	- fix off-by-one error when comparing against PROMPT_ENDING_INDEX,
+	  which caused a prompt with invisible characters to be redrawn one
+	  extra time in a multibyte locale.  Change from <= to < fixes
+	  multibyte locale, but I added 1 to single-byte definition of
+	  PROMPT_ENDING_INDEX (worth checking) to compensate.  Bug reported
+	  by Egmont Koblinger <egmont@uhulinux.hu>
+
+				    2/8
+				    ---
+lib/readline/terminal.c
+	- call _emx_get_screensize with wr, wc like ioctl code for consistency
+	- new function, _win_get_screensize, gets screen dimensions using
+	  standard Windows API for mingw32 (code from Denis Pilat)
+	- call _win_get_screensize from _rl_get_screen_size on mingw32
+
+lib/readline/rlconf.h
+	- define SYS_INPUTRC (/etc/inputrc) as system-wide default inputrc
+	  filename
+
+support/shobj-conf
+	- changes to make loadable builtins work on MacOS X 10.[34]
+
+builtins/pushd.def
+	- changes to make it work as a loadable builtin compiled with gcc4
+
+				    2/9
+				    ---
+lib/readline/bind.c
+	- add SYS_INPUTRC as last-ditch default (if DEFAULT_INPUTRC does not
+	  exist or can't be read) in rl_read_init_file
+
+lib/readline/doc/rluser.texi
+	- add description of /etc/inputrc as ultimate default startup file
+
+				   2/10
+				   ----
+lib/readline/bind.c
+	- fix problem with rl_function_of_keyseq that returns a non-keymap
+	  bound to a portion of the passed key sequence without processing
+	  the entire thing.  We can bind maps with existing non-map
+	  functions using the ANYOTHERKEY binding code.
+
+variables.c
+	- shells running in posix mode do not set $HOME, as POSIX apparently
+	  requires
+
+				   2/15
+				   ----
+braces.c
+	- mkseq() now takes the increment as an argument; changed callers
+
+				   2/16
+				   ----
+builtins/hash.def
+	- print `hash table empty' message to stdout instead of stderr
+
+				   2/17
+				   ----
+lib/readline/readline.c
+	- when resetting rl_prompt in rl_set_prompt, make sure rl_display_prompt
+	  is set when the function returns
+
+				   2/18
+				   ----
+lib/readline/display.c
+	- further fixes to _rl_make_prompt_for_search from Eric Blake to deal
+	  with multiple calls to expand_prompt
+
+				   2/21
+				   ----
+builtins/hash.def
+	- don't print `hash table empty' message in posix mode
+
+				   2/27
+				   ----
+lib/glob/sm_loop.c
+	- change extmatch() to turn off FNM_PERIOD in flags passed to recursive
