This version of dialog was originally from a Debian snapshot.  I've done this
to it:

2003/12/07
	+ correct infinite loop in yesno widget when "--defaultno" option is
	  combined with "--no-cancel" (Debian #223077).

2003/11/30
	+ suppress double-quotes added for "--help-status" option if the
	  string does not contain any special characters.

2003/11/26
	+ add samples/sourcemage.rc, for comparison with slackware.rc
	+ add "--insecure" option (request by Sean Mathews [e-mail]).
	+ make "--defaultno" option apply to widgets which use OK/Cancel
	  buttons as well (Debian #209030).
	+ improve documentation of exit-codes for each widget in the manpage
	  (Debian #217926).
	+ add option "--keep-window" to suppress repainting after completing
	  each widget (request by Ingo van Lil <[e-mail]>).
	+ add options "--yes-label" and "--no-label" to allow override of the
	  "Yes" and "No" strings (request by Christoph Zwerschke
	  <[e-mail]>).
	+ add option "--help-status" to allow script to restore a checklist
	  or radiolist after processing an item-help string (Debian #209031).
	+ modify width-calculation for non-formatted text to ensure it is
	  wide enough for the longest word in the text (patch by Andrew Gaul
	  <[e-mail]>).
	+ modify dlg_index_columns() to count a newline as a single cell rather
	  than 2 for the normal curses case.  This fixes an off-by-one for
	  the text-justification, shown in screen 2 of msgbox1 sample script.
	+ fix dlg_char_to_button(); 2003/09/10 changes made it incorrectly
	  ignore case of the labels.
	+ change calendar's use of arrow keys so they are (as before 2002/6/22)
	  interpreted within the day-grid as movement within that grid (request
	  by David Anders <[e-mail]>).
	+ correct missing initialization of last_getc variable in dlg_getc()
	  (report/analysis by Victor Wodecki).
	+ modify main program to make
		dialog --no-shadow --print-maxsize
	  work.  Normally dialog prints the screen size after subtracting the
	  area reserved for shadows, but some applications may need the actual
	  screen size (Debian #213424).
	+ several related changes (Debian #213425):
	  + separate the examples using "--stdout" and "--output-fd" from the
	    normal usage examples.
	  + add "--input-fd" option, provide a sample of its use.
	  + modify init_dialog() to use initscr() unless a "--stdout" option
	    was used.  Some scripts relied on the coincidence that redirecting
	    standard output from dialog would "work".  Before this change
	    init_dialog() assumed that redirected standard output was
	    synonymous with "--stdout" option (not the intended behavior).
	  + modify command-line parsing to look for "--stdout" and "--stderr"
	    options first, allowing only one.
	  + add a check for an environment variable $DIALOG_TTY which provides
	    the older behavior, i.e., try to open the terminal directly if
	    stdout is redirected.
	+ interface changes, to make libdialog simpler to use:
	  + rename all of the internal functions to begin with "dlg_", but
	    provide compatibility with older names if the application defines
	    __DIALOG_OLD_NAMES__.
	  + add dialog_version() function, and corresponding DIALOG_VERSION and
	    DIALOG_PATCHDATE definitions to dlg_config.h
	  + eliminate remaining global variables such as screen_initialized in
	    favor of dialog_state and dialog_vars.
	  + move some data such as dialog_vars.output to dialog_state, since
	    they are normally not reset between widgets.
	  + change interfaces of dialog_yesno() and dialog_checklist() to use
	    dialog_state.defaultno and dialog_vars.separate_output, making it
	    simpler and more consistent.
	+ improve configure script and related definitions:
	  + add "--with-libtool" option to provide shared library support by
	    libtool.
	  + rename generated "config.h" to "dlg_config.h", so it can be
	    installed without naming conflict.  Added "dlg_config.h" to
	    install-lib rule.
	  + modify configure script and makefile to use EXEEXT and OBJEXT.
	  + add "--enable-widec" option to control whether wide-curses features
	    are compiled-in, rather than check for the existence of those in
	    the curses library.  This allows building with HPUX curses, which
	    has abandoned legacy features while not quite supporting X/Open
	    curses.
	  + add configure check for getbegx(), etc., which are not provided on
	    all platforms.
	+ update config.guess, config.sub

2003/10/02
	+ update hu.po (Arpad Biro).
	+ revert part of the 2003/08/18 change to "--stdout" option.  Using
	  stderr for screen output does not work well on several platforms
	  since stdout's settings are affected (report by Kent Robotti).

2003/09/24
	+ modify tailbox to allow it to display files with arbitrarily long
	  lines.
	+ fix an infinite loop in tailbox, broken when making interface changes
	  to dlg_getc() (report by Ingo van Lil).
	+ amend fix for "--and-widget" to not treat "---" as an option (report
	  by Kent Robotti).
	+ updated es.po (Santiago Vila).

2003/09/10
	+ correct "RENAMED" result from inputmenu widget, which did not reset
	  the result buffer, and did not account for scroll-offset (Debian
	  #209336).
	+ modify button, menu and checkbox logic that matches a character to
	  the beginning of a text field to support wide-characters (completes
	  Debian #195674).
	+ modify configure script to not use "head -1".

2003/08/30
	+ modify searchbox popup in textbox widget so one can simply press
	  return on an empty input to cancel the popup.
	+ modify error reporting to avoid clearing screen if a problem is
	  found in the ".rc" file.
	+ add color/attribute combinations for form widget (based on patch by
	  Reznic Valery).
	+ combine rc-file colors, attribute- and color-tables to obtain a
	  single table for color values, which requires less work to add new
	  entries.
	+ modify fselect widget to make back-tab work again, since it was
	  broken by the rewrite of dlg_edit_string().
	+ modify howmany_tags() so it will quit searching when it finds any
	  option, not only "--and-widget" (Debian #206636).
	+ correct call to dlg_print_text() in print_line(), which did not
	  account for hidden characters (report/patch by David Poole
	  <[e-mail]>).
	+ modify print_button() to display properly if locale defines ok/cancel
	  or yes/no buttons that contain multibyte characters.

2003/08/20
	+ correct an indexing error when deleting from the end of a line using
	  KEY_DC; it happened to work on Linux because malloc() clears memory
	  like calloc().
	+ add '\r' to case statement where '\n' is translated to KEY_ENTER to
	  work around defect in NetBSD curses.
	+ modify configure check for getparyx(), etc., which are implemented
	  by NetBSD curses as functions rather than macros.
	+ correct configure check for term.h, which may be <ncursesw/term.h>
	  if ncursesw development headers are installed, but not ncurses
	  development headers.  Or they may not coincide (Debian #206287).

2003/08/18
	+ modify checkbox.c and menubox.c to display tags properly if they
	  contain wide-characters.
	+ better solution for initializing curses when "--stdout" option is
	  used, e.g., use stderr for the output if it is a tty.  Also correct
	  the error handling, so dialog exits with an error if it cannot
	  find a way to do output (Debian #205509).
	+ modify sample scripts to use consistent definition of $DIALOG
	  (Debian #205508).
	+ add UTF-8 examples msgbox4-utf8, inputbox6-utf8 (from Tomohiro KUBOTA
	  as testcases for Debian #195674).
	+ modify print_line() to work with wide-characters, e.g., so it handles
	  wrapping for double-width characters.
	+ cache results from multibyte character indices, speeds up cursor
	  movement.
	+ modify form widget to support scrolling and mouse-selection.
	+ add form widget (based on patch by Reznic Valery).
	+ correct mouse-handling for inputmenu widget.
	+ corrections to menu.c: location of clearing operation, and height of
	  rows in code for older ncurses versions (patch by Reznic Valery
	  <[e-mail]>).
	+ improve logic that compensates for xterm's alternate-screen by
	  cancelling the rmcup/smcup strings after the rmcup has been issued.
	  That ensures that dialog will not clear the screen on exit (report
	  by Javier Kohen).
	+ modify initialization between widgets to retain the values for the
	  --aspect, --separate-widget and --tab-len options.
	+ add --separator as an alias for --separate-widget (Xdialog).
	+ correct handling of Xdialog's --icon and --wmclass options, whose
	  parameter was not ignored.
	+ correct logic for --separate-widget so its string is written before
	  each output, rather than only for --and-widget option (report by
	  Javier Kohen <[e-mail]>).
	+ improve limit-check in center_label() for buttons.c (report by Tor
	  Vidar Havstad <[e-mail]>).
	+ correct layout of --menu widget, which reduced display width due to
	  logic for --inputmenu being applied whether or not that configuration
	  was used (reports by Javier Kohen <[e-mail]>, Dimitar
	  Zhekov <[e-mail]> and MAL <[e-mail]>).  Fixes Debian
	  #201215.
	+ modify gauge widget to support --begin option (Hans-Joachim Baader
	  <[e-mail]>).
	+ updated pl.po (Jaroslaw Swierczynski <[e-mail]>)
	+ hide cursor while painting gauge.
	+ add auto-sizing logic to gauge widget (reports by
	  Javier Kohen <[e-mail]>
	  and Robert Schubert <[e-mail]>).

2003/07/20
	+ rewrote inputstr.c, allowing it to enter and display wide-characters.
	  Some nonprinting characters such as control/B can be edited as well.
	+ modify timebox to allow user to type numbers into the fields.
	+ change interfaces of dlg_getc(), mouse_wgetch(), etc., to add
	  parameter that returns whether the result is really a function-key.
	  This is needed to work with wide-character curses.
	+ correct computation of week-number in calendar widget (report by
	  Heiner Lamann).
	+ updated configure script macros:
	  + suppress -Winline with gcc 3.3, since it is broken.
	  + fix caching bug in CF_UTF8_LIB
	  + improved script for CF_BUNDLED_INTL.
	+ update config.guess, config.sub

2003/03/08
	+ add null-pointer checks to some malloc calls which were overlooked.
	+ correct logic in dlg_add_result(), which did not copy content of
	  non-allocated buffer to the first allocation (report by Daniel Dupont
	  <[e-mail]>).

2003/03/02
	+ correct an uninitialized value in dlg_add_result() (Debian #182683).

2003/01/30
	+ corrected print_line(), which subtracted the margin twice from the
	  right-limit, making a string wrap unnecessarily (Debian #168823).
	+ correct initial limit-check for arrows in checklist.c, which used
	  the wrong variable, showing the bottom arrow when it should not
	  (Debian #168823).
	+ modify driver to always call show_result(), to simplify updates.
	+ fix several memory leaks, important if dialog is run with a large
	  number of widgets (report by [e-mail] forwarded by
	  Santiago Vila <[e-mail]>).
	+ check if the screen output is actually to the terminal before trying
	  to suppress xterm's alternate screen mode (see 2000/01/18) (report by
	  David Oliveira <[e-mail]>).
	+ use dialog_vars.input_result consistently to return the text which is
	  printed after a widget completes.  In many cases, dialog now
	  allocates enough space to hold the text, rather than use a fixed
	  buffer.  The checklist widget was writing directly to the output to
	  avoid limits of the fixed buffer.
	+ modify dialog.c to also write dialog_vars.input_result if the
	  Help-button was pressed (request by Amon Ott <[e-mail]>).
	+ add hu.po (Arpad Biro <[e-mail]>).
	+ update fr.po, pt.po, pt_BR.po to add strings for "Help" button (patch
	  by Frederic L W Meunier).
	+ fix off-by-one error in menu.c, checklist.c (reported by
	  Tomasz Wasiak <[e-mail]> 2002/9/15 and others:
	  Andrew Gaul <[e-mail]> 2002/11/12,
	  Tobias C Rittweiler 2002/11/19,
	  Arpad Biro <[e-mail]> 2003/1/21).
	+ updated configure script, improving checks for ncurses in various
	  locations, updated NLS script to match lynx.  Added --with-curses-dir
	  option.
	> Tobias C Rittweiler:
	+ make ifdef in mousewget.c consistent with usage in dialog.h
	+ use beep() rather than flash() in dlg_edit_string(), for consistency
	  with the other functions.
	+ change order of buttons so extra button falls between Ok/Cancel.
	+ fix so "dialog --print-maxsize" exits from curses.
	+ add --inputmenu option.

2002/08/14
	+ modify checklist.c and menubox.c to treat the extra button like the
	  "Ok" button by making dialog print the chosen items (request by
	  Tobias C Rittweiler).
	+ add examples checklist6 and menubox6 to illustrate the --colors
	  option.
	+ implement -colors option, which allows one to highlight words in the
	  titles and most text areas with color or video attributes (adapted
	  from patch by Tobias C Rittweiler).
	+ add examples inputbox4, inputbox5 to illustrate how to use the
	  --output-fd option, and how to use dialog without any temporary
	  file at all.
	+ add --output-fd option (Debian #153984).
	+ documented vi-style keys for calendar, textbox widgets in manpage.

2002/06/22
	+ improve mouse handling, e.g., for up/down scrolling in calendar,
	  checklist, etc.
	+ adapted patch by Tobias C Rittweiler <[e-mail]> to add
