2.21a3 to 2.21b*
\---------------
     1. From: Conrad Link <[e-mail]>
	Fixed a bug in the OffiX Drag and Drop support.
	rxvt inserted two instances of directories or links when they 
	were dropped onto rxvt.
	
     2. From: <[e-mail]>
	Fixed a bug that makes rxvt getting constantly "NoExpose" events
	which it is not handling.

     3. From: Mark Olesen <[e-mail]>
	Fixed a bug that caused rxvt to hang indefinitly waiting for a 
	terminating ^G on an XTerm `ESC]' sequence.

     4. From: Bernard PERROT <[e-mail]>
	      Mark Olesen <[e-mail]>
	Fixed a bug that prevented to handle DEC VT2xx's ApLineDel correctly

     5. From: <[e-mail]>
	      Mark Olesen <[e-mail]>
	Now the Shift/Ctrl cursor key mappings are enabled regardless of
	App-Cursor settings

     6. From: Kai Petzke <[e-mail]>
	Fixed a bug with respect to cursor movement. rxvt now handles the
	'G' and 'd' sequences correctly

     7. From: Geoff Wing <[e-mail]>
	Fixed a couple of things in utmp.c 

     8. From: Denis N. Antonioli <[e-mail]>
	Added the "-tn" option and corresponding Xresource variable "termcap".
	This option specifies the name of the terminal type to be set in the
	TERM environment variable. 

2.20 to 2.21a*
\-------------
     1.	Oops, forgot to include time headers in menubar.c

     2.	Finally got the correct DEC sequence to toggling the behaviour
	of the backspace key and removed the other non-standard ones.
	If anyone has a listing of DEC escape sequences they'd like to
	donate ...

     3.	Fixed a bug that prevented an XPM file from being found if it
	were specified with an absolute path and a geometry string.
	Made the default scaling zero (tiled) since this is by far the
	most popular use.

     4.	The Motif-style scrollbar is back as a compile-time option.

     5.	Added BUGS file and (thankfully) moved coordination of the
	project to Oezguer Kesim <[e-mail]> who also
	has a mailing list for rxvt development

	Rxvt Workers <[e-mail]>

	To subscribe to the list send email to
	<[e-mail]> with the body: subscribe

     6.	Semi-retirement and finish my thesis ... bye for now - /mark

   --- Oezguer started working on rxvt

     7. Fixed a bug in the new menubar-feature. There were several unchecked
	strings strcpy'ed which caused rxvt immediately to dump core.

     8. From: Robert Bihlmeyer <[e-mail]>
        Fixed a bug in rclock.c which prevented it to compile correctly.

     9. From: Mark Olesen <[e-mail]>
        Overstrike boldfonts and pixmaps now work together without pixel
        droppings on the screen (at least under Linux).

    10. From: Mark Olesen <[e-mail]>
	Modified autoconf support: memmove() replacement function
	supplied for those systems that need it, libXpm should now be
	correctly found (set in src/Makefile *not* in config.h)

    11.	From: Mark Olesen <[e-mail]>
	Converted doc/rxvt.ref to HTML format.
		doc/html/refer.html = master copy
		doc/refer.txt  = text version saved using Netscape.

	All HTML documents are put in here, to ease installation
	elsewhere.

    12.	From: Mark Olesen <[e-mail]>
	Moved some file search function from main.c and some string
	functions from xdefaults.c to misc.c.

	Changed the implementation details so that `keysym' resource
	is also available as a command-line long option ... even if
	you have compiled with USE_XGETDEFAULT.

    13.	From: Mark Olesen <[e-mail]>
	When a new pixmap is loaded, revert to the default scaling.

    14.	From: Mark Olesen <[e-mail]>
	Reworked the menubar to permit multiple menubars in a circular
	linked list (and all the management functions that entains)
	and new functions including the following:

		* reading from files
		* dumping all the menubars
		* clearing a menu (without removing it)
		* setting a backgroudPixmap
		* and many other features.

	The menu syntax has changed very slightly from the last
	version, but now provides greater flexibility ... see
	refer.html for details.

	Added the `menu' resource/long-option so a startup menu
	can be specified. eg,
		rxvt -menu my.menu -e rlogin machine -l user

2.19 to 2.20
\-----------
     1.	You can now add snazzy looking menus to any plain (non-X) text
	application.  At the moment, the menuing system is simple but
	functional.

	The syntax for controlling the menubar is documented in
	doc/rxvt.doc, but note that an XTerm sequence `ESC ] 10; Pt
	BEL' is used so menus created for rxvt will be ignored by an
	ordinary XTerm.

	It provides sub-menus, click-and-drag, and even some user
	definable `quick' arrows keys.  However menu manipulation
	could use refinement to permit multiple menus to be defined --
	and the menu refreshing could also use some improvement, but
	it can be extended and refined later as required/desired.

	The files doc/menu.sh and doc/jedmenu.sl show sample
	implementations of menus.

	  -->	It compiles and runs on my machine (AIX 3.2.5)
		but THIS IS CONSIDERED BETA (or even ALPHA) CODE!

     2.	DEC private modes: Bug fix for 's'ave and 'r'estore parameters,
	added a 't'oggle parameter to DEC private modes.

     3.	Made Backspace key selectable with DEC private mode
	ESC [ ? 36 h/l/s/r/t (high/low/save/restore/toggle)

     4.	Changed the way the scrollBar is realized to permit on-the-fly
	toggling of the scrollBar display and added a DEC private mode
	escape sequence for that.  Smoother redraw of scrollBar.
	Better proportions for the arrows allows a slightly narrower
	scrollBar.

     5.	Added support for XTerm font changing sequence:
	`ESC ] 50; Pt BEL', with (as usual) a few extras.
	See doc/rxvt.ref

     6.	Adapted experimental XPM buffering from that supplied by
	Carsten Haitzler <[e-mail]>.

     7.	Replaced `wait' with `waitpid' in src/command.c::Child_signal
	to avoid a race condition and permit use of pclose() on SunOS.
	Patch provided by <[e-mail]>, Thanks John!

     8.	For easier XPM handling, added `path' resource/long-option and
	substantially enhanced pixmap scaling to provide very exact
	control over scaling and positioning of the XPM background
	image.  The XPM XTerm escape sequence has been extended to
	provide a convenient facility for on-the-fly rescaling.
	Export COLORTERM="rxvt-xpm" instead of COLORTERM="rxvt"

     9.	Added export COLORFGBG to give hints to color applications.
	Typically one of these values is exported, in which `fg' and
	`bg' are numbers 00-15:

	COLORFGBG="default;default"
		-fg -bg colors don't match any of color 0-15

	COLORFGBG="fg;default"
		-fg color matches color 0-15, but -bg color doesn't

	COLORFGBG="default;bg"
		-bg color matches color 0-15, but -fg color doesn't

	COLORFGBG="fg;bg"
		-fg -bg colors match color 0-15

	When compiled with XPM support, the last two values are
	rendered as follows:

	COLORFGBG="default;default;bg"
		-bg color matches color 0-15, but -fg color doesn't

	COLORFGBG="fg;default;bg"
		-fg -bg colors match color 0-15

    10.	Disable Shift+Prior/Next and scrollBar if saveLines == 0.
	Slight change to key-processing so `shift+meta+key' and
	`shift+ctrl+key' gets processed as `shift+key'.  This provides
	a way to avoid interpretating `Shift+Prior', `Shift+Next', and
	`Shift+Insert'.

	Also, added DEC private mode sequence `ESC [ ? 35 h/l/s/r/t'
	to disable Shift+key interpretation.

	Provide for Ctrl+Shift+<KEY> combinations for function keys.
	See doc/rxvt.ref

    11.	Always match long-option names, even when only preceded by a
	single -/+.

2.18 to 2.19
\-----------
     1.	Minor alteration to input mode for Kanji processing.

     2.	rclock: -adjust option, support for exec on startup syntax,
	date format may now also include the century

     3.	Made mouse double-click respect autowrap lines.

     4.	Added marks for folded editing.

     5.	Added Offix DND (Drag 'n' Drop) protocol.
	Added support for XA_TARGETS.

     6.	added Carsten Haitzler <[e-mail]> XPM patches to load
	an XPM file for the background of the terminal window.
	Uses resource `Rxvt.backgroundPixmap' or long-option
	`--backgroundPixmap'

     7.	Use these (XTerm) keybindings exclusively and remove the old
	equivalent bindings:
		Shift-Prior  = scroll up
		Shift-Next   = scroll down
		Shift-Insert = paste mouse selection

		Shift-KP_Add      = bigger font
		Shift-KP_Subtract = smaller font

2.17 to 2.18
\-----------
     1.	Check for NULL pointers in command-line processing (oops)
	Also fixed processing of `hidden' arguments such as -d, -g, -T

     2.	Fixed terminfo hpa/vpa: was `\E..' instead of `\E[..'
	added invisible cursor (ESC[?25h / ESC[?25l)

     3.	Fixed broken kanji characters (?? and disappeared cursor box ??)
	thanks to <[e-mail]>

     4.	In privileges(), changed setuid/setgid to seteuid/seteguid so that
	it's possible to switch back to root later.

	Perhaps fixed svr4 problems (reports no tty, no job control) in
	get_tty() ... need to detect these SVR4 features in the configure
	script.

     5.	Restored scrollColor, topShadowColor, bottomShadowColor resources
	that somehow got lost between the beta and release versions.  For
	monochrome displays, fixed scrollbar so it will be visible and
	suppress color changes.

     6.	Final? iteration on selection.  Store selection text with LF
	line-endings but paste into rxvt with CR endings.  Selection now
	preserves the newline when trailing space is stripped from
	non-autowrap lines.  Compile-time support for using a keystroke to
