2.11 to 2.12
    1.	Extra functionality for XTerm mouse report mode.  If mouse reporting
	is enabled (the application will handle mouse events) the normal
	scrollbar operation is disabled -- instead rxvt sends UP/DOWN for
	the arrow buttons and PageUp/PageDown when Button1 or Button3 are
	clicked on the scrollbar.  Use Mod1 (Alt) key to get the normal
	scrollbar/arrow button actions and also to get the normal selection
	functions -- so that you can still cut/paste between X applications.

    2.	New colour possibilities -- 16 colours.  Instead of using fatter
	characters, a bold attribute now uses a brighter foreground colour.
	Similarly, a blink attribute will use a brighter background colour.
	It is also possible to choose these colours through the resources
	(color0 -- color7) permit specification of the ANSI colours (black,
	red, green, yellow, blue, magenta, cyan, white), the resources
	(color10 -- color17) are the brighter bold/blink equivalents.
	Define USE_FAKE_BOLD to disable.

    3.	Extensive clean-up of source and headers to separate
	interdependencies, remove unused variables.  Introduced static
	variables wherever possible to limit scoping and reduced the number
	of external variables.

    4.	Allow NumLock to toggle on/off the application keypad.

	Backspace sends '\b', Ctrl-Backspace sends '\177'.
	Define BACKSPACE_AS_DELETE to reverse these values or use the
	escape sequence:

		ESC [ 36 h		Backspace key sends BS
		ESC [ 36 l		Backspace key sends DEL

	XK_End used to send "\033Ow", which is identical to XK_KP_7 and
	confuses EDT-type editors. Now,
	Home = "\033[7~"
	End  = "\033[8~"

	Changed Alert & Secure keys from Alt-i & Alt-s to Alt-I & Alt-S so
	they aren't so easily toggled.

    5.	Extra keystroke info.  Pass Control and Shift indicators for
	function keys (similar to the XJed editor)
	eg,
		F1	= ESC [11~
		C-F1	= ESC [11^
		S-F1	= ESC [11$

	also, pass indication of shift status for arrow-keys
	eg,
		Up, Down, Right, Left
		  = ESC [A, ESC [B, ESC [C, ESC [D
		S-Up, S-Down, S-Right, S-Left
		  = ESC [a, ESC [b, ESC [c, ESC [d

	You wouldn't be able to use these keys for termcap/terminfo
	applications, but the key sequences are available for remapping
	within an application.

    6.	Added configure.h which is included by each source file and by the
	Imakefile.  Common compilation defines are now all contained in
	configure.h with minor system defines remaining in Imakefile --
	makes it much easier to configure.  Used XCOMM macro in Imakefile so
	that it actually works.  Also added defaults.h for defining
	user-specific startup defaults.

    7.	Added rxvt.ref to provide documentation of the various terminal
	sequences that are processed.  Updated man page to reflect changes.

    8.	Use xterm-style -/+ to turn on/off options, rationalized resource
	names to more closely resemble xterm.

          				cutchars: <string>

    9.	Fixed Button actions for XTerm-style scrollbar so that Button1 and
	Button3 do different things as they are supposed to.  Replace -/+fat
	with -/+sb and -/+arrows for more consistency with XTerm. Decreased
	width of `fat' scrollbar (make closer to xterm) and increased width
	of `thin' scrollbar (arrows too small) -- they are now the same
	width.  Also made it possible to remove the scrollbar altogether.
	Added a visual bell.

	Added many more defines to further reduce code size for various
	cases, see "configure.h".  It is also possible to alter settings in
	"defaults.h" for configuration options that will only affect
	screen.c and xsetup.c, this should help with compile-time
	customization for those who don't want to use Xdefaults.

	Added the define REPLACE_SELECTION_NEWLINE to make the substitution
	of newlines with carriage returns for selection pasting a
	compile-time option.

   10.	Fixed the graphics samples so that if you want to it's actually
	possible to compile them.  Added -name command-line option so that
	it's possible to select different sets of resources.

   11.  Integrated initial support for X11 mouse reporting and added
	Shift + Function Keys support.

2.10 to 2.11
    1.	If NEW_COLOR_MODEL is defined in screen.c, the new model I described
	in an earlier email is used. (apparantly there are two, slightly
	differnt models for using color extensions in a vt-compatible
	terminal. This flag lets you switch.

    2.	If XTERM_MOUSE_REPORT is defined in command.c, mouse reporting is
	turned on/off via the appropriate escape sequences.  XTerm already
	provides this support.

    3.	If .Xdefaults does not exist, .Xresources is searched for.  It seems
	that many here use .Xresources.

2.09 to 2.10
    1.	Really fixed the color problem (?) Got color-ls, and it works now.
    2.	Added patch to allow run-time selection of font list.

2.07 to 2.09
    1.	Fixed some color-usage errors.
    2.	Added double and triple-click support
	compliments of ah@doc.ic.ac.uk (Angelo Haritsis)
    3.	Added Print Screen capability, as in most vt-100's
2.06 to 2.07
    1.	Fixed problems with rxvt screwing up tty permisssions (?)
2.03 to 2.06
    1.	Fixed a limit which imposed a maximum width for the
	terminal window of 255 characters. There is no limit now.
    2.	Made provision for applications to get mouse-click feedback
	when user clicks in a graphics window. See graphics_sample
2.02 to 2.03
    1.	Fixed memory management just a little.

2.0 to 2.02
    1.	Bug fixes for color and graphics.

1.97 to 2.0
    1.	Added ANSI color support. Compile with -DCOLOR
    2.	Added a graphics mode. Compile with -DGRAPHICS
1.96 to 1.97
    1.	Bug in refresh() which was causing slow refreshes after
	clear-screens was fixed. Showed up during emacs start-up.

1.95 to 1.96
    1.	rxvt did bad things if it received mouse - Motion events
	without a preceeding button-press. Fixed.
1.94 to 1.95
    1.	Created a substitute for XGetDefaults, which seemed to account for
	1/2 to 2/3 of the memory used by rxvt (according to the SIZE field
	of ps output). My substitute only reads the .Xdefaults file. Compile
	with -DFAKE_RESOURCES to get my mini- XDefaults handling,
	-DREAL_RESOURCES to keep XGetDefault.

1.93 to 1.94
    1.	Fixed some minor long-standing errors in the vt100 emulation.
    2.	Fixed ALT-<char> handling in command.c
    3.	Fixed minor bug with start-of-selection location.
    4.	Added xterm-type "extend selection" feature using
	mouse button 3. Button 1 always starts a new selection. Button3
	tries to extend the current selection if possible.
    5.	Fixed problem with bold-face fonts overflowing into
    	the next character for some fonts.

1.92 to 1.93
    1.	ran gprof to find bottle-necks in the code. Halved user
	time, but had little effect on total time required to
	update the display. Seems worth keeping for the more efficient
	user-time, though. At this point, I think that most of the elapsed
	time is spent waiting for input or waiting for the X buffers
	to flush.
    2.	Used to refresh the screen every 2.2 screen-fulls during
	flat-out scrolling. Really cuts down on scroll-time. Now,
	refresh every screen-full (or when there's a pause in activity),
	but when flat-out scrolling starts, decrease the refresh period,
	so that its every 10th screenful after a little while. This has
	no noticeable visible effect, since the scrolling text is
	absolutely unintelligible anyway, but will improve the scroll
	"feel" when doing just one or two screenfulls, ie in an ls -l.
    3.	Surrounded  the code which uses XCopyArea with #ifdef's
	I have never seen this help performance, but I think that there
	may be some video-systems which benefit from this, particularly
	in a full-screen editor or slow scrolling type of setting.
    4.	Performance in flat out scrolling, text only, on a sparc-10,
	displaying rxvt on an HDS x-terminal:
	  nation@snoopy>/usr/bin/time rxvt -e cat k
		6.1 real         3.1 user         2.5 sys
	  nation@snoopy>/usr/bin/time xterm -e cat k
		40.8 real         4.6 user         3.4 sys

1.91 to 1.92
    1.	Added greek-keyboard support patches.
1.85 to 1.91
    1.	assorted minor patches
1.82 to 1.85
    1.	Fixed ESC c handling.
    2.	Fixed minor selection handling bug.

1.81 to 1.82
    1.	Fixed slow refresh during selection process
    2.	Fixed problem of not correctly clearing selections of 1 character.

1.80 to 1.81
    1.	Fixed some scrolling problems, problems with partially obscured
	windows.
    2.	Added some neat debugging capability in debug.c
    3.	Patched up rclock.

1.74 to 1.80
    1.	Fixed core dump from selecting past the bottom of the screen
    2.	Fixed a few escape sequences, per the vttest program
    3.	Broke and fixed handling of moved/resize/new-font handling.
    4.	Still can't change tab stops correctly.
    5.	Ran vt-100 test suite. Added capability to change tab stops
	and enter reverse video, and to switch from 80 to 132
	columns and back. Fixed a seg-fault in scroll().

1.70 to 1.74
    1.	Fixed cursor drawing errors.
    2.	Improved smoothness of scroll-back operations.
    3.	Applied some SVR4 patches.
    4.	Applied HPUX patches, and a few cursor display patches
    5.	Fixed up font-changing routines a bit.
    6.	Fixed a scrolling problem for windows taller than the scroll-back
	buffer.

1.6 to 1.7
    1.	Fixed the problem with random rendition flags in the scroll
	back buffer
    2.	Fiddled with re-drawing on the scroll-bar, and with
	how often refreshing occurs.
    3.	Incorporated some AIX patches.
    4.	Included #ifdef'd changes to support vt100 printer.
    5.	Fixed send_string routine, so that it doesn't loose
	data.
    6.	Complete re-write of screen.c
1.5 to 1.6
    1.	Removed all use of a seperate bold font. Now uses
	over-striking exclusively.
    2.	Added some more optimizations for drawing speed when
	the window is re-sized or moved.
    3.	Implemented speed ups in screen.c

1.47 to 1.48
    1.	Cleaned up re-drawing on expose events, so rxvt only
	re-draws the newly exposed parts of the screen.
    2.	Fixed backspace, which must have broken in 1.45.
    3.	Added command line option of iconic startup.

from 1.45 to 1.47
    1.	Incorporated improved bsd utmp handling from
        dperry@ringer.cs.utsa.edu (David Perry)
    2.	Fixed a very minor bug where the solid-cursor can leave a
    	a bit of a ghost when you resize the window. Its stupid,
	but it always bothered me.

from 1.4 to 1.45

    1.	Fixed scrolling error when switching to larger fonts
    2.	Fixed utmp-entry removal for SYSV type systems.
    3.	Icorportated patches for FreeBSD and svr4
