This file lists (in reverse chronological order) the updates that have
been made to the MIT-LCS Interactive Network Map program.  The descriptions
here tend to be slight generalizations.  See the edit histories in individual
files for details.  On demand, I can produce diffs between most versions.
This only lists non-trivial changes.

13-May-91	Release 5.5 issued.

 3-May-91	Added support to "write geometry" for the new point-to-point
		nets.  Also made geometry not show addresses if unneeded.

28-Apr-91	Release 5.4 issued.

26-Apr-91	Reworked most of the documentation files...

25-Apr-91	Fixed bugs in "snmp neighbors" command and ping.  "sn n" died
		if there were more than 22 neighbors and ping failed sometime
		after the 40,00th was launched (but it recovered again at
		65,536).  Minor tidy to all documentation.

19-Apr-91	Release 5.3 issued.

 1-Apr-91	PostScript title support cleaned up and key added.  Added
 through	point-to-point style networks.  Improved list of variables
19-Apr-91	(format better) and help for set (prints legal values).  Added
		a resource for highlighted host foreground, this is most
		useful because it allows highlighting by reverse video on
		black and white displays (this is the default).
		Added point to point style for networks

11-Mar-91	PostScript modified to print titles.

 1-Jan-91	Release 5.2 issued

 1-Jan-91	Put in submitted bug fixes to ICMP and SNMP including some
		type-clash errors in arg lists and not including config.h in
		the ICMP build so the nifty parameter isn't seen.  Cleaned up
		the includes in the SNMP module so the bogus "-I." could be
		removed from the list of includes, fixed Makefile.in to delete
		it.

30-Nov-90	Rearranged initial window creation so placement works in GWM
		and when no window manager present (at least, maybe others)

25-Aug-90	Improved error messages produced by DBG_FILES when parsing
		host file.  The name of the host in error is now printed.

17-Aug-90	Release 5.1 issued

17-Aug-90	Fiddled with Makefile structure some more.  Added options for
		one of the users configurations, these are redundant and the C
		compiler will effectively ignore them elsewhere...
		Added subdir of useful (but unsupported :-) auxiliary stuff.

15-Aug-90	HP-UX conditionals added.  Removed "testing" comment from SNMP
		command.  Don't print geometry if not set.  Added space to
		help listings for longer commands.

10-Aug-90	Added type to routes and speed in interfaces.  Changed which
		types were acceptable to "SNMP Neighbors" command (was only
		Remote, now any but Direct), this gets around a bug in the
		Proteon agent code.

 9-Aug-90	Hardcopy routines (Tek and PS) check AlreadyPlaced flags in
		case a redisplay hasn't happened (tty mode or load/write in a
		take file).  Networks were never setting it, that was added.
		Wrote a script to do configuration management (a bit).

 8-Aug-90	Added "set hardcopy ps/tek" and removed "write tek" command.
		Added cd command (useful as  default output directory).  Also
		removed a case that couldn't happen in DescribeMachine.

 2-Jul-90	Added more SNMP conditionalization, had missed stuff added to
		check command.  Added conditionals to debug code so
		ineffective flags don't get listed in "debug ?", etc.

21-Jun-90	Added SNMP Neighbors command.  Printing an unplaced host
		correlates networks if the flag for connectivity debugging is
		on.  This makes it not print as "[network not displayed]" if
		in fact it is.

17-Jun-90	There was a bug when run under dxwm or gwm.  There were no
		ConfigureNotify events, we don't know the size and prompt
		clears screen.  For now it just runs assuming we got the size
		we asked for until the first ConfigureNotify.

16-Jun-90	Release 5.0 issued

15-Jun-90	Made keypad "Enter" key synonym for <Return>.  Reorganized
		host description somewhat.  Including "summarizing" namelist.
		Various cleanup.  Redid commands: Hostat->Status,
		Select->Host.  Added variables, only one now: snmp_auto.
		Fixed bug that loading files never closed the file, eventually
		running out of descriptors and crashing.  Add retransmissions
		to SNMP, other minor stuff.  First round SNMP finished.

12-Jun-90	Added SNMP.  Based originally on Chuck Davin's contribution,
  thru		but eventually reorganized to fit a bit better, partly with
15-Jun-90	Chuck's help.  Lots of minor fiddling with other parts.

20-Mar-90	Added pxl2rgb to remove X from TEK module.
		(From report by P. V. O'Neill)

13-Mar-90	Conditionals for compatibility with DG/UX added.

11-Mar-90	Release 4.5 issued 

10-Mar-90	Cursor changes to stopwatch when working.

 6-Mar-90	Minor work (mostly removing lint)

 5-Mar-90	Minor cleanup in code, major work on supporting documentation
		for all the changes that have been made.

10-Feb-90	Cleaned up ICMP some more.  Added some needed casts for Sun-4,
		but it still doesn't ping (but it does compile now).  Various
		loose ends (obsolete functions and vars, etc.)  Made startup
		code default if there was no map.cf (or whatever) file.

24-Jan-90	ICMP code cleaned up and "debug ICMP" added.  Initialization
		of ICMP now fails soft, should be able to look but not ping
		when suid fails (and not root).  Added a field to Geometry to
		disambiguate hosts without requiring full name on display.
		Added test so blank input lines in ttymode don't produce
		errors, but automagic awaits GetLine...  Control-U removes
		input in display mode.  Taps to deleted nets go away.  Added
		take and echo commands.

 9-Nov-89	Bug in icmp.c fixed.  It didn't reject replies to old pings
		that were still outstanding.

15-Sep-89	Made Networks without a name print better, both in the "debug
		connectivity" and when queried directly.

12-Sep-89	Improved debug: Made dbg_lookup do partial match; added
		heading to help message; added "connectivity" option.

22-Aug-89	added return(val) to end of PSopen for hc on RT which doesn't
		return value of last statement.

 2-Aug-89	Release 4.4 issued

 1-Aug-89	Patched around B&W bug, needs more later.

29-Jul-89	Release 4.3 issued

29-Jul-89	Cleaned up various doc files, improved find_file.

 8-Jul-89	Made file not found errors in "Load Geometry" command soft.
		The "Help" key helps partial input.  Added debugging of events
		and color determination (X11 only).  Added a debug option for
		"state" that tells about major state operations of the
		program, steps in startup, major events not otherwise
		reported.

29-Jun-89	Added find_file and made Hosts, Geometry and PS.header use it.
		Fixed minor bugs in hardcopy parts (due to X10 vs X11 font and
		text stuff, these may be wrong on X10 now).  Added "debug
		files" and made messages in Parse routines conditional on it.
		Added option for boxes around titles (only on display for
		now).  Added commands associated with titles, most useful
		right now is "Load Geometry", click & go.

24-Jun-89	Cleaned up and expanded general info files.
		Added conditional that should deal with old vs new raw IP.

 6-Jun-89	Added debug, undebug and list debug commands and stuff to
		support them.  Created debug.? files.

27-Mar-89	Cleanup in FlushGeometryInfo, free more stuff (still not
		everything), do it more orderly.

23-Mar-89	Cosmetics from report by Chris Tengi.  PostScript now puts a
		comment at the end of the common header file.

23-Mar-89	Release 4.2 issued

23-Mar-89	Added table_addresses field to Host structure to allow
		Geometry to override but put back later.  Added "Version" and
		"Load Geometry <file>" commands.

23-Mar-89	Added waiting flag so redisplay in middle of things gets
		correct bottom line.

22-Mar-89	More X11 window creation improvements.  Use the user specified
		geometry, pick a cursor.  Open display early by prescan of
		args.

21-Mar-89	[Chris Tengi] Improved X11 window creation somewhat.

20-Mar-89	Release 4.1 issued

20-Mar-89	Minor cleanup from report by P. V. O'Neill, including byte
		ordering in same_inet & WriteAddress and added pxl2rgb to
		remove X from TEK module.

18-Mar-89	Release 4.0 issued

17-Mar-89	Added config file.  Fixed up greeting stuff to aid variable
		version numbers.

 4-Mar-89	Finished isolating display stuff to X module.  Added option
		aliases for compatability.  No longer precompute Vertex list
		since this is dependant on output technology, now computed
		when needed.  Made filled in rectangles use macro in
		PostScript.

 1-Mar-89	Release 3 issued (first public release, requires Chaos, X10)
