GremNOS v0.3d
=============

These are brief release notes for GremNOS v0.3d.  GremNOS is a variant of
KA9Q, based on Demon Internet's version 2.16d, and was originally developed
by Graham E. Kinns up to v0.2 in November 1997.  It has subsequently been
tweaked and extended slightly by Pete Disdale and Simon Turner.

The previous public release of GremNOS was v0.3b; v0.3c was an interim build
that was never released.

Visible changes between v0.3b and v0.3d are:

   1.	SMTP server and NNTP client: ASCII 0 ("NUL") characters embedded in
	incoming SMTP mail messages and NNTP news articles are translated to
	255.  This works around bugs in both the SMTP server and NNTP client
	which would otherwise corrupt the stored messages, and would stall the
	SMTP server completely if the NUL byte was in the last line of the
	message.  When such NUL bytes are fixed, a note is written to the log
	file (and the screen, if in verbose mode) stating the message ID and
	the number of NULs fixed.

   2.	NNTP direct posting: a new command "nntp showqueue" displays the queue
	of articles waiting to be posted; the posting code now uses file
	locking (the lack of locking in earlier versions was an oversight); in
	"nntp post only" mode, it now stops early on (before contacting the
	server) if there are no articles to be posted.

There have also been one or two small tweaks and standardisations; and I've
added various other bits of functionality to suit the peculiarities of my own
use (I run an increasingly baroque stripped-down packet-driver-only version),
but they are all disabled in the distributed configurations and make no
difference to the binaries.  (If you're *really* curious, look at the source;
the only bits that might be of any interest to others are VAR_MOREROWS,
NNTPCLI_CONFIG, SMTPSERV_CONFIG, POSTMASTER_ACCEPT and POSTMASTER_KNOWN.)

Source code (all those files which have changed since GeK's 0.2 release) and
various compiled binary builds are available.  Note that, in order to enable
the direct NNTP posting option in the v0.3 Large build, I was forced to remove
the MAILBOX option from that build to keep the program compilable.  If anybody
needs a Large build with the MAILBOX option, contact me and we can sort
something out.

The source code files which have changed since v0.3 are available in
gnos03ds.zip; you will also need the full v0.2 source, and the changes between
v0.2 and v0.3 (gnosv03s.zip), to compile the program.

The following binary builds are available (Zip files contain NET.EXE only):

  lrge_03d.zip	Large - this is the replacement for the standard 'large'
		version of Demon KA9Q v2.16d, including NNTP posting, packet
		driver support, FTP server, RIP, Z-modem, etc. but (for v0.3)
		*excluding* the old telnet mailbox.

  lite_03d.zip	Lite - this is a cut down version aimed at dialup use which
		should have considerably more free memory available than the
		Large model. It excludes packet driver support, telnet
		mailbox, FTP server, RIP, Z-modem, finger server, DOS shell,
		remote client & server, ttylink server, DNS server, packet
		tracing and IP filter but includes additional dialler logging
		commands and John Washington's http URL grabber.

  twlt_03d.zip	TW-Lite - this is the TextWin version of the Lite model;
		feature list is otherwise exactly the same as Lite.

  pklt_03d.zip	PK-Lite - this is the Lite build with packet driver support
		added.

  tplt_03d.zip	TP-Lite - this is the TextWin version of the PK-Lite build.

I'm sure this is obvious, but please note that the "Packet + Lite" build of
GremNOS, which is called "PK-Lite", has nothing to do with PKWARE's
executable compression software PKLite.

Send e-mail to <gremnos@twoplaces.co.uk> if you have any queries, requests,
suggestions etc.
