REVISION HISTORY ³ JetMail v1.00 (c)1991 by DJ Chuang
                 ³ .QWK-compatible offline mail door for SPITFIRE 3.x

If you've kept up with some of the JetMail public beta versions, you can
review this text file to see when bugs and problems you may have
encountered were fixed.  Please read the newly updated JETMAIL.DOC and
the JETMAIL.FIX documents if you have questions on the functionality of
JetMail.  Briefly, there is a new text file, NEWUSER, that should be
placed in your home directory, JETMAIL.ERR is updated, and you can
overlay the new .EXE over the old one; and two new parameters (LOG and
DONTPOST) have been added since Beta 1.  The remainder of the changes
were program corrections.

1.00 Release - 8/16/91 1:00pm
- Added a "Flags" column to make the message scan look neat.  No more
  cryptic ^ # % symbols.  The only 'cryptic' code now is /NP, which
  means "No Private" messages allowed in that conference.
- Detect when compression utility doesn't generate a .QWK packet.
- Fixed NetSysop default to not display menu; other cosmetic changes.

Pre-release - 8/16/91 12:00am
- Rearranged the method of allocating memory for space to import and
  export messages.  On some systems running MS-DOS 5.0, JetMail
  encountered memory allocation problem, because of DOS 5's new memory
  management.  Refer to JETMAIL.FIX for more details.

Pre-release - 8/15/91 8:00pm
- Fixed potential problem with pointers, if a Spitfire were to have
  over 8000 users. (a sysop's dream! *grin*)
- Added diagnostics for memory allocation.

Beta 8 - 8/14/91
- Fixed RNet compatibility for PCRelay messages in SF when building
  NetSysop .QWK packets. (RNet fixes taglines to conform to a 'standard'
  for QWK-style networks)
- Searching SFUSERS.PTR for user record, sometimes came up with a name
  that mismatched the name in DOOR.SYS.  Just found that DOOR.SYS itself
  contains the user record number.  Rearranged code, and added detailed
  code to track problem if it should occur again.
- Delete XFER_ERR.JET before scanning new .QWK (on certain ocassions, it
  was possible to have an XFER_ERR.JET in the .QWK, tho' harmless, it
  was unsightful)
- Added option <B> in Config User Setup, to include user information,
  which some QWK readers can display.  All the information is not
  absolutely accurate, because there is no strict standard for
  interpreting these variables between QWK readers and doors.

Beta 7 - 8/13/91
- Search SFUSERS.PTR for user record, instead of reading SFDOORS.DAT.
  Sometimes, esp. during auto-pilot/local use of JetMail, a stray
  SFDOORS.DAT file will result incorrect LMR pointers.
- Added "Pointers not updated" message to notify user when .QWK
  transfers fail, and JetMail responds this way.

Beta 6 - 8/12/91
- Compiled with new version of CKIT.  Fixes a potential problem with
  16550 UART, and time displayed in logoff message.
- Build proper header in .QWK for NetSysop packets, for use with
  RNet/QNet.
- Re-coded share-compatible code for sharing files.  The old code
  was causing share violation on some multi-node systems.  Hopefully
  this will clear that up.
- Update LMR pointer only in selected conferences. (older versions
  updated LMR pointers in all conferences regardless). Thanks Steve
  Newman.
- Fixed code in checking file size, which is used to determine time
  needed in transferring a file.
- Fixed response to Overwrite flag during local use.  If the local user
  (or sysop) responds NO when a .QWK is found in the destination path,
  JetMail should 'abort the transfer' and not update LMR pointers.
- Certain TSR (memory resident) utilities may cause JetMail to be unable
  to determine file size and dates.  Please try to deinstall excessive
  or unnecessary utilities; in the mean time, I will search for a
  suitable code replacement.
- Added direct DOS error messages in message scan to try to figure out
  an elusive problem on some systems. (This problem causes some .QWK
  to not contain a MESSAGES.DAT, or to miss scanning messages from a
  certain conference)
- Changed word wrapping to column 80 instead of column 78 on messages
  being export from JetMail.
- During New Bulletins scan, JetMail was searching all the way up to
  100 bulletins, whether they exists or not.  For the average BBS that
  might have only a dozen bulletins, this was painstakingly slow
  (because JetMail was checking file dates on non-existing files).
  JetMail now scans up to the last sequentially existing bulletin,
  that is, if you have 3 bulletins, JetMail scans bulletins 1, 2, and 3
  and continues to the messages scan (instead of looking up to 100).
  However, if you have bulletins numbered 1, 2, 3, and 5, and bulletin 4
  doesn't exist, JetMail will not scan bulletin 5.
- JetMail no longer deletes SFDOORS.DAT (and related files) upon normal
  logoff in JetMail. I'm awaiting a SF development for better way of
  handling door logoffs; deleting SFDOORS.DAT caused user information to
  be lost, so if a user used 30 minutes in SF, then logged off in
  JetMail, the time was not charged to his account!  (JetMail was
  deleting SFDOORS.DAT to have SF not print the 'improper logoff'
  message in the caller log, but deleting SFDOORS.DAT is not a good
  solution)

Beta 5 - 8/5/91
- Compiled with new CKIT toolkit.
- Added automated new user initialization, which sets new JetMail users'
  last message read pointers so they get the last ten messages from the
  default recommended conferences, as defined in the .CNF file.  Be sure
  to place the NEWUSER text file in the JetMail home directory, and
  edit it to contain your system specific information.
- Adjusted code to watch for .PNT uploads, to make sure pointers
  are valid.
- Adjust high message number for new message scan when messages are
  posted via JetMail REP.

Beta 4 - 8/4/91
- Fixed sporadic error in setting Net-Mail flag on messages posted
  via JetMail.  NOTE: JetMail will copy the Net-Mail status flag of
  the conference that the message is posted in.  Be sure the Net-Mail
  flag is set ON in your echo/network conferences.

Beta 3 - 8/3/91
- Fixed code to watch for maximum messages scanned.
- Fixed Pointer Upload command to write message pointers to .LMR files
  after upload.
- JetMail Config User Setup was not displaying Include flags properly.
  Fixed.
- Added user parameter for Maximum number of messages per conference
  (NOTE: Be sure to tell your users [using JETNEWS would be a good way]
  that some readers only handle up to 200 messages per conference, and
  set the user's JetMail configuration using command 'C' accordingly)
  The JETSM editor does cannot edit this parameter yet.
- Removed some debug information after download/uploads.
- When a user tries to post a private message in a public-only
  conference, JetMail is supposed to skip from posting it.  But
  the code didn't work right.  Fixed.
- Fixed CRC32 calculation, so Spitfire's message scan for your mail
  will properly detect new messages posted via JetMail.  Thanks
  Bob Browne.
- Moved "Loading Pointers" to be a part of Initialization.  (Before Beta
  3, JetMail would load message base pointers upon the first use of
  either Select Confs or Download Packet commands)
- Redone offline configuration messages processor.  Added support for
  subject-line offline configuration messages, and they may be addressed
  to JETMAIL, QMAIL, or MARKMAIL.  This should cover all the reader that
  have 'automatic' config commands.
- Added DONTPOST= parameter for JetMail .CNF file.  Specify YES
  to NOT post messages addressed to invalid conferences and no-
  access conferences.  By default, if not specified, JetMail will
  post messages designated for invalid conferences to Conference 1.
  (an invalid conference is non-existing conference number; no-access
  conference is when the user doesn't have access to a conference
  because of security level)
- Added LOG= parameter for JetMail .CNF file.  You may specify a
  separate log file if you do not want JetMail usage log to be recorded
  to your main Spitfire callers.log. (i.e: LOG=\JETMAIL\JETNODE1.LOG)
