* Fixed bug in handling of suspended events (in case of an event hook DLL)
  while there is an ongoing data transfer.

Version 2.3a released 7 October 1997
------------------------------------
* Fixed bug in NLST and LIST commands (for dir listing) which prevented

* Added support for the SITE INDEX command (only in the 32-bit version)
  as used by Fetch.
* Fixed bug in total file transfers count as shown in the status bar.

* The STOU (=STOre Unique) command now handles long file names in Win95 and NT.
* Changed compilers from Borland C++ 4.52 to BC++ 5.02 for the 32-bit version.
  This necessitated several code changes.
* Changed code so the maximum path length for the 16-bit version is 80
  characters. This is conform the Win16 maximum path length. Longer paths
  caused crashes in Win16 functions.
* Tray icon will now disappear by itself after exiting Serv-U.
* Added "Notes" field to the user and group setup for notes about each user.
* Logging to screen and file can now be separately specified.

  removed, and 'make' access to the destination path.
* The maximum transfer speed can now be set for each user via the 'setup -
  users - miscellaneous' menu.
* Partially uploaded files can be automatically deleted via a 'setup -
  server' menu option.
* In case a client closes the command connection while there are ongoing
  transfers this is now properly logged and passed to the event notification
  mechanism.
* Files are now kept open during transfers. This means files being uploaded
  show zero length during the upload.
* The reply message after a dir listing or file transfer now shows the client
  his/her ratio and quota status (if the client is using ratios and/or quota).
* Added SITE command to the event hooking mechanism. Any SITE command can
  now be intercepted by an event notification DLL.
* Fixed bug in system tray menu (Win95) when Serv-U gets started automatically
  after system startup.
* The CWD ('change working directory') command no longer actually changes
  the Serv-U task's current directory which caused locking of the dir in NT.
* Added .ini file option to avoid logging of certain clients from IP numbers.
* Closing Serv-U from the system menu (or the 'x' in Win95/NT4) now minimizes
  the window in case there is a tray icon. Exit the server from the tray menu.
* The string "%20" in paths is converted to " " (=space) to please MSIE.
* There no longer is any 'hard' limit to the maximum number of IP homes.
* Serv-U now shows all the IP addresses it listens on at startup.
* Upon startup a file IPSERVU.TXT is created in the Serv-U program dir with
  all the IP addresses it listens on. This file is updated every 5 minutes.
  Through a .ini file option the interval and file name can be changed.
* When restoring window from the tray-icon (Win95/NT4) the log will now scroll
  to the end.
* When running as a Win95 system service there is no longer a regular icon
  if the user logs out and back into the system again.
* External access verification DLLs now receive the SRVU_IPAccess event,
  also when no IP access rules were present.
* In case Serv-U is started for the first time, but with a KEY.TXT file
  present it will no longer ask for the try-out option but read in the key.
* Users with no password (ie. 'Password' entry in the .ini file explicitely
  set to nothing) are logged in immidiately after the USER command.
* Users can be given an empty password (ie. no password required when logging
  in) by entering "<<None>>" in the password field of the user setup.
* To create or delete directories the user now needs the appropriate access
  to the parent of the dirs that are being created/deleted.
* Users with setting "allow login when max. no. of users is reached" now also
  have no time-out after logging in.
* Server now switches to 'crippled' try-out when try-out time is up.
* When the version is out-of-date the server now allows 'crippled' use.
* FTP response messages to clients now preserve case for file/path names.
* The "Too many users ..." message no longer shows the maximum number to clients.
* Try-out time has been changed from 30 to 45 days.
* Transfer speed reports use 1024 bytes per Kb rather than (previously) 1000.
* Added support for limiting the maximum bandwidth used by the server.
* The event EVNT_Login of the event notification mechanism now has
  the anonymous password in AuxOne (for anonymous users only).
* Fixed bug which would show a tray icon in NT4 even when the server was
  started 'hidden'.
* Minor changes to socket stack handing with the hopes that it will work with
  (even) more WinSock stacks.
* The SIZE command now works with either 'list' or 'read' access to the file.
  This used to require 'list' access.
* Fixed bug in SIZE command causing it to deny access if directory didn't
  have 'inherit' access.
* Data transfers now use a socket bound to the same IP as their command
  connection. This should fix a rare problem with multi-homed sites and
  firewalls.

Version 2.2 released 22 February 1997
-------------------------------------
* In case 'current' disk quota is set larger than 'maximum' uploads are no
  longer allowed.
* Changed the data connection message for uploads/downloads to be more UNIX
  compatible (some browsers use this to get the file size from).
* Serv-U now uses the native case for file/dir names, or optionally lower case.
* The ALLO (=allocate) command now handles 4Gb instead of 2Gb of free space.
* The security manager no longer checks for the presense of the SERV-U.INI file
  which hopefully solves a very rare problem where the server cannot read the
  .ini file after several days (in NT3.51 SP5).
* Added DLL interface for event notification and command hooks.
* In case no IP address can be found for the server it'll display "?????".
* Renaming directories works also now.
* Added support for IP names (with wildcards) in IP access rules.
* Added option to limit a user from logging in more than once from the same
  IP address.
* Fixed bug which prevented multi-homed IP numbers from showing in case no
  users were defined.

  conversion for new rule format.
* Added option to specify IP access rules for each user individually.
* Added tray icon support for Win95 and NT4.
* Changed code so 32-bit version can handle more IP homes (now it'll do around
  1800 IP numbers, while the 16-bit version handles about 180 IP numbers).
* Fixed bug in reporting of no. of try-out days left for the 32-bit version.
* LIST now completely ignores any '-' type options. NLST only parses '-l' and
  converts that to a LIST command. This should make the latest CuteFTP work.
* Fixed bug introduced in v2.1: Killed users that were put on the IP bounce
  list now work properly.
* Fixed bug introduced in v2.1: Putting the server in a directory path with
  spaces works now.
* Fixed bug in links introduced in v2.1 which caused crashes.
* Added support for running Serv-U as a system service in Win95.

-------------------------------------
* Fixed bug in 24h user count (sites with only a few hits a day would get
  bogus numbers).
* Added startup options /i (=iconic), /h (=hidden), and /u (=unconditional
  exit).
* When Serv-U was stopped while iconic it'll start as an icon the next time.
* The evaluation order of IP deny and allow rules can now be choosen.
* Fixed bug which would not allow dir listings if 'inherit' was not enabled
  and a dir listing with argument was done (ie. 'dir *.*').
* Changed link handling so if there is a subdir with the same name as a link
  preferance will be given to the subdir.
* Changed '%dfree' message file directive so it handles >2Gb of free space.
* All links should now be absolute paths, even for users with 'rel. paths'
  enabled. Serv-U takes care of the conversion for dir listings etc.
* Added support for the FTP command STAT, showing UL/DL ratios and quota.
* Changed %bup, %bdown, %btot, and %dfree to report in Kb instead of bytes.
* Added support for secundary 'dir change message file' and 'link file'.
* Added a very beautiful status bar.

* Added support for 'free files' for U/D ratios.
* Added feature to allow users to log in even when user limit is reached.
* User ID in log now always has 6 digits (with leading zeros if needed). To
  make programmatic sorting easier.

* Fixed bug causing GPF's while making server setup changes that resulted in
  a server restart.
* Added WinSock function logging.

* The '&' character in the registration key (if present) is now displayed
  correctly.

Version 2.0b, released 4 May 1996

  out of the homedir (and subdirs below), even if user has access rights for 
  other paths.
* Changed '~' handling. Now works when embedded inside a path.
* Fixed bug in 'Resume' command (FTP command 'REST').

------------------------------------
* Remote program execution (Through SITE EXEC) now launches the program from
  the current directory of the user.

  for an evironment variable named SERV-U, and finally the PATH and Window's
  directories are searched for the .ini file (Order changed over previous).\
* Added option to make server exit pending upon the logged in users.
* Fixed problem with window size/position when user info box got closed while
  minimized.
* Fixed problem with links containing trailing '\'.
* Fixed bug in '%dfree' text directive in 16-bit Serv-U.
* Added the FTP command REST (=RESTart).

  the Mac client 'Fetch').
* The permission server now uses UDP messages instead of TCP.
* Added support for user specific login messages.
* Changed font and size of signon/off message dialog box.
* Added support for 'links' (like UNIX).
* Fixed logscreen: It will now do automatic horizontal scrolling when the
  cursor is moved.
* User is now booted off the server if the password is guessed wrong 3 times.
* Time a user was connected gets logged.
* Inserting new paths in the access rule list is now done at current position
  instead of to the end of the list.
* 'CWD ' (='cd') or 'CWD ~' will now put the user back in the home directory.
* 'NLST *' (='ls') or 'LIST *' (='dir') will now convert to '*.*', ie. will
  use UNIX style globbing.
* Now even softer on your socket stack...
* Made the 'undocumented features' part of the setup.
* Changed directory listing format to be more UNIX compatible.
* Cleaned up local heap management, so the logwindow might actually work
  better.
* Added transfer speed to file transfer log messages.
* Fixed bug that caused filenames like '/c:' to be seen as relative.
* Changed all dialogboxes to use MS or Win95 3D-controls. No more BWCC.DLL.
* Data connection now uses the RFC959 default local port, ie. local port 20
  if the command connection uses 21. Should make some firewalls more happy.
* Added the FTP command SIZE. Should make Netscape happy (so it can tell
  filesize on transfer).
* Fixed client message in case 'anonymous' is disabled.

Version 1.1i
------------
* Change of address in all the documents.
* The try-out version will continu to work after October 15th. 1995 
  (v1.1h won't).
* Fixed bug in renaming long file names.
* Fixed bug that caused rare GPF's with some firewall proxy clients.

Version 1.1h
------------
* Added switch to explicitely disable long file/directory names in 
  Windows 95.
* Fixed a bug causing garbage to appear in some cases if a directory
  listing of an empty directory was made

Version 1.1g
------------
* Fixed bug in making directories for Win3.1 and WFW3.11.
* Fixed bug in deleting long file names under Win95.

Version 1.1f
------------
* Windows 95 long file names are supported. Serv-U auto-detects 
  the presence of Win95.
* The current number of users is displayed in the window title.
* The 'password' checks for anonymous users can be disabled.
* MS-DOS or Windows programs can be started remotely, using the 
  SITE command EXEC. The EXEC mechanism is also part of the 
  regular access rules.
* When the server is stopped while there are users logged in, a 
  dialogbox will pop up to confirm the action.
* Options to the LIST and NLST commands are handled (ie. 'ls 
  -la' like some clients send to the server will produce output).
* The FTP commands APPE (=append) and STOU (=store unique) are 
  now supported.
* Data type 'L8' (=local type 8 bits per byte) is now supported.
* Server is not restarted any more if maximum number of users 
  or time-out values are changed.
* The bug causing Serv-U to beep when it could not log to 
  screen has been fixed (actually a MS-Windows bug).
* Anonymous users no longer see hidden files.
* Drives are checked for accessability before usage, so no 
  longer the 'retry - ignore' dialogboxes.
* Info on the WinSock socket stack is shown on startup.
* Fixed bug causing false dir listings for 'dir .'.
* Made Serv-U more tolerant for firewalls using proxy servers 
  that mix PASV and PORT commands.
* Fixed bug that caused XCWD, XRMD, and XMKD to malfunction.

Version 1.1e
------------
* Anonymous users no longer see 'hidden' files.
* Fixed a rather nasty bug in the security system.
* Paths are now reported back with a leading '/'. This is to ensure 
  more compatibility with the UNIX format and to make a number of 
  Macintosh FTP clients even happier.
* The start-up message of Serv-U now reports the socket stack it is 
  running on.
* Fixed bug that assigned random passwords to users that should 
  have no password (a situation found in users belonging to a group
  where the group password should also be the user's password).
* When a user/group has a password it is now shown as '***********' in
  'setup - users/groups'. Deleting this deletes the password entry for 
  that user/group, ie. it no longer has a password. 
* Spaces are now allowed in user names and passwords.
* Stopping the server is logged (if logging to file is switched on).
* Paths are now consistently reported back using '/' instead of '\', to
  be more in line with the UNIX way of working. Mac FTP clients need 
  this to function properly.
* A leading '/' or '\' in front of a full pathname is ignored, ie.
  '/c:/util' is equivalent to 'c:\util'. This allows for UNIX style 
  changes of directory, and enables WWW browsers to change drives.
* The response to an incorrect anonymous password is changed to be 
  more informative.
* Very long pathnames are now supported correctly.
* Displaying a file when the client changes directory is supported.
* When 'setup - logging - FTP commands' is switched on it no longer shows
  passwords, 'XXXXX' instead.

Version 1.1, released 19 March 1995 
-----------------------------------
* Fixed some spelling errors in messages. Fixed logging to screen for
  time-out messages. Added log message in case limit of no. of users is
  reached. Added log message when server is (re)started. 
* Added lots of logging. 
* The SYST command now replies with the code for a UNIX system. This
  is because some clients use it to determine the format of directory 
  listings.
* Time-out values for idle/hung connections are now part of server setup. 
* Drastically increased packet time-out for data transfer, now set at 5
  minutes (was 30 seconds). Should be sufficient to allow transfer even on
  bad connections. 
* Log messages for failed data transfers now have a specification showing
  why. 
* Fixed bug that caused path for anonymous users with root as home
  directory to be reported without a '\' at beginning. The same bug caused
  absolute paths in CWD to be processed incorrectly. 
* Changed the HELP response to make WS_FTP work properly with
  Serv-U. 
* Added support for transfer to/from ports (PRN: AUX: LPTx: and
  COMx:). 
* Made a work-around for FTP Inc.'s WinSock stack. This stack does not
  handle SO_LINGER properly on closing a socket, causing 'data channel
  in use' errors. 
* Fixed bug that caused random truncation of PUT files in combination with
  some clients. 
* Fixed bug that allowed users to get 'dir' listings for paths with 
  explicitly no access set to them. 
* Fixed bug causing 'dir' with absolute path name to go wrong. 
  Changed response messages to file transfers, only the filename is shown
  now, not the path name. 
* Added a retry period for the server to come online. This should solve
  problems with socket stacks that do not allow to re-use a port
  immediately after closing it. 
* Changed the timing of the '150-' response message for PASV transfers. It
  is now sent after the data connection is established instead of at the 
  time of a transfer command. 
* The listening socket will now automatically be restarted when killed 
  by the socket stack. Some stacks kill listening sockets without reason
  (Trumpet for one). 
* Fixed a bug that made RMD (=remove directory) fail if the directory was
  on a drive other than the active drive. 
* Username 'FTP' is now synonymous to 'ANONYMOUS'. 
* Fixed bug in very long directory listings (>64K data). 
* Clients that connect but never log in are now kicked off the system 
  after 5 minutes. 
* User can now select the try-out method: Fully functional with contacts to
  my permission server, or, crippled but no permission server contacts. 
* Installed selectable path mechanism for anonymous: Either absolute paths
  (like a regular user) allowing for drive changes, or paths relative to the
  home directory (needed for WWW browsers). 
* Changed registration key to work with user/company name instead of IP
  number. Every time Serv-U is started it tries to read the key from a file
  KEY.TXT. Registered version displays the key in the "About" box and in
  reply to the FTP HELP command. 
* Changed the RETR and STOR replies (used for GET and PUT). They
  are now conform the average UNIX system. This makes WS_FTP more
  happy, so it shows a progress bar while downloading.

Version 1.00
------------
* Initial release 7 February 1995
