2.3a (October 7, 1997)
======================
- Fixed bug in NLST and LIST commands (for dir listing) which prevented the use of wildcards in dir listings.


2.3 (October 6, 1997)
=====================
+ REST (=resume command) now supported for file uploads.
+ Added support for the SITE INDEX command (only in the 32-bit version) as used by Fetch.
+ Changed path parser to recognize all possible ports and isolate them.
+ Added 'Register' menu to the help section. This allows users to generate a registration form on the fly and fill it out using NotePad.
+ Added new mechanism to enter a registration key into Serv-U, also added support for a new key format.
+ Added new message directives to keep track of server stats: Total up-time, total uploads and downloads (bytes/files), total users.
+ Changed internal string handling to improve performance.
+ 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.
+ 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.
+ The user info window can now be frozen for easier viewing.
+ The user info window can now be resized in height.
+ Passwords can now optionally be stored unencrypted. The default is that they get encrypted.
+ The 'kill user' dialogbox now allows editing of the IP address.
+ Renaming/moving a dir now requires 'remove' access to the path being 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.
+ 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.
+ Users with no password (ie. 'Password' entry in the .ini file explicitly set to nothing) are logged in immediately 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.
+ 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).
+ 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.
+ 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.
- Fixed bug in total file transfers count as shown in the status bar.
- 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.
- Fixed bug in system tray menu (Win95) when Serv-U gets started automatically after system startup.
- 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.
- Transfer speed reports use 1024 bytes per Kb rather than (previously) 1000.
- Fixed bug which would show a tray icon in NT4 even when the server was started 'hidden'.
- Fixed bug in SIZE command causing it to deny access if directory didn't have 'inherit' access.


2.2 (February 22, 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.
+ Added DLL interface for event notification and command hooks.
+ In case no IP address can be found for the server it'll display "?????".
+ 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.
+ Changed IP access rule mechanism. It is now more flexible. Added .ini file 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).
+ 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.
+ Added support for running Serv-U as a system service in Win95.
- 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).
- Renaming directories works also now.
- Fixed bug which prevented multi-homed IP numbers from showing in case no users were defined.
- Fixed bug in reporting of no. of try-out days left for the 32-bit version.
- 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.


2.1 (November 8, 1996)
======================
+ 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.
+ 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 a bunch of message file directives for ratios and disk quota.
+ Added disk quota limitation support.
