+ Added support for 'relative paths' for all users.
+ Added support for hiding 'hidden' files for every user.
+ Changed the max. no. of characters that can be entered into the multi-homed setup box for the IP number from 14 to 15.
- Fixed bug in 24h user count (sites with only a few hits a day would get bogus numbers).
- Fixed bug which would not allow dir listings if 'inherit' was not enabled and a dir listing with argument was done (ie. 'dir *.*').
- Fixed bug in 'restart' handling causing extraneous "450 Try later - Data connection in use" command error replies.

- Fixed bug causing GPF's for very long signon/signoff text lines.


2.0c (August 10, 1996)
======================
+ Added "%maxusers" and "%maxanonymous" directives.
+ Changed the implementation of the REST command ('resume') to be compatible with CuteFTP 1.5.
+ Added multi-homed IP support.
+ Changed dir listing format: Times before 10am now have a leading zero.  This to be more UNIX compatible and fix problems with WS_FTP.
+ More bullet proofing of the socket stack routines.
+ Added WinSock function logging.
+ Added support for external client verification DLLs. 
+ Bulletproofed the input buffer. It now handles any length strings.

- Fixed bug in MDTM command.
- Fixed problem in NT preventing directory deletion.
- Fixed bug causing GPF's while making server setup changes that resulted in a server restart.
- The '&' character in the registration key (if present) is now displayed correctly.


2.0b (May 4, 1996)
==================
+ Bullet-proofed the 'relative paths anonymous' option. Now impossible to get 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').
- Changed code for painting text & images in 'About' box, hopefully solving problems on Win3.1 and WFW3.11.


2.0a (April 18, 1996)
=====================
+ Remote program execution (Through SITE EXEC) now launches the program from the current directory of the user.
+ The Serv-U directory is now searched first for SERV-U.INI, then it looks 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.
+ Added the FTP command REST (=RESTart).
+ Changing the file name for directory change messages no longer causes the server to log out all users.
+ Added the FTP command MDTM (=Modification Date & TiMe).
+ Hidden directories are now hidden from anonymous users (as are hidden files) in the 32-bit version.
+ Transfer speed in 'User Info' box is now averaged.
+ Links embedded in a path will now be resolved correctly. This will make things work better with Netscape which keeps links as part of the path.

+ Added file size to transfer logs.
- 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.
- Fixed bug in DNS lookups that caused GPF's.
- Background colors of bitmaps (in 'About' etc.) now display correctly on non-gray windows.
- Fixed error reply for 'SITE EXEC' in case no executable was specified.
- Fixed bug that caused 'File - Exit' to skip the confirm dialogbox.
- Fixed bug in '~' handling. It can now be used in links.
- In case CTL3DV2.DLL is missing the 16-bit version will no longer throw an exception.


2.0 (March 13, 1996)
====================
+ This version will continue to work after March 15th (All previous versions stop at that date).
+ Converted code to BC 4.52 and OWL 2.5. 
+ Now 16- and 32-bit versions.
+ Added separate access right for 'list' access.
+ Added a luxurious 'user info' box.
+ Added IP Name logging.
+ Added a 'enable account' checkbox to quickly enable/disable a user.
+ Access rules can now be specific to a single directory, or inhereted by subdirs (the previous method).
+ Changed the FTP 'HELP' command reply to be more UNIX compatible.
+ Added a ton of new '%' directives for signon/signoff messages, directory change messages, and login messages.
+ Changed icons.
+ 'hidden' files are no longer indicated as such in dir listings (confused 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).
+ 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.
+ 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.
- Fixed various dialogbox errors (text, formatting).
- Non-anonymous users can now also delete 'read only' files.
- Fixed logscreen: It will now do automatic horizontal scrolling when the cursor is moved.
- Fixed bug that caused filenames like '/c:' to be seen as relative.


1.1i (September 18, 1995)
=========================
+ Change of address in all the documents.
+ The try-out version will continue 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.


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


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


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.
+ 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.
+ Made Serv-U more tolerant for firewalls using proxy servers that mix PASV and PORT commands.
- The bug causing Serv-U to beep when it could not log to screen has been fixed (actually a MS-Windows bug).
- Fixed bug causing false dir listings for 'dir .'.
- Fixed bug that caused XCWD, XRMD, and XMKD to malfunction.


1.1e
====
+ Anonymous users no longer see 'hidden' files.
+ 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.
+ 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.
+ 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.
- Fixed a rather nasty bug in the security system.
- 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).
- Very long pathnames are now supported correctly.


1.1 (March 19, 1995)
====================
+ 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. 
+ 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. 
+ 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). 
+ Username 'FTP' is now synonymous to 'ANONYMOUS'. 
+ 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.
- 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. 
- 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. 
- 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. 
- Fixed a bug that made RMD (=remove directory) fail if the directory was on a drive other than the active drive. 
- Fixed bug in very long directory listings (>64K data). 


1.0 (February 7, 1995)
======================
* Initial release.
