1. *** Introduction **************************************************

 VNC is a great and famous remote controle, multi-OS tool, created at
 the ATT Research Labs de Cambridge-http://www.uk.research.att.com/vnc

 This Ultr@VNC version is based on:
 - RealVNC 336 & 337
   and includes:
 - Most of eSVNC 1.1.2 r2 functionnalities
 - Most of Vdacc-VNC functionnalities
 - Cursor handling code and Tight encoding from TightVNC
 - VNC QuickDesk toolbar code
 - And various code modifications coming from talented developpers.

 - Since v1.0.0 RC 12, Ultr@VNC FileTransfer can transfer whole Directories.
   For this it uses "zip32.dll" and "unzip32.dll" dll files and source code
   coming from the Info-Zip group. Please see at the end of this
   document (section 7.) for details about these dlls.

 - Since v1.0.0 RC 12, the viewer Toolbar looks professionnal, thanks to
   Lim Chee Aun (http://www.phoenity.com/) who has designed it.

 Ultr@VNC brings tons of functionnalities and high performances even
 over modem connections.

 ------------------------------------------------------------------------
 Many thanks to all people who help us developping, testing, stabilizing,
 answering users questions and animating the mailing list.
 ------------------------------------------------------------------------



2. *** Features *****************************************************

* Supported Operating Systems: Win9x/Me/NT4/2000/XP/2003

* Auto configuration and Quick Options for easy connections.

* Viewer Toolbar for a quick access to the main functions and greatly
improved ergonomy.

* High Speed. On W2000 and XP, Ultr@VNC can use an additional and optionnal
Video Hook Driver (aka Mirror Driver) that dramatically improves performances
and reduces CPU activity over LAN connections. So when the bandwidth
is good - typically over a LAN - Ultr@VNC lets you work on a remote
computer with an incredible 'real-time' feeling (hundreds of screen
updates per second), just as if you were sitting in front of it. A
WinVNC server under Win9x uses the standard hookdll in combination
with ddi hooking to improve the updates
handling. Ultr@VNC also features an ultra fast Fullscreen Polling
mode without any additionnal driver.
Whatever the connection speed, Ultr@VNC brings you optimal comfort.
Note that this driver is distributed separatly from Ultr@VNC.

* Embedded File Transfer with intuitive Graphical User Interface allowing
for easy file copy between local and remote computers. It uses the current
VNC connection and files are compressed during their transfer.
File transfers can be asynchronous so screen updates can continue while 
a file is being transfered in background.
The delta transfer mode allows to resume interrupted transfers.

* MS Logon/NT security support. You can manage server access using MS Users,
Domains and Groups. It also includes a logging feature where all actions are
written to a log file.

* Bandwidth Saving Strategies that provide optimal responsiveness over slow
connections: Server Screen Scaling, Cache Management , Local Cursor handling,
reduced colors modes (256, 64, 8, Grey scales).

* Advanced JavaViewer featuring FileTransfer, MSLogon and reduced color modes.

* Data Stream Modification Plugin System allowing any kind of operation on the
data exchanged between client and server, from an external DLL (independant,
not linked and not distributed with Ultr@VNC): additionnal rights checking,
communication timing, data recording/persitence, encryption...
it's up to the DLL developper.

* Optionnal "always-on-top" Viewer Status Window dynamically displaying
connection informations.

* Various View Modes including Full-Screen, Scaled and Windowed. Full-Screen
mode lets you see the remote screen on the entire screen of your display.
Scaled Viewer mode lets you see the scaled remote screen in a window with a
user defined size. Scaled Server mode generates less network traffic from
server side and use a pixel blending algorithm to optimize the display.
Fuzzy Mode combines Server and Viewer scaling to provide reasonable visual
comfort and speed even over very slow connections.
The Autoscaling mode scales the view so it fits the viewer screen.

* Dynamic Single Window/Full Desktop view switching, from viewer side.
* Server's Desktop resolution switching without disconnection.
* Dynamic Mouse and Keyboard locking on remote server, from viewer side.
* Server Screen Blanking, from viewer side

* Embedded Client/Server Text Chat.

* Possibility to send Ctrl-Alt-Del to the remote server
(when WinVNC is run as a service), or any other special key.

* Support for 32/24/16/8 bits colors.
Both Ultr@VNC Viewer and Server are compatible with RealVNC, TightVNC, eSVNC,
PalmVNC2 (with server scaling feature)...
Ultr@VNC server can work as a Service under all supported operating systems,
allowing remote user Logon/Logoff as well as Remote Shutdown.

* Connectivity: Standard Viewer and HTTP JavaViewer connections over TCP/IP,
as well as XDMCP direct X11 connection (still experimental).

   - Viewer refresh after Texchat fixed
   - TextChat & FileTransfer windows can be redisplayed on the foreground
     when masked in Fullscreen mode by clicking on their corresponding buttons.
   - FileTransfer GUI double-click bug fixed

   - UltraVNC icon slightly changed
   - Toolbar tooltips now appear faster

   - Viewer "notoolbar" command line option replaces the stupid "showtoolbar"
     option...
   - WinVNC "connect" option fixed (works with host, host:display and host::port)
   - Fixed "quickoption" command line option bug in vncviewer

   - Added "Log Infos" and "Allow Loopback" options in WinVNC Property page.

   - UltraVNC is now compatible with PalmVNC2.0 even at the server screen 
     scaling level.   

   - Fixed Viewer crash when aborting connection
   - Remove Wallpaper after disconnection bug fixed
   - NTML mechanism now checks Local and Remote for Group and Password.
   - Fixed a bug with changes detection in WINVNC under W2K/WP: when the
     "Video Hook Driver" option was checked and the Video Driver was not
     actually available (not installed for instance...) then the default
     "System HookDll" was not loaded (even if the option was checked).
     The result was missing screen updates, especially with checkboxes,
     low accuracy and low speed. The workaround was to uncheck the
     "Video Hook Driver" option.

   - DSMplugin action now starts BEFORE the RFB protocole handshaking
     (-> 1.07 Viewer/Server DSM compatibility with 1.06 is broken
     but existing Plugins remain compatible with v1.07)
   - Info messages are now displayed when connection fails with DSMPlugin
     (Plugins incompatibility, missing etc...)
   - DSMPlugin now supports ms_logon method
   - Slightly modified TestPlugin sample
   - Added "dsmplugin" command line option in vncviewer

   - Video Driver handling:
     - Auto switching to default system hooking when 24bit color depth is used
       on server (the driver not used in this case)
     - 8bit color palette support
     - WinVNC keeps the attached-to-desktop bit to 1 until VNC unloads the
       driver -> No more crashes when an application changes the display
       (ex: pinball). No more risk that color depth or screen resolution
       switching crash the server.



** RC 1.08 (v1 Release Candidate 08)

   - The last major memory leak has been fixed in WinVNC

   - WinVNC occasionnal crash under NT4 during initial screen loading has been fixed

   - The CTRL,ALT,SHIFT keys locking bug has hopefully been fixed
 
   - The Viewer's authentication window has been renamed "VNC Authentication" instead
     of " Ultr@VNC Authentication" : now Ult@VNC Viewer is compatible again with
     the VNC-Quickdesk password transmission method...

   - Some additionnal tests have been added to prevent possible crashes:
     - "ms-logon + no domain + WinVNC under win 9.x" case
     - OS Version is better checked when Video Driver is required by user

   - Fixed the scaling factors corruption problem when using "AUTO" quickoption in 
     the viewer.

   - The DSM Plugins know their loader : vncviewer or WinVNC (application
     or service). It should be now more easy for plugins writters to save their plugins
     configuration at the good location in the registry, for instance.
     TestPlugin example source code has been updated consequently.

   terminating the viewer (->prevent a crash)

 - CTRL-ESC, Alt, CTRL, CTRL-ALT-DEL are now
   forbidden in ViewOnly mode

 - Viewer menu simplified and completed

 - Added Accelerator Keys (Hot Keys). They are
   displayed in the viewer's menu.
   (All are CTRL+ALT+Fxx keys)

 - Added AutoScaling : now the viewer window can be
   auto scaled/stretched so the server's screen is
   entirely visible (no scrollbars). The option is
   available along Quick options.

 - Viewer Scaling factors is now percentage in the
   Options window. More clear for users.

 - Hopefully fixed the screen refresh locking after a
   FileTransfer occasionnal bug.

 - Simplified Viewer TitleBar display (removed "VNC
   Viewer". Was useless and now we can directly see
   the hostname in the task bar).

 - Added hostname in the FileTransfer window Title bar.

 - Hopefully fixed the scaling crash that occurs in
   all others VNC distributions due to the StretchBlt()
   function + hardware acceleration.
   Visual quality remains equivalent when scaled.

 - Added a 30s delay between 2 encoding changes when
   using Auto mode. It should prevent some problems
   over slow connections...

 - Added ".vnc" load button in the "Connection" Dialog

     different ports numbers.
   - Pressing ALT or CTRL send ALT/CTRL directly to the VNCServer, as if the user selected "CTRL
     DOWN/CTRL UP/ALT DOWN/ALT UP" from the system menu.
     When turning the SCROLL-LOCK on, the following things happen:
     Pressing ALT+TAB DOES NOT switch applications on the client side. Instead, ALT+TAB is sent to
     the VNCServer. 
     Pressing CTRL+ESC DOES NOT open the start menu on the client side. Instead, CTRL+ESC is sent      to the VNCServer. 
     Pressing ALT+SPACE DOES NOT open the system menu on the client side. Instead, ALT+SPACE is      sent to the VNCServer. 
     Pressing Break/Pause key toggles Full-Screen mode on or off. 
     Pressing PRINT-Screen key requests a full screen update (same as selecting "Request Screen
     Refresh" from the system menu) 
     All the above can be disabled by turning the SCROLL-LOCK key off.
     (written by Assaf Gordon (Assaf@mazleg.com))



** v1.0.0 - RC 15 (v1 Release Candidate 15)

   - Tryout to make it stable again.
   - V15 is stable, but terribly slow when driver used

   - Driver handling was changed again.
   - It's stable and high speed is back.
   - Scrolling bug fixed, driver was giving invers delta
   - Driver screen moves and standard screen Moves detection can not be used together
     Both where cumulated--> delta x2
     Scrolling is handled by the driver, screen moves by the old method
   - Fixed sendmessage queuing problem.



** v1.0.0 - RC 17 (v1 Release Candidate 17)
DRIVER
-Driver consist of 2 parts, the actual mirror driver and a memory manager service.
-Final driver version

VIEWER/SERVER
-Fix cpu ghost issue on quiting viewer
-Fix connecing failed if screensaver+lock screen was running

** v1.0.0 - RC 18 (v1 Release Candidate 18 ) 
-Optimized RC17
-Code analysing to optimize performance
-Driver bug fixed
-smoother moves
-cache fix
-A lot of speed optimizations



** v1.0.0 - RC 19 (v1 Release Candidate 19)

 - Semi "Fast User switching support

  For each user session you switch to, a seperate winvnc server is started on the next port.
  User session A on 5900, after user switch, viewer get black.
  User session B on 5901 gets active, after switching back to session A,
  first user session viewer get back active

 - Shutdown

  Shutdown, vnc stops as last service. Needs to be tested,
  because vnc is not stopped at all, service breaks when network become unavailable.

 - Bug fixes

  Screensaver and lock screen caused server hung running as application, fixed
  logon blocks, and screensaver resolution changes are better handled.
  Plugin had a realy bad network behaviour, fast small updates like in
  "Starfield screensaver preview" could crash your network ....
  Manual update after logon/screensaver fixed
  Fixed blank screen and XP SP2
  Cancel button in vncviewer fixed (now it actually stop connection process)

 - Video Hook Driver mode

  Extra driver version check on startup 1.018/1.017/1.017 for driver files,
  else driver is disabled
  Extra driver check button in properties menu. Gives driver status

 - Performance

  Network traffic is send in 8k blocks (avoid flooding on wireless)
  Local mouse handling react faster on cursor change

 - System shutdown

  Viewer should now stay connected until you get the logoff screen

 - WinVNC Properties handling

  User settings (only poll settings, access for all users)
  Admin settings (all other critical settings, access for administrators only)
  In service mode, no user settings are used, excepted polling ones
  Only the primary session can open the Admin properties "FUS"

 - Multi-headed display (multi monitors support)

  Without Video Driver: user can toggle between primary or secundary display
  With Video Driver: switch toggle primary,secondary or both displays
  Selection is done using the "Full Desktop" Toolbar Button (which is normally used
  to toggle from Single Window to Desktop modes)
  "Server cursor handle", not supported if secundary screen is left (with driver)

 - Java Viewer

  Now supports FileTransfer (same kind of GUI than in win32 Viewer, but simpler...
  more functions will be added gradually (multiselection of files, directory transfer..)
   -> the JavaViewer now needs to access the viewing machine harddrive, so the user is
      prompted for an "UltraVNC" signed applet certificate acceptance.
  Support MS Logon authentication method

 - FileTransfer

  Now supports Delta Transfer for files (-> also provides Resume Interrupted transfer)
  Now transfers are asynchronous if wanted:
   When FT GUI is visible -> no screen updates, max speed for the transfer of files
   When FT GUI is minimized -> screen updates and file transfering at the same time
  Added multiselection for files deletion
  Added Rename File/Directory command
  Fixed some bugs with Directory Transfer (names with "(" or ")")
  Fixed huge files transfers and progress gauge corrupted display (> 2GB files)
  Added progress percentage value display
  A lot of code cleaning and sanity checks (both in Viewer and Server)
  New Viewer FilTransfer is still backward compatible with previous Servers (<=RC18)
  Directory Names are now surrounded with "[ " and " ]" in the GUI lists

 - MSlogon

 +toadd



** v1.0.0 - RC20 (.1, .2, .3)

- FileTransfer bugs seem all fixed this time. All the regressions due to the
  new asynchronous transfer mode + delta transfer should be solved.

- New FileTransfer Impersonation mode.
  Available only when WinVNC is run as a service.
  A user that connects to WinVNC and that is not yet identified by
  the server (Windows authentication, so he can see the Windows login screen)
  has no access to the server's filesystem through UltraVNC FileTransfer GUI.
  He must login into Windows first. Once identified, the user only has access
  to the filesystem resources allowed by his Windows profile.
  This mode can be desactivated by an admin if necessary:
    "FTUserImpersonation=0" in the WinVNC registry branch. In this case, the
    whole filesystem can be accessed by users, without restriction, like in
    previous UltraVNC FileTransfer versions.

- New color modes: 64 colors, 8 colors, 8 GreyScale, 4 GreyScale, 2 B&W

- The JavaViewer also supports the new color modes

- The WinVNC embedded HTML container for the JavaViewer now displays
  a warning saying that the Java VM must be installed on the Web Browser machine
  in order to get the JavaViewer working.

- Various small bugs fixes:
  - Forced X-cursor encoding sent to viewers: fixed
  - Bad minor version number sent causing Chat not supported (Server->Viewer): fixed
  - Command line ignored-options bug: fixed
  - NT4 Crash: fixed
  - DSM plugin mechanism: new Reset function added and bug fixed
    (note that versions of MSRC4 Plugins > 1.1.4 must now be used with RC20)
  - System resources and small memory leaks: fixed
  - Some registry settings bugs: fixed

- New "modern" dialog boxes look (XP)

- Slighlty redesigned and tweaked dialog boxes both in Vncviewer and WinVNC
  so they are more readable and look better.

- MSLogon II: lot of new features and bug fixes (see whatsnew.txt for details)

- Optional Alpha-Blending capture mode

- Optional Alpha-Blending screen-blanking mode (see whatsnew.txt for details)

- Last Viewer settings are automatically saved in a "latest.vnc" file in current
  users's "local settings" Win directory. So next time the user runs the viewer
  these settings are automatically reloaded.

- New single-http-connect port support. A separate WinVNC1P.exe is available
  and necessary to get this functionnality. This new fonctionnality will be
  included in the regular Ultra WinVNC as soon as possible.

- New Single-Click UltraVNC server. The Setup can be customized and generated
  online on the uvnc web site. Please see the Forum and Website for details.

 7. Details

 * How does Ultr@VNC use Info-Zip

   Ultra WinVNC and vncviewer both use 2 dlls for Directory Transfer:

   * Zip32.dll
   It is the original Info-Zip Zip 2.3 version (without encryption) that
   can be found on the Info-Zip sites, as well as its source code:
   http://www.info-zip.org/pub/infozip/
   http://www.cdrom.com/pub/infozip/
   ftp://ftp.info-zip.org/pub/infozip

   * Unzip32.dll
   Has been compiled using the portable unzip550 source code that can be
   found on the Info-Zip sites:
   http://www.info-zip.org/pub/infozip/
   http://www.cdrom.com/pub/infozip/
   ftp://ftp.info-zip.org/pub/infozip
   THE ONLY thing that was modified is that the "crypt.c" and "crypt.h"
   files have been replaced with the dummy (null) ones coming from the
   Zip 2.3 sources. So this unzip32.dll IS NOT the original Info-Zip
   "unzip32.dll" and does not contain any encryption/decryption code or binary.
