1 +--------------------------------------------------------------------+
2 | This is a brief summary of changes introduced in each TightVNC |
3 | release. For more details, please see ChangeLog files included |
4 | in TightVNC source and binary archives. |
5 +--------------------------------------------------------------------+
9 - All platforms: Added support for the standard RFB protocol version
10 3.8 with TightVNC extensions.
12 - All platforms: Made "host:port" parsing maximally compatible with
13 VNC4. Interpreting a number in host names like somehost:5900 as an
14 actual port number if it's not in the range [0..99].
16 - Windows Server: Various user interface enhancements - changes in
17 GUI labels, tray icon with a red border when incoming connections
18 are not possible for any reason, more information in the tray icon
19 tip, smarter logic in displaying the Properties dialog, and more.
21 - Windows Server: Fixed a problem introduced in TightVNC 1.3.8 -
22 default passwords were not respected if user passwords were not
25 - Windows Server: Slightly improved handling of passwords. One of
26 the notable changes is that now it's enough to enter a view-only
27 password without providing primary password.
29 - Windows Server: Fixed problems with running WinVNC service and
30 Terminal Services. When a Remote Desktop (RDP) client connected to
31 the console, WinVNC showed black screen and did not restore normal
32 operations even on disconnection of that RDP client. Now, we
33 always share the console correctly, and disable simultaneous RDP
34 and VNC sessions. The changes were ported from VNC 4.1.2.
36 - Windows Server: Better way of simulating Ctrl+Alt+Del. There are
37 reports that this solves the problem with greyed username and
38 password fields on Windows 2003 Server (bug #887617).
40 - Windows Server: Bugfix for the bug #1109102: attempt to restart
41 the machine remotely via TightVNC led to disconnect if there was
42 some non-saved data, and further connections were rejected.
44 - Windows Viewer: Multiple selection now works in file transfers,
45 thanks to developers at Novell and personally Rohit Kumar.
47 - Windows Viewer: The viewer terminated silently when the server
48 dropped connection right after accepting it. Now we report such
51 - Windows version source archive: Included project files for
52 compiling with Visual C++ 2005 Express Edition. Also, all required
53 libraries are now included within the source distribution.
55 - Unix Server: Applied patches from Debian Linux that port Xvnc to
56 x86_64 platform (tightvnc-1.2.9-amd64support.p and
57 tightvnc-1.3_alpha7-x86_64.patch), thanks to Quanah Gibson-Mount.
59 - Java viewer: Implemented scaling, either with a fixed scaling
60 factor or automatic. If Java 2D API is available (Java 1.2 and
61 higher), then high-quality scaling is used. From the other side,
62 the viewer remains compatible with Java 1.1 where it would simply
63 use scaling with much decreased image quality. Scaling can be
64 enabled with new "Scaling Factor" parameter but cannot be
65 controlled from the GUI yet.
67 - Java viewer: Added support for ZRLE encoding.
69 - Java viewer: Disabled focus traversal keys under JVMs 1.4 and
70 higher. This fixes the problem with not sending Tab key events to
73 - Java viewer: Fixed wrong pixel format interpretation at decoding
74 RichCursor pseudo-encoding (local cursor could be rendered in
77 - Other improvements and bugfixes, see ChangeLog files within the
78 distribution for more details.
80 * TightVNC 1.3.8, release candidate version
82 - Win32 server: Fixed major problem with disconnecting clients on
83 screen locking, user logoff and logon, in the service mode.
85 - Win32 server: Added support for DFMirage driver direct screen
86 access mode (from DemoForge LLC).
88 - Win32 server: Added support for multiple monitors (from DemoForge
91 - Win32 server: Improved layout and functionality of the Properties
94 - Win32 server: More accurate password handling - now the server
95 code tries to distinguish between "empty" and "unset" passwords
98 - Win32 server: New -shareall, -shareprimary and -sharearea
99 command-line options, working similarly to the -sharewindow
102 - Win32 server: Fixed problems with restoring desktop wallpaper.
104 - Win32 viewer: Fixed bug with not enabling JPEG compression by
107 - Win32 viewer: Fixed bug with not setting proper size of the viewer
110 - Unix server: Port numbers are now calculated modulo 65536 with
111 vncviewer's -listen option. That makes it possible to listen on
112 TCP ports under 5900.
114 - Java viewer: Automatic encoding selection based on measuring
115 current network throughput.
117 - Other improvements and bugfixes, see ChangeLog files within the
118 distribution for more details.
120 * TightVNC 1.3dev7, release candidate version
122 - Win32 server: Fixed the problem with "olemainthreadwndname not
123 responding" in service mode under Windows NT 4.0. Under that OS,
124 the TightVNC service could hang on logoff.
126 - Win32 server: Removed the code for "desktop optimizations" that
127 was rather harmful than useful. Hopefully, this should fix
128 problems with crashing Delphi applications. Also this should
129 prevent settings like font smoothing always set to true on
132 - Win32 server: Fixed the issue with port number edit boxes that
133 were labeled incorrectly in the Properties dialog.
135 - Win32 server: Disallowing clipboard transfers in view-only mode.
137 - Win32 server: Fixed the problem with carriage return/linefeed
138 conversion of clipboard data.
140 - Win32 server: Fixed the problem with wallpaper being removed only
141 after completing the initial screen transmission.
143 - Win32 server: Minor improvements in the File Transfers dialog.
145 - Win32 server: More context help messages in Properties and File
148 - Unix server: Fixed a serious bug with sending cursor updates when
149 there was no FrameBufferUpdateRequest from that client.
151 - Unix server: Fixed problems with building Xvnc on modern linux
152 distributions, such as Fedora Core 3.
154 - Unix server: Disallowing clipboard transfers for view-only
157 - Other improvements and bugfixes, see ChangeLog files within the
158 distribution for more details.
160 * TightVNC 1.3dev6, Win32 release candidate version
162 - Win32 server: Improved layout of the Properties dialog, added
163 context help for every option. Also, current mirror driver status
164 is shown in the Hooks tab.
166 - Win32 server: Implemented new checkbox "Enable applet params in
167 URLs" corresponding to EnableURLParams registry setting.
169 - Win32 server: The option "Don't use mirror display driver even if
170 available" is now functional.
172 - Win32 server: New option "Blank screen on client connections".
173 When set and new client connects, the server's monitor is forced
174 to go to power saving mode.
176 - Win32 server: Fixed bugs with saving certain settings in the
177 registry, and bugs with setting default values when the registry
180 - Win32 server: Fixed a problem with one-pixel mouse offset.
182 - Win32 server: Fixed problems with inter-thread locking, this
183 should solve "Unhandled message type received" problems.
185 - Win32 server: Fixed a problem with the setting "Block remote input
186 on local activity", it was not working with DLL hooks disabled.
188 - Win32 server: Fixed various problems with file transfer
189 implementation. Error handling was improved, the C: drive bug
190 under Win98/Me seems to be solved.
192 - Win32 viewer: New "Auto" scaling mode. In this mode, the viewer
193 scales remote desktop to fit local window or screen size. If the
194 window size is changed, the scaling factor is adjusted
197 - Win32 viewer: Now the viewer checks server's capabilities and does
198 not ever use non-standard protocol messages not supported by the
199 server. This change affects file transfers only, as other features
200 do not use non-standard protocol messages..
202 - Java viewer: New "scale remote cursor" option has been added. It
203 allows to reduce or enlarge cursor image in the full-control mode.
205 - Java viewer: A cursor repaint problem has been fixed.
207 - Other improvements and bugfixes, see ChangeLog files within the
208 distribution for more details.
210 * TightVNC 1.3dev5, development version
212 - Win32 server: Support for the "DFMirage" mirror video driver has
213 been added (the driver itself will be available separately). Using
214 the mirror driver greatly increases the speed and reliability of
215 updates, and also desreases CPU utilization on the server.
217 - Win32 server: New polling algorithm has been implemented. It's
218 similar to that found in x0rfbserver. New algorithm uses minimum
219 CPU time when there are no changes on the screen, and detects
220 major changes very quickly, resulting in greatly improved
221 responsiveness on the client side.
223 - Win32 server: Improved methods for filtering screen changes that
224 actually do not change anything. New algorithm not only works
225 faster, but it also detects changes much more accurately, leaving
226 less work to encoders.
228 - Win32 viewer: A special mode for Unix users has been implemented:
229 when ScrollLock is on, the viewer will send Meta on pressing Alt
232 - Win32 server: Fixed a problem with view-only clients that were
233 enabled full control on just opening the Properties dialog of the
236 - Win32 server: It should not ever hang any more on changing ports
237 or the LoopbackOnly setting.
239 - Win32 server: DisableTrayIcon and RemoveWallpaper settings are
242 - Win32 server: The problem with not saving Query Settings has been
245 - Win32 server: The polling mode "on event received only" has been
246 fixed - it did not work correctly in previous version.
248 - Win32 server: Fixed a number of issues with mouse handling,
249 including that annoying problem with pointer jumping on slow
252 - Win32 server: Applied a bugfix from HorizonLive solving the
253 problem with crashes or incorrect operation after color depth
254 changes on the server's desktop.
256 - Win32 viewer: It does not crash any more on entering long
257 passwords in the authentication window.
259 - Win32 viewer: Positioning and resizing logic of the viewer window
262 - Win32 viewer: Now the viewer chooses more reasonable file names
263 for saved .vnc sessions.
265 - Win32 viewer: In the full-screen mode, the viewer allows other
266 windows to be shown above the remote desktop. This makes hotkeys
267 such as Shift-Ctrl-Alt-O useful in the full-screen mode.
269 - Unix version: A number of bugfixes -- copying clipboard to
270 non-authenticated clients in Xvnc, delayed cursor shape updates in
271 Xvnc, and crashing on switching between KDE virtual desktops in
274 - Unix viewer: Support for the new -autopass option has been added,
275 a patch from Ki NETWORKS, Inc.
277 - Other changes, see ChangeLog files within the distribution for
280 * TightVNC 1.3dev4, development version
282 - Featuring updated Unix version and Java viewer, supporting RFB
283 protocol version 3.7, with or without TightVNC protocol
284 extensions. Version 3.3 of the protocol is supported as well.
286 - Win32 version: Built-in Java viewer was absent in the previous
287 development version; now it's available again.
289 - Win32 version: Now the server does not crash on remote
290 Ctrl-Alt-Del events, and on changing display modes.
292 - Win32 version: A problem with reinstalling the service has been
293 fixed (WinVNC -reinstall command-line option). In previous
294 versions, reinstalling the service could fail if a user did not
295 close "Service unregistered" message box within a few seconds.
297 - Win32 version: Now the server does not hang on selecting equal RFB
298 and HTTP port numbers. A warning is shown instead.
300 - Win32 version: The server does not hang on toggling loopback
301 connection options, and on changing port/display numbers.
303 - Win32 version: WinVNC does not crash on choosing "Kill All
304 Clients" during file download.
306 - Win32 version: CopyRect handling in the server has been fixed, the
307 CopyRect encoding is enabled again.
309 - Win32 version: The Advanced Properties dialog of the server has
310 been removed. The controls of that dialog has been moved to tabs
311 in the Properties dialog.
313 - Win32 version: Context help in the server's Properties dialog has
314 been implemented (although not all descriptions are ready yet).
316 - Unix viewer: Fixed a bug with the viewer crashing on selecting
317 text in Xvnc, and then choosing F8 / Clipboard: local -> remote,
320 - There was some progress on supporting pluggable encryption and
321 authentication methods, in both Win32 and Unix versions, and in
324 - Other changes, see ChangeLog files within the distribution for
327 ----------------------------------------------------------------------
329 * TightVNC 1.3dev3, Win32 development (unstable) version
331 - All features and fixes from 1.2.9 and 1.3dev1 versions included.
333 - Improved GUI of the viewer featuring toolbar, hotkeys, pre-set
334 connection profiles, more configuration options, context help in
335 dialogs, and more. Finally, the viewer remembers all
336 per-connection and global settings in the registry.
338 - File transfers between viewer and server machines.
340 - Support for RFB protocol version 3.7, with TightVNC extensions.
342 - A possibility to turn off hooking via VNCHooks.dll in WinVNC while
343 full screen polling is in use.
345 - Other changes, see ChangeLog files within the distribution for
348 ----------------------------------------------------------------------
352 - Win32 version: Major security-related bug in the server has been
353 fixed -- handling of the "QueryAllowNoPass" option was seriously
354 broken. Together with fixing this bug, the whole authentication
355 logic in the server code has been redesigned.
357 - Win32 version: Now the HKEY_CURRENT_USER registry hive is being
358 closed properly on restoring display settings, on disconnect. This
359 change should solve the problem with unloading the registry on
360 logout, when WinVNC is running as a service.
362 - Win32 version: Problems with "QuerySetting" and "QueryTimeout"
363 options have been fixed -- the settings could be copied from user
364 configuration to default settings without user's intention.
366 - Win32 version: A long-standing bug has been fixed -- the logic to
367 handle retries after authentication failures was flawed, and used
368 to delete the same object twice under certain conditions.
370 - Win32 version: Now it's possible to specify port numbers with the
371 winvnc -connect option, using the "host::port" format. Also,
372 providing a -connect option without arguments now brings up the
373 "Add New Client" dialog.
375 - Unix version: New "Request refresh" button has been implemented in
376 the viewer's F8 popup menu.
378 - Unix version: Xvnc compilation fixes for HP-UX and MacOS X have
379 been applied, from Ki NETWORKS, Inc.
381 - Unix version: New vncpasswd -f command-line option has been
382 implemented. It allows providing passwords on stdin and writes
383 encrypted passwords to stdout. In addition, the password file name
384 "-" now denotes stdout. Finally, a buffer overflow has been fixed
385 in vncpasswd -- it could be caused by a long file name in the
388 - Unix version: A patch to fix input focus problems in the X11
389 viewer has been applied, from Greg Breland.
391 - Unix version: A patch fixing Xvnc crashes on Sparc has been
392 applied, from the RealVNC distribution.
394 - Unix version: A problem with incorrect port interpretation has
395 been fixed, in the vncviewer's -tunnel option handling. Thanks to
398 - Java viewer: A modification from Bernd Krueger-Knauber has been
399 accepted, to pass through X keysyms for foreign currencies.
401 - Java viewer: The problem with initial keyboard focus not set to
402 the desktop on some JVMs has been fixed.
404 - Other minor improvements and bugfixes.
406 ----------------------------------------------------------------------
410 - Unix and Win32 versions: Support for a separate view-only password
411 has been implemented. Now the servers support two passwords -- one
412 to allow full control, another to restrict remote keyboard and
415 - Win32 version: The password reset problem has been solved. In
416 versions starting from 1.2.4, the password could get changed in
417 the registry on opening Properties dialog and just hitting the OK
420 - Win32 version: New "-reload" command-line option has been
421 implemented in Win32 server. It forces the running instance to
422 reload the registry settings.
424 - Win32 version: "RemoveWallpaper" and "LockSetting" options have
425 been made configurable in the Properties dialog; the code has been
426 ported from RealVNC 3.3.6.
428 - Win32 version: Support for "AllowEditClients" registry setting has
429 been ported from RealVNC 3.3.6.
431 - Unix version: New "-x11cursor" option has been implemented in
432 vncviewer; a patch from Peter Astrand. This option allows using a
433 real X11 cursor with X11-style cursor shape updates, disables the
434 dot cursor, and disables cursor position updates in non-fullscreen
437 - Unix version: New "RunCommand" command to customize the X11
438 vncviewer popup menu has been implemented; a patch from Peter
441 - Unix version: Several patches from Debian Linux have been applied.
442 This should fix a number of bugs and improve building on some
443 platforms supported by Debian Linux.
445 - Unix version: A problem with Xvnc eating all CPU time after xfs
446 restarts has been fixed; a patch from Martin Koegler.
448 - Other minor improvements and bugfixes.
450 ----------------------------------------------------------------------
454 - Unix and Win32 versions, Java viewer: The most significant problem
455 with local cursor handling has been solved -- now clients can see
456 remote cursor movements performed on the server or by another
457 client. New PointerPos encoding and cursor shape updates both
458 minimize bandwidth requirements and greatly improve responsiveness
459 of the mouse pointer, while still allow to track correct pointer
460 position in all situations.
462 - Unix and Win32 versions: In all the places where display numbers
463 had to be used, now it's easy to use port numbers as well. The
464 viewers now allow to use new "hostname::port" syntax, in addition
465 to the traditional "hostname:display" format. The same new syntax
466 can be used in the "Add new client" dialog of Win32 server. In the
467 server, now it's equally easy to set display and port numbers.
468 Besides that, HTTP and RFB port numbers can be set individually.
470 - Unix and Win32 versions: In servers, decreased JPEG quality
471 factors for low quality levels. This improves bandwidth usage
472 while the image quality remains satisfactory in most cases. In
473 clients, JPEG compression is now enabled by default, because
474 usually it's a reasonable choice. To prevent viewers from
475 requesting JPEG compression, new -nojpeg option can be used.
477 - Unix and Win32 versions: Improved installer under Windows, better
480 - Win32 version: Major enhancements in layout and functionality of
483 - Win32 version: New keyboard handling code has been ported from
484 RealVNC 3.3.6. This should solve all the issues with arrow keys
485 acting as numbers in console windows, and shift+arrows not working
488 - Win32 version: Adopted WinVNC -reinstall option from RealVNC
489 3.3.5, together with a number of other changes in different
490 places. The viewer now accepts a port number after the -listen
491 command-line option, an improvement from RealVNC 3.3.6.
493 - Win32 version: Eliminated high CPU usage on the server before
494 sending cursor shape updates.
496 - Unix version: Bugfix for Xvnc's -localhost and -interface options
497 that were broken on many systems, thanks to Luke Mewburn for the
498 bugfix. Xvnc -version command-line option is now supported.
500 - Tight encoding is now documented in rfbproto.h files within source
503 - Java viewer: Implemented new buttons "Login again" and "Close
504 window" near the disconnect or error messages in the applet mode,
505 and introduced new "Offer Relogin" parameter to control this
506 improvement. Thanks to Peter Astrand for the initial version of
507 the "Login again" patch.
509 - Java viewer: Support for connections via HTTP proxies using HTTP
510 CONNECT method. This will not work in the applet mode, due to Java
511 security restrictions.
513 - Java viewer: Extra .vnc files have been removed, having just
514 index.vnc should be enough. Also, an example HTML page has been
515 prepared, to simplify installation under a standalone Web server.
517 - Java viewer: Added a MANIFEST to the JAR archive, to allow easy
518 execution of the JAR file, using java -jar command-line option.
520 - Other minor improvements and bugfixes.
522 ----------------------------------------------------------------------
524 * TightVNC 1.3dev1, Win32 development (unstable) version
526 - Implemented partial screen sharing. Any single window or any
527 rectangular screen area can be shared instead of the whole screen.
528 The position and dimensions of the shared screen area can be
529 changed dynamically, and client windows will adjust their
530 dimensions on the fly. The user interface to choose shared screen
531 area is very intuitive and easy to use.
533 - Screen resolution changes won't cause WinVNC to disconnect clients
534 any more (but changes in screen color format still result in
535 disconnects, this will be fixed later).
537 - It's possible to make WinVNC ignore remote inputs when local mouse
538 or keyboard is in use. Remote events will be re-enabled after a
539 specified timeout (3 seconds by default).
541 - There may be other changes I forgot to mention. :-)
543 ----------------------------------------------------------------------
547 - Win32 version: In this version, when WinVNC binds to a local TCP
548 port, it does not try to check several times if the port is in
549 use. It just re-uses the port if the display number is not set to
550 "Auto". One visible effect of this change is that the delay
551 between starting up and showing the icon is greatly reduced.
553 - Unix version: Fixed the bug which caused the vncserver script to
554 fail when the XAUTHORITY environment variable was not set.
556 - Unix version: Fixed the bug which prevented the vncpasswd utility
557 from setting correct permissons on the passwd file.
559 - Unix version: Fixed a repeated challenge replay attack
560 vulnerability, bugtraq id 5296.
562 - Unix version: Added files to simplify building of Linux RPMs,
563 thanks to Peter Astrand.
565 - Unix version: Improved scrolling in the full-screen mode, modified
566 patch from Ville Herva.
570 ----------------------------------------------------------------------
574 - Win32 version: Fixed a problem in the I/O subsystem that was
575 introduced in TightVNC 1.2.2 and was causing major slowdown in
576 communication with clients.
578 - Win32 version: Enabled remote upgrade in the installation script.
579 Also, the installer will install a copy of the TightVNC Web site,
580 and will create shortcuts to most important documentation pages.
582 - Win32 version: Implemented new feature to specify applet
583 parameters in URL requests being sent to the built-in HTTP server.
584 Added support for new "EnableURLParams" registry setting which can
585 be used to enable this feature.
587 - Win32 version: Added support for the NewFBSize pseudo-encoding
588 allowing to change framebuffer geometry on the fly on server's
591 - Win32 version: Included "solution" and "project" files for MS
592 Visual Studio 7, from Andrew van der Stock, applied a set of minor
593 fixes to suppress compilation warnings under MS Visual Studio 7.
595 - Win32 version: The viewer now tries to preserve the size and
596 position of the desktop window after applying new connection
599 - Unix version: Implemented new feature to specify applet parameters
600 in URL requests being sent to the built-in HTTP server. Added
601 support for new $PARAMS variable in .vnc HTML templates.
603 - Unix version: Added the possibility to keep users' vnc directories
604 under /tmp, as suggested by Ivan Popov. This mode can be enabled
605 by editing the $vncUserDir variable in the vncserver script. Also,
606 new -t option has been implemented in the vncpasswd utility which
607 allows to change VNC password files under /tmp.
609 - Unix version: Applied Xvnc -viewonly patch from Ehud Karni.
611 - Unix version: Applied Linux/PowerPC Xvnc fix from Peter A. Castro.
613 - Unix version: Bug fixed: Xvnc failed to reset compression level
614 and JPEG image quality on reading lists of encodings supported by
617 - Unix version: Made the viewer handle XCursor encoding operating on
618 the framebuffer instead of setting new cursors directly in X.
620 - Unix version: Applied a number of porting fixes from Ki Networks,
623 - Java viewer: Added new feature allowing to save RFB sessions in
624 FBS files compatible with rfbproxy. This feature works only if JVM
625 security manager allows access to the local filesystem, which is
626 usually true only when the viewer is used as a standalone
627 application or if the viewer applet is cryptographically signed.
628 New "Record" button will appear in the button panel if this
631 - Java viewer: Added new "ENCPASSWORD" parameter, modified patch
634 - Java viewer: Applied patch from Peter Astrand to fix problems with
635 Swedish keys and broken JVMs.
637 - Other minor fixes and cleanups.
639 ----------------------------------------------------------------------
643 - Win32 version: WinVNC crashes on reporting zero statistics were
644 fixed. This should eliminate crashes when using x2vnc and win2vnc
647 - Win32 version: a problem with listening viewer was fixed.
648 Initiating multiple non-shared connections could crash the viewer
651 - Win32 version: real passwords are never placed into the password
652 text control in the WinVNC Properties dialog any more. This should
653 prevent grabbing plain-text passwords from that text control.
655 - Win32 version: logging on errors was improved to provide better
656 diagnosis for errors, especially for those causing the message
657 "Connection closed" right after authentication.
659 - Win32 version: handling of log files was improved. Now WinVNC
660 should be able to save backup copies of log files under
661 Win95/98/Me. Also, all log files are now written in MS-DOS/Windows
662 text format instead of the Unix one.
664 - Win32 version: a problem with reporting error messages in the
665 listening viewer was fixed.
667 - Win32 version: reporting incorrect statistics in the Tight encoder
670 - Win32 version: HTML pages and templates for the built-in HTTP
671 server were improved.
673 - Unix version: applied patch from Ki Networks, Inc. solving build
674 problems on a number of commercial Unix systems, and fixing a
675 number of minor bugs and typos.
677 - Unix version: added a possibility to denote standard input with
678 the "-" file name instead of a real password file name.
680 - Unix version: fixed a bug causing vncpasswd utility work
681 incorrectly when a file name argument was given in the command
684 - Unix version: applied patch to solve keyboard focus problems in
685 the full-screen vncviewer, from Peter Astrand. The patch does not
686 seem to solve all the issues, but definitely makes things better.
687 New grabKeyboard resource was added to control full-screen mode
690 - Java viewer: new "Show Offline Desktop" parameter was added to
691 make the desktop still visible even after the remote side has
694 - Java viewer: error messages were made much more meaningful.
696 - Java viewer: keyboard focus problems were fixed. This should
697 prevent opening new windows (e.g. Options or Clipboard) behind the
698 active authenticator or desktop window.
700 - Java viewer: now "R"/"r" keys can be used to request screen
701 updates in view-only mode.
703 - Java viewer: applied patch from Peter Astrand to fix problems with
704 Swedish keys and broken JVMs.
706 - Other minor fixes and cleanups.
708 ----------------------------------------------------------------------
712 - Unix and Win32 versions: zlib library was updated to the most
713 recent version (1.1.4) where a potential security issue was fixed.
715 - Unix and Win32 versions: fixed blocking I/O problems in built-in
716 HTTP servers. Older versions had to wait while one client finishes
717 his transaction, only then they served new client connections,
718 thus making easy denial-of-service attacks possible.
720 - Unix and Win32 versions: updated built-in Java viewer, see details
723 - Win32 version: Added support for mouse wheel events. Wheel mouse
724 support is fully compatible and interoperable with Unix version
725 where this feature was available for a long time.
727 - Win32 version (WinVNC): The -connect command-line option now
728 accepts a display number after a hostname.
730 - Win32 version: Creating associations for .vnc files in the
733 - Java viewer was GREATLY improved: the code was converted to Java
734 1.1, painting techniques were re-designed completely (now the
735 viewer should work in MacOS), several new parameters were added,
736 all parameters were documented in the README file. Most important
737 new features include: support for 24-bit colors, JPEG support in
738 Tight encoding, RFB Bell message support, new "Refresh" button, a
739 possibility to operate in a separate scrollable window, dynamic
740 view-only mode. Many more changes were introduces, see the
741 ChangeLog for more information. Please note that new Java viewer
742 class names were changed, e.g. vncviewer.jar file has become
745 - Unix version: a number of changes in the vncserver script, e.g.
746 the default color depth is now 24, extra delay after Xvnc startup
747 removed, font path is now configurable in the beginning of the
750 - Unix version: zlib library was removed from the core X sources.
751 Instead, both vncviewer and Xvnc now can use either system zlib
752 and JPEG libraries, or ones packaged within TightVNC source
753 archive in the lib/ directory. Unix sources are distributed in two
754 versions: one with these libraries for those who don't have them
755 installed in the system, and another version without libraries,
756 copied directly from CVS, for those who do have zlib and/or JPEG
757 libraries installed. In the former case, build procedure would
758 include additional "make libs" step. System libraries will be
759 linked dynamically, libraries included in the source archive will
760 be linked in statically.
762 - Unix version now includes comprehensive manual pages for
763 vncviewer, vncserver, Xvnc, vncconnect and vncpasswd programs. The
764 vncinstall script in the source distribution now accepts one more
765 parameter allowing to specify where to install manual pages.
767 - Unix version (Xvnc): a number of patches from Red Hat Linux vnc
768 package were incorporated into the TightVNC codebase. This adds
769 support for more architectures including s390 and s390x, adds a
770 possibility to use tcp_wrappers for Xvnc access control.
772 - Unix version (Xvnc): several bugfixes, e.g. applied patch to fix
773 crash in the code dealing with font server; fixed word alignment
774 problem in raw encoder experienced by Sparc users.
776 - Unix version is no more distributed as patches to a standard VNC
777 release. This is because patches cannot handle changes in binary
778 files and handle file removals very inefficiently.
780 - Other minor fixes and cleanups.
782 ----------------------------------------------------------------------
786 - Win32 server: long-standing Win9x resource consumption problem has
787 been fixed. Now the server thread does not use blocking I/O, and
788 therefore is always ready to process messages from the VNCHooks
791 - Win32 server: now built-in HTTP daemon may be enabled and disabled
792 interactively from the Advanced Preferences dialog (this setting
793 is saved in new "EnableHTTPDaemon" registry key).
795 - Win32 server: changes in layout and text of the Advanced
798 - Xvnc: Minor bugfix which should prevent potential dereference of a
801 - Unix viewer: Now viewer window would be raised on beep (bell)
802 event, unless new -noraiseonbeep option is provided in the command
803 line or "raiseOnBeep" resource set to False.
805 - One more packaging option for the Unix source: ready to build
806 archive with Zlib and JPEG libraries inside.
808 - Other minor fixes and cleanups.
810 ----------------------------------------------------------------------
814 - Win32 server: added support for reverse connections on ports other
815 than 5500, modified patch from Steve Kann.
817 - Win32 viewer: added support for new command-line options:
818 -noshared and -encoding XXX.
820 - Bugfixes in Win32 viewer: changes in exception handling eliminate
821 Borland C++ compilation problems causing application crashes on
822 repetitive connections, notably in the listen mode. Also, now
823 warning exceptions causing disconnects are reported to user,
824 except for the case when a user has closed the viewer window.
826 - Better packaging in Win32 version: self-installing package is
827 available, vncviewer now shows correct icon image.
829 - Unix vncviewer: Default tunneling command template has been
830 changed, to allow tunneled connections to hosts where only
831 loopback VNC connections are enabled. New -via <GATEWAY>
832 command-line option provides enhanced tunneling functionality, now
833 one can make vncviewer tunnel connections to a VNC host via third
834 machine acting as a gateway.
836 - Java viewer: Addition of new parameters PASSWORD, "Show Controls",
837 and "View Only", modified patch from Steve Kann.
839 ----------------------------------------------------------------------
843 - Tight encoding is now configurable and can operate at different
844 compression levels where low compression levels are very fast in
845 terms of CPU usage. New "-compresslevel N" option implemented in
846 vncviewer to set compression levels for Tight encoding (1 - fast,
849 - Enhanced techniques to split large rectangles in Tight encoder;
850 now it tries to find large solid-color areas and send them in
853 - Lossy JPEG compression in Tight encoding has been implemented, new
854 "-quality N" vncviewer option should be used to enable this
855 feature (0 - low image quality and best compression, 9 - best
856 image quality). JPEG compression is used only for screen areas
857 that seem to be suitable for JPEG compression (although algorithms
858 to detect such areas are not perfect, of course).
860 - New "XCursor" and "RichCursor" encodings implemented. They are
861 used to transmit cursor shape updates from server to clients
862 ("local cursor" feature requested by many users). Mouse movement
863 no longer causes framebuffer updates to happen, vncviewer
864 processes mouse locally when this feature is active. New
865 -nocursorshape vncviewer option turns this feature off.
867 - A number of recent changes from both TridiaVNC and AT&T's releases
868 merged into the source, now the code is based on version 3.3.3r2
869 for Unix part, and on 3.3.3r9 for Win32.
871 - Unix vncviewer: When -tunnel option is specified in the command
872 line, special rules are now used to choose preferred encoding. Now
873 viewer does not think that server is running on the same machine
874 when tunneling is on and the preferred encoding is now "tight"
875 with default compression instead of raw.
877 - Xvnc: Rules to set default pixel formats have been changed: now
878 they are RGB565 instead of BGR556 for color depth 16, and RGB888
879 instead of BGR888 for depth 24. This makes Xvnc compatible with
880 Imlib renderer used in Gnome and also helps to avoid unnecessary
881 pixel format translations in many cases.
883 - Xvnc: X11 modifier mapped to META key is now Mod4 instead of Mod1.
884 New -compatiblekbd option implemented in Xvnc to force META and
885 ALT keys behave the same way as they do in the original AT&T's
888 - A number of bugs fixed: viewer crashes after inflate() call, Xvnc
889 CoRRE encoding problems, Xvnc bit-order issues in XCursor and
890 RichCursor encodings, etc.
892 - Java viewer now supports Tight encoding and cursor shape updates.
893 Drawing techniques were changed, settings "Raw pixel drawing:
894 Fast/Reliable" and "CopyRect: Fast/Reliable" removed from the
895 Options panel since they do not make sense in new drawing model.
897 - Other new features, optimizations, fixes and cleanups, see
900 ----------------------------------------------------------------------
902 * VNC Tight Encoding 1.1
904 - New ``gradient'' filter implemented in servers (it can be disabled
905 in Xvnc with new -lazytight option). The filter preprocess
906 full-color screen areas prior to compression in order to achieve
907 better compression ratios (with the cost of slower compression).
908 Vncviewers of version 1.0 had support for this filter already, but
909 there was small bug causing image distortions in certain cases. So
910 it is recommended to upgrade both servers and viewers.
912 - Stupid bug fixed: extra unused color was included in palettes in
913 many cases; compression ratios used to be worse than they should
916 - The algorithm used to split large rectangles into parts has been
917 changed. This change can increase compression ratios in many
920 - Byte-order issues in servers have been (hopefully) fixed.
922 - Performance tuning, code rewrites and cleanups in various places.
