WinVNC Version History

Version 3.3.7 (RealVNC Version 3.3.7)
Changes from 3.3.6:

	Removed use of Win32 HRGN API completely.  Regions are now implemented
	using the X11 region code, nobbled just enough to build properly.

	Fixed a memory leak in the Win32 HRGN API, just in case it ever gets fixed.

	Changed the VNCHooks defaults to use deferred updates, and to hook key
	press events - may cause performance issues and ActiveX issues, but
	they are the best settings for most systems.

	Fixed a bug in the processing of passwords supplied in the Properties dialog
	that affected use of Latin-1 characters with ASCII codes of 128 or above.

Version 3.3.6 (RealVNC Version 3.3.6)
Changes from 3.3.5:

	The WinVNC service helper now attempts to contact the server for
	up to a minute, to cope with users logging on to XP machines before
	the service has had a chance to start.  Avoids the tray icon not being
	shown.

	When run as an application, WinVNC will always display the tray icon.

	Renamed omnithread2_rt.dll to othread2.dll to work around a
	problem with the InnoSetup installer.

	Added concurrency-protection around all uses of Win32 HRGN API
	routines, to avoid a possible bug in the Win32 API when used
	by multi-threaded programs.

	Clipboard contents are now sent to clients even if no graphical
	updates are available.

	Advanced VNCHooks.dll settings can now be specified on a per-
	machine basis, not just per-user.

	Fixed rare condition in VNCHooks.dll that could prevent user
	profiles from being unloaded correctly.

	Fixed timeout bug in HTTP server.

Version 3.3.5 (RealVNC Version 3.3.5)
Changes from 3.3.4b1:

	A race-condition when first configuring the server has been fixed.

	The password field in the Properties dialog is now handled better.

	Active Desktop backgrounds can now be handled by RemoveWallpaper.

	Mouse wheels are now supported.

	The Add New Client dialog now accepts specifications of the form
	<hostname>:<display> or <hostname>:<port>, to allow listening
	viewers to be used that are listening on ports other than the default.

	The AllowEditClients registry option is used like AllowProperties,
	and allows VNC to be configured not to show the Add New Client or
	Kill All Clients menu items in the tray icon menu.

	Implemented the -reinstall option, which unregisters the WinVNC
	service if registered, then re-registers it.

	Fixed bug in fast blit code when pixel format changes from one
	supporting fast blits to a munged format.

Version 3.3.4b1 (RealVNC Version 3.3.4, Beta Release 1)
Changes from AT&T Labs' Version 3.3.3 Revision 10:

	Delphi apps should no longer crash when run alongside VNC.

	WinVNC nows gives a slightly more useful error message if -install is used
	while the service is already registered,

	The logging-related buffer overflow exploits should no longer be possible.

	Added several options to the Properties dialog.

	The current password is not stored in the Properties dialog when
	displayed, preventing it from being read by other programs.

	The HTTP server can be disabled by the HTTPConnect registry key.

	LockSettings can now lock Windows 2000/XP boxes on disconnect.

	Improved update tracking code.

	Fixed LF/CRLF problem in HTTP server.

	Clients are no longer disconnected if pixel format changes.
	They WILL be disconnected if the display size changes.

	Update hooking and transmission now decoupled.

	Optimised checking of update regions for changes for case where
	clients are connected which do not request updates (often).

	Optimised for multiple simultaneous client connections.

	Upgraded omnithread library.

	Rationalised source tree a little.

	Renamed "log" to "vnclog" to avoid log() function clashes.

Version 3.3.3 (VNC Version 3.3.3, revision 10)
Changes from Version 3.3.3 Revision 9:

	Fixed signature of RegisterServiceProcess.

	Fixed incorrect call of errno to call wsagetlasterror.

	Fixed keymapping of circumflex character, etc.

	Added extra debug logging in desktop hook code.

	Removed warning about connected users in logoff handling code.

Version 3.3.3 (VNC Version 3.3.3, revision 9)
Changes from Version 3.3.3 Revision 8:

	Fixed handling of empty (match all) AuthHosts filters.

	WinVNC.log will now be moved to WinVNC.log.bak when WinVNC runs.

Version 3.3.3 (VNC Version 3.3.3, revision 8)
Changes from Version 3.3.3 Revision 7:

-=-	Bug Fixes to WinVNC:

	Fixed clipboard handling.

	Fixed AddClient semantics in vncServer to avoid a socket leak.

	Fixed AuthHosts dialog display.  Now flashes titlebar/tray button if not foreground window.

	Fixed AuthHosts string parsing.  Filters such as 10.0.0.1 no longer match 10.0.0.10.

	QuerySetting didn't work correctly if the AuthHosts string was empty.  Fixed.

	Closing the screen-saver now works, so it's back in there.

	Changed the shutdown-dialog behaviour.  It now only operates in application mode.

-=-	Bug Fixes to VNCHooks:

	Added HooksType() function to VNChooks so that the library may be replaced with a reliable
	hooking version easily.
	
	VNCHooks DLL did not remove properties from windows correctly when
	UnsetHooks() was called.  Fixed.

-=-	Minor Fixes

	Implemented the wallpaper-culling feature during remote connections.

	Added automatic culling of "idle" connections, if required, via the IdleTimeout setting.
	An idle connection is one in which the client has sent no data for a fixed period,
	whether the data be an update request, input events, or clipboard data.

	Only incoming connections are now checked for validity.  Outgoing (Add New Client)
	or CORBA-initiated connections are not checked via AuthHosts.

Version 3.3.3 (VNC Version 3.3.3, revision 7)
Changes from Version 3.3.3 Revision 6:

	WinVNC did not correctly handle Winsock1.1, causing all client connections to be
	erroneously dropped by the anti-DoS code.  Now fixed.

Version 3.3.3 (VNC Version 3.3.3, revision 6)
Changes from Version 3.3.3 Revision 4:

	The anti denial-of-service blacklist code was very buggy.  It's now fixed.

	An serious potential deadlock condition in the negotiation phase of new
	clients has been fixed.  The problem was incredibly rare on uniprocessors
	but much more noticable on multiprocessors, unsurprisingly.

	Pointer is now rendered slightly better.

Version 3.3.3 (VNC Version 3.3.3, revision 4)
Changes from Version 3.3.3 Revision 3:

	Implemented some simple Denial-of-Service protection.  After five consecutive failed
	connection attempts from a client, that client is "blacklisted" for ten seconds.
	In addition, connections which hang before the authentication stage has completed are
	timed out after thirty seconds, to prevent malicious users gradually eating up socket
	resources.

	Corrected a bug initialising the back-buffer.

	Added hooking for dialog boxes, menus and scrollbars.  Seems to fix some dialogs but not
	many scrollbars or menus..

	Improved the GetChangedRect code with some alignment patches suggested by Will Dean.

	Fixed an *IDIOTIC* bug in the handling of user-specific settings.  They were completely
	broken before.  Now they should work.  I'm such an idiot.  Idiot idiot idiot.
	See MS Knowledge Base articles Q168877 & Q199190.

	The idiot bug-fix above broke roaming profiles on NT domains!  That's now fixed, too.
	Idiot idiot idiot.

	Added a dialog to query whether to accept or reject incoming connections.  The dialog is
	currently controlled ONLY via the registry!  The AuthHosts setting is now extended, while
	some new user-specific settings are provided so that users can tailor the query feature.
	Relevant keys are:
	- QuerySetting (DWORD) (local&global user-specific)
		[Least secure]
		0 - Accept or Query.  If AuthHosts says Reject then query, otherwise Accept.
		1 - Accept or Reject.  Reject if AuthHosts says so, otherwise Accept.
		2 - Obey AuthHosts.  Obey AuthHosts Accept, Query, Reject settings. [Default!]
		3 - Query or Reject.  If AuthHosts says Reject then Reject, otherwise Query.
		4 - Ultimate Paranoia.  If AuthHosts says Accept then Query, otherwise Reject!
		[Most secure]

		Summary:	Actual Effect
		Setting		Accept	Query	Reject
		0			a		a		q
		1			a		a		r
		2			a		q		r
		3			q		q		r
		4			q		r		r

	- QueryTimeout (DWORD) (local&global user-specific)
		Number of seconds before Accept/Reject dialog should timeout and reject.
	- AuthHosts (SZ) (machine-local)
		Match terms may now start with "-", "+" or "?".  "?" indicates that the connection
		attempt should be queried.

Version 3.3.3 (VNC Version 3.3.3, revision 3)
Changes from Version 3.3.3 Revision 2:

	Implemented Will Dean's DIBsection patch to retrive screen data.  This reduces
	both the retrieval time & the memory usage of WinVNC but currently only works
	for VNC-format-compatible 16 and 32 bit displays.  If your display is incompatible
	then WinVNC falls back to the old, slow, memory hungry mode.

	Fixed a bug in VNCHooks which cause very large updates to be spuriously created on occasion.

	vncKeymap now filters out the three Lock keys (CapsLock, NumLock, ScrollLock), so that
	they can be safely used at the client side without generating random keystrokes on the
	server.

Version 3.3.3 (VNC Version 3.3.3, revision 2)
Changes from Version 3.3.3 Revision 1:

	Added the new "Disable Local Keyboard & Pointer" option to the Properties dialog.
	This features currently allows the keyboard & pointer of the sever machine to be
	disabled while a remote connection is in progress.
	The feature only works under Windows NT at present.
	NB:This is a BETA feature, with a known limitation - if the setting
	is changed then all clients must disconnect and reconnect to achieve the desired
	effect.

	The -connect command-line option has been added, allowing new outgoing connections
	to be made using a script or an icon.

	The Add New Client and -connect options now make shared outgoing connections, since
	this is usually preferable to unshared outgoing connections.

	Improved the way preferences are loaded, reducing the number of times the client will
	be disconnected when settings are loaded & saved.
