2006-05-15 Steven Carr <scarr@jsa-usa.com>
* The great UltraVNC Compatibility Commit!
libvncserver now supports the following messages:
SetSingleWindow - Select a single window to be the source of the
framebuffer.
ServerInput - Disable and blank the servers display
TextChat - TextChat between the remote/local user
(Bandwidth friendly VS the Notepad approach)
FileTransfer - Emulates a Windows Filesystem to the viewer
(Currently does not support Delta Transfers)
(Currently does not support Sending Directories)
UltraZip - Improved UltraZip support
* Improved Statistics SubSystem, now supports all encodings
* RFB 3.8 support! Error Messages are a 'Good Thing' (tm)
* Default to identify as RFB 3.6 to emulate UltraVNC server
(Server now has the ability to set the RFB version reported)
(permits the viewer to identify the server has FileTransfer ability)
* Client Encoding AutoSelection Supported (UltraViewer is speed aware)
* libvncclient has improved server detection/capabilities logic!
2006-05-13 Karl Runge <runge@karlrunge.com>
* minilzo.c,minilzo.h,lzoconf.h: switch to non-CRLF versions.
* libvncclient/Makefile.am: add minilzo.c, minilzo.h, lzoconf.h
