+Cygwin/X Release Notes
+======================
+
+Release X11R6.7
+===============
+
+Cygwin/X has continued its rapid pace of development that it has sustained
+since Spring 2001 and this release shows it, we now have: a stable and fast
+multi-window mode, seamless clipboard integration, a configurable tray menu
+icon, popups on error messages pointing users to the log file and our mailing
+list, the beginnings of indirect 3D acceleration for OpenGL applications,
+improved non-US keyboard and clipboard support, and only a handful of bugs
+that continue to be reported.
+
+Between the XFree86 4.3.0 release and the X.Org X11R6.7 release the Cyg-
+win/XFree86 project broke away from The XFree86 Project, Inc. due to a lack
+of support from the XFree86 project.  As such, the Cygwin/XFree86 project was
+renamed to the Cygwin/X project and the upstream source code tree that Cyg-
+win/X pulls from and pushes to is now the tree managed by the X.Org Founda-
+tion.  The Cygwin/X project has seen a rush of development and interest in
+the project since the split; one metric showing this is that the number of
+CVS committers we have has gone from zero to six.
+
+The most outstanding features of this release are
+
+   o Major multi-window mode improvements. (Takuma Murakami, Earle F. 
+     Philhower III)
+
+   o Initial work of accelerated OpenGL using the windows OpenGL drivers. 
+     (Alexander Gottwald)
+
+   o Massive rework of clipboard integration with windows. (Harold L Hunt II,
+     Kensuke Matsuzaki)
+
+   o Improved Japanese clipboard and keyboard support. (Kensuke Matsuzaki,
+     Takuma Murakami, Alexander Gottwald)
+
+   o Customizable tray menu icon allowing shortcuts to start programs,
+     etc.(Earle F. Philhower III)
+
+   o New icons. (Jehan Bing, Michael Bax, Benjamin Rienfenstahl)
+
+   o Fix some multi-monitor problems.(Takuma Murakami)
+
+   o Fix repeated key strokes. (Ivan Pascal)
+
+   o Automatic keyboard layouts for the most frequently used keyboard lay-
+     outs. (Alexander Gottwald)
+
+   o Built in SHM support with detection of the SHM engine (cygserver).
+     (Ralf Habacker, Harold L Hunt II)
+
+   o Merged in work on the NativeGDI engine. (Alan Hourihane)
+
+OpenGL with Cygwin/X
+====================
+
+Cygwin/X has supported GLX only with software rendering provided by the Mesa
+library. Starting with X11R6.7 we add support for hardware accelerated OpenGL.
+
+This support is still under development and still has some bigger problems. 
+To provide both versions (the stable software rendering and the new hardware
+accelerated) we ship to binaries. XWin.exe contains the software rendering 
+and XWin_GL.exe uses the hardware acceleration provided by the windows drivers.
+
+The known problems with hardware accelerated OpenGL are:
+
+   o Only multiwindow mode is useful. In the other modes the OpenGL output 
+     does not align with the X11 windows.
+
+   o Using two programs which require different visuals will fail. For example
+     glxgears and glxinfo will not work without restarting XWin_GL.exe.
+
+   o OpenGL extensions and functions from OpenGL 1.2 and later should work 
+     but are not completely tested.
+
+   o The standard Windows OpenGL driver will produce no output. Use the one 
+     from your video adapter vendor.  
+
+If you notice problems with some programs please send a message with the 
+logfile /tmp/XWin.log and a short error description to <cygwin-xfree@cygwin.com>
+
+The hardware accelerated OpenGL was tested using: 
+
+   o glxgears
+   o glxinfo
+   o blender
+   o tuxkart
+   o GLUT demos (some did fail)
+   o tuxracer (currently not working)
+
+    
+Release X11R6.8
+===============
+
+Having reached a quite mature state in release X11R6.7 the development 
+has slowed down a little bit. Some of the former active developers have
+retired or cut their work for the Cygwin/X project due to conflicts with 
+job, study and family. 
+
+The X11R6.8 release now includes major improvements from the xserver project.
+This includes the XFixes, the Damage and XEVIE extension which is a major
+step towards allowing Cygwin/X to have real transparency. 
+
+OpenGL with Cygwin/X
+====================
+
+The OpenGL support has lost some of it's limitations from the last release 
+and should be much more stable. But due to missing wide spread testing in 
+the community it is still available in a separate program. XWin still uses 
+the old software OpenGL which is known to be stable.
+
+The known problems with hardware accelerated OpenGL are:
+
+   o Only multiwindow mode is useful. In the other modes the OpenGL output 
+     does not align with the X11 windows.
+
+   o OpenGL extensions and functions from OpenGL 1.2 and later should work 
+     but are not completely tested.
+
+   o The standard Windows OpenGL driver will produce no output. Use the one 
+     from your video adapter vendor.

+logfile /tmp/XWin.log and a short error description to <cygwin-xfree@cygwin.com>
