List Of New Features & Changes

---------------------------------------------------------------------                      

                         Version 3.3.0 
                         June 30, 2010
                        Elo TouchSystems

====================================================================== 


Summary of new features & changes in driver v3.3.0:
---------------------------------------------------

  1. Lighter version of calibration utility (elovaLite) to support
     various window managers. Type "/etc/opt/elo-usb/elovaLite --help" 
     for available command line parameters and usage.

  2. New touch mode added to the serial driver to send only Button Up
     events, instead of Button Down and Button Up events, to Xwindows 
     when a touch is sensed. This mode only works with special 
     applications that use only Button Up events.

  3. Support for newer Xorg Xserver versions [ Xserver v1.5/1.6/1.7/1.8].

  4. Support for Motif versions 3.0 [libXm.so.3] and 4.0 [libXm.so.4].

  5. Support for 64 bit AMD/Intel x86_64 platform added. Visit the   
     Linux downloads section at www.elotouch.com to download the 
     64 bit AMD/Intel x86_64 platform driver package or the standard 
     32 bit Intel i686 (x86) platform driver package.
 
  6. Adds support for multiple video screens using the Nvidia Twinview setup. 
     Nvidia Twinview, Xorg Xinerama and Xorg non-Xinerama based multiple 
     video screens are now supported by the driver.

  7. Adds support for serial ports provided by RocketPort Serial cards. 
     [ example: /dev/ttyR0, /dev/ttyR1, etc ]

  8. The calibration utilities provide a default timeout of 30 seconds for 
     each calibration target. The timeout can be disabled or changed using
     commandline option --caltargettimeout. They also provides a list of 
     available video and touch devices for calibration and options to select 
     specific devices for calibration. Formatted the elova output and help 
     information width to 80 columns for low resolution displays and text 
     consoles. Type "/etc/opt/elo-usb/elova --help" or 
     "/etc/opt/elo-usb/elovaLite --help" for available command line parameters 
     and usage. 

  9. Adds support for recent touchscreen controllers.
 
 10. Adds support for Emacs text editor in the graphic control panel
     to view the Readme.txt file.  

 11. Ignore non-critical errors generated by Xwindows for "X_FreeColors" errors
     in the calibration utilities.

 12. The serial driver path has changed from "/etc/opt/elo" to "/etc/opt/elo-ser" 
     and the Elo device installation path has changed from "/dev/elo" to 
     "/dev/elo-ser" respectively. Files within the driver package have been 
     reorganized.

 13. The previous command line parameters for all the driver components are now 
     obsolete. All long command line options in the driver components have been 
     modified to use the "--" format instead of the "-" format. Use the "--help" 
     option to see all the available commandline options. 

 14. This driver release is a major change from the previous version. 
     Hence some features or options from the previous driver versions 
     are now obsolete.
