cifX Driver Version History:

V1.2.3.0
-----------------
 - Setup modified to support Windows 8.1
 - COM state notification (CIFX_NOTIFY_COM_STATE) do not deliver actual communication state
   pvData is always a NULL pointer
 - NDIS Update:
    * update to new NDIS firmware interface
    * added support for system hibernation
    * fixed sporadic link status errors in interrupt mode
    * send error statistics were not updated

V1.2.2.0
-----------------
 - Fixed Memory leaks when restarting devices (cifXSetup / xDriverRestartDevice)
 - Updated cifX Toolkit to V1.1.4.0
 - Updated Bootloader to V1.4.12.0

V1.2.1.0
-----------------
 - Setup modified to support Windows 8
 - Updated cifX Toolkit to V1.1.3.0
 - Updated Bootloader to V1.4.10.0

V1.2.0.0
-----------------
 - Extended to provide bus-driver functionality for the cifXNDIS Device Driver
 - Added initial version of the cifXNDIS Device Driver
 - Updated Bootloader to V1.4.7.0

V1.1.1.0
-----------------
 - netX API (nxDrvDownload) may insert configuration database multiple times in 
   registry if configuration in run feature of SYCON.NET is used
 - Added command to set system time if a RTC is available on the hardware
 - Added support for MRAM via CIFX-API functions
 - Updated Bootloader to V1.4.6.0

V1.1.0.0
-----------------
 - Thread safety of netX API improved
 - Unexpected packet callback (pfnRecvPktCallback on xSysdeviceDownload, xChannelDownload) does not deliver 
   the correct packets not belonging to downloads
 - Unaligned access to DPM may deliver wrong data, depending on the used PCI / PCIe Bridge
 - Handling xSysdeviceInfo, xChannelInfo, xChannelCommonState, xChannelExtendedState outside of
   KMDF Framework to achieve better performance under Windows Vista / 7
 - Notification Callback functions (xChannelRegisterNotification) are not performed with higher thread priority.
    * THREAD_PRIORITY_TIME_CRITICAL for Sync callback
    * THREAD_PRIORITY_HIGHEST for all others.

V1.0.5.0
-----------------
 - netX API (nxDrvDownload) does not cleanup channel directories on multi-channel devices (e.g. CIFX50-2DP),
   when performing a firmware download. This may result in an inconsistent configuration after firmware
   update, and SYCON.NET may not be able to update the configuration persistently on channel != 0.

V1.0.4.0
-----------------
 - IOCTL's for cyclic data handled outside of KMDF framework to achieve better performance
 - Return values for xSysdevicePut/GetPacket() and xChannelPut/GetPacket() changed from CIFX_IOCONTROL_FAILED to CIFX_INVALID_POINTER if pointer checking fails
 - Updated to latest DIFX (Driver Installer Framework) to allow easier upgrading of drivers
 - Updated Bootloader to V1.3.6.0

V1.0.3.0
-----------------
 - netJACK 100 Support added
 - xChannelRegisterNotification does not pass expected notification data on callback
 - Updated Bootloader to V1.3.4.0

V1.0.2.0
-----------------
 - cifXHandleWarmstartParameter(), checking receive packet state fixed
 - Updated internal security permissions
 - Updated Bootloader to V1.3.2.0

V1.0.1.0
-----------------
Bugfix:
 - xSysdeviceFindFirst will not call ReceivePacket function on native 32Bit and 64 Bit. 
   32Bit application on 64Bit OS works ok.
 - NXSB-PCA test functions added (only 32Bit native and 64 Bit native)
 - xDriverMemoryPointer always needed pulChannelSize / pulChannelStartOffset even 
   if CIFX_NO_CHANNEL was requested
 - Downloading loadable modules (.NXO) may fail on larger files due to the last 
   confirmation packet taking longer than expected

V1.0.0.0
-----------------
 - Setup creates InstallDirectory Entry at wrong location. This results
   that cifXTest / cifXSetup cannot be opened from Control Panel, before a cifX
   card was inserted
 - xChannelSyncState Parameters updated (added Timeout)
 - Loadable modules not working correctly
 - xChannelPLCMemoryPointer returns invalid pointer on success
 - Interrupts for NXPCA-PCI not working
 - Timings for NXPCA-PCI boards were not written. DIP switch on card did only
   work in 8 Bit Mode.
 - Wrong timings for NXPCA-PCI Boards in .INF File. If an older version was
   installed it might be necessary to update the timings in the registry
 - netPLC was not detected
 - Driver may cause Blue Screen if Invalid Pointer is passed to xDriverRestartDevice
 - USER_GetWarmstartParameters(), using short file name to open file fixed

Based on Toolkit V1.0.0.0

V0.10.0.0
-----------------
 - Notification callbacks added

 - xDriverGetInformation did not work from 32Bit Applications running on x64 Windows
 - xDriverGetErrorDescription now working correctly
 - Added Cyclic Timer for COS Flag handling
 - xChannelFindFirst-/FindNextFile and xSysdeviceFindFirst-/FindNextFile were not working
   on 64Bit platforms using a 32 Bit application

   on 64Bit platforms

cifXSetup:
 - Support for cards with Slot numbers updated
