2.1.0	Oct 25, 1999		o New code for S514 PCI Card
				o New CHDLC and Frame Relay drivers
				o PPP and X25 are not supported in this release    

2.1.1	Nov 30, 1999		o PPP support for S514 PCI Cards

				o Asynchronous CHDLC support (Secondary Port)
				o cfgft1 GUI csu/dsu configurator
				o wancfg GUI configuration file 
				  configurator.
				o Architectual directory changes.

beta-2.1.4 Jul 2000		o Dynamic interface configuration:
					Network interfaces reflect the state
					of protocol layer.  If the protocol becomes
					disconnected, driver will bring down
					the interface.  Once the protocol reconnects
					the interface will be brought up. 
					
					Note: This option is turned off by default.

				o Dynamic wanrouter setup using 'wanconfig':
					wanconfig utility can be used to
					shutdown,restart,start or reconfigure 
					a virtual circuit dynamically.
				     
					Frame Relay:  Each DLCI can be: 
						      created,stopped,restarted and reconfigured
						      dynamically using wanconfig.
					
						      ex: wanconfig card wanpipe1 dev wp1_fr16 up
				  
				o Wanrouter startup via command line arguments:
					wanconfig also supports wanrouter startup via command line
					arguments.  Thus, there is no need to create a wanpipe#.conf
					configuration file.  

				o Socket based x25api update/bug fixes.
					Added support for LCN numbers greater than 255.
					Option to pass up modem messages.
					Provided a PCI IRQ check, so a single S514
					card is guaranteed to have a non-sharing interrupt.

				o Fixes to the wancfg utility.
				o New FT1 debugging support via *pipemon utilities.
				o Frame Relay ARP support Enabled.

beta3-2.1.4 Jul 2000		o X25 M_BIT Problem fix.
				o Added the Multi-Port PPP
				  Updated utilites for the Multi-Port PPP.

2.1.4	Aut 2000
				o In X25API:
					Maximum packet an application can send
					to the driver has been extended to 4096 bytes.

					Fixed the x25 startup bug. Enable 
					communications only after all interfaces
					come up.  HIGH SVC/PVC is used to calculate
					the number of channels.
					Enable protocol only after all interfaces
					are enabled.

				o Added an extra state to the FT1 config, kernel module.
				o Updated the pipemon debuggers.

				o Blocked the Multi-Port PPP from running on kernels
				  2.2.16 or greater, due to syncppp kernel module
				  change. 
	  
beta1-2.1.5 	Nov 15 2000
				o Fixed the MulitPort PPP Support for kernels 2.2.16 and above.
				  2.2.X kernels only

				o Secured the driver UDP debugging calls
					- All illegal netowrk debugging calls are reported to
					  the log.
					- Defined a set of allowed commands, all other denied.
					
				o Cpipemon
					- Added set FT1 commands to the cpipemon. Thus CSU/DSU
					  configuraiton can be performed using cpipemon.
					  All systems that cannot run cfgft1 GUI utility should
					  use cpipemon to configure the on board CSU/DSU.


				o Keyboard Led Monitor/Debugger
					- A new utilty /usr/sbin/wpkbdmon uses keyboard leds
					  to convey operatinal statistic information of the 
					  Sangoma WANPIPE cards.
					NUM_LOCK    = Line State  (On=connected,    Off=disconnected)
					CAPS_LOCK   = Tx data     (On=transmitting, Off=no tx data)
					SCROLL_LOCK = Rx data     (On=receiving,    Off=no rx data
					
				o Hardware probe on module load and dynamic device allocation
					- During WANPIPE module load, all Sangoma cards are probed
					  and found information is printed in the /var/log/messages.
					- If no cards are found, the module load fails.
					- Appropriate number of devices are dynamically loaded 
					  based on the number of Sangoma cards found.

					  Note: The kernel configuraiton option 
						CONFIG_WANPIPE_CARDS has been taken out.
					
				o Fixed the Frame Relay and Chdlc network interfaces so they are
				  compatible with libpcap libraries.  Meaning, tcpdump, snort,
				  ethereal, and all other packet sniffers and debuggers work on
				  all WANPIPE netowrk interfaces.
					- Set the network interface encoding type to ARPHRD_PPP.
					  This tell the sniffers that data obtained from the
					  network interface is in pure IP format.
				  Fix for 2.2.X kernels only.
				
				o True interface encoding option for Frame Relay and CHDLC
					- The above fix sets the network interface encoding
					  type to ARPHRD_PPP, however some customers use
					  the encoding interface type to determine the
					  protocol running.  Therefore, the TURE ENCODING
					  option will set the interface type back to the
					  original value.  

					  NOTE: If this option is used with Frame Relay and CHDLC
						libpcap library support will be broken.  
						i.e. tcpdump will not work.
					Fix for 2.2.x Kernels only.
						
				o Ethernet Bridgind over Frame Relay
					- The Frame Relay bridging has been developed by 
					  Kristian Hoffmann and Mark Wells.  
					- The Linux kernel bridge is used to send ethernet 
					  data over the frame relay links.
					For 2.2.X Kernels only.

				o Added extensive 2.0.X support. Most new features of
				  2.1.5 for protocols Frame Relay, PPP and CHDLC are
				  supported under 2.0.X kernels. 

beta1-2.2.0 	Dec 30 2000
				o Updated drivers for 2.4.X kernels.
				o Updated drivers for SMP support.
				o X25API is now able to share PCI interrupts.
				o Took out a general polling routine that was used
				  only by X25API. 
				o Added appropriate locks to the dynamic reconfiguration
				  code.
				o Fixed a bug in the keyboard debug monitor.

beta2-2.2.0	Jan 8 2001
				o Patches for 2.4.0 kernel
				o Patches for 2.2.18 kernel
				o Minor updates to PPP and CHLDC drivers.
				  Note: No functinal difference. 

beta3-2.2.9	Jan 10 2001
				o I missed the 2.2.18 kernel patches in beta2-2.2.0
				  release.  They are included in this release.

Stable Release
2.2.0		Feb 01 2001
				o Bug fix in wancfg GUI configurator.
					The edit function didn't work properly.


bata1-2.2.1	Feb 09 2001
			o WANPIPE TTY Driver emulation. 
			  Two modes of operation Sync and Async.
				Sync: Using the PPPD daemon, kernel SyncPPP layer
				      and the Wanpipe sync TTY driver: a PPP protocol 
				      connection can be established via Sangoma adapter, over
				      a T1 leased line.
			
				      The 2.4.0 kernel PPP layer supports MULTILINK
				      protocol, that can be used to bundle any number of Sangoma
				      adapters (T1 lines) into one, under a single IP address.
				      Thus, efficiently obtaining multiple T1 throughput. 

				      NOTE: The remote side must also implement MULTILINK PPP
					    protocol.

				Async:Using the PPPD daemon, kernel AsyncPPP layer
				      and the WANPIPE async TTY driver: a PPP protocol
				      connection can be established via Sangoma adapter and
				      a modem, over a telephone line.

				      Thus, the WANPIPE async TTY driver simulates a serial
				      TTY driver that would normally be used to interface the 
				      MODEM to the linux kernel.
				
			o WANPIPE PPP Backup Utility
				This utility will monitor the state of the PPP T1 line.
				In case of failure, a dial up connection will be established
				via pppd daemon, ether via a serial tty driver (serial port), 
				or a WANPIPE async TTY driver (in case serial port is unavailable).
				
				Furthermore, while in dial up mode, the primary PPP T1 link
				will be monitored for signs of life.  

				If the PPP T1 link comes back to life, the dial up connection
				will be shutdown and T1 line re-established.
			

			o New Setup installation script.
				Option to UPGRADE device drivers if the kernel source has
				already been patched with WANPIPE.

				Option to COMPILE WANPIPE modules against the currently 
				running kernel, thus no need for manual kernel and module
				re-compilatin.
			
			o Updates and Bug Fixes to wancfg utility.

bata2-2.2.1	Feb 20 2001

			o Bug fixes to the CHDLC device drivers.
				The driver had compilation problmes under kernels
				2.2.14 or lower.

			o Bug fixes to the Setup installation script.
				The device drivers compilation options didn't work
				properly.

			o Update to the wpbackupd daemon.  
				Optimized the cross-over times, between the primary
				link and the backup dialup.

beta3-2.2.1	Mar 02 2001
			o Patches for 2.4.2 kernel.

			o Bug fixes to util/ make files.
			o Bug fixes to the Setup installation script.

			o Took out the backupd support and made it into
			  as separate package.
			  
beta4-2.2.1     Mar 12 2001

		o Fix to the Frame Relay Device driver.
			IPSAC sends a packet of zero length
			header to the frame relay driver.  The
			driver tries to push its own 2 byte header
			into the packet, which causes the driver to
			crash.

		o Fix the WANPIPE re-configuration code.
			Bug was found by trying to run  the cfgft1 while the
			interface was already running.  

		o Updates to cfgft1.
			Writes a wanpipe#.cfgft1 configuration file
			once the CSU/DSU is configured. This file can
			holds the current CSU/DSU configuration.
