-
-3.1.0	January 30, 1997
-
-	o Implemented IOCTL for executing adapter commands.
-	o Fixed a bug in frame relay code causing driver configured as a FR
-	  switch to be stuck in WAN_DISCONNECTED mode.
-
-3.0.0	December 31, 1996
-
-	o Uses Linux WAN Router interface
-	o Added support for X.25 routing
-	o Miscellaneous bug fixes and performance improvements
-
-2.4.1	December 18, 1996
+ACKNOWLEDGEMENTS
 
-	o Added support for LMI and Q.933 frame relay link management
+This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed
+by Sangoma Technologies Inc. for Linux 2.2.x.  Success of the WANPIPE
+together with the next major release of Linux kernel in summer 1996 commanded
+adequate changes to the WANPIPE code to take full advantage of new Linux
+features.
 
-2.3.0	October 17, 1996
+Instead of continuing developing proprietary interface tied to Sangoma WAN
+cards, we decided to separate all hardware-independent code into a separate
+module and defined two levels of interfaces - one for user-level applications
+and another for kernel-level WAN drivers.  WANPIPE is now implemented as a
+WAN driver compliant with the WAN Link Driver interface.  Also a general
+purpose WAN configuration utility and a set of shell scripts was developed to 
+support WAN router at the user level.
 
-	o All shell scripts use meta-configuration file
-	o Miscellaneous bug fixes
+Many useful ideas concerning hardware-independent interface implementation
+were given by Mike McLagan <mike.mclagan@linux.org> and his implementation
+of the Frame Relay router and drivers for Sangoma cards (dlci/sdla).
 
-2.2.0	July 16, 1996
+With the new implementation of the APIs being incorporated into the WANPIPE,
+a special thank goes to Alan Cox in providing insight into BSD sockets.
 
-	o Compatible with Linux 2.0
-	o Added uninstall script
-	o User's Manual is available in HTML format
+Special thanks to all the WANPIPE users who performed field-testing, reported
+bugs and made valuable comments and suggestions that help us to improve this
+product.

-	o Added support for synchronous PPP
