   Title: Release Notes
Product: GNAT Box System Runtime 3.10 
    Date: August 2000

Introduction
Many changes have occurred since the GNAT Box Firewall systems was first
introduced in 1996.  The amazing system that booted and ran
entirely from a single 3.5" floppy diskette was the first compact
cost effective firewall system on the market.  In 1996 many people had
a hard time understanding how such a compact cost effective firewall
could actually exist let alone provide solid security.   Over the years
the GNAT Box system has proven itself; from receiving ICSA certification
for version 1.0 in 1996 to besting firewalls that cost 10-20 times more 
and provide 20-50 times less performance.  Now after 4 1/2 years of 
growth the GNAT Box system has come to a crossroads.

With the introduction of version 3.1.0 of the GNAT Box system software
there will be a difference in the system features based on the target
platform.  There are two distinct platforms: software only systems and 
flash based systems.  Software only systems are: GNAT Box Pro and GNAT
Box Light.  Flash based systems are: GB-100, GB-1000 and GB-Flash.  All
users of the commercial software only systems (GNAT Box Pro) have an
upgrade path to GB-Flash, (contact GTA or your reseller for pricing).
There is no flash solution for GNAT Box Light.

In each section below new features and changes apply to all versions
unless noted.
