This file describes the upgrade procedure from various versions of Barefoot,
if any.

*** Upgrading from 1.4.0 to 1.4.1

 o Session limits are now by default inherited by from lower level ACL-rules.
   To keep the old behaviour, "session.inheritable: no" must be added to
   each rule using session limits.

 o The syntax for maxsessions has changed from "maxsessions: <value>"
   to "session.max: <value>".  

 o The default timeout for tcp i/o (timeout.io.tcp) has been changed from
   84000 to 0.  0 means use the kernels default, which in most cases will
   mean no timeout. 

   The old behaviour can be restored by adding the following line to 
   the server configuration file:
      timeout.io.tcp: 84000
