1) A TOS column has been added to /etc/shorewall/tcrules. This allows marking
based on the contents of the TOS field in the packet header.
2) Beginning with this release, the way in which packet marking in the
PREROUTING chain interracts with the 'track' option in /etc/shorewall/providers
has changed in two ways:
a) Packets *arriving* on a tracked interface are now passed to the PREROUTING
marking chain so that they may be marked with a mark other than the
'track' mark (the connection still retains the 'track' mark).
b) When HIGH_ROUTE_MARKS=Yes, you can still clear the mark on packets
in the PREROUTING chain (i.e., you can specify a mark value of zero).
Migration Considerations:
1) If you are upgrading from Shorewall 2.x, it is essential that you read

Use "shorewall restart" instead if you need to reprocess the
tcrules, tcdevices and tcclasses files.

New Features:
1) Shorewall has always been very noisy (lots of messages). No longer.
