Upgrading to latest ROS "destroy" some firewall rules

Hello,

All my configs have 4 rules:
accept for Connection State = established
accept for Connection State = related
(for input and forward chains respectively)

after upgrade to latest ROS (for example 6.33.1 → 6.37.1), I discovered that these rules now without any “Connection State” value!
now its simply “accept all input” and “accept all forward”!
this is a serious security breach!

The same situation. After upgrade old ROS (6.34 and less) to 6.37.1 - related and established box’s were unchecked.
