Why i upgrade to the latest phpbb ?

Phpbb had many holes and have seen many forums hacked , that is why i upgrade to the latest phpbb whenever is released a new version ASAP.
I think is the same with punbb ,
One way to react is to contribute with secure patches (and code review)

There are other options in future (to test ) for securing php install hardened php
