I would really like op2hacker or LeV to write down every single change they make to each version of Op2.
For the sake of transparency, maintain a "changelog.txt" with dates so we can keep track down any changes made to the game over time. No matter how light the change might be, it is relevant.
Since I don't see any changelog in the op2 package, I urge you to adopt this methodology, so anyone can know exactly what is changing in the game, and obviously what has changed since the last release from Sierra.
