Zen-Cart v1.3.8 and phpBB v???

I have specifically turned to Zen-Cart due to the phpBB Integration but as many others have posted it is not as simple to get the two working error free. I am sure this feature was not released with errors and believe that this maybe due to incompatable versions eg. Zen-Cart makes changes and phpBB makes changes then the 2 don't link up anymore?

I am writing to ask where can I find a list of compatible versions eg.

Zen-Cart v1.3.8 and :

phpBB 1.0 - 100% supported
phpBB 1.1 - 100% supported
phpBB 2.0 - 85% requires patch installed and modify config.php
phpBB 2.1 - 90% modify config.php
phpBB 3.0 - 100% supported
etc...

obviously this is an example, however if this is available it may assist in minimising all the questions like myself have regarding all the errors.

If I recall correctly, the phpBB support in v1.3.8 was last updated back around v1.3.5, and was written to work with phpBB 2.0, which I think is what was current at that time.

There is a patch discussion on the forum here somewhere about phpBB3 and a few coding changes that were required to make it work with phpBB3. Some folks have met with some success by using it.
