At this point in time none that I am aware of.
I was going to work on a solution to bring the current Wiki to the current Xoops but I haven't been able to revisit this at this time. I was discussing this with one of the developers and never followed up on it. I am currently working on trying to revamp the install script and have very limited time.
I want to help bring documentation back up to par but I just don't have the time right now. With the 2.6 Branch up and coming this will have to be revisited and revamped for 2.6 so you can expect it to be upgraded but likely not until after the module structure for 2.6 is set.
This site uses the Wiki module and it uses the later versions of xoops so I am unsure what issues have been dealt with.
