ToME: the Tales of Maj'Eyal

Hello,
I am a new player and many guides and strategies are quite dated from version 1.1 to the current one 1.5.5. I have noticed while playing that many talents,trees, classes etc are changed from older postings etc. I cannot find a repository for the changes so I can understand what is out of date and what has changed.

There are random links to some versions but it is not very easy to find them.

Any help is appreciated thanks

https://te4.org/news will be the place to find all version changelog in the release post.
Alternatively you can google it.
The maintainance of wiki is poor.
