wizard spell availability on green?

[Firepuff]

The p1999 wiki only states which spells came with which expansion, but several patches that were not expansion related, also introduced spells/new ways to acquire them.

Is there an easily understandable overview where I can see, when to look for/attempt to research, certain spells?

Or do I need to peruse all the patches notes in waybackmachine to get my answer?
