Is there a description for new version's new symbols?

[Evreka]

I rarely play new edition. In part because I prefer the old graphics by about a mile any day, in part because I mostly know how all wonders work, and need to spend very little time figuring out what things do. However, the latter could be helped a lot for the new version. if it was a description available somewhere of the new Wonder stages and any other potential changes. Where can I find this info? The rules on the game page only showss the old edition, unless I miss something?

You can hover over the stages to see the detailed description.

The new rulebook can be found here:

I've also made a video with all the changes here:
