I've played 3.7 Tutorial, after a long layoff, and I've already found these:  I thought 3.7 was supposed to be a QoL update? #2 goes back at least to the Stone Age.

1. In the Tutorial, the City requirements are those of Synthetics.  But the player is and must be Terran. Update: Incorrect.
2. On the main menu screen, the Manual button pulls up Manual version 1.03, which has been obsolete since the Stone Age.  I don't know where it's getting it, but the current manual is already on the player's computer.  Why not use it, or at least point it out? Update: Fixed in 3.8.
3. Same screen, the Wiki button takes you not to the wiki but to a page trying to sell you the game you obviously already have.  Huh??  Update: Fixed in 3.8.
4. On the Steam launcher menu, top right dropdown, the Game Guide button is broken.  It goes nowhere.  Update:  Fixed.  Now it goes the Wiki.  Perhaps it should go to the Manual, but at least the link is no longer broken.
5. I don't know if this qualifies as a bug, but the Tutorial scenario in 3.7 is a pale shadow of that in 2.33.  Colonizing Precipice is a mere distraction.  And your friendly neighborhood Iconian may be your biggest hinderance.  Fortunately, the Drenghin is no threat at all; he never even leaves orbit. This gives the player time to work around the effects of Bug #1.  But a Tutorial shouldn't take 300 turns to complete.

More as I discover them.
