RL Environment - OpenAI Gym Taxi-v2 vs Taxi-v3

Question

Gym Taxi-v2 is deprecated. My implementation of Q-learning still works with Taxi-v3 but for some reason, env.render() shows the wrong taxi position at each step.

Anyway, apart from an added wall, what are the differences between Taxi-v2 v Taxi-v3?
