Actually, it's just a labelling change. Season 2A and Season 2B got relabelled as Season 2 and Season 3, and Season 3A and Season 3B got relabelled as Season 4 and Season 5.

So under the new labelling scheme, we just finished Season 2 in January, Season 3 starts in the summer, and they're currently recording episodes for Season 4 and probably already storyboarding Season 5.
