Description
Comparing images in 1.5.2 and 2.0.0b3 shows a reasonably large change. Originally, I thought the sampling was just different and it was intended, but closer inspection seems to indicate that it might actually be a small shift in the extent.
I don't have a simple example, but here are two from Cartopy to illustrate what I mean:
If you switch between them, you can see that 2.0.0b3 seems higher, though I think it's actually the right edge that's a bit further out.
A better example is:
It's clear on this one that the image is just a bit wider in 2.0.0b3 vs 1.5.2.
The code for these two plots is global_map.py and test_regional_projected.
It looks like one edge is off-by-one or something, but it's also possible that the transforms were just corrected in some way.
