Well (again) a small but subjectively unenjoyable change to graphics, note the shadowing on the edge. Now is that a bug or an intended change?
Yeah I should perhaps have added a marking. My bad. It is better visible in other arrangements, but thats the best 1.8 screenshot reference I have available right now. Ambient Occlusion is the shadowing on the edges. They had the issue already with the 1.7 or 1.8 Patch, and toned it down afterwards. It is again increased, even though not as bad as it was back then.
