Essentially, the lighting seems to be quite broken after the update, with un-smooth lighting, and more shadow bugs. This is without going into the editor or making any changes, just simply loading up the map to play like normal, and some very major obvious differences, as shown via screenshots below:
before - ">
after - ">
here's some more, where on custom blocks its even worse:

after - ">
Remember, this is just opening the map like normal to play. not going into editor, not changing anything about the map, nothing. These were all built and lighting computed well before the recent update.
