I do appologize if this is a dup i was not able to find anything on this issue.
Between the release of the new windlight in the firstlooks before the "There are stripes in the sky" problem I know the environment/sky was rendered in a sphere (can be seen in wireframe mode), but once the stripes bug happend it seemed instead of people just simply fixing it by the settings they complained about it and now the environment was reverted back to the basic box it was before windlight, you can even see the edges durring parts of the day, do appologize I should have probably posted this when i noticed this durring update changes, even if there were some rendering problems people could have easily fixed them via settings, I did not know anyone that was not able to fix them personaly. The Sphericel Render was SO much better then the box it currently is once more.
