Counter-Strike: Global Offensive just got a small update for its maps yesterday. The update tweaked the Swamp, Mutiny, and Cache maps. CS:GO's performance on the Swamp and Mutiny maps was also improved. Ambiance sounds are now more quiet and invisible water splashes are fixed. A new radar has been added to the Swamp map and gaps in the wood fence at A-long (T side) are removed.
Clipping issues on Mutiny are fixed and foliage on the 'A site' wall is removed. Part of the wall in bombsite A is lowered and environment lighting is improved. A lot of other changes were made to the three maps, and two bugs were also resolved. You can learn all about them from the official CS:GO blog post. They are mentioned below as well.
