The Test Server had a small patch yesterday to add the improved repair functions that did not make it into yesterdays patch to live.
Along with the above changes they have also added data for what seems like some new weapons skins, which we can only speculate will either be exclusive to the Item Exchange like the Wildstyle skins are, or preperation for a new crate.
So far they have only added the item data and not the corresponding skin data, so we have no details of rarity level yet.
