Today Bioware released patch 1.7.2 which brought back the Gree event for another two weeks. The Gree event ended about two weeks ago, much to the dismay of the player base. The short time period did not give players enough time to get all the rewards the event had to offer, although it was advertised as a reoccurring event. The Gree event also has a new reward, called the 'Blue Sphere' which carries on the techie look of the other Gree rewards.
The newest update also marks the new 'Shipment' of Cartel Packs in their store. This means that everything in the packs (including the more common items) will be completely different from their previous packs.
The last change made in this patch, is the new faction known as the Contraband Resale Corporation. This cooperation appears to be a lead in for the games upcoming expansion, Rise of the Hutt Cartel. For more information, the patch notes can be found here.
