The SketchUp team unveiled the 2014 version this morning! There are lots of fixes with this version but the most interesting change is a revised and improved 3D Warehouse. The look of the warehouse has improved immensely, but the model collection is also better. There is now a products catalog with better organization. There is also an ability to showcase your models with an orbit and zoom feature over the web using a WebGL browser.

If you have a Pro version with a maintenance release, the upgrade to 2014 is free and readily available. Their blog post about getting on the maintenance program can explain any further questions you may have about upgrading.
