A new draw style, Joint, has been added to the Draw Style menu in the Joint options.
A walkthrough of different Joint Draw Styles
This new draw style adds to the previous three types: Bone, Multi-child as Bone, and Box.
When you choose Joint from the Draw Style menu, only a sphere displays without the connecting bone. (If you choose Bone, a sphere and a cone is shown.)
The Joint draw style is useful for working with rigs that contain multiple child joints in a small area, for example, facial rigs, where it can be difficult to view joint influences.
