New things:

• Non-blinking cursor (ref #17). Also note that cursor blinking is now configured through guicursor (see :h guicursor and h gnvim-cursor-blinking).
• Visual indicator for modified buffers in tabs (ref #52)
• Hide completion item icons if all of them are unknown (ref #50

Also, there is now a gitter room for gnvim! Lets see if it gains any traction.
