W3c Webdriver vs Json Wire Protocol

Hi,

I am using json wire protocol for driving selenium web driver. Now the Wire protocol is saying the it's obsolete and new one is W3C.
I noticed few api changes also, in the calls.

But what is the significant change in W3C webdriver in comparision to jsonWire. Do I need to move to the latest one.

Kindly clarify, or send the link which shows enhancements/differences.


Thanks
Sushant
