### GM Creates Open Source uProtocol and Invites Automakers to Adopt It: Revolutionizing Automotive Software Development.

General Motors (GM) recently announced its entry into the Eclipse Foundation. The Eclipse Foundation is a prominent open-source software foundation. In addition, GMC announced its contribution of “uProtocol” to facilitate
