Zowe was announced at SHARE in St. Louis 08/14/2018. I'm convince this will be the face of the mainframe in the very near future. I urge anyone interested in the future of the mainframe to check it out.
I see ZOWE is mainly backed by IBM and CA as per
"Zowe Leadership Committee".
My prediction is this will change as people start playing around with it and developers build on the platform.
But made that observation as well. Being open source the community can take it where it will. I think it represents a paradigm change that the community will run with. That being said I'm curious how the governance will evolve.
