The News app says it's version 4.1.1. It's part of a shipping release version of macOS. I don't know why any regular user should come to the conclusion that this is some sort of technical preview. Why wouldn't they think that it's simply terrible software?
Absolutely. I just think these apps should never have shipped as part of an OS release. They are demo apps for the Marzipan technology and should have shipped as part of an SDK.
Yeah that or just label them as beta to set expectations. Unfortunately, Google has ruined the term beta for users. Maybe put them in a folder called “Prerelease”.
