How can I see the history of a package in the Npm registry?
In particular, I want to know when https://npmjs.org/package/npm version 1.1.2 was released.
You could do npm view npm there are some options you can find at https://docs.npmjs.com/cli/view
npm view npm
e.g. npm view npm@1.1.2 time
npm view npm@1.1.2 time
