I’ve just upgraded my Ember app to 3.12.0 using `ember-cli-upgrade` and everything worked fine. The `package.json` file shows the ember-cli version as `~3.12.0` and `package-lock.json` reflects `3.12.0`.

If I run `ember --version` the result is `ember-cli: 3.12.1`.

However, Ember Inspector reflects the Ember version as 3.16.0. Why does this discrepancy exist and what does it mean exactly?

This is as expected! `ember-source` is the actual source for the browser-side JavaScript (where `@ember/service` and all the other imports come from), while `ember-cli` is the command line tool we use to _build_ Ember apps. So:

- The version of Ember shown by the Inspector corresponds to the version for `ember-source` in your `package.json` file.
- The `ember` command is supplied by `ember-cli`, so that you don’t have to type `ember-cli serve`, just `ember serve`. (npm packages can have “binaries” with any old name; they don’t have to match the name of the package.)

If you check your `package.json`, you’ll probably see something like `"ember-source": "~3.16.0"`!

Correct! `package-lock.json` shows version `3.16.0` for `ember-source`. Thank you.
