JSON returned is different when fetching in browser and by javascript

[Lennart Borgman]

If I fetch this URL by directly pasting it in the browswer's address field (Chrome) I get a different JSON returned than if I use XMLHttpRequest:

    https://api.zotero.org/groups/56508/items/3B6TR25A?format=atom&content=json

The "itemKey" field is for example missing in the browser but is present in the javascript return value.

It's API v1 vs. v2. Version 1 is still the default, and you have to pass
an HTTP header to get v2. For testing, cURL is generally the best option.

We're adding a query parameter in v3 as an alternative way to control
the version.

Thanks Dan, I just remembered and was going to tell that. Sorry for disturbing.
