I was playing around a bit with Fiddler to capture traffic from the Stack Exchange iOS app. To my surprise, it uses version 2.3 of the Stack Exchange API:

enter image description here

I noticed here that it has some extra functions compared to the current release (v2.2), and that it wasn't documented yet. However, that answer is one-and-a-half year old; any updates on this topic? Or will this keep on being an unofficial release, only released to support some additional features for the mobile app, which as we know isn't actively developed anymore?

  • @double-beep my answer there got a [status-review], so I'm waiting for an official response here. Not all 2.3 API methods have been documented, it seems.

Note that version 2.3 has been around since at least Aug 28, 2015 (Date of that answer).

I could have sworn that one of the SE guys said they weren't going to document it, but can't find a reference for that.

Anyway, in Jan 2017 the (former) API developer, Brian Nickel, said:

There's no timeline yet for new features (and API backing them), just focused getting the app working. Still, there are some smaller changes like submitting suggested edits, tag preferences, and can_ fields ready for (API) 2.3 when I get the app shipped.

Given that that was before API devs got switched to "Developer Affinity & Growth" (DAG), per the answer you linked, it may be a while before we can see anything official on the next API release...
