Maybe I worded it incorrectly. The feature was released in that version. They just didn't mention it in the release statement they put out to their customers. I'm sure there's some changelog somewhere people can dig into where it says something like what you mentioned. Or it can just be under "Various small improvements" which they always add as a catch-all.

So I'm happy, I did the job and got paid. Everyone I worked with was happy. And the feature got released. It's was just a let down it didn't get mentioned at all, even though I put quite a lot of work into it.
