Yes, it's still on it's way. The code in that post will still be included in the release, but we're working on one other issue that affects a minor amount of users. Once that is resolved, we'll be posting 3.1.2, and we expect (hope) it to be the final bug-fix release for 3.1 series.
If everything goes well, it will be available tomorrow afternoon. If not, I don't see it taking past Tuesday.
Sorry for the delay and inconvenience. Thanks for your patience!
