Yes, I think it is. We are testing the update in the beta version now.
Correct me if I'm wrong, but in the iPhone app, it seems that for all "new" recipes, that there is no issue. However, for recipes that are older and with the BJCP 2008 guidelines. clicking on the style in the the 'general' tab causes the app to crash. That didn't happen in earlier testing, but it started about a week after the update(?).
I'm testing today, so let me know if there is something else happening, or if you have other issues with this.
