I just upgraded to the latest patch (3.361) and noticed something that had not happened before the upgrade. I had a read-only text field with a default value displaying the price of a training course. The field was set under Advanced Setting to be hidden until forced visible by another event. Prior to the upgrade, this worked fine. Post-upgrade though, when the field is forced visible by the question event, it comes up, it's blank. If I un-check the Advanced Option to hide until forced visible - so that the field is fully visible, the value re-appears.
Since I'm not doing any calculations on that field, I was able to changed it to a html field and keep going - but it would be nice to be able to have the textbox back again.
