The second release candidate for BGMP 1.9.3 is now available. This release fixes a few bugs found in RC1. I'm not sure whether the JSON line break bug is fixed, though, so I need some help testing this.
If you'd like to try it out, just download and install it. If you notice any problems, give detailed feedback here and then downgrade to 1.8 until they're fixed.
If you don't notice any problems, please leave a quick note here so that I know it's working for others.
I've setup an email list to notify everyone when new RCs are available in the future. That way you'll have time to test it out on your staging server, and we can work out any bugs before the official release.
