Hi Jaga,
I haven't had the time to update to 1.7 yet. I'd love to, but as I
mentioned I haven't been doing much GWT lately. The main pain point of
upgrading will be the way I modified the Serialization code to clean
out Hibernate objects. That's a fragile point of failure and I'd
probably recommend looking at Gilead instead, since that seems to be
how most people are solving that problem today.
