I don't know of any other changes here except for the announcement, but I found that change to be extremely significant. In fact, that was one thing that caused me to leave. By using that announcement, they can now claim that they never "disfellowshipped" the person, even though the congregation will still use that term and will still be expected to enforce it by shunning. If legal trouble arises, I would expect that they can now claim "we never disfellowshipped that individual. they merely ceased to be a member of Jehovah's Witnesses"
Meanwhile, the congregation will still refer to him/her as "disfellowshipped" and will still enforce the shunning that goes with the term. I was active at the time I first heard the announcement and it struck me as very slippery.
