I didn't see the subject of compatibility between versions addressed yet on this thread, so....

  1. Will a player using 9a be able to net-play against a player using 9b?
  2. Will going to 9b require converting the game data to a new format? If so, will that be reversible, or will upgrading be a one-way operation?
  3. Will custom reports (et cetera) for 9a continue to work with 9b, or will they need to be rewritten?

I won't be upset by any answers to these. I'd just like to know what to expect, to manage expectations and the upgrade path for the people in my league.
