I can't say this with 100% confidence, but it happily appears that using Siri to create a calendar event that mentions someone's name (e.g., Dinner with Tom) no longer automatically adds that person as an invitee to the event. Siri will ask you to select Tom's email address, but it doesn't seem to actually do anything with it, such as add Tom as an invitee on the event. For those of us syncing to Google Calendar, means that Tom will not accidentally be sent an unwanted invitation. (I say "unwanted," because Siri also used to send the invitation if the title of the event was "Dinner about Tom," or "Dinner about robbing Tom", which could be awkward for Tom to be invited to attend.) Anyone noticing the same thing? I'm so gun shy about it at this point that I still can't quite get myself to use Siri for calendar entries. But maybe if someone else confirms that they are seeing the same thing consistently.
