"Official changes" is word for word the information the developers release with the game updates. We can only try and guess from their ambiguity at times or their Russiona-English attempt at translation to work out what they mean. eg: Updated Bank Interface took a while to realise they didn't mean the Bank but they real-money interface to purchase in-game currency. They have been tending to announce "New Events" a few days before the new event started, and a game-event can start 1-2 days before the actual-event, so an event running over May 9 (starting maybe May 8?) would seem to be in line with an announcement now.
