For online the duration of the post-whistle time has been reduced, and a few gameplay exploits have been reduced.
For offline play once you have the update it will be applied automatically if you still have the Tuning Set option set to Latest (which is the default). Otherwise you can set it to Latest or V1.03. If don't like the changes or prefer to finish your current Dynasties/Be A Pro with a previous tuning version you can also change it (under Gameplay Settings/General). V1.02 is what you'd be using right now if you have the previous update and are set to Latest.
For online play everyone uses the latest tuning update.
There are quite a few changes involved in this update so we'll be watching closely to see how things play out and make any adjustments that are necessary.
More detailed notes on the changes should be posted on the NHL forums/blogs tomorrow. I'll make sure they end up here too."
