You can just play as you normally do, and if you encounter an issue you will notice. If you look at the bug report section you will notice that the vast majority of reports are not about things changed that day, but rather on any other aspect of the game.
Indeed knowing what changed is an extra help that can let you focus on those aspects first, that's why we try to deliver all possible info as soon as possible. Sometimes it is just not quick enough and we're working on improving that
Thanks for your strong interest in helping us finding and reporting game bugs, we really appreciate you want to help this much!
