State to to after update .46

What does this mean?

Check out the breaking changes in the Release notes.

Breaking change note 1: An automation state trigger that had only from or to (but not both) used to be triggered whenever state attributes changed, even if the actual from/to state remained the same. This has been changed so that from and to will only match when the state actually changes from or to the specified state.

Breaking change note 2: The automation state trigger used to allow state as an alias for to. This naming was a bit confusing and state has now been deprecated.
