Caught the back end of a Deal or No Deal episode just and while I knew they'd chopped out the viewer end-game results with the blue boxes, Challenge seem to have started doing chopping out "see you tomorrow" references on it for some reason covering it with an audience cutaway.
Challenge know there is the possibility they will never air these shows in order, and also if they are airing back to back blocks of the show, "see you tomorrow" doesn't help, when in fact viewers will be seeing the next edition in two minutes time.
On a side note, I remember the big change with Deal or No Deal around 2014. Up until then, Noel would always state the day the show was airing, from around 2015 he stopped. Also it was around 2015 they abandoned all of their little specials they would do around Easter, Banker's Birthday, Summer Special, Halloween etc. They did put together the odd special, but those ones were dumped in 2015 which did signal the end of the show for me.
