Either its a new title or Funny Line but Bronns speech about how he loves people calling him my lord should counted.

His title is still just Ser Bronn of the Blackwater, right? He still hasn't gotten that castle or girl that Jaime promised.-nyan
His subordinates were all calling him my lord. Which he jokes to Jaime is new to him.-hindsight44
Also Jaime the person in charge of what rank Bronn is doesnt correct Bronn when he brings up he is a new lord he actually affirms it by saying, "you'll get used to it."-hindsight44
I can't find anything explicit for a new title. The wiki has some similar confusion:
"It is confusing why, at the beginning of the episode, Bronn remarks on how pleasant it is when soldiers call him "my lord" now - as if this is a new development. He is still just a landless knight, but was knighted at the beginning of Season 3 (knights are sometimes generically addressed as "my lord"). Later with Tyrion, Bronn remarks on how he actually hasn't gotten the full reward he wanted, of a castle and a marriage to a noblewoman so he can join the ranks of the nobility. In the novels by this point, Bronn has actually already married Lollys Stokeworth - who was introduced in Season 5, only for the Lannisters to call off the betrothal because they still needed Bronn's help. It's unclear if there was supposed to be some sort of deleted scene in Season 7 explaining that he recently has been allowed to marry Lollys, which was then cut for time, or if this is purely meant to refer to his status as a knight. Bryan Cogman did mention in passing that there were more Bronn scenes intended for previous episodes this season that were cut for time, which seems to support this somewhat."
So perhaps something did happen, but since they didn't get shown or mentioned explicitly I don't think we can count this.-nyan
