When you update a Topic Title, I’ve noticed that the link is updated, but the old URLs still work?
e.g
https://www.example.com/t/draft-today-was-interesting
still directs ultimately to the updated, despite the original URL being the above:
https://www.example.com/t/today-was-interesting
This is neat & cool, and clearly well thought out. How is that set up?
You are missing one very important bit of data in your URLs: the topic id 
That’s the only required information. We use it to fetch the topic in the database no matter what slug was used (we’ll even automatically redirect to the proper slug if it’s different from the one stored in the database)
Sorry was about to update the post 
Thanks for explanation
