Side note:
In the early days of the Discourse AI there was the ability to have the AI generate a new title for the topic based on the existing text. I used this often as a category moderator when they titles ran long, think wrapped around when viewing in a list. Then the way to do this vanished; I may have missed how it was supposed to be done but now it is back with this.
As a category moderator one can not edit a post and the AI option is next to the title for changing.
Was looking for that in the announcement, might be worth a mention. 
The following post contains some screenshots.
