When I am reading Django’s release notes, sometimes I come across something where I want to know how (or why) it was implemented, read the reasoning behind it, stuff like that. Or maybe I come across something where I want to change how it works - for example this feature doesn’t work super well for me and I want to know what code to look at to know how I might change this. If the release notes would point to a ticket and/or a PR I could immediately see where to start.
I think it would be super helpful to link to the ticket and/or PR that implemented the feature. The patch notes already do this, so why not the big releases?
