I never understood the importance given to release names. It’s all fine and dandy to have internal project names, but it features on apt sources files and whatnot. It’s confusing for the user, especially since they have a great numerical scheme. Just refer to the version and be done with it.
I totally agree. They have taken one of the best features of Ubuntu ( the meaningful and easy to understand versioning ) and thrown it in the garbage ).
I have no idea what the code name is for Ubuntu 18.04 or 26.04 but I can tell you when both of them were released.
