Is that true? I haven't heard that before. Do you have a link?

Here's how they announced 24.04.0. It says LTS and doesn't mention anything about LTS coming in the .1 release: https://canonical.com/blog/canonical-releases-ubuntu-24-04-n...

I can't find any link, so I think I'm getting mixed up between what they consider LTS and when the upgrade tool starts prompting to upgrade. If you're on the 24.04 LTS, then you don't get prompted to upgrade until 26.04.1
