Help me understand GTS and LATEST

[aravindk]

I struggle to understand the difference between gts and latest.
The official website (https://projectbluefin.io/) only provides gts version ISOs. Why developers prefer gts over latest?
Is latest something like a beta?

latest is based on the latest Fedora version, so right now it’s 40. gts is based on (latest)-1, so right now it’s 39. In the future, when Fedora 41 is released, latest will be upgraded to 41, whereas gts will be upgraded to 40.

It’s intended to ensure gts users experience slower updates and more tested, stable+solid system by not being on the most recent Fedora version. So if you prefer slower and/or less updates, but don’t mind having slightly “older” system packages, gts would be the better choice. On the other hand, if you prefer to have newer packages and get updates as soon as they come out following Fedora 40, you would want to use latest instead.

Reinstall Required?

You won’t need to reinstall again, once you’ve set it to gts you’ll stay on whatever the -1 release of Fedora is automatically. I set all my work machines on gts. So you’ll get upgraded to F39 when F40 comes out. What happens is on release day we update the latest and gts tags to point to the new values and then our computers will all follow along.
