So as of today the latest "stable" release of Debian is a month old.
By contrast the last stable release of Fedora is Fedora 43, released on October 28, 2025 which four months old at this point.
Really once you get software that works all of this is pointless anyway, you have working software and you update once every year or so, or when you find you need to.
When you "need" to update is so personal that it cannot be predicted, but your FUD about Debian being universally old and outdated is clearly misleading at best and deliberately misleading at worst.
