Minor issue 6000.3.1f1 is still an LTS, yet because there is a newer LTS version out it loses the LTS label, I just think this is wrong, if you want to signify this is no longer the latest LTS or a newer update is out why not just put [Outdated] label on it or something similar alongside the LTS label,
For the most part that “long term support” means Unity is publishing new releases. You aren’t really on “long term support” if you stick to the second release version (1f1) - you’re effectively passing on that support if you don’t frequently update. In that sense it does make sense to label only the latest release as LTS.
Though I can’t say if that is really the intention here.
yeah well the logic doesn’t work if a version 6000.0.64f1 from like a year+ ago still has the LTS label on does it.
I think it’s wrong, the 6000.3* versions should have LTS, maybe [Latest] label for newest version out, just as 6000.0 should have as they are LTS versions, and lets be honest some LTS versions are less buggy than others. 6000.4.* no LTS label because it’s not same with 6000.5, etc
That exact version was released sometime in the past four weeks. 
6000.0.23f1 was the first LTS which I think was released in October 2024.
They start buggy and progressively improve thanks to those releases.
When a user on 6000.0.23f1 runs into an issue, and plays the “long term support” card, the user gets that support by updating to 6000.0.64f1.
Those used to be called “teach stream” releases (eg 2022.1 and 2022.2) but are now called “update” releases considered production ready. More details in the FAQ here.
For Unity 6 the LTS is carried by 6.0 and 6.3 currently, and I think the plan is for 6.7 to be the next LTS.
The in-between “update” versions typically only get 10-20 releases, and typically few to no further releases once the next higher version is released.
When Unity versions start out as “alpha” and then “beta” the first non-beta is kind of “gamma”
“That exact version was released sometime in the past four weeks. ”
Except 6000.0.65f1 is the latest of that LTS version… yet in the versions for a project a older LTS version that is no longer the latest LTS of that release still has the label.. make it make sense.
“They start buggy and progressively improve thanks to those releases.”
Until there is a regression and or new bug and then it’s back to older version of that LTS release, you make it sound like newest one is always the better one but in reality it is not.
My point still stands the issue is LTS label being removed from an LTS version release when it is still an LTS version, if you want to signify it is no longer the latest LTS of that LTS release than find another label to tag on or remove when a version is no longer the latest or outdated lts.
