When checking for instance the "latest submissions", you see the above picture on the scripts and tutorials that works only with Resistance.
Inside the snippits and tutorials it is clearly stated "Recommended for version (#.##)"
That means version #.## and above.
All submissions doesn't have this, so there's a lot of work between handling new submissions, updating outdated ones, and fixing the old ones. The one's who are still not clearly marked, are not often used, so I'd say it's not a big problem.
If you have any particular scripts or tutorials in mind, send me a PM with the names (preferably links) of them, and I'll sort it.
