I'm just wondering if october cms will also apply new features of laravel 5.3 or 5.4?
October has been taking the no-breaking-updates approach ever since. It is highly unlikely they will upgrade to Laravel 5.3 or 5.4 for no reason, since October runs perfectly well on 5.1 LTS now. They might consider an upgrade when a new LTS version becomes available.
As it seems that Laravel has moved away from using LTS releases; if there is a specific feature that you would like ported from newer versions of Laravel, bring it up on Github and we'll see what we can do.
October has upgraded to Laravel 5.5 LTS as of Build 420. Update now to get all the great new goodies :)
