The base OS and the installed 3rd party software (ports/packages) are on different release models.
The base is either stable/LTS (~5 years support) or rolling if you track -CURRENT.
For the 3rd party software it is either rolling or stable in short lived quarterly branches.
Most server side software is usually pretty up to date but some desktop-related tools can be outdated for a while. You might want to take a look at [0] and especially at the commit history of some fairly popular desktops like Gnome3 [1] or KDE5 [2]. They got updated recently but it took quite a while.

P.S when I say lagging behind I don't mean the server things but rather on the developer side.
