...Meaning the stuff that is in there, will programs, drivers, KDE be updated when new versions are released
All programs in the Official package source
+ mirror(s) are maintained by the developers of Pardus.
When new versions of programs for this version of Pardus are released (after testing), they will be offered as an update through Package Manager.
This means that the official repp of Pardus is a dynamic repo.
Pardus has, in principal, a so called rolling release system.
This means that whenever it's possible, the transfer from the "old" Pardus to the new version will be through updates and the user only has to apply all updates to get the new Pardus.
If this isn't possible, because of software reasons, they will offer an Upgrade Manager sometime after the release of the new version of Pardus.
With this Upgrade Manager, made available in the software repo of the "old" Pardus, the user can upgrade to the new Pardus.
And as the manpower of Pardus isn't unlimited, it can take some time for this Upgrade Manager to appear in the software repo of the "old" Pardus.
At this moment they are (I think) still busy with fixing blocking bugs and filling the repo of the new Pardus.
And the best summary for Additional (non-official) package source
in this Post
On Pardususer.de we are actually 5 people creating packages. Three german guys, one dutch man and one turkish guy.
My knowledge about package building is limited, but everybody is trying to help. Its a good teamwork.
When you have this source in your Package Manager, there updates will also go through your Package Manager.
