The National analysis Facility (NAF) at DESY has constantly been evolving since its inception in 2007. Starting as a distributed computing platform between the DESY sites in Hamburg and Zeuthen, it has been serving the German HEP users as well as international collaborators since as a experimentagnostic compute and data infrastructure. The technical implementations NAF have changed in a number of evolutionary steps over time to adapt to the changing requirements by its users as well as to the always changing technological landscape. While technological details have changed, central points to the NAF have been constant like data rather than plain compute being pivotal or like user support as a cornerstone. Followingly, we will describe the recent developments and updates in the NAF ecosystem. On the user side, further experiments have chosen the NAF as their computing platform and have build up their analyses pipelines ontop the NAF. On the operational side, effort has been made to further harden the security and increase monitoring and integration between compute and storage systems as complementary components of the NAF.
