Well, this site (datamost.com) is one of the public, federated servers on the Pump.io network.

It receives updates when the server software is updated, which happened a few days ago, with the upgrade to Pump.io 4.0.0.

But Pump.io is a mix of many components which are updated independently, like the Pumpa and Dianara desktop clients, or the NavierStokes "networking bridge" utility, for instance.

What exactly are you expecting?
