First off, We've answered this question many times. We will update when the plugins we use are updated and we make sure that things are stable and won't break anything specific to our server.
Anyone can go and grab updated plugins, start a server, and claim that it's ready. There is FAR MORE work than just grabbing plugins to ensure that we do not lose data, negatively impact our playerbase, and ensure that many of our entirely custom in-house plugins and applications work with new plugins.
Furthermore, we have never, and will never put a list of plugins that we use on the server - no matter how much people want to "help". Anyone can watch a page and see when a plugin is updated. It takes far more work to ensure that it works for us.
We've been doing this for many years with our server, and we know when we are ready to update.
