We carry out server updates. However, if you do not want to wait, you can also update your Minecraft server yourself. To do so, please go to the official Minecraft site. Currently this is www.Minecraft.net. Go to the download section there (http://www.minecraft.net/download.jsp) and download the file minecraft_server.jar.

Then upload this file to the game server FTP (ftp://upload.4netplayers.de) to the root directory of the configuration.

Following a restart, the server will then be running the new version :)

If Bukkit is active in the web interface, this must be deactivated! 

If you update your server using this method, you will need to do this for every server update from now on!
