Welcome in the new PocketMine-MP update host, update.pmmp.io. What is this? update.pmmp.io replaces the old PocketMine-MP updater API at pocketmine.net. Servers can now use this to check for PocketMine-MP updates and will warn users if there is an update available. How do I use it? If you're setting up a new server as of the latest commits, you don't need to do anything. If you're running an existing server and would like to be notified of updates, open up your server's `pocketmine.yml` and change the property `auto-updater.host` to `update.pmmp.io`. Make sure you have your auto-update config enabled too. At the moment you probably want to set your target channel to `development` to get notified of latest builds. More on update channels at a later date when it is relevant. How does it work? It doesn't do anything fancy yet. If you are running a server from a phar, you'll be notified when there is a new build available from Jenkins. Note that when running from source, you will not be notified of updates. (The name "auto updater" is a little misleading to be honest, it doesn't actually update anything yet... that'll come in the future).
I probably should have mentioned there's a crashy issue with the updater up until 2 days ago. If your server crashes when trying to fetch update data please update your server manually and try again.
