1.6 will include a new launcher. It's very important to keep your 1.5 launcher installed until we give you the all clear. Yes, we're aware that the new launcher supports old versions, but we want to ensure you are still able to play. The wastelands will be reset upon our 1.6 release as well, so be prepared with anything you want saved and get it back to town. Whenever Mojang releases a new version of Minecraft you will be asked if you want to update when launching the game. We don't really know when these releases are coming so they could be at any moment. If you upgrade your game you will NOT be able to play on any EMC server until we finish upgrading. I say again DO NOT UPDATE if you want to play on EMC. Once a new update comes out we then have to wait for the new server version to come out. The talented Bukkit and Spigot teams then has to fix the server so it is actually usable. At this point we get it and we have to integrate it into the EMC platform. Once an update comes out we go into overdrive and our goal is to get out the update in a stable place ASAP.
