Minecraft 1.9 was released this morning (yay!). Here's some answers to common questions:
When will the server be running 1.9?
Spigot is planning to release their 1.9 compatible version today or tomorrow, and as soon as that happens I'll test our plugin configuration with the new build. As we have kept the number of plugins we use minimal, I'm hoping there are not any incompatibilities. If there aren't any, I'll push 1.9 out immediately. If there are, we will have to wait for the plugin developers to update their plugins.
Will the server map reset?
No - we just reset the map as part of Obsidian 2.0. We will be resetting the end (as there are many changes there), but I don't believe anybody has visited it yet on the new map.
Will the world border be increased?
Yes - there are changes in the overworld generation, so the world border will be expanded.
Any other questions?
Ask them on this thread! I'll post an announcement when the 1.9 switch takes place officially.
