I've been running multiple tests using Minecraft 1.9 since its release, stress-testing the performance of the game, evaluating and updating plugins, that sort of stuff. While some of you have been having fun playing on Nena, our temporary 1.9 server, many are looking forward for the entire network to jump over to the new version.

Unfortunately, there are several issues still happening in multiplayer that are major enough to prevent us from moving forward. Most notably, riding minecarts tends to freeze you in such a way that you can't exit the cart or move forward anymore. The only way out is to kill yourself somehow, which isn't exactly fun when you want to keep your inventory! There are also several other problems that arise, like mobs (friendly and hostile) freezing into position and becoming unkillable until the server is restarted; and item drops not behaving properly, making item trading a huge hassle. That's why we're not switching to 1.9 today. My entire code and set of plugins is ready, so we're now depending on other people (Mojang / Spigot / plugin authors) to fix this.

At this point, I don't know when we'll be ready for the upgrade, but it's not going to happen for a week at the very least. More as it comes!
