Questions about 1.9.1

When was Minecraft 1.9.1 released?

Minecraft: Java Edition 1.9.1 was released on March 30, 2016.

What Java version does a Minecraft 1.9.1 server need?

Java 8. On FadeHost the server starts with the right Java for its Minecraft version on its own, so there is nothing to install or switch.

What did Minecraft 1.9.1 change?

1.9.1 added armour toughness and several combat tweaks, then was pulled the same day over a major multiplayer bug. 1.9.2 replaced it within hours.

Can players on another version join a 1.9.1 server?

Only players on 1.9.1 itself: its network protocol (108) is its own. A Paper server can let other versions in with plugins such as ViaVersion and ViaBackwards.

Can I update my world to Minecraft 1.9.1?

Yes. Take a backup, switch the server to 1.9.1 and start it: the world is converted on the first boot. A world opened in 1.9.1 cannot be opened in an older version again, so keep the backup until you are sure.

How do I start a Minecraft 1.9.1 server?

Create a server on FadeHost and pick 1.9.1 in the software list: Spigot and Vanilla are there for this version. It is online in about a minute. The free tier runs a 2 GB server at no cost, and a paid server is sized to the RAM you need.
