Minecraft Snapshot 20w16a

Bastion remnants and remnants of Bastion, or "home sweet home" as Piglins would call them they are finally here! This snapshot introduces the home of the Piglins. If you look around the world, you may also come across ruins of some old portals.

New Features in 20w16a

Bastion remains added - Portals added ruined Chain blocks added. The new music disc called "Pigstep" by Lena Raine, which can only be found in bastions

- Added four bastion remnants: bridge and Hoglin stables with housing units, as well as a treasure room. These structures are located in all biomes of the Nether with the exception of the treacherous ash towers of basalt Deltas. Explore, loot and conquer an abandoned bastion to claim it your home... but beware, Piglins will not tolerate the theft of their possessions by intruders.

Ruined Portals

They can be found in any nether or overworld. Some are hidden beneath the sea and others in the sand.

Changes in 20w16a

- Increased the number of lava pools to make the deltas more "deltary" - The Piglin banner pattern is now visible in bastions

Technical Changes in 20w16a

- Added a button to the GUI that generates an jigsaw pattern starting from the jigsaw blocks, with the given depth of generation. - Expanded the max size of the axis of Structure Blocks from 32 to 48 - Included a JMX MBean to monitor dedicated server tick times

JMX Monitoring

It is now possible to monitor server's tick times using JMX. The reason for this is that JMX is a well-known and well-supported monitoring technology, which is paired with existing integrations and tools.

Administrators of servers can connect alerts and graphing tools to ordinary JMX clients or dashboards.

- A new flag enable-jmx-monitoring has been added to the server.properties file which if set to true will expose an MBean with the Object name net.minecraft.server:type=Server and two attributes averageTickTime and tickTimes exposing the tick times in milliseconds. You will be required to add JVM flags to your start-up in order to enable JMX on Java runtime.
