mc head By ApexHosting

Another big update from the Mojang Headquarters creating a brand new home for the Nether’s newest residents….Piglins! Bastion remnants have been added and they look amazing with many cool new things to discover! Let us dive right in to the good stuff and see what’s new!


New Features in 20w16a


  • Added bastion remnants
  • Added ruined portals
  • Added chain blocks
  • Added a new music disc titled “Pigstep” by Lena Raine which can only be found in bastions


Bastion Remnants


What’s made of blackstone and full of Piglins and Hoglins? Bastion remnants!


  • ​Added 4 separate bastion remnant types: bridge, Hoglin stable, housing units, and treasure room
  • You can find these sizable structures in all biomes in the Nether except the treacherous ash-dusted towers of basalt deltas
  • Explore, loot, and conquer a bastion remnant to call it your home… but beware, Piglins don’t take kindly to intruders stealing their things


Ruined Portals


Shattered remains of ancient nether portals. Wonder who built them?​

  • They can be found in any overworld or nether biome
  • Some are hidden underground, under the sea, or buried in sand


Changes in 20w16a


  • Increased the amount of lava pools to make the deltas more “deltary”
  • The Piglin banner pattern can now be found in bastions


Technical Changes in 20w16a


  • Added a button in the GUI that generates a jigsaw structure starting from the jigsaw block, using given generation depth.
  • Expanded the max size per axis of Structure Blocks from 32 to 48
  • Added a JMX MBean to monitor dedicated server tick times


JMX Monitoring


It is now possible to monitor the server tick times though JMX.
The rationale for this is that JMX is a well known and supported monitoring technology with existing integrations and tools.

This enables server admins to hook alerts and graphing tools using ordinary JMX clients and dashboards.


Enabling JMX Monitoring


  • 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.
  • In order for enabling JMX on the Java runtime you also need to add a couple of JVM flags to the startup as documented here.


New discoveries await!


Can’t wait to check out the bastion remnants and what they have in store for us. The update is so massive but Mojang is showing no signs of slowing down and seems to be adding a slew of new things for us to find and discover. There’s tons of other bug fixes and changes as well we didn’t share so be sure to check out the changelog here. Get out there and enjoy the new update and pay our friends the piglins a visit!


Until next time,
