Editor’s Note: This post incorrectly listed 20W16A as 20W19A, the Minecraft Snapshot 20W19A patch notes can be found here.
Mojang has been working steadily on new Nether-based content for coming updates, but that has not stopped their work on other minor content within the game. And just today the developers have issued a new Snapshot for testing some minor content updates and bug fixes. The newest Snapshot, Minecraft Snapshot 20W16A brings new content to the game and some minor changes.
A few new gameplay additions add a few new items that players may want to explore. The new Bastion content leads the charge, adding new units to the roster of NPCs and enemies in the game, as well as some new structures and building tools based on the faction. Players exploring this content will find new houses, bridges and other structures with this new flavor within Remnant areas.
The patch for the new Snapshot also includes minor bug fixes for issues affecting biome load and generation, as well as some backend problems affecting server stability.
You can find the full notes from Minecraft Snapshot 20W16A below:
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
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
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
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.
