Minecraft 1.19.1 Pre-Release 4

A Minecraft Java Pre-Release

Hi everyone,  

Before we jump into today's pre-release, we would like to take a moment and dedicate some thoughts to a person who over the years has made an incredible impact on the Minecraft community and touched the lives of many. Technoblade became synonymous with a source of good – a positive force that time and time again made many, many people happy and someone we are proud to have as part of our giant family.

Minecraft is its community, which is why it should come as no surprise that so many of us mourn the loss of him, with tributes and love pouring in from across the world.

On behalf of the Java Team – thank you Technoblade for the memories, for all the fun and the laughter. You will be dearly missed. Our thoughts are with your family and friends.


Regarding 1.19.1: We still have a number of fixes in the pipeline, set for another pre-release in the near future. After that, once everything is tested and verified, we'll be aiming for a release candidate.

Edit: We've now released 1.19.1 pre-release 4. This pre-release fixes an exploit found regarding contextual chat evidence when creating a Player Report.

Technical changes in 1.19.1 Pre-Release 4

  • Custom servers can hide player chat messages from display via a new network packet
    • This does not delete player chat messages from chat logs
  • Insecure chat messages logged in the server are prefixed with a [Not Secure] tag
  • The order of chat messages are now cryptographically verified
    • This will be used for validating the context of chat messages for Player Reports

    • This chat type parameter is now used by msg_command_outgoing
