What you need to know

  • Mojang Studios is working on the 1.19.1 patch update for Minecraft: Java Edition.
  • The update will include dozens of fixes and improvements, and even some new features.
  • On Friday, the studio released Minecraft: Java Edition 1.19.1 Pre-Release 4 testing more of these fixes.
  • If testing of this build goes well, the 1.19.1 update should go back to release candidate builds in the near future.

The march to Minecraft: Java Edition's 1.19.1 update is continuing with more pre-release testing. Mojang Studios is finalizing the extensive patch update with further polish and last minute fixes, culminating in Friday's Pre-Release 4 snapshot. This snapshot features a handful of changes and fixes targeting the game's chat systems.

Mojang Studios is releasing this snapshot right on the heels of the preceding Pre-Release 3 snapshot with a more modest changelog. If testing of this release goes well, Mojang Studios should begin testing more final release candidate snapshots. The final 1.19.1 update will include plenty of improvements, and even new features, built on top of Minecraft 1.19 "The Wild Update."

Even without considering its never-ending support cycle, Minecraft would still dominate the list of the greatest and most successful PC games. The latest snapshot isn't particularly exciting, but it improves the security of Minecraft's in-game chat, and adds to the dozens upon dozens of changes tested in previous 1.19.1 snapshots. If all goes well, the final update should arrive within the next few weeks.
