The second pre-release for Minecraft Java is now available. In this pre-release, we've upgraded the Java version that is bundled with the game, and the game now uses Java 17. Other than this, we've mostly been busy fixing bugs.
Enjoy!
Edit: We've now released 1.18 pre-release 3 with additional bugfixes and some performance improvements. In case you missed it, we've also announced the release date for 1.18! The update is set to release on November 30th, and you can read more about that here. Mark your calendars!
Edit: We've now released 1.18 pre-release 4 with fixes for crashes in the Nether and End dimensions.
