Known issues & safety notes

Preview builds are experimental: they can corrupt or irreversibly upgrade worlds, and most plugins and mods do not support them yet. Test on a copy of your world.
Log4Shell (CVE-2021-44228): for vanilla 1.12–1.16.5 Mojang says to download log4j2_112-116.xml into the server folder and add -Dlog4j.configurationFile=log4j2_112-116.xml to the start command (Mojang advisory).

How to set up Quilt 1.16 Pre-Release 6

Install Java 8 or newer (e.g. Eclipse Temurin) and check it with java -version.
Download the official Quilt installer (quilt-installer-0.15.1.jar) above.
In an empty folder run: java -jar quilt-installer-0.15.1.jar install server 1.16-pre6 --download-server --create-scripts --install-dir=server
The installer downloads the vanilla 1.16 Pre-Release 6 server, sets up Quilt Loader and writes start scripts into server/. Start it once, then accept the EULA in eula.txt.
Put Quilt (and most Fabric) mods into server/mods/.

Modded servers need more memory: 6–8 GB for a light modpack, 8–12 GB or more for large packs. Leave 1–1.5 GB for the operating system. How much RAM?
