'''1.18.1''' is a minor update to {{JE}}, released on December 10, 2021, which makes minor changes related to fog and fixes bugs.<ref>{{Mcnet|minecraft-java-edition-1-18-1|Minecraft Java Edition 1.18.1|December 10, 2021}}</ref> It is compatible with [[Java Edition 1.18|1.18]] servers.
Most importantly, this version fixes a zero-day security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. As a result, players were urged to secure their clients and servers.<ref name="article_log4shell_vulnerability">{{Mcnet|important-message--security-vulnerability-java-edition|Important Message: Security vulnerability in Java Edition|December 10, 2021}}</ref>
While this wasnt the last update to 1.18, it was the last one of 2021 and the last before the development versions of [[Java Edition 1.19|1.19]] started.
== Changes ==
