This page covers a development version that has a major issue under certain conditions.
 
The dedicated server for this version has a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.[1]

Combat Test 4 is the fourth experimental version of a future combat revision.[2] Although it is a version for a future revision, this combat experiment is a fork of 1.15 Pre-release 3. This version was released only on Reddit, so it does not appear in the launcher or in any Minecraft.net blog post. This is the final combat test released in 2019.
