+## log4j2.xml
+March 2025 brings a new implementation of log4j2.xml. We're now using the default configuration from the [server repo](https://github.com/LabKey/server/blob/develop/server/embedded/src/main/resources/log4j2.xml), and overwriting that as needed with the local log4j2.xml file in this repo. During startup, entrypoint.sh copies the local file into the configs directory after the jar has been opened up.
