This patch release contains only the fix of a log4j-jcl bug that prevents it from connecting with commons-logging.
The Log4j 2.21.1 API, as well as the other artifacts, maintains binary compatibility with the previous release.
Apache Log4j 2.21.1 requires Java 8 to run.
The build requires JDK 11 and generates reproducible binaries.
For complete information on Apache Log4j 2, including instructions on how to submit bug reports, patches, get support, or suggestions for improvement, see the Apache Log4j 2 website.
