== Release Notes

This release provides a continuation of the modularisation process of
Log4j Core.

The following features were moved to separate artifacts:

* The async logger feature was moved to `log4j-async-logger` and it
was upgraded to use LMAX Disruptor 4.x.
The async appender is still available by default in `log4j-core`.
* The YAML configuration is available now in `log4j-config-yaml`.
* The Java properties configuration was removed and replaced with a
similar format based on `jackson-dataformat-properties` in a new

`log4j-config-properties` artifact.


Other features were removed:

* Jetty 9.x users are encouraged to migrate to Jetty 10.x or later and
replace `log4j-appserver` with `log4j-slf4j2-impl`.
* Tomcat JULI support will be available from a third-party (cf.
https://github.com/copernik-eu/log4j-plugins 
<https://github.com/copernik-eu/log4j-plugins>).
* Apache Commons Logging users are encouraged to upgrade
`commons-logging` to version 1.3.0 or later and remove `log4j-jcl`.
* Support for the XML layout was dropped.
* Support for JMX was dropped and will be replaced with a more recent
technology.
