## Release Notes Summary

This release terminates the modularization process of Log4j Core, by 
moving all
the code that uses optional `log4j-core` dependencies into new modules:

* Support for the JAnsi library has been removed since recent Windows OSes
   support ANSI escape sequences.
   See ANSI styling on Windows[2] for more details.

* The `DisruptorBlockingQueue` queue factory[3] has been moved to a new
   `log4j-conversant` artifact[4].

* Support for advanced compression algorithms[5] has been moved to a new
   `log4j-compress` artifact[6].
   The Gzip and Zip formats are still supported out-of-the-box.

### Separate lifecycle

* The Flume Appender[7] releases will follow their own lifecycle.

* All the logging bridges[8] from and to Log4j API have been removed 
from the
   Log4j Core 3.x releases.
   Please manage your dependencies with `log4j-bom`[9] to always use the
   appropriate version of the logging bridges.
