3.0.0-beta3

on GitHub

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 for more details.
• The DisruptorBlockinQueue queue factory has been moved to a new log4j-conversant artifact.
• Support for advanced compression algorithms has been moved to a new log4j-compress artifact.
  The Gzip and Zip formats are still supported out-of-the-box.

Separate lifecycle

• The Flume Appender releases will follow their own lifecycle.
• All the logging bridges from and to Log4j API have been removed from the Log4j Core 3.x release.
  Please manage your dependencies with log4j-bom to always use the compatible version of the logging bridges.
