This is a bugfix release of Helidon. It is recommended for all users of Helidon 2.
Compatibility
2.4.1 is API compatible with 2.3.0.
log4j
Helidon itself does not use log4j, and by default will not include log4j on
your application's classpath. But Helidon does manage the version of log4j and
uses it in some examples and the helidon-logging-log4j integration feature. This
release of Helidon upgrades this managed version to 2.17.0.
