[ANNOUNCEMENT] Log4j 2.14.1 released

The Apache Log4j 2 team is pleased to announce the Log4j 2.14.1 release!

Apache Log4j is a well known framework for logging application behavior. =
Log4j 2 is an upgrade to Log4j that provides significant improvements =
over its predecessor, Log4j 1.x, and provides many other modern features =
such as support for Markers, lambda expressions for lazy logging, =
property substitution using Lookups, multiple patterns on a =
PatternLayout and asynchronous Loggers. Another notable Log4j 2 feature =
is the ability to be "garbage-free" (avoid allocating temporary objects) =
while logging. In addition, Log4j 2 will not lose events while =
reconfiguring.

The artifacts may be downloaded from =
https://logging.apache.org/log4j/2.x/download.html.

This release contains a number of bug fixes and minor enhancements which =
are listed below.

Due to a break in compatibility in the SLF4J binding, Log4j now ships =
with two versions of the SLF4J to Log4j adapters. log4j-slf4j-impl =
should be used with SLF4J 1.7.x and earlier and log4j-slf4j18-impl =
should be used with SLF4J 1.8.x and later. SLF4J-2.0.0 alpha releases =
are not fully supported. See =
https://issues.apache.org/jira/browse/LOG4J2-2975.

The Log4j 2.14.1 API, as well as many core components, maintains binary =
compatibility with previous releases.
