The Apache Log4j 2 team is pleased to announce the Log4j 2.8.1 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.

This release primarily contains bugfixes and minor enhancements. More =
details on the new features and fixes are itemized below.

Note that subsequent to the 2.6 release a minor source incompatibility =
was found due to the addition of new methods to the Logger interface. If =
you have code that does:

logger.error(null, =E2=80=9CThis is the log message=E2=80=9D, =
throwable);
or similar with any log level you will get a compiler error saying the =
reference is ambiguous. To correct this either do:

logger.error(=E2=80=9CThis is the log message=E2=80=9D, throwable);
or

logger.error((Marker) null, =E2=80=9CThis is the log message=E2=80=9D, =
throwable);
The Log4j 2.8.1 API, as well as many core components, maintains binary =
compatibility with previous releases.

Apache Log4j 2.8.1 requires a minimum of Java 7 to build and run. Log4j =
2.3 was the last release that supported Java 6.

Basic compatibility with Log4j 1.x is provided through the log4j-1.2-api =
component, however it does not implement some of the very implementation =
specific classes and methods. The package names and Maven groupId have =
been changed to org.apache.logging.log4j to avoid any conflicts with =
log4j 1.x.

For complete information on Apache Log4j 2, including instructions on =
how to submit bug reports, patches, or suggestions for improvement, see =
