The Apache Log4j 2 team is pleased to announce the Log4j 2.11.0 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 contains new features, bugfixes and minor enhancements.
As of Log4j 2.9.0, the Log4j API was modified to use =
java.util.ServiceLoader to locate Log4j implementations, although the =
former binding mechanism is still supported. The Log4j API jar is now a =
multi-release jar to provide implementations of Java 9 specific classes. =
Multi-release jars are not supported by the OSGi specification so OSGi =
modules will not be able to take advantage of these implementations but =
will not lose functionality as they will fall back to the =
implementations used in Java 7 and 8. More details on the new features =
and fixes are itemized below. Note that some tools are not compatible =
with multi-release jars and may fail trying to process class files in =
the META-INF/versions/9 folder. Those errors should be reported to the =
tool vendor.
Note that subsequent to the 2.9.0 release, for security reasons, =
SerializedLayout is deprecated and no longer used as default in the =
Socket and JMS appenders. SerializedLayout can still be used as before, =
but has to be specified explicitly. To retain old behaviour, you have to =
change configuration like:
<Appenders>
<Socket name=3D"socket" host=3D"localhost" port=3D"9500"/>
</Appenders>
into:
<Appenders>
<Socket name=3D"socket" host=3D"localhost" port=3D"9500">
<SerializedLayout/>
</Socket>
</Appenders>
We do, however, discourage the use of SerializedLayout and recommend =
JsonLayout as a replacement:
<Appenders>
<Socket name=3D"socket" host=3D"localhost" port=3D"9500">
<JsonLayout properties=3D"true"/>
</Socket>
</Appenders>
Note that the XML, JSON and YAML formats changed in the 2.11.0 release: =
they no longer have the "timeMillis" attribute and instead have an =
"Instant" element with "epochSecond" and "nanoOfSecond" attributes.
Note that subsequent to the 2.9.0 release, for security reasons, Log4j =
does not process DTD in XML files. If you used DTD for including =
snippets, you have to use XInclude or Composite Configuration instead.
The Log4j 2.11.0 API, as well as many core components, maintains binary =
compatibility with previous releases with the following exceptions to =
Log4j Core. Log4j 2.11.0 moves code from log4j-core to several new Maven =
modules. Dependencies to other jars that used to be optional in =
log4j-core are now required in the new modules. The code in these =
modules have been repackaged. These changes do not affect your =
configuration files.
The new modules are:

Apache Log4j 2.11.0 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 =
