Apache Log4j ${relVersion} RELEASE NOTES
The ${developmentTeam} is pleased to announce the Log4j ${relVersion} 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 several bugfixes and new features. The new features include the ability
to have the RollingFileAppender log directly to the archive files. 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, This is the log message”, 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(“This is the log message”, throwable);
or
logger.error((Marker) null, This is the log message”, throwable);
The Log4j ${relVersion} API, as well as many core components, maintains binary compatibility with previous releases.
## Hack to improve layout: replace all pairs of spaces with a single new-line
$release.description.replaceAll(" ", "
")
#if ($release.getActions().size() == 0)
No changes defined in this version.
#else
Changes in this version include:
#if ($release.getActions('add').size() !=0)
New features:
#foreach($actionItem in $release.getActions('add'))
## Use replaceAll to fix up LF-only line ends on Windows.
#set($action=$actionItem.getAction().replaceAll("\n","
"))
#if ($actionItem.getIssue())
#set($issue=$actionItem.getIssue())
#else
#set($issue="")

Apache Log4j ${relVersion} 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.
