$h1 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.

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

This release contains bugfixes and minor enhancements.

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.

New features include support for reconnfiguration of Log4j configuraton files accessed via HTTP(s) and Spring Cloud
Config specifically,  a new Docker Lookup for obtaining information about the current Docker container, new
reconfiguration methods added to the Configurator class, the
ability to pad integers with leading zeros in filenames generated by the rolling file appenders, and allowing the TCP
SocketAppender to connect to mulitple ip addresses when they are returned from DNS.

More details on the new features and fixes are itemized below.

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.

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

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.

reports, patches, or suggestions for improvement, see the Apache ${project.name} website:
