    IF THIS FILE DOESN'T HAVE A `.ftl` SUFFIX, IT IS AUTO-GENERATED, DO NOT EDIT IT!

    Version-specific release notes (`7.8.0.adoc`, etc.) are generated from `src/changelog/*/.release-notes.adoc.ftl`.
    Auto-generation happens during `generate-sources` phase of Maven.
    Hence, you must always

    1. Find and edit the associated `.release-notes.adoc.ftl`
    2. Run `./mvnw generate-sources`
    3. Commit both `.release-notes.adoc.ftl` and the generated `7.8.0.adoc`

[#release-notes-2-0-2]
== 2.0.2

Release date:: 2014-08-16

This is the third GA release which contains several bugfixes from the previous release.

Apache Log4j 2.0.2 requires a minimum of Java 6 to build and run.
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 http://logging.apache.org/log4j/2.x/[the Apache Log4j 2 website].

* Clarified in documentation that SLF4J API jar is required when using log4j-slf4j-impl. (https://issues.apache.org/jira/browse/LOG4J2-723[LOG4J2-723])
* Prevent application from hanging when PatternLayout configuration has opening '{' but no closing '}'. (https://issues.apache.org/jira/browse/LOG4J2-726[LOG4J2-726])
* Emit warning message to console if no configuration file found. (https://issues.apache.org/jira/browse/LOG4J2-729[LOG4J2-729])
* Prevent JUnit test from creating unnecessary Log4j2Plugins.dat during build. (https://issues.apache.org/jira/browse/LOG4J2-756[LOG4J2-756])

* Improve warning message when missing log4j-core in the classpath. (https://issues.apache.org/jira/browse/LOG4J2-765[LOG4J2-765])
