| <p>This is the twelfth GA release. |
| It is primarily a bugfix release. |
| More details on the fixes are itemized below.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that subsequent to the 2.6 release a minor source incompatibility was found due to the addition of new methods to the <code>Logger</code> interface. |
| If you have code that does:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error(null, “This is the log message”, throwable);</code></pre> |
| </div> |
| </div> |
| <div class="paragraph"> |
| <p>or similar with any log level you will get a compiler error saying the reference is ambiguous. |
| To correct this either do:</p> |

| <div class="content"> |
| <pre class="highlight"><code class="language-java" data-lang="java">logger.error(“This is the log message”, throwable);</code></pre> |

| <p>Log4j 2.6.2 maintains binary compatibility with previous releases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Log4j 2.6.2 requires a minimum of Java 7 to build and run. |
| Log4j 2.3 was the last release that supported Java 6.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Basic compatibility with Log4j 1.x is provided through the <code>log4j-1.2-api</code> component, however it does |
| not implement some of the very implementation specific classes and methods. |
| The package names and Maven <code>groupId</code> have been changed to <code>org.apache.logging.log4j</code> to avoid any conflicts with Log4j 1.x.</p> |
| </div> |
