<div class="paragraph">
<p>This release contains several bugfixes and new features.
The new features include new logging API modules for Scala 2.10 and 2.11, and support for various non-blocking queue implementations in <code>AsyncAppender</code>.
Furthermore the <code>ThreadContext</code> map can now be configured to be garbage-free, and users can now inject context data from other sources than <code>ThreadContext</code>.
Context data values can be any <code>Object</code>, not just <code>String</code>s.
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>
<div class="listingblock">
<div class="content">
<pre class="highlight"><code class="language-java" data-lang="java">logger.error(“This is the log message”, throwable);</code></pre>
</div>
</div>
<div class="paragraph">
<p>or</p>
</div>
<div class="listingblock">
<div class="content">
<pre class="highlight"><code class="language-java" data-lang="java">logger.error((Marker) null, “This is the log message”, throwable);</code></pre>
</div>
</div>
<div class="paragraph">
<p>The Log4j 2.7 API, as well as many core components, maintains binary compatibility with previous releases.</p>
</div>
<div class="paragraph">
<p>Log4j 2.7 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>
<div class="paragraph">
